Why we are Different

Since 1948 Therma-Tech Engineering / A R Lintern Division has been a world class manufacturer of high quality HVAC Systems for the specialty transportation industry.  As a market leader in climate control systems, we have nearly 65 years of experience meeting our customers' needs.  With a vertically integrated manufacturing facility in Metropolitan Detroit, we have the resources to meet your Original Equipment (OE) and service demands.  Our custom approach to designing "what you need" versus a catalog solution is what sets us apart.

Our roots are in the school bus industry.  We provided the very first commercially available heaters to help keep our school children warm during the cold winter months.  Our organization then started to add additional specialty vehicles and markets to our growing list of customers.  In the last decade, we added military vehicles to our ever expanding list.  Most recently, we have developed all electric systems for the next generation of specialty vehicles.  We will continue to develop as technologies advance while supporting our long legacy of products.
