Venmar

The Venmar brand started as a pioneer in commercial air-to-air energy recovery ventilation. Formed in 1980 under the name Conservation Energy Systems, the company started as a Heat Recovery Ventilator (HRV) manufacturer before expanding its scope of products, first to light commercial in the late 1980s and then to the applied market in 1994. Over the years, Venmar brand equipment became a top choice for creating quiet, comfortable, and healthy indoor environments across North America.

In 1997 the Venmar brand expanded the energy recovery system and dedicated outdoor system product offerings of Nortek Air Solutions when it joined Nortek's family of brands.
