Efficient and professional. Answered all of my questions!

Joe was great, worked quietly and efficiently. Explained everything he did, and answered my questions. Did an awesome job!!

Our heating and plumbing technicians, Nick Lenzi and Domingo Clemdaniel, were amazing. They were on time, courteous, and addressed our questions or concerns promptly. Thank you!

Oscar was very pleasant to talk to and, more importantly, he spent time making sure everything was hooked up right and the appliances were working properly. He was very punctual and made sure to clean up after the job was completed. I am going to use Donnelly’s for every future plumbing work…and I’m going to ask to send Oscar, if possible.

We had some water issues in our basement near the sump pump so I contacted Donnelly’s who is my go-to. Nick Lenzi arrived on time, quickly diagnosed and explained the issue for a layman like me, and identified a menu of options, mindful of my wallet but also of the long term maintenance needs for our home. Once we landed on the repair plan, Nick began executing what needed to be done quickly and efficiently all while explaining what he was doing along the way. In addition to the quality craftsmanship, Nick was a pleasure to have in my home with easy casual conversation while also being mindful of our property and my time while working from home. I would gladly welcome Nick back for future plumbing projects.

Caleb was very knowlegable in his craft. He diagnosed the problem quickly, offered options, then made the repair timely. Very respectful and cleaned up so it was as if he was never there. Great job, Caleb!

Brandon came to my home and figured out what was wrong with the unit. He explained everything in detail. He definitely knows what he is doing and I had full trust in him. I highly recommend Donnelly’s and Brandon.

George did an excellent job on the annual review of my heating system.

Prompt and accurate

Daniel Juárez did a fine job doing my plumbing inspection

Nick was amazing! I very much appreciated his experience and open communication. Besides being an amazing plumber we really hit it off and I trusted him. He informs you of everything that's going on in the house, gives his honest opinion of what needs to be done urgently and what could wait. When on the job, he's very quick, neat and informs you of everything every step of the way. He even saved me from an appliance repairman visit because he was right, my high water pressure was causing the problem with my water dispenser in my refrigerator! Thanks for sending Nick my way, he's one of the good ones!

Donnelly’s is always easy to work with, very responsive and their techs are top notch! We had a furnace issue and Matthew showed up and helped put it right.

Robert was excellent! Professional, personal, and thorough! Today Brandan diagnosed the problem before he even looked at the AC unit. He explained corrective options clearly and thoroughly. And fixed the problems in a very timely manner. He explained follow up maintenance. Very professional and personable! Woke up to 50 degrees and no heat. Called John at Donnelly’s and within 2 hours Domingo was here. He diagnosed and fixed the flame detector in less than an hour. Outstanding service!

Dylan was fantastic, very pleasant and professional, fixed our heater in record time!

Kevin was prompt and efficient. He took his time to explain my situation and provided options for me to consider.

Great crew. Very professional, informative and skilled. Jobs were completed on schedule, clean-up was perfect. James Bernier answered all of our questions thoroughly and made sure all repairs were working in house prior to departure. Highly recommended ! - Eric Burgher * Well pump and all pipe and connections replace/install * Water heater replace/install

I own half a double, we were grandfathered in with a shared lateral. My basement flooded with sewage back in September, we found the whole lateral needs to be replaced. The township did the ran a sewer extension to allow connections. However the landlord of the other side has been dragging his feet, because thats how he is anything that he needs to fix or repair is months long, his gutter fell off the week before Easter, he fix it till July. Donelllys has been amazing in helping keep the sewage out of my basement until the slumlord next door gets his lateral detached. If he doesn't do it by December 26th the water gets shut off

From start to finish, the experience was fantastic. The team was prompt, professional, and incredibly knowledgeable. They explained every step of the process, answered all my questions, and made sure I understood how to get the most out of my new system. The installation itself was fast, clean, and done with real attention to detail. If you’re considering new heating or air conditioning, I can’t recommend this company enough. Top-notch service, outstanding workmanship, and true peace of mind. I’m thrilled with the results!

Prompt response and took care of all of my needs.

I had no problem with the tech, he did good work, my problem is that I had a window of 12:00 p.m. to 4:00 p.m. and the tech did not show up until 5:00 p.m. periodic updates would have been appreciated, I had to cancel plans I had for 6pm because of this inconvenience.

Great Experience! It’s hard to say things like that when you are looking at a major repair so close to the holidays. Derrik was awesome! He immediately gave us confidence in him. He is experienced, thorough, and took the time to explain everything as he went along from start to finish. Will recommend Donnelly to anyone that needs plumbing repair for sure. They do HVAC work and I would recommend them for that because I am sure that ALL of their technicians are almost as thorough as Derrik. Thank you guys

Excellent and professional service. Will refer Donnelly’s to anyone I know looking a new system or just maintenance.

Evan galo and his team were amazing! Professional, communicative, patient. The area was immaculate.

Rob was awesome! Great guest service skills, efficient and a true professional. We will be requesting him on all of our future HVAC system needs/R&M!

Joe was professional and very informative.

Travis did a great job. Knowledgeable and professional.👍

Matthew was able to troubleshoot our issue. He was methodical going through and eliminating possible causes until he found the issue. Very good work.

The technician George Espino was very nice. He explained everything he was doing in checking maintenance on my HVAC. He made me feel confident about my six month old HVAC system!

Caleb came out to replace shower head /faucet and did a wonderful job removing the old apparatus and very knowledgeable about what needed to be done and checking water pressure before beginning the job. I would highly recommended him and Donnellys for any future work. ⭐️⭐️⭐️⭐️⭐️

Brandon did a great job installing my humidifier! Works great!

Kevin McCullough did a great job! He quickly diagnosed the problem and did the repair. He was very professional and knowledgeable. I highly recommend him to anyone needing a heat pump repair.

Great plumbing knowledge and a nice guy. Answered all our questions.

Nick Lenzi completed a complicated sink and vanity replacement and installation at our house perfectly. He went above and beyond to replumb the existing (old) plumbing drain and water pipes, and to retrofit the cabinet. He is highly professional, skilled, and a pleasure to work with. Highest recommendation!

Called for plumbing service and had a service person here within an hour. Great service.

The employee was courteous, honest, and knowledgeable.

I needed a new HVAC system for my townhouse. After doing my homework, I ended up going with the same company I’ve been using for my regular maintenance for the past 11 years. Donnelly’s. Heating and Air, I’ve always had a good experience with them and their pricing was exactly what I was looking for. Wade came to my house and went over all the options with me and two days later the crew came out to do the installation and all went in perfectly. Overall great experience.

The technician took out the time to be thorough, and resolve my issue with my heating system.

Excellent service. Team was responsive and out to my house within 24-hr for a non-emergent issue. Nick was our technician and was extremely knowledgeable, kind, and honest about the issue at hand and addressed the problem easily while talking through his thought process. This is what local / community service providers should be like. Definitely working with Donnelly’s again in the future.

Very nice

Donnelly's heater maintenance check up: Joseph was fantastic. Very professional and thorough. Thank you!

As usual he was great. Pleasant, helpful, informative as usual. You guys have the best oeople.

Duane the Tech was very efficient and helpful.

Annual plumbing inspection. Quick, thorough and friendly. I'm happy with Donnelly's service.

Excellent and timely service. Mr. Lenzi came out to help us and was both polite and very knowledgeable. He went over ever step making certain we knew and understood what our options were. Nicholas is exemplary of why we have in the past and continue to trust Donnelly with our business.

Shane was excellent in reviewing my plumbing throughout my house. Took pictures and videos of potential issues. Extremely professional in every way. Explained everything in a logical and easy way to understand. Have used Donnelly in the past for Heater and AC installation. Would highly recommend Shane and Donnelly.

I had to have a new HVAC system installed in my home. Evan was excellent in all facets of the process. He was very patient with my many questions regarding the system. I highly recommend him and Donnelly’s in general for many home system repairs and installations

I recently had Joe from Donnelly's Plumbing come by to replace the expansion tank on my hot water heater, and I couldn't be more pleased with the experience. Joe was professional, friendly, and efficient, and the pricing was fair and transparent. I highly recommend Joe and Donnelly's Plumbing for any plumbing needs!

Excellent job and speedy service.! Sebastian the repairman was very friendly and professional.

Our hard water softener started malfunctioning and Travis came same day to help fix the issue.

Stanley did an excellent job. He explained everything when the heater was installed. They did a really good job of making sure everything was clean when they finished. Thank you.

James B. was extremely through. He explained every issue in detail. He was friendly. He was courteous. He knew his job incredibly. Highly impressed w him & his work.

Called Donnelly for an issue that popped up during a bathroom renovation, and they were able to send someone out within hours to assess the situation. Domingo did a great job! Explained everything, kept me informed of the progress, and quickly communicated any issues. Friendly, courteous, and professional! Highly recommended!

Responsive and knowledgeable Thanks! Really nice install, nice products, staff was great, next day install was nice as well

So far my experience with Donnelly & Joseph has been outstanding. I would highly recommend them as a premier HVAC company

Sebastian Bernier was on time, professional, knowledgeable and answered our questions and concerns. He worked very neatly & clean, and offered us optional payment plans that were very good. He was at our home to replace a Water Softening System, took all of the components of the old one with him. A very competent & polite young man. All of the folks that I have dealt with from Donnelly’s have been great ! Whether it’s people answering calls or coming to do the job at hand, all excellent !! Thank you all so much, and keep up the excellent work !!

The crew was great, friendly and answered any and all questions I had

Excellent service. I will definitely use them again.

A repeat customer completely pleased with our experience. The professionalism and care put into fixing our issue quickly and efficiently is very appreciated.

George was great and worked very efficiently when he was here.

Knowledgeable, friendly, and clean

Our plumber this morning was excellent and worked professionally to clear bathroom sink drain and explain the work. Thank you. Leon chain

Very happy with service. The guys were very careful of property. Explained every to us and let us know if there were other questions to just call. Would recommend for all services.

Kevin was very thorough and got everything done in several hours.

The technicians/ installers were pleasant, knowledgeable, polite young men. A positive experience all around. Glad i chose Donnelly's to install a new heater and air conditioner.

Great company for hire, highly recommended, Thank you, very pleased

Punctual, professional, clean, fair pricing, dependable

We were very satisfied with Nick and his work was outstanding. We felt very trusting and comfortable in his presence as well. What a joy and we are impressed!

What a great job by Donnelly’s Plumbing. The most amazing part was same day service with excellent work. Plumber Nick Lenzi explained our options in detail, and installed new piping to repair our shower. Nick and Donnelly was a wonderful surprise and we continue to call them for future needs. Thank you.

The technician Khali explained very well what the heater check was and went over his findings when complete. He provided excellent information explaining his recommendations and why. I would highly recommend Donnelly’s for checking & servicing your HVAC.

Nick is a credit to your company. He was polite, informational, and thorough. We thank you for your quick response. I will recommend Donnelly to my family and friends.

Team was ontime. They took their time to protect my floors. They kept me informed on progress and cleaned up very well.

Robert was excellent! Professional, personal, and thorough! Today Brandan diagnosed the problem before he even looked at the AC unit. He explained corrective options clearly and thoroughly. And fixed the problems in a very timely manner. He explained follow up maintenance. Very professional and personable!

They were great

Response time was phenomenal! We called on a Sunday, for emergency work and it was completed by Tuesday. All of the crew members communicated with us at each step and were a pleasure to work with, we cannot say enough good things about their work ethic. Great company for your emergency situation! Highly recommend!

Duane answered all my questions in terms i could understand. Very helpful and professional. He got right to the job the moment he arrived. This was a checkup for my heat system so it didn't cost anything. He offered tips of how to utilize my system. I would recommend Duane for any heater service calls. He also has a great sense of humor. Very nice man.

“Outstanding service from start to finish. The technician Khalij Whitaker arrived on schedule, walked us through all of his steps and it is very clear he takes pride in his work. We highly recommend him and Donnelly’s for any HVAC and Plumbing needs.

James arrived on-site, was able to assess the visible issue but also went deeper to find the source of the problem. Explained what was needed and always friendly and professional

Joe was quite good and thorough. He was able to shut off the water and install the new pressure release valve so we didn't have to rely on the unreliable water company tech who didn't show a couple of days ago. Joe also trouble shot a persistent pressure problem with my kitchen faucet. Checked a couple of potential sources in the faucet with no answer yet. Will return to check a valve source. Have confidence in Joe and look forward to his return, answer, and fix. .

Robert arrived to do my heater inspection. He was very efficient and pleasant. As my heater is fairly new, he only had two professional recommendations which were not urgent. I would recommend him and Donnelly going forward.

Tom is a consummate professional who instilled confidence that the job would be done right. He was clear about what needed to be done and reliably followed through to get quality work competed in short order.

Plumbing issues are never a good thing. But from the moment that I called Donnelly's and spoke to a wonderful and helpful lady to the moment when Nick Lenzi left my house with everything repaired or replaced, I could not have asked for a better experience. Truthful, efficient and good at what they do. Tremendous combination.

Donnelly's is our go-to place we need something fixed. George the technician was absolutely amazing! We've been having issues off and on for the past year and George was able to figure out what it is and it's running smoothly. My father has Alzheimer's and he can't hear and George was extremely patient and kind with him and took the time to explain everything to my father and to us. So far my experience with Donnelly's the customer service's top notch as well as their services. Had to Donnelly again, The service was top notch they were quick ,they came immediately, communication is above and beyond and the service is amazing. Khalij W is nothing short of amazing!

Stanley did an excellent job. He explained everything when the heater was installed. They did a really good job of making sure everything was clean when they finished. Thank you.

Our tech, Mr Whitaker, was very knowledgeable and did a very good job explaining the results of our maintenance inspection. He was pleasant and respectful throughout his visit.

They performed yearly maintenance and placed a flow switch in. He was very courteous and knowledgeable.

Customer service is amazing. Our plumber Nick is honest, knowledgeable and always on time.

Tony did a very good job of explaining what he was doing and went the extra mile to make sure that everything was clean and handled properly.

Mick was wonderful. He was very professional and explained everything.

Our tech was THE BEST!! I would only have him work on our system

11/11/25 Thanks to Tony Reyes for making sure my heating system performs optimally this winter…the benefit of an annual service checkup! 11/13/25 It was another thorough and professional job by James Bernier as he performed my annual plumbing checkup! I appreciate his explaining every step of the process. 3/11/25 Kevin McCullough performed a thorough check of my air conditioning system and explained everything he did in easy to understand terminology. Excellent job, Kevin! 12/3/24 I gained a real appreciation for the value of an annual plumbing service check as I experienced my first one last week. James Bernier walked me through the process and explained what he was looking for as he inspected each item. Today he returned to install a brand new water softener system to combat the issues my extremely hard water has been causing to all my appliances that use water. During installation, he discovered and repaired a leak in the main water pipe that would have certainly caused imminent damage and expense had he not identified the problem. Thanks so much, James! You’re the best! Feb 2024 James Bernier did an excellent job replacing my failed main sump pump and its backup battery. He is knowledgeable and thorough, answered all my questions and explained everything he did. I’d certainly request him for future plumbing needs.

November 17, 2025 We had Tom Gardner install a frost-free hose faucet in our garage. We have asked for Tom for several years to do any plumbing repair and for our annual plumbing checkup. We were very pleased with the work he performed for us today. He did a great job for us. October 30, 2025 Joe Fletcher performed our annual heating system check and my wife and I were very pleased and impressed with this young man. He was very personable and thorough and we continue to be very happy Donnelly customers. This is a first-rate company. August 19, 2025 We requested Tom Gardner to help us solve a loss of water pressure issue that had the potential to become a serious. When he arrived he quickly and expertly diagnosed the problem and offered an affordable solution that eliminated the problem. We have found Donnelly’s to be a company you can trust and we continue to be very happy customers. ******************* June, 24. 2025 We had Domingo Clendaniel do our annual AC checkup and as he has done in the past, provided us with excellent service. We are very pleased with the service provided to us by Donnelly’s. Domingo is a credit to the company, providing us with 5-star service that we completely trust. ************************* June 11, 2025 We had Tom Gardner do our annual plumbing inspection. I feel sure that Donnelly’s has great plumbers and HVAC technicians, but we alway ask for Tom for any plumbing inspection or need. He is exceptionally skilled, honest, kind and very thorough. I always feel confident in any plumbing suggestion he might make for our home because my wife and I trust him completely. Donnelly’s continues to provide us with five-star service for our plumbing and HVAC needs. We continue to be very pleased with the service provided to us. ************************* January 18, 2025 My wife and I noticed the air coming out of our heating ducts was cool so we called the office Saturday morning. With a cold snap approaching we wanted to be sure our equipment was working. Natajia (I think I got the spelling of her name right) took the call and although only two technicians were on duty on Saturday, managed to get us on the list for that afternoon. She was really great. Justin Cooper came out, quickly diagnosed the issue (it was not a major one) and took care of the problem in about 15 minutes. We were very thankful and appreciative. Justin was very knowledgable, explaining in detail to my wife and me the problem and how he fixed it for us. The heat was back on with no further issues. We have had a service contract with Donnelly's for many years and we have recommended Donnelly's to our friends and colleagues without reservation. September 17, 2024 Domingo Clendaniel serviced our heating system to get the house ready for the winter and once again, we could not be more pleased with the services he provided. We continue to be impressed with the services Donnelly's provides us for our HVAC needs. This is a great company! ******************************************************* July 8, 2024: Tom Gardner performed our annual plumbing check up and once again, we could not be more pleased with the service he provided. Professional, courteous, knowledgeable, and so trustworthy. My wife and I continue to be impressed with the service Donnelly's provides us for our HVAC and plumbing needs. We completely trust that any work recommended to be done as preventative maintenance actually needs to be performed. The quality of the services provided continues to be top notch, and we would recommend Donnelly's to our friends and colleagues without reservation.

Nicholas Romanowski from Donnelly’s installed a water booster for us and was excellent and informative! He was very professional, friendly and skilled from the point of initial evaluation and estimate, all the way through installation. Great experience!

I have had the privilege of using Donnelly’s for several large and small projects all of which they have excelled in service. I will never use another company to handle my plumbing or HVAC projects. I needed the gas line behind my new stove shortened so that it would sit flushed against the wall. Dylan was great. He came for the initial assessment a few days prior and returned to complete the project. Dylan was on time and had a pleasant attitude. He was super quick with changing out the line. Thanks Donnelly for another pleasant experience.

I appreciate his candor and respectfulness with which he does his job. I highly recommend Donnelly’s to anyone with plumbing needs. Nicholas Romanowski was outstanding. I‘ve used him before and I would use him again N.M.

Great service on a Saturday afternoon they got the water heater replaced within hours despite a few challenges.

Khalij was great with the plumbing pipe installation!

Great job, on time Very pleasant person. Exceptionally good at diagnosis and explaining the issues. First rate technician

I have used Donnelly’s for many years.I have always found them to be honest and fair, upfront pricing. Very professional and helpful. The staff is awesome!!

Can’t recommend Jameel and his crew enough. Extremely professional and friendly. His crew took their time to walk me through any questions I had.

Had my central ac unit serviced and cleaned today. James Wagner, the tech from Donnelly HVAC was kind, informative, well spoken, and dressed in clean uniform. He put foot protectors on his shoes, and walked around my house, not through it, with his gauges. I knew how much the services he recommended would cost me before any work was done. I will definitely use Donnelly’s services again!

Today Joe Fletcher completed my annual heating inspection. He contacted before arriving and arrived ahead of the scheduled time. He was quick, thorough and neat in his inspection and explanations.

Excellent technician!

Annual plumbing inspection. Quick, thorough and friendly. I'm happy with Donnelly's service.

The service technician James B. was very helpful and professional.

I called Donnelly's for some pipe work in my basement at 10AM, and they were at the house 40 minutes later. Technician Shane worked with me to find the right solution and the right price, then completed the work right away. He went over and above to get the job done right, and the way I needed it.

Robert was great! Was out within a couple of hours and fixed things quickly and affordably. Also didn’t mind curious kids running around!

The technician, George, was very good. He was quick and efficient and left the area perfectly clean. Helped with a filter issue and explained something regarding how to best use humidifier I did not know about.

No heat. No problem. They came out within six hours after I called. Fixed the problem. Now I’m toasty warm!

We have used Donnelly’s for several projects in the past and would continue to use them for all of our HVAC needs. Robert, who handled this job for us arrived when expected, explained what needed to be done, and gave us what the cost was going to be. He completed the job thoroughly and in a reasonable time frame. I would highly recommend their service.

Shane was super friendly and helpful and got the job done so quickly! He made us feel completely comfortable with both his service and the final product. Thanks to him, we will only be using Donnelly’s for our plumbing, cooling, and heating needs!

Khalij was great! He was knowledgeable and courteous.

Great experience. Knowledgeable, clean and effective. Highly recommended

The service tech was fine. My issue was that my appointment was for 8:00am-9:30am, and received a call at 8:52am advising that my appointment should not have been made. The tech will be out at 11:00am. Would have liked to have known this issue before the original appointment time.

Donnelly's is a real good company. We had Donnelly's come out and evaluate our heating furnace. Brandon did a wonderful job on diagnostics and gave solid, honest advice. We also had their electrical service (new to Donnelly's) used to give input on how to improve our system. Joe did this work and was also phenomenal. Donnelly's is solid.

Joe did a great job, quick and efficient. Thanks

Nicholas R. took the time to explain the problems with the hot water heater, the water softener and patiently showed me how to prevent future problems. Plus he explained that the softened ceiling was due to wetness and not a continuous leak and didn’t take on a job that was not necessary, saving me a lot of money. I highly recommend Donnelly’s to anyone with plumbing needs. Nicholas Romanowski was outstanding and honest. N.M.

Our entire experience with the team at Donnelly was outstanding from service to sales and institutional. We purchased a new heating and air conditioning units. Their attention to detail was very impressive.

First time using them Timely and professional Gave all options and price before work was started Completely satisfied

Donnelly's is our go-to place we need something fixed. George the technician was absolutely amazing! We've been having issues off and on for the past year and George was able to figure out what it is and it's running smoothly. My father has Alzheimer's and he can't hear and George was extremely patient and kind with him and took the time to explain everything to my father and to us. So far my experience with Donnelly's the customer service's top notch as well as their services. Had to Donnelly again, The service was top notch they were quick ,they came immediately, communication is above and beyond and the service is amazing. Khalij W is nothing short of amazing!

Everything went well and Grorge explained everything so I would understand

This company is great to work with. Always looking out for doing whatever is needed

Rob was very friendly and professional. Patient with us. Explained everything in detail.

Great technician. Very personable and fair. Highly recommend Duane

As a feature of my Comfort Protection Plan, I just received a free plumbing inspection. Tom inspected all plumbing and made recommendations that were really helpful. He quickly replaced a flush valve flapper and the cost was really reasonable. I had a few questions, and he provided detailed answers. I am so pleased with the service I have received from Donnelly’s. Duane and Matt for ac and now Tom for plumbing—all great! Also, everyone in the office is helpful, too! Nov 7: Adding to my above review, Joesph Fletcher just inspected my heating system and spent time making sure all radiators are properly warming and the system is in tip-top shape! Great service!

Very professional, timely intervention and going extra miles to deliver an excellent service. Altogether, very pleased with Donnelly’s services and dedication of Duane to do everything to get the problem solved. Excellent job!

Kevin was very friendly, knowledgeable and forthcoming during his inspection of our furnace. I was very satisfied with the service he provided.

Donnelly’s provided exceptional service from start to finish! I called them during an emergency flooding situation, and they had a team at my home the very same day to fix it. The next day, they performed a camera inspection that revealed an issue with the outdoor sewer line that could cause the problem to recur. They came back the following day to fix it. The repair process required obtaining a township permit and passing an inspection, which Donnelly’s handled seamlessly. Everything was completed efficiently and to the highest standard. Throughout the entire experience, every person I dealt with, including Dan, Mike, Joe, and the kind person who answered my initial call, was professional, knowledgeable, and genuinely helpful. The team members who worked inside my home were respectful and careful. I appreciate their quick response and high-quality work. I wouldn’t hesitate to call Donnelly’s again and highly recommend them to anyone in need of reliable plumbing services!

Professional, polite and clean. This was the best experience I've had in a long time with a AC company. Really Appreciated the loaner unit for the bedroom, no one else offered that.

Dylan was wonderful! Great with my dogs and so considerate of my newborn baby. He was efficient and very kind. The work was reasonably priced as well!

Travis was professional, knowledgeable and helpful.

Professional, capable and thorough. Just perfect.

We had a wonderful experience with Shane Galvin. He was personable, knowledgeable, professional, and upfront with us. He answered any and all questions we had and was very helpful. He was extremely considerate of our home and not only made sure to leave any mess to a minimum, I think he also may have left our house slightly cleaner than it was when he arrived. He did an absolute stellar job, informed us of everything he was doing, and we couldn’t be happier with the work he did. If we ever have more plumbing issues, which I’m sure we will, Shane is the only plumber we want. Five stars are all around!

My service worker Travis is friendly and extremely knowledgeable. He left the space in better condition than he found it. I am completely happy with his expertise and professionalism.

Khalij was in time and professional. He did preventive maintenance on our heating system. Would recommend

The technicians/ installers were pleasant, knowledgeable, polite young men. A positive experience all around. Glad i chose Donnelly's to install a new heater and air conditioner.

Excellent service very professional employees top notch

Very professional and great service

Fantastic Service! Shane is the Plumber to Request! ​I recently had an appointment for a toilet repair, and Shane was the technician sent out. I couldn’t be more pleased with the entire experience. ​From the moment he arrived, Shane was incredibly respectful and professional. It was immediately clear that he is highly knowledgeable and quickly diagnosed the issue, explaining the necessary fix clearly and efficiently. ​Beyond his technical skills, the level of customer service was the absolute best. He was courteous, tidy, and made the entire repair process stress-free. ​I will definitely be requesting Shane by name for any plumbing work I need done in the future. He’s a true professional and highly recommended!

Donnelly”s just st an installed a new gas furnace and a smart thermostat. Their entire team, from George the The initial service man who detected the problems with my 20-year-old furnace to Eric, who took us through the sales process to Jeff who installed the furnace we’re all professional and informative making sure that we understood all the alternatives before making a decision. Jeff, the installer did an immaculate job and make sure that we understood exactly what we needed to do in order to maintain a comfortable temperature in the house. It was a pleasure dealing with all of them

Matt did a great job! Very knowledgeable! Keep up the good work.

Excellent job and speedy service. Caleb, the repairman was very friendly and professional.

Shane came out to a job we were working on a Saturday to repair the water line pipe that broke. Fixed it fast! Thank u.

Derek did a great job and was very professional and courteous. Only concern is Donnelly’s pricing schedule.

Dylan was prompt, knowledgeable, efficient, and courteous. A great representative of Donnelly.

I was very pleased with Nick’s work. But, also with his explaining every detail of what he was going to do as well as some other important plumbing tips.

Oct 2025 - Tony Reyes came out to do a hearing system inspection. He was professional and polite. He advised on 2 improvements which I put under consideration for later. I am gun shy now. Oct 2025 - they returned to correct the original plumbing issue and it was a quick solve which made me question my prior spend of $2k. Sept 2025 - I had a plumbing issue with a toilet and they came out and I ended up paying for $2k of repairs resulting from my subpar builder but was told it caused the issue I was having. All of the repairs however did not resolve my original issue. 😐 July 2025 - Justin Henry came out to perform an AC inspection. He was on-time, courteous, and thorough. I now know about possible upgrades I can add to my systems but also that my AC is good condition. Holding at 4 stars. March 2025: Joseph Garber came out for a plumbing inspection which is a covered service for the $20/monthly fee I pay. He was professional, personable, punctual and just nice. All of their service reps should have some of the “P”s listed above. Adjusted my review rating from 2 stars to 4 stars. Jan 2025: Horrible experience with the last service visit by Kevin McCullogh. He arrived without a service appointment while I was at work but my son was at home. My son let him in to do the work when he couldn’t reach me at work. The service was done well but it was an hot mess with the payment. I had to call the main office from work to make arrangements. All of this made my son late for his college class because none of it was planned. Not the experience I am used to. Disappointed and I am doubting using them for another service I was considering.

The team of 3 that was here to replace my sewer line were extremely confident in what they were doing. They kept we well informed and worked very well as a professional team. They were polite and workmanship was wonderful. All was cleaned up before they left. I would definitely use this crew again no doubt. Give them 5 stars for sure.

Great service job by Brandon today. He was very informative on the 2 furnace units we had checked today to make sure good for the winter. He explained things clearly and concisely. Highly recommend!

Tony did great job.He was helpful in explaing was going on Frank&Georgia

I needed a new HVAC system for my townhouse. After doing my homework, I ended up going with the same company I’ve been using for my regular maintenance for the past 11 years. Donnelly’s. Heating and Air, I’ve always had a good experience with them and their pricing was exactly what I was looking for. Wade came to my house and went over all the options with me and two days later the crew came out to do the installation and all went in perfectly. Overall great experience.

Shane did a great job today! We were in a jam with both our main and backup sump pump failing and the water starting to overflow the sump well. He was super professional and efficient. Very happy with the result. Shane saved our finished basement.

We had the best experience with Travis. He Explained every detail that would be done. He offered suggestions and never once tried to push us to make a decision either way. His personality was A+

George was great, very professional!

Very knowledgeable and did great work.

I had a great experience! As a first time customer my service fee was waived and I received same day service. Shane showed up on time, walked me through the process ensuring I understood the existing problem and all options for repair. I’m very happy with the finished product and I received a military discount!

All the technicians were courteous and did an excellent job with my HVAC installation. They also took the time to explain the system’s operation to me.

Joe was great and very personable. Terrific workmanship too.

Nicholas was timely, professional, efficient, and informative. I would absolutely recommend him anytime!

October 30, 2025 Joe Fletcher performed our annual heating system check and my wife and I were very pleased and impressed with this young man. He was very personable and thorough and we continue to be very happy Donnelly customers. This is a first-rate company. August 19, 2025 We requested Tom Gardner to help us solve a loss of water pressure issue that had the potential to become a serious. When he arrived he quickly and expertly diagnosed the problem and offered an affordable solution that eliminated the problem. We have found Donnelly’s to be a company you can trust and we continue to be very happy customers. ******************* June, 24. 2025 We had Domingo Clendaniel do our annual AC checkup and as he has done in the past, provided us with excellent service. We are very pleased with the service provided to us by Donnelly’s. Domingo is a credit to the company, providing us with 5-star service that we completely trust. ************************* June 11, 2025 We had Tom Gardner do our annual plumbing inspection. I feel sure that Donnelly’s has great plumbers and HVAC technicians, but we alway ask for Tom for any plumbing inspection or need. He is exceptionally skilled, honest, kind and very thorough. I always feel confident in any plumbing suggestion he might make for our home because my wife and I trust him completely. Donnelly’s continues to provide us with five-star service for our plumbing and HVAC needs. We continue to be very pleased with the service provided to us. ************************* January 18, 2025 My wife and I noticed the air coming out of our heating ducts was cool so we called the office Saturday morning. With a cold snap approaching we wanted to be sure our equipment was working. Natajia (I think I got the spelling of her name right) took the call and although only two technicians were on duty on Saturday, managed to get us on the list for that afternoon. She was really great. Justin Cooper came out, quickly diagnosed the issue (it was not a major one) and took care of the problem in about 15 minutes. We were very thankful and appreciative. Justin was very knowledgable, explaining in detail to my wife and me the problem and how he fixed it for us. The heat was back on with no further issues. We have had a service contract with Donnelly's for many years and we have recommended Donnelly's to our friends and colleagues without reservation. September 17, 2024 Domingo Clendaniel serviced our heating system to get the house ready for the winter and once again, we could not be more pleased with the services he provided. We continue to be impressed with the services Donnelly's provides us for our HVAC needs. This is a great company! ******************************************************* July 8, 2024: Tom Gardner performed our annual plumbing check up and once again, we could not be more pleased with the service he provided. Professional, courteous, knowledgeable, and so trustworthy. My wife and I continue to be impressed with the service Donnelly's provides us for our HVAC and plumbing needs. We completely trust that any work recommended to be done as preventative maintenance actually needs to be performed. The quality of the services provided continues to be top notch, and we would recommend Donnelly's to our friends and colleagues without reservation.

Eladio and Evan did a excellent job. They explained everything about me new heater and humidifier they installed. They cleaned up very nice when they were done. I enjoy working with you.

Excellent fast work. Very reasonably priced. Very courteous. Derrik did a great job. Great work!

Donnelly’s Plumbing was excellent. I had A leaking water softener. Tom Gardner responded quickly and was prompt and on time. Nice not having to wait a full day for an 8AM - 5PM appointment and have it canceled. Tom check out and explained the issue. We had to replace the softener and Tom set it up. Within a couple of days they had the parts and set up the time to install. Tom called and was here right on time. Work was done very efficiently and very clean! Look, nothing is cheap. But it is worse to have to pay a lot and get bad service or work. I was totally impressed with Donnelly and Tom Gardner! 10/29/2025 Calib Bradbury replaced a Kitchen Faucet and water valve for the hot water supply line which burst. Donnelly responded quickly to resolve this problem. Calib provided a number of solutions and prices we were very pleased with his response, service and efficiency!

Tony did great job.He was helpful in explaing was going on Frank&Georgia

Called Donnelly to check our 20yr old furnace that stopped running; they sent someone out that day. After a very detailed analysis of our existing units, we decided to replace our 5 gas furnaces. Donnelly scheduled us for the next day and completed the job same day! Everyone from Donnelly was extremely friendly and professional. They ensured that all work areas were left clean and swept. Would highly recommend!

Those people take their customer service people from the bottom of the barrel & rather combative. We've been with them for 3 years and EVERY time you try to get them on YOUR schedule forget about it. The ONLY reason we stay with them is that we unfortunately used them to replace our HVAC unit and the warranty runs to their company and usually their personnel who finally show up are skilled and courteous.

Great service, Joe Fletcher is professional and did a great job

Caleb was efficient and very pleasant.

Tom is the best out there. Always finds out what the problem is fixes it right the first time.

Great, fast, thorough diagnosis of issue! They came within 24 hours! Service person was courteous, friendly and explained everything to us. HIGHLY recommend them!!

Shane was very professional. He explained in detail what he was going to do. When he was finished he showed me what he did. Everything looked good and well done. Im happy with the results.

I was very pleased with Nick’s work. But, also with his explaining every detail of what he was going to do as well as some other important plumbing tips.

Met my expectations. Dylan was very competent and polite.

Rob was awesome! Great guest service skills, efficient and a true professional. We will be requesting him on all of our future HVAC system needs/R&M!

Joe was quite good and thorough. He was able to shut off the water and install the new pressure release valve so we didn't have to rely on the unreliable water company tech who didn't show a couple of days ago. Joe also trouble shot a persistent pressure problem with my kitchen faucet. Checked a couple of potential sources in the faucet with no answer yet. Will return to check a valve source. Have confidence in Joe and look forward to his return, answer, and fix. .

Robert was great! Went above and beyond.

Kevin is an absolute professional. Told us everything he checked for and let us know if we needed anything else. Great service.

Brandon quickly diagnosed the issue with our furnace and solved the problem saving us from a much more costly repair. He was very knowledgeable and professional. Thank you for the high quality service!

I wanted to edit and update my review for Donnelly's. I have been using them approaching 5 years now and I am extremely happy and satisfied with their service to my homes HVAC and plumbing needs. All the HVAC Technicians and Plumbers have been very nice and professional in their visits and service to my home. They always explain clearly what they are doing and what services are recommended when doing their inspections or repairs. They are always respectful and neat when working in or outside my home. I am also excited about their new Electrical Division and will certainly use them for this service as well for my home. I also want to give recognition to all the support staff (Representatives who answer the calls and the dispatchers) I am very appreciative of your work and professionalism. Thank you Donnelly's for helping in keeping my homes HVAC, Plumbing and Electrical systems working and running great!!!

Eladio was great! Showed up on time, very professional and courteous.

John was very helpful in evaluating our furnace as part of normal checkup. The result of needing a new one based on age and some challenges we’re currently having, wasn’t welcomed news, but was the reality that we need to begin thinking about replacement.

Called with plumbing backup in my lawn clean out. Came right out. Cleared the problem and back tomorrow to check line with camera. Back next morning with camera found root of the blockage in my sewer line. Identified precise location. Excavated to point of blockage and cut pipe section to remove blockage and pieced in the repair. Treated this as an emergency and prioritized it. All employees were skilled and very contentious. Pleased with the experience.

James was punctual, efficient, and most friendly. We highly recommend Donnelly!

Brandon did a great job. He was professional and very thorough. I am very please with his work.

Tom was good. But the stopper in the sink is crooked. Is there a way to straighten it? JDG

Caleb did an excellent job figuring out the cause for our Flushmate leak, got the part and installed less then 24 hours. Great turn around! Nice job Caleb, thank you.

Joseph is a real professional. He was very thorough with the information and offered me a good deal that was quick and easy. I would highly recommend using Donnelly’s for your HVAC needs. Additionally the install team of Jayson, Dave M and Dave W did an outsbading job. They were in time, communicated well and completed the job in a timely fashion. They left the place clean and I was completely satisfied with their work. Great job.

Great service, technicians are always professional and prompt

Everything went good Khalij was very nice and professional,he explained everything to me both times he came,he did a wonderful job and my heat is working great,thank you Khalij and thank you Donnelly’s Plumbing, I will highly recommend to family and friends.Thank you 😊

I don’t usually review, but this was really good. My plumber was Shane and he was great. Honest, showed me options, was very friendly and did the work fast and well. Will ask for him again.
