December 2019: We've moved! We're now at 1600 Industrial Road, unit C5, Cambridge. It is a newer facility with better access for our visitors.
February 2019: Make Up Air units now use the Vortex iStat6 control to allow field programmable fan speeds. Up to 3 different speeds (high, medium and low) are available.
January 2019: Zone Comfort air handlers have been re-designed. The damper box has been removed. Dampers are now installed and wired in the field. This will allow for more installation flexibility and reduce cabinet costs.
