VENTILATION SYSTEMS

Ventilation through a separate geo-thermal air exchange system brings tempered outside air into the house through underground pipes.  The outside air temperature is warmed or cooled by flowing through underground pipes and then through the air exchanger which replicates the temperature of the air inside the house.  The system provides fresh air when needed and replaces some ventilating fans.  Air leakage occurs through this tempered system rather than through walls, windows and doors.
