Heat Controller

About Heat Controller

Heat Controller has been a cornerstone name in the residential and commercial HVAC industry for well over a century. Founded with roots tracing back to the Wingert Furnace Co. in 1907, the company formally took shape in 1933 and spent decades building a reputation as a reliable source for heating, cooling, and dehumidification equipment. Today, Heat Controller operates as part of MARS (Motors and Armatures, Inc.), a family-owned and operated business that has served the HVACR industry since the mid-20th century, dramatically expanding the product reach and distribution capabilities that Heat Controller customers depend on.

A Legacy of Growth and Innovation

Over the decades, Heat Controller grew strategically through a series of key acquisitions. In 1975, the company acquired the venerable Century® brand, adding a full line of residential and light commercial products to its portfolio. In 1995, it brought on Addison Products — an innovator in split-system air conditioning — and in 2000 extended its North American footprint by acquiring Aiton’s Equipment of Canada. These moves cemented Heat Controller’s position as a true full-spectrum HVAC supplier, with products spanning everything from heating systems to sophisticated cooling components.

When MARS merged with Heat Controller in 2013, the combined entity gained the depth of an established motor and components distributor alongside Heat Controller’s well-developed equipment line. Today, the MARS Equipment Division — operating out of Heat Controller’s longtime home base in Jackson, Michigan — continues to deliver residential and commercial systems ranging from half-ton to 25-ton capacities under the Comfort-Aire and Century brand names.

HVAC Components You Can Count On

What sets Heat Controller apart from purely equipment-focused brands is the breadth of its component-level offerings. Technicians and DIYers alike turn to Heat Controller for the critical parts that keep climate control systems running at peak efficiency. The brand’s HVAC Control Modules are engineered to provide precise system management, enabling accurate temperature regulation and reliable communication between system components. For airflow, Heat Controller’s HVAC Blower Motors and HVAC Heater Fan Motors are built to deliver consistent, quiet performance in the demanding environment of a forced-air system.

On the cooling side, Heat Controller’s A/C Expansion Valves play a vital role in metering refrigerant flow into the evaporator coil — a function that directly impacts system efficiency and cooling capacity. Rounding out the cooling system lineup, the brand also offers A/C Condenser Fan Motors designed to maintain proper heat rejection at the outdoor unit, preventing high-pressure faults and premature compressor wear.
