Make-Up Air and Exhaust systems

Residential Make-Up Air:
“Make-up air is required in a home when exhaust systems, such as kitchen range hoods or bathroom fans, remove large volumes of air. Supplying fresh air prevents negative pressure, ensures proper ventilation, and protects your heating system from backdrafting.

Commercial Make-Up Air:
In commercial spaces, make-up air is needed whenever exhaust systems, like commercial kitchens or large ventilation setups, expel significant amounts of air. It replaces the exhausted air with fresh air to maintain indoor air quality, proper system performance, and compliance with building codes.
