"The maintenance service was very easy to schedule. The service tech was punctual, professional and very thorough. We had them provide a quote on a subsequent repair; however, we went with a different provider due to price/availability."

"Great job with AC repair!"

"This company was excellent all the way around. The staff member who contacted me was very nice and helpful. They were able to come out the same day (I did not have heat). They sent me a text message with a picture of the technician which I thought was an excellent feature. The technician, Jeff, was very nice and extremely knowledgeable. I would definitely hire them again because the work was top quality and the cost was fair and reasonable."

"Robert did a great job in checking out my furnace that wasn't operating and provided me with the next steps I needed to take with the gas company. I can't say enough good things about Robert. He was so extremely helpful and informative. I'm a delighted customer and am glad I have Dunn for my heating and cooling needs."

"Hosack Plumbing quoted me a price and repaired the issue within 4 hours of my call. I would definitely use them again. these folks are GREAT !!! 10 Stars"

"I had an older heat pump about 18 years old that wasn't working like it should. I called ComfortWorks and Matt came out and determined that the problem was in the condenser coil above my furnace. He said that there might be a problem to locate that old of a coil to replace but he would try to find one, He said if it were him he would replace the heatpump because of it's age and if I fixed, it if he could find a coil, I could be spending money and have more issues pop up because of the age. I thought about it and because he gave me a good price for replacement it made sense to get a new more efficient heatpump. Very honest and no pressure to do anything I didn't want to. He just gave me advice so I could make an intelligent choice."
