Who makes ICP air conditioning units?

ICP air conditioning units are made by International Comfort Products LLC, which is itself owned by Carrier Global Corporation. ICP is not a single air conditioner brand but rather the manufacturing company that produces a family of HVAC brands that share common platforms. ICP was formed from the consolidation of several historic HVAC companies including Heil, Arcoaire, and Comfortmaker, and was acquired by Carrier in 1999. Today, ICP operates large manufacturing facilities in Lewisburg, Tennessee, which is its main plant for residential gas furnaces, air conditioners, and heat pumps, and also has operations in other locations. ICP makes air conditioning units under the brand names Tempstar, Heil, Arcoaire, Keeprite, Comfortmaker, Day and Night, and Airquest. All of these brands are built on the same assembly lines using many identical core components such as Copeland scroll compressors, Micro-Channel coils, and Carrier-designed control boards, but with different badges, warranties, and distribution channels. So when you ask who makes ICP units, the answer is that ICP itself is the manufacturer, and ICP is owned by Carrier, meaning Carrier is the ultimate parent company. The nameplate on an ICP unit will say International Comfort Products LLC, Lewisburg, TN, a Carrier company.
