Welcome to Colvent Inc.

Colvent Inc (Columbia Ventilation) was founded by Stephan Sawch, Sr. in 1924 as a sheet metal and ventilating company, with a sheet metal production shop located in Long Island City. We remained a family owned company for 82 years. In 1956 we were incorporated by Walter Sawch, Sr. In addition, we signed with local 28 (Sheet Metal) and local 638 (HVAC-REF and pipe fitting). Today we have been specializing in HVAC-REF service contracting for over 60 years.

With offices located in Rockefeller Center, Colvent was instrumental in the modernization of infrastructures in the Rockefeller Center Complex. We are also an integral part of the retrofit project for the Time Life/Warner communications Building in which we installed chillers, water risers, air handlers, duct systems and a complete fire protection system for several floors in respective locations
