My technician again was Farrell and this time he replaced my old furnace. He gave me reports along the way and gave me a tour at the end of all the features. I am very happy with Dunn.

Outstanding service! We had our regular maintenance visit to clean and service our HVAC unit at a house we recently moved into. The technician found and cleaned out a birds nest that was blocking the intake vent from outside, and then discovered a wiring issue from the original installation that needed to be redone to make the unit run more efficiently. And there was no additional charge for the work. All included in the maintenance plan. We have been using this company for the past three years at our previous house and I would highly recommend them!

Farrell, is fantastic and can be trusted. Today I left the door open for him, he did his work and reported back to me. This company is excellent. I recommend them.

Excellent customer service, always looks and explains what issue is and determines how he is going to resolve it. Goes the extra mile to ensure job is thoroughly and quickly done the right way the first time. I am left very satisfied with that l will have no problems after he leaves. Highly recommended.

We have so much confidence in Farrell in particular and JT Dunn in general We’ve had some unusual problems and Farrell really explains what is going on and then gets going on a solution.
