Difference Between an ERV and HRV


How fresh is the air in your home? During the warmer months, an open window or door helps exchange the stale air in your home, but when the temperature drops and homes are sealed people tend to notice that the air in their homes is very stale. A Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV) help by exchanging the air inside your home with fresh, outside air.

HRV – As the air is exchanged, the heat is pulled from the stale air and transferred to the incoming air. This helps with efficiency as you’re not introducing freezing cold air into your home.

ERV – Along with transferring heat, an ERV also transfers moisture. In the winter, an ERV system transfers moisture to the incoming air and in the summer, it pulls the humidity out of the outside air. This helps keep your indoor comfort high while also being extremely energy efficient.

While both systems will help improve indoor air quality, for our climate, we recommend our clients install an ERV system. Since our winters are extremely dry and summers are humid, the ability to transfer moisture will help ensure year-round comfort.

Importance of Indoor Air Quality
Indoor air pollution has a number of harmful effects on your short-term and long-term health and those with pre-existing respiratory problems need to be especially careful. Pollutants, irritants and allergens can cause breathing issues, eye and skin irritation, headaches and even fatigue.
