What Our Customers Say

I have to give Dempsey energy five stars. The crew showed up on time and worked quickly to install a new furnace and heating system. Everyone was polite and professional and cleaned up after themselves. The job was done extremely well, at a very fair price. I would definitely recommend.
MIKE T.
I called Dempsey Energy because my furnace was not working. Matt came in and fixed my issue. He explained every step of the process. He was a pleasure to work with. I would absolutely recommend Dempsey Energy for your heating needs.
STEPHANIE B.
Charles from Dempsey Energy came to my house because I needed my heating fixed. He was very professional and diagnosed my problem. He was up front showing me three different options with prices. I really liked that because price was a concern of mine. Thank you Dempsey Energy for sending such a gentleman like Charles.
