Who is Boyertown?

In 1939, Frank Wilhelm would begin his journey into the heating industry. He utilized his field experience and his passion to design an oil fired warm air furnace that would set a standard to which all others would be measured. In doing so, he designed and manufactured the furnace known today in the industry as the “HALLMARK”. 

The Hallmark Furnace entered the market in 1939, in 1981, Boyertown Furnace Company proudly took over the manufacturing of the Hallmark Furnace and by 1992, and Boyertown Furnace doubled the size of its original building.

Boyertown Furnace has added two new members to its family. The “ REGAL” for residential and the “COX” for commercial applications, giving Boyertown Furnace the most complete line of oil furnaces in the industry, allowing firing from 65,000 BTUs to 400,000 BTUs.
