This proves difficult to determine the specific style used and subsequently interpret the date of manufacture. Unfortunately we have not encountered any data plates which indicate specifically the OEM or "made by." name. Similarly, other Heat Controller brands utilize Rheem, ICP, Goodman, Addison, and Climate Master style serial numbers. For example, most recent Comfort-Aire systems utilize a Nordyne style serial number, indicating the units to have been manufactured by Nordyne for Heat Controller private label. As such, the serial numbers encountered will be similar to the Original Equipment Manufacturer (OEM) styles. In fact, an older version of the now defunct Heat Controller website indicated manufacturing facilities for Comfort-Aire brand equipment were located in Texas, Florida, New York, Tennessee, Arkansas, and Toronto, all of which are known headquarters or facilities for other brand manufacturers. To our knowledge and research, Heat Controller is no longer an original equipment manufacturer, but rather distributes private-label equipment under Heat Controller brand names made by other manufacturers. The units under the Heat Controller brand names were actually manufactured by a variety of entities including but not limited to: Climate Master, Goodman, Rheem, ICP, and Nordyne. Heat Controller is/was a wholesale distributor of HVAC equipment under their own private brand lines of primarily Comfort-Aire and Century. Important Brand Notes: Comfort-Aire is an HVAC private label brand of Heat Controller, Inc. Subsidiaries or other related brands: Heat Controller (H.C.I.) | Century | Comfort-Aire | Comfort-Aire by Aitons | Parent Company: MARS (Motors and Armatures, Inc) - merged with Heat Controller, Inc.
