Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) allow you to replace stale indoor air with fresher, cleaner outdoor air.
*ERV not recommended where temperatures fall
below 25°F (-4°C) for more than five days.
**ERVs are recommended in regions where high outdoor
humidity is cause for operating air conditioning/
dehumidification more frequently than heating system.
In a sense, ERVs and HRVs are like the lungs of your house. They take in outdoor air for circulation, while expelling odors, chemical vapors and pollutants outside your home. So when you’re inside, you’re always breathing in air that feels better. Best of all, HRVs and ERVs transfer this stagnant air to the outside without wasting the energy you’ve spent heating, cooling and dehumidifying it.
The decision to choose between and HRV and ERV is based largely on where you live. HRVs are recommended if you live in Canada or a northern or central region of the U.S. ERVs are only recommended for southern locations with high humidity.
