Donnelly Inc

We worked with Tom in November 2025 for a full HVAC installation and it was a great experience. Tom and his entire staff are friendly, professional and provide expert service. The job was performed with high quality, on time and at competitive prices. I would highly recommend Donnelly Heating and AC!

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

This was a positive experience. We have been customers of Donnelly for over 8 years. They replaced our HVAC system and 75gal Hot Water heater. Technicians were skilled and did a great job and maintained a clean work area. I am particularly supportive of local family businesses and the pride that is represented in the delivery of quality work and the importance of teaching the next generation of tradesmen. Finally, they also provided guidance on rebates from the utility company as well as tax credits from the federal government on the new system. Nice work!

I would give 0 stars if I could. The older woman on the phone is extremely rude and condescending. I believe her name was Karen. My in laws were treated with such disrespect on the phone, I could hear her tone from where I was sitting. Keep in mind my in laws are well into their 80’s. To treat the elderly that way is disturbing. They claim to be a family business but the way they treat their customers - the people who keep them in business is concerning. I will be sure to tell everyone I know at church, my daughter’s school, and any one who asks to never use Donnelly heating and ac in West Chester.
