It is now possible to exchange stale indoor air with fresh outdoor air without compromising the energy efficiency of your home. Heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) exchanging stale, recirculated indoor air with fresh, filtered outside air, and no energy is wasted.
HRVs and ERVs are electronically powered units that circulate air throughout your home using the existing forced-air system or specially installed ducts. These units pump stale air out of your home and replace it with an equal volume of fresh outside air. An HRV is a compact unit that conditions the temperature of the outside air, while an ERV is a packaged unit that conditions both the temperature and humidity of the outside air. Because these units condition the air before it enters the home, your energy costs remain stable.
