In the winter, fresh air is cold air. And your home and business 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 heat-recovery air exchangers, also called air-to-air heat exchangers.
An average home should have at least .35 air changes per hour (ACH). Newer, high-efficiency homes generally have ACH of less than .35, with many as low as .05. That leads to poor air quality and consequent health conditions such as headaches and allergies.
In addition to providing a fresh air supply, air exchangers help reduce allergens and unhealthy indoor air pollutants such as radon and smoke. They are required by new construction building codes in some states.
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.
