Fresh Air Supply System for HVAC

• To help replace air exhausted by fireplaces, pellet and wood stoves, bathroom fans, laundry dryers, range hood fans, central vacs, radon systems and other combustion and / or exhaust devices

• To improve Indoor Air Quality

• To increase fresh air changes

How It Works

The Make-Up Air System connects the HVAC system to the outside to allow controlled amounts of fresh air to enter the system when needed. The system automatically senses pressure changes and a need for air flow and opens to bring a precise, metered amount of fresh air into the air handler. Here the cold air is tempered as it mixes with warm air in the return duct. The air is filtered then heated and distributed through the home via the central duct system. When the need for air is fulfilled, the system closes to prevent further air infiltration. The system must be installed by a qualified heating and air conditioning professional and is adjustable for homes from 1000 to 4000 square feet. It does not require any electricity or maintenance.
