Air ExchangerIn the winter, fresh air is cold air.  And your home and businesses are built to keep the cold air out.  But you can keep the air inside fresh year-round and conserve energy at the same time with the use of a heat-recovery air exchanger, also called an air-to-air heat exchanger.

An average home should have at least .35 air changes per hour (ACH)  Newer, high-efficiency homes generally have ACH of less that .35, with many as low as .05, which leads to poor air quality and consequent health conditions such a headaches and allergies.

In addition to providing a fresh air supply, the air exchangers used in Faganel Builders Millennium III® Green homes help reduce allergens and unhealthy indoor air pollutants such as radon and smoke.  Heat-recovery air exchangers capture up to 85 percent of the heat from indoor air and transfer it to the fresh incoming air before exhausting.
