About Us


100 years of experience

The more you learn about our manufacturing process, the more you'll see that no other heating and cooling manufacturer compares to Intertherm's product quality.

Otto and Nick

While other companies test products at random, we use 100% computer-automated testing on every Intertherm product to eliminate human error in the final analysis of product quality.

Demand Flow Technology

We are the only heating and cooling manufacturer to be certified in Demand Flow Technology.

DFT is a quality-control process in the manufacturing plants:

DFT is not a one-way assembly line. When contractors send us product suggestions, concerns or attaboys, we post them on the assembly line, at the exact place where that component is added to the equipment, for every worker to see. That's how your feedback goes into every product we make.

Make the easy choice

With more than 90 years of experience in the manufactured housing industry, it is easy to see why most new manufactured homes are built with Intertherm heating systems, and when applicable, are equipped with Intertherm cooling systems, too.
