Very professional and courteous. Best price with the best quality of both products and services. I’d highly recommend Dempsey Energy to anyone.

Chris, the tech who came out, and the people at Dempsey have been amazing. They came out quickly and Chris took the time to explain everything to me and help calm my anxiety. When an additional problem popped up right before the 4th. Chris was there bright in early to make sure my A/C was working properly despite the holiday. This is definitely a number I will be saving for future issues.

Just had my furnace and air conditioner replaced. They were both 30+ years old. I was so impressed with the hard work that Tim put in to get my heat working after the old furnace died. He went above and beyond my expectations! He left the basement cleaner than when he arrived. It was a big job, and Tim did it with very little break time...not even sure he ate any meals while working 10 hr days. I was so grateful to have such a nice guy working here.

Dempsey Energy was GREAT! Although there are those who have posted negative reviews of Dempsey Energy, I was completely unable to get ANYONE ELSE to come for a furnace cleaning and checkup. Dempsey responded immediately, showed up EARLY, and did a superb job on my system. The technician was courteous, and left the area cleaner than when he arrived. The price was the same as I had paid someone else over 5 years ago. After the visit, I called their office for the receipt, and it arrived within a few minutes!

I am a former customer of Dempsey, and i have to say their oil service and service plan was wonderful. I'd like to thank them for treating me wonderfully over the two years I lived in a place with an oil tank. If I ever move into another place which has oil heat, you will be the first ones I call. THANK YOU!!!

We needed a new central air system (two condensers, two air handlers and two hydronic coils). Eric Dempsey came out and went over the different product lines, their pros and cons. He was informative and helped us make a decision (we went with Trane). They started the project shortly thereafter. Roy (chief technician) did a great job with the installation and Don (Project Manager) stayed on top of everything. The work was done professionally, the system was tested thoroughly and they cleaned up their work areas when they were finished. We are very confident that we selected the right firm for the job.
