Donnelly Heating & Air Conditioning

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.

Great diagnosis and execution. They even provided space heaters so we were warm while equipment was ordered and installed. A+ Service: Heating system installation

I had a great experience with this company. Everyone that I spoke with and interacted with were very friendly and helpful. When the work was being doing in my house all of the men were incredibly professional and respectful of my home. They cleaned up after themselves and explained the system to me before leaving.

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!

Great price and quality of work. Had 3 estimates for new HVAC system. Donnelly HVAC was the lowest cost by far. Tom the owner explained everything when I got the estimate. He did not give a hard sell and was very easy to work with. He responded quickly to my emails and phone calls. Installation was done on date as scheduled and finished on time in one day. Highly recommend this company.

My sister had an issue with her heating the first weekend it was cold. With no heat and kids in the house, we had to get it fixed asap. We called Donnelly and they had us scheduled for that afternoon. Lou came out and was very professional. He wore all the appropriate safety gear, went down to take a look at the heater, and even explained what was going on to my niece.

He fixed the heater and even recommended some items we might want to consider without being pushy or salesy. We really appreciate their professionalism and everything has been working great ever since. 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.

We had a new HVAC unit put in by Donnelly heating and air recently. It was a fantastic experience from start to finish. The techs were on time and professional, as well as quick! We have worked with other larger companies in the past, but never again. Nothing beats working with a family run business. They truly care about their customers. Thank you so much to Tom and his techs!

We have been clients of Donnelly for over 20 years. Their technicians are top notch professionals. Recently they installed new AC, heater and hot water heater in our home. The service was excellent and the total cost was very reasonable. We highly recommend Donnelly to all our friends and neighbors who need heating and AC services.

I am very pleased with Donnelly Heating. I contacted them 3 yrs ago for a broken oil heater but couldn't afford the replacement heater at the time. I contacted them again and 3yrs later was still treated as a valued customer. Mr Donnelly remembered me which highly impressed me. He and his staff are professional, friendly and courteous. The installer is very knowledgeable. I'm happy with my new Gas heater conversion. I would highly recommend Donnelly Heating.

Can't quite say enough but they are amazing! No haggling, they sent an installer to make sure the quote was accurate. They arrived on time and gave accurate times and plans, were incredibly professional and clean and the install was beautifully done with extra consideration for the space since we didn't have duct work and they had to run all of that through the house and took a lot of our storage space in the attic but they went the extra mile to run across the rafters to preserve our floor space. They were even considerate working around our dog to make sure she did slip in the drop cloths. I highly recommend them!

My wife and I cannot speak more highly of our experience with Donnelly Heating and Air Conditioning. Being first time home buyers and this being our first major home purchase it was very helpful to sit down with Tom during our initial consultation. He was able to fully walk us through what to expect and work within our budget. Lou and Dave performed the work at our home and I cannot speak enough to how thorough and professional they both were. Showed up on time, explained things step by step, came up with solutions that enabled the job to get done, cleaned up daily, and were done the work faster than anticipated. Donnelly Heating and AC will definitely be the company that we recommend to all of our friends and family!
