Get to know Adam Derr, a local solution-finder you can depend on year-round.

“I grew up in the heating and cooling industry as part of a family-owned business. and a family name that earned a reputation as one of the most knowledgeable and trusted HVAC sales and service providers in America’s heartland. The Derr name was synonymous with dependability and innovation, whether installing a heat pump in a small, single family dwelling or consulting on a large, corporate facility.

I founded Derr Heating here in Kitsap County to bring a new level of accountability to the area. Now you can appreciate the cost-benefit of product efficiency with the heating and cooling systems you choose for your home or business.

A New Standard  for The Great Indoors

Beginning in 2023, new standards in energy efficiency are reshaping the landscape.

Derr is committed to an even higher standard.

Put simply, you can’t choose the right HVAC system if you don’t have a choice. Derr specializes in customizing the ideal solution from a wide-array of options designed to meet your individual needs and preferences.

At Derr, our good name and reputation go on the line with every HVAC project, large or small. Because we know that it’s your good name we stand behind.”
