Mike and his assistant provided top tier service during the heating system installation. They are knowledgeable, professional, and pleasant! A special thanks to Zach as well for guiding us through the financing process with ease.

Farnen & Dermer was a pleasure to work with.
I called at 7:30 am with a minor crisis. 20 degrees out there, no heat in the house and a complicated set of medical appts to get to in the morning. The Farnen And Dermer team was excellent. They were able to send a technician right away. He diagnosed the problem, fixed the unit and explained everything clearly. The quick response and overall professional work is appreciated.
