## Description

Tjernlund products inception dates back to 1938 when emil Tjernlund and his son Robert started designing and manufacturing oil fired forced air furnaces. From this start their product offering evolved into gas fired furnaces and custom packaged roof top heating & cooling equipment. In the mid 1950's our auto draft inducers were developed to eliminate draft problems associated with short stacks on roof top units. Other people within the heating industry soon saw the advantages of our draft inducers and wholesale distribution of the auto draft inducers began in 1957.
