Extremely Trustworthy and Reliable
We have used Farnen & Dermer for more than 25 years. We have always found them to be extremely trustworthy and reliable, the quality of their services is unmatched in the market.
Updating our previous review. Recently had hot water heater and heating unit installed. As always prompt, professional service with expert work. On a Friday afternoon they started a big job and stayed until 10:30 pm to make sure the job was done right. Eric L. was great.

Immediate Service
They came through once again! Our water heater got a crack and water was everywhere. I called, and they had someone at the house within 20 minutes. I was expecting them to turn everything off then make an appointment for repair for another day, but nope! Eric made a call and began the work right away. By the time dinner was on the table, service was complete. Thoroughly satisfied and extremely grateful for their immediate service!

Technicians were very knowledgeable.
Technicians Eric, Michael, and Devan were very knowledgeable, courteous, and worked very well as a team. Owner Ed Dermer was very helpful in explaining the HVAC systems, and Zach Dermer was very supportive with all the logistics.

Competent, Courteous, Professional Team
Dear Mr. Dermer— You can really be proud of the company you and your family have built. What is more, you have kept it functioning effectively for over a century, I think. And of course, it is much easier to start an enterprise than it is to sustain it durably over a lengthy period of time. I think I know part of your secret: the quality of your team. On this project, I have met James, Glenn, Caleb, RJ, and Shaun and without exception, they were all competent, courteous, professional, and friendly. I also greatly appreciate the promptness; it was mighty cold around here and you got our heat up and running far more quickly than I expected. And getting one of your guys back here first thing this morning was exceptional service. In my view, you deserve your reputation and your success. I am a big exponent of family-run businesses and I thank you for giving me another model to mention—Farnen and Dermer. Is the history of the firm written up anywhere? Please convey my appreciation to the members of the team who took care of our problem. They were a pleasure to have in our home. Sincerely, Daniel Lapin

Fast and Efficient Service
Losing heat during the night when it’s really cold is no fun! Called at 11:50 a.m. and someone came at 1 p.m. Fast, efficient, and explained everything clearly. Charlie was great!! It's now 3:30 p.m. and the house is getting back to normal.
