Adams Manufacturing makes gas and oil furnaces for home and commercial purposes. These furnaces can be adapted for use as air conditioning units for central air. Adams is a privately owned company located in Cleveland, Ohio. Adams was founded in 1945 by Sidney Schonberger and remains a family-owned business. Initially the company only produced gas conversion burners, but began to develop new products and acquisitions in 1964.
In 1984, Adams purchased Humidaire and now manufactures a line of humidifiers still under the Humidaire name. In 1986, Adams purchased INTERburner assets from Sloan Valve Company. It acquired Magic Chef’s gas-fired heater business in 1988 and this led to an expansion of their production facilities. This allowed Adams to accommodate the newly purchased Dornback Furnace and Foundry Company. Adams went on to add the Uni-Pak low profile gas heaters to their acquisitions as well as the Sunheat low and high-intensity infrared heaters.
Adams was awarded a grant in 2003 from the National Oil Research Alliance to develop a high-efficiency oil-fired furnace. Adams now manufactures a condensing oil-fired unit heater with efficiencies as high as 99 percent.
