About Farnen & Dermer

Generations of Reliable Service

Farnen & Dermer has been proudly serving Owings Mills, Baltimore County, and the surrounding areas for 5 generations. Originally established in 1902 by Leon Dermer, our business got its start in the Pimlico area.

As a family-owned and operated business, Leon’s son Harold joined the business and then passed it along to his oldest son, Frank. Today, Frank’s sons, Jay and Ed run the business with the same tradition of excellence originated by their great grandfather. The newest generation of Dermers is now in the business, as Ed’s son Zach now helps runs the business with his father and uncle.

We truly believe that high-quality heating and cooling service starts with factory-trained technicians who are qualified. On top of that, our entire team will treat you with friendly and respectful customer service.
