Tjernlund Products inception dates back to 1938 when Emil Tjernlund and his son Robert started designing and producing oil fired forced air furnaces. From this beginning their product offering evolved to gas fired furnaces and habit  packaged roof top heating & cooling equipment. In the mid 1950's our automobile Draft Inducers were developed to get rid of draft problems associated with short stacks on roof top units. Other folks within the heating industry shortly saw the advantages of our draft inducers and wholesale distribution of the Auto Draft Inducers began in 1957.     Tjernlund Products was spun off as a separate business in 1973.

The original manufacturing center had 10,000 ft2 and 12 employees. Since that time we have expanded our center to 75,000 ft2 and have grown to more than 50 employees. Our engineering and production departments feature the most recent technology in 3D CAD design and CNC turret presses and wheels.   Tjernlund Products remains owned and managed by Emil's grandsons, Robert and Tom and Emil's great grandson Bob. Within four decades our mission has been to provide quality engineered and fabricated products that solve exhaust, ventilation and heating/cooling problems. Paramount to our success is providing the technical support necessary to ensure our goods are easy to select and install. We're devoted to serving your distinctive exhaust and ventilation requirements.
