Coleman® is one of the core residential brands sold by York® International, the largest independent manufacturer of heating and air conditioning equipment. As part of a $4-billion company, Coleman provides its customers with all the benefits of a large corporation, such as a wide product range, extensive research and development, innovative manufacturing facilities, and national distribution, all while still giving their customers the undivided attention they deserve. Efficient, reliable heating and cooling solutions backed by courteous service with a smile makes Coleman products the smart choice for homeowners, dealers, and distributors looking to make a sound investment.

By 1958, the Coleman Company had entered the HVAC industry, designing units for mobile homes. The success of this endeavor led to a full-fledged entry into the HVAC industry. This move resulted in the acquisition of Red T Coil - a leading independent manufacturer of evaporator coils and fan coil units - in 1984.

In 1990, Beacon Capital Corporation negotiated the purchase of Coleman's heating and air conditioning division to create Evcon Industries. By 1996, Unitary Products of York International had acquired Evcon Industries and continued to market their products under the Coleman-Evcon name.

In 1999, realizing its outstanding brand recognition, Unitary Products Group decided to market products, solely under the Coleman® name - a name now known for rugged, reliable performance in the great outdoors and the great indoors.
