Hart & Cooley recently opened this test lab at the company’s Michigan headquarters.

HVAC accessories manufacturer Hart & Cooley Inc. has completed work on a 1,300-square-foot test lab at its Grand Rapids, Mich., headquarters. 

The three-story addition will be the site of testing to ensure duct, vent and chimney products meet industry standards, the company said. 

The lab incorporates the use of Hart & Cooley’s own Milcor roof hatch and a damper and exhaust fan from PennBarry, a sister company.
