[H2] A Century of Excellence in Specialty HVAC Applications

When it comes to heating and cooling for specialty residential HVAC applications, no one has been doing it longer than Intertherm.
Founded in 1919, Intertherm began its legacy of innovation in St. Louis, Missouri. The 1930s saw the introduction of the first heater specifically made for use in residential mobile homes. By the 1950s, we had produced an array of “firsts” in the market, and we didn’t stop there.
Today, our RightFit approach to matched equipment systems offers seamless integration and holistic operational efficiency to help homeowners, contractors, and distributors alike make the right choice, right from the start.

[H2] Designed With Your Space in Mind

The days of mixing mismatched equipment, and risking poor performance and increased costs, are over. Our heating and cooling products are engineered to work together seamlessly while delivering peak performance. With Intertherm, you get one brand, clear system matches, and the RightFit for your home from day one.

[H3] Manufactured Homes

After 100 years, no one understands factory-built homes like Intertherm. Our market-leading furnaces feature space-saving and aesthetically pleasing design. Get trusted, consistent performance and complete peace of mind knowing your home is equipped with the best in comfort technology for manufactured homes.

[H3] Modular Homes

Modular homes versus manufactured homes…yes, there’s a difference! Things like ductwork, insulation levels, and air distribution can vary significantly from manufactured or mobile homes. Our expertise in unique HVAC applications means Intertherm’s equipment solutions provide reliable, energy-efficient performance tailored to your modular home's specific needs.

[H3] Tiny Homes

Even the smallest spaces deserve big comfort. Our line of ductless equipment allows you to effectively regulate air temperature and circulation, giving you the year-round performance and comfort of a traditional HVAC system without sacrificing your smaller living space.

[H3] Single Room

For some applications, it’s necessary to divide a home into multiple HVAC “zones” for optimum heating or cooling. In these scenarios, our ductless products allow you to set individual rooms to the ideal temperature while offering flexibility for the room-by-room heating and cooling needs.

[H3] What RightFit Means for You

To us, efficiency means more than just energy savings. It’s about making sure our RightFit solutions deliver maximum holistic operational efficiency across energy, space, cost, installation and service, and product compatibility. Resulting in high-quality, versatile, and dependable HVAC systems that provide the RightMatch and RightFunction for almost any home type - all backed by the RightFoundation - right from the start.
