The Janitrol brand was discontinued in 1992 when the Goodman Manufacturing Co. consolidated the line under the Goodman brand name. Many of the Janitrol units are still in operation, and parts are available from some dealers.
The PG series of Janitrol furnaces were low-efficiency, gas-fired units and featured AFUE ratings of up to 78 percent. The units were manufactured for rooftop installation. The Janitrol PGB home-use furnaces had an 80 to 82 percent steady-state efficiency rating, which classified them as mid-efficiency furnaces.
Goodman Manufacturing Co. purchased Janitrol in 1982 as its entryway into the HVAC market. Goodman is one of the leading HVAC brands in North America and caters to the large segment of the market that desires reliable and value-based indoor climate comfort. The company also owns the Amana premium-performance brand.
