    The guys did an amazing job, maintained professionalism, and showed respect for me, the dog, and the house. They kept the work areas clean and laid out drop clothes to keep the rest of the house clean as well.

    April 2024 - I proactively replaced my furnace and A/C today, Jake and Jayson were wonderful, so quiet while doing their installation while I worked from home. They explained and showed me all the new equipment, walked me through the new thermostat and set my app up for me. They will file all my warranties and mail me the completed paperwork. I continue to be impressed with all of Donnelly’s employees and really appreciate how personable and knowledgeable they are.

    Feb 2023- Donnelly’s was fantastic again in an emergency situation. My hot water heater sprung a leak overnight and Donnellys came out and replace the equipment in the morning . I asked them to check the sump pump as I hadn’t heard it run in a while and the motor was gone, they replace that as well. Joe was great, courteous, efficient and knowledgeable. Happy they are my service provider for HVAC and plumbing!

    April 2022- Donnelly's has been a great service provider for my Hvac/heating and plumbing needs. All tech's are courteous and timely and provide a good overview of the service they provided. I really like that Donnelly's has already scheduled my annual plumbing and heating checkup for later in 2021, one less thing for me to remember to do and it's on my calendar!
