Our Products

total system design

Our principal products are vehicle heating, ventilating and air conditioning (HVAC) systems as well as individual components. Customer expectations have evolved in recent years, placing an increased emphasis on driver/passenger comfort and safety. Successful HVAC suppliers have had to re-assess their approach toward meeting these more sophisticated expectations. At Evans Tempcon, we call this Total System Design.

Working in partnership with our customers and suppliers, we design, test and manufacture complete HVAC systems, consisting of components specifically designed to meet or exceed the demands of the application. Through the efforts of our talented R & D staff, complete prototype systems can be developed and presented to our customers in record time; systems that meet quality and performance objectives while remaining competitively priced.

In recent years we have focused our new product development toward "hard to heat or cool" applications such as motor homes, step vans, transit busses, and agricultural equipment. Our achievements in solving the tough problems associated with these markets can be applied to meet your special needs.

Complementing our design expertise are manufacturing processes that assure high quality and on-time delivery, drawing on the talents of our experienced personnel as well as suppliers known for their own strong quality and performance standards. Our in-house capabilities include:

Sheet Metal Fabrication

Welding (Mig, Tig and Spot)

A/C hose Assembly


Heat Exchanger (Coil) Manufacturing



Meeting customer expectations demands a high degree of quality objectives.
