Thermal Zone is a brand of air conditioners, furnaces and heat pumps for residential and commercial applications. The Thermal Zone brand is trademarked by United Refrigeration, Inc, headquartered in Wilkes Barre, PA. United Refrigeration is a private company.

Corporate History

United Refrigeration Inc. is a heating and cooling product distributor with nearly 300 locations in North America. The Thermal Zone brand dates back to 1997, although United Refrigeration itself was founded in 1947.

Thermal Zone products are manufactured by Rheem.

Product Lines

Thermal Zone air conditioners range in efficiency from 13 SEER single-stage models to 16 SEER single- and two-stage models. The company calls its TZAB cooling system the most environmentally friendly air conditioner in North America since it uses R407C refrigerant, which reportedly has less of an impact on global warming than the more commonly used R410A.

Gas furnace efficiencies range from 80 percent up to 96 percent AFUE for the company’s modulating equipment. The furnaces are available with standard fan motors, ECM or programmable ECM fan motors and come in a range of configurations.

The company also offers two heat pumps for new and one for replacement applications. Features include on-demand defrost controls and easy accessibility for maintenance.
