We contacted Dennis last minute with a furnace problem in preparation for a cold weekend. Dennis was able to come out, after hours, to complete the repair the same day! He was professional, courteous and friendly. The repair was made quickly and reasonably priced. We will definitely be calling Dennis for all our future HVAC needs! Highly recommend him!

Just like another reviewer, we called Dennis at the last minute! Not only was he responsive, but he came out within a few hours and fixed something that I broke while trying to a repair. Professional, knowledgeable (he didn't mind answering all my questions) and fair! If you are in need of heating or AC help give Dennis a call, you wont regret it!
