I recently had Donnelly’s service my 6-year-old HVAC unit in my older home, and I couldn’t be happier. Matthew, the technician, was incredibly knowledgeable and took the time to explain everything in detail, ensuring I understood the process. He quoted me exactly what I expected for the necessary work, and the pricing was very reasonable. The service was top-notch, and I was so impressed that I signed up for a service contract with Donnelly’s. Highly recommend!

Great service job by Matt today. One of the 2 units was not in an easy place to access, but he had no complaints doing the work necessary for the maintenance checks. He was very helpful in getting the outdoor coils cleaned on the outside units as well. Highly recommend!

We always call Donnelly’s for all our plumbing needs. And a special thanks to Joe M for his first rate service! He even had time to pose with Donnelly’s biggest fan, grandson James!
