Well, I for one am very pleased with Dempsey Energy and especially Tim our technician. He fixed our air conditioner quickly and at a reasonable price... and was super personable as well. I would definitely call them again... and ask for Tim!

William was on time, knowledgeable and courteous. In addition, William gave us top of the line service and also identified some other issues that we will need to deal with in the future. Top notch service! I highly recommend!

We had a great experience with Dempsey. Joe, Eric, Tim, Cris and their crew did an amazing job installing mini split heat pumps in our home. They went above and beyond to make sure we were happy with the outcome. Would highly recommend Dempsey for any HVAC or other energy related needs. Thanks Dempsey!

I just want to thank Dempsey Energy Co and their service person, Maryann O'Shea for providing prompt, professional and kind service this morning. The people at the office were professional (and kind) in helping to get the technician to the condo and Maryann was amazing and of course, very professional and thorough in evaluating the situation.
