    Our experience was very good. Stanley arrived on time. The unit was installed without a problem. He highlighted the necessary items for me like the filter and drain. Cleanup was done to our satisfaction.

    Timely. Robert, technician, was polite, didn't mind questions, and was quite thorough in explaining. Liked the 45 mins warning on estimated time of arrival

    Travis was excellent for our gas line rerouting and deserves 5 stars. Would definitely call on him again. Only gave 4 stars because of some scheduling mix ups with the office staff. Price was reasonable.

    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!
