Heat Recovery and Energy Recovery Ventilation Systems
Heat recovery ventilation (HRV) and energy recovery ventilation (ERV) systems qualify for a tax credit. They provide balanced ventilation for homes on a continuous (or semi-continuous) basis without the energy loss associated with other ventilation strategies.
Typically, a trained heating, ventilating and air conditioning technician designs and installs these systems. Both typically collect stale air from kitchens and bathrooms and exhaust it outside. At the same time, fresh outdoor air is filtered, warmed by heat transferred from exhaust air, then delivered to bedrooms or main living areas. 
Energy recovery systems offer an additional benefit: They transfer moisture between incoming and outgoing air flows to help maintain healthy humidity levels indoors.
