Custom Curb Adapters

Curb adapters provide an efficient interface between an existing HVAC rooftop unit and a new replacement unit that feeds the heating and air conditioning to and from the building. The rooftop ports are built into a raised external assembly called a curb. Many of these rooftop HVAC curbs were originally set into the roof to accommodate old HVAC units that are either no longer in production or no longer the best choice for the building’s current needs.
