The Carrier Heat Recovery Comfort Ventilators are designed to operate as an integral part of a total HVAC system while improving a homeowner's air quality. As the Comfort Ventilators exhaust stale indoor air to the outside through the recovery core, fresh air drawn from outside is warmed or cooled by the energy present in the exhaust air. Excess wintertime humidity is flushed from the house as are indoor contaminants by the HRV.
