Heat Recovery VentilatorsBreathe easy with these energy savings.
Don’t Send Conditioned Air Out the Window
Heat recovery ventilators (HRVs) introduce fresh air into the home without losing the conditioning of the inside air, reducing heating and cooling costs. They use a heat exchanger to transfer heat from the warm inside exhaust air to the fresh, but cold, outside supply air (or vice versa in the summer). HRVs can be added to an existing HVAC system or built into a new one.
Ventilation Without Heat Loss
HRVs are especially useful in homes that have been highly insulated and air sealed. Proper ventilation is important to prevent buildup of indoor allergens and moisture, which can lead to mold. HRVs provide that ventilation without wasting the energy already used to heat or cool the air in your home.
