Tjernlund Products inception dates back to 1938 when Emil Tjernlund and his son Robert started designing and manufacturing oil fired forced air furnaces.

Tjernlund Products is still owned and managed by Emil’s grandsons, Robert and Tom and Emil’s great grandson Bob. Over four generations our mission has been to provide quality engineered and manufactured products that solve exhaust, ventilation and heating/cooling problems. Paramount to our success is providing the technical support necessary so that our products are easy to select and install. We are dedicated to serving your special exhaust and ventilation needs.
