Oil and Gas Furnaces require combustion air for proper and complete burning of fuel. Combustion Air is drawn into Oil and Gas Furnaces from the surrounding space. There must be a constant air exchange for energy efficient combustion. Combustion Air Intake Units bring outside air directly to the furnace for combustion. Fresh Air Intake Units also bring in outside air acting as an air exchanger for the whole house - replacing combustion air. Heat Recovery Ventilators - HRV - vent stale air out of the building while bringing fresh air in. The vented air passes through an energy exchanger which captures the heat or cool energy. The entering air passes through the same energy exchanger recovering  the captured energy.
