Donnelly Heating & Air Conditioning Inc

Donnelly was very helpful through each step of my new boiler installation. Tom Donnelly was always willing to take time to explain things to me. He never rushed me into a decision or pushed to make a sale, but he took time to understand my needs. His team did a great job with the installation, and we have experienced no follow up issues in the 3 weeks since installation.

We needed to have our heat pump system replaced. Tom, the owner, came out on time and very professional. He listened to our needs intently and presented his best solution. No high pressure, no up sale. I feel he was sincerely searching for the best solution from customer's point of view. The proposal was sent on time with enough information. The crew was working hard to get the system installed. The place was clean after the replacement. We had invited a few bids and Donnelly was one of the most affordable. Yes, I'd recommend Donnelly Heating & Air Conditioning to my friends.

We switched to Donnelly Heating & Air Conditioning Inc because we needed a new Heat Pump System installed. After receiving several proposals from both large and smaller local companies we selected Donnelly. Tom came out for a presale review of our system. He was professional, on time, knowledgeable, asked the right questions so he could prepare a proposal that met our needs and situation. No high pressure, no upselling, using his experience to recommend the correct Heat Pump System at a reasonable price. He addressed all concerns and questions we had with the correct solutions.

The installation crew was on time, very professional, knowledgeable, and experienced. The correct installation is as important as the system you select. Otherwise, you could have issues down the road or not happy with the installation. They were on time, professional, explained all they did and how to get the most efficiency from our new system, took the time to explain the system and were careful to keep everything clean and neat. We also installed a Fresh Air Anti-Virus/Mold/Odor and Dust Ozone Free Purifier which other companies didn’t even offer.

You will be very happy if you need a small repair or an entire new heating and cooling system. We highly recommend Donnelly Heating & Air Conditioning for all your heating and cooling needs.

Tom was responsive, reliable and professional. We had our oil boiler converted to propane and his team was great. I'd highly recommend this group for any hvac needs. Thanks again Tom

This company was great. They replace my HAVC system and water heater. Quick, clean and responsive. Great job would definitely contract with and recommend Donnelly. We ran into an unforeseen duct issue and they dropped of a mobile AC unit to make sure my family was comfortable for the evening.

They did a great job. On time, on budget. Installed a new AC system. I am very pleased and would highly recommend them.

Called Donnelly for an estimate to replace our HVAC system due to our AC going out in the middle of a heatwave. Tom (the owner) came out and provided a quote and charged our AC free of charge due to us having a bedridden senior in the house. Toms quote was the best of 4 that we had and we greatly appreciated his efforts in helping us with no obligation, it said a lot about him as a person and how he operates his business. He had his team out as promised and did a great job replacing our system. We have our all of our maintenance done by Donnelly and have been very satisfied for over 8 years now. His guys are professional, respectful and nice to deal with. We highly recommend Donnelly!

Really enjoyed that I had an emergency during a heatwave, waited about 5 minutes to get to their emergency answering service.... only to find out they don't have emergency services. Just somebody they pay to say "so sorry, we'll leave them a msg for Monday". I went with a different local company who provided amazing customer service, to include weekend texts from the owner. Will not be using Donnelly again moving fwd

This was my second experience with Donnelly H&A/C.....hot water heater install last year and a brand new HVAC system this year. Professional, responsive and showed up when they said they would! Highly recommend.

We interviewed 4 HVAC companies and Donnelly Heating & Air Conditioning was by far the most professional. Tom Donnelly is very friendly and very easy to speak with. He answered all our questions in terms that the average consumer could easily understand. Donnelly’s prices were also the best, but our decision had as much to do with the good feelings we had about the company. Our friends referred us to Donnelly as they and other family members used them in the past.
Installation went smoothly, their very clean and the installers (ask for Lou) are friendly and knowledgeable.
I would strongly suggest calling them if you have any interest in a new heater or air conditioner. The time spent will be well worth it.
