    It's a frightening experience when a Heating/Cooling system needs to be replaced.

    Toilets are flushing. Shower is flowing. Fortunately Donnelly Plumbing and HVAC have knowledge, experienced and compassionate employees. Thank you for your expeditious service. Toilet replaced today, 07/07/25

    Jeremy came to our house to provide a diagnostic. He was extremely knowledgeable and explained several issues to my wife and I, who are not well-versed in plumbing. We look forward to working with Jeremy on our plumbing projects, confident he will do great work!

    Very pleased with service from Donnelly’s last week. Nafeese Taylor was friendly, professional and knowledgeable. AC systems tuned up and ready for summer. We’re in good hands.

    We had a very frustrating situation with low voltage coming into our home. After a week of little help from PECO, we had Donnelly’s come out to check the interior electric of our home.

    Brent, Sam, and Roger went above and beyond to help diagnose the problem, work with PECO to mend corroded wires, and ultimately replace our faulty meter box. I believe they are 100% the reason we were able to get back into our house as soon as we did. We will be using this company for any electrical jobs we have in the future.

    James G was great! Quickly assessed and diagnosed our AC units issues. He worked through a rainstorm to get it done for us on the spot and he was even great with our dog! 10/10 experience.
