Heat-Recovery Air Exchangers

In the winter, fresh air is cold air. And homes and businesses are built to keep the cold air out. But you can keep your inside air fresh year-round and conserve energy at the same time by using a heat-recovery air exchanger, also called an air-to-air heat exchanger. 

A breath of fresh air for your home  

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, which may lead to poor air quality and health conditions such as headaches and allergies. To prevent these issues, new construction building codes in some states require air exchangers to ensure an adequate supply of fresh air.

Benefits

  • Provide a constant, controlled supply of fresh air to your home.
  • Control build-up of excess moisture from daily activities such as showers, whirlpools, and cooking.
  • Reduce the concentration of allergens such as pollen, dust, and dander.
  • Reduce unhealthy indoor air pollutants, such as formaldehyde and smoke, and those emitted from paints, sprays, and cleansers.

A 'heat-recovery' type of air exchanger will capture up to 85% of the heat from indoor air and transfer it to the fresh incoming air before exhausting stale air.
