“I’m so glad I chose this company to check and clean my furnace. I was quite impressed with the communication and was sent a photo of my tech before his arrival. He was friendly, knowledgeable, and efficient, and explained everything to me about my furnace. I highly recommend Donnelly’s.”

Extremely Happy with our technician Joe. Knowledgeable.. very polite.. and knew what he was doing. Donnellys is very good. If any negative from me it would be that they are expensive.. but quick to respond

We think that this company is taking advantage of their customers. For the 2nd time in 2 years, briefly after a maintenance job, the system shut down and they "offer" a replacement. We did replace a unit 2 years ago and had additional problem because of ...a bad installation. We just cancelled our service after the most recent event.Read More...

I have been using Donnelly's for HVAC maintenance for several years and also had them install a new heating/ac system recently. Their work, technicians, customer service, sales and management are 2nd to none. They are good people and I would recommend ...them to anyone looking for honest, fair and timely service.Read More...
