Hart & Cooley

Hart & Cooley: Over a Century of HVAC Innovation

Hart & Cooley has been a cornerstone of the HVAC industry since 1901, when founders Howard Hart and Norman Cooley established their manufacturing company in New Britain, Connecticut. That first venture made history as the first in the nation to produce warm-air registers from stamped steel — a sign of the engineering ambition that would define the brand for generations to come. Today, headquartered in Grand Rapids, Michigan, Hart & Cooley stands as one of the most recognized and trusted names in air distribution and venting solutions.

What Hart & Cooley Makes

Hart & Cooley specializes in a comprehensive lineup of residential and commercial HVAC products. Their catalog spans grilles, registers, and diffusers for precise airflow control; flexible and rigid duct system components; Type-B gas vent systems for gas-fired appliances; chimney systems and chimney liners; roof flashings; and access doors. Whether the application is a new home build, a commercial retrofit, or an industrial ventilation project, Hart & Cooley's product range is engineered to cover it.

The brand is part of the Duravent Group, a climate technology portfolio that unifies more than a dozen established HVAC brands. This broader family of brands — including Selkirk, AmeriVent, AmeriFlow, AMPCO, Heatfab, and Milcor — gives Hart & Cooley access to extensive manufacturing and engineering resources, with facilities across the United States, Canada, and Mexico.
