We get a lot of questions about ERVs and HRVs and what the difference between both is. An HRV (heat recovery ventilator) system supplies continuous fresh air from outside the house. ERVs (energy recovery ventilators) can exchange both heat and moisture. This is a great system to improve your indoor air quality especially if you live in extreme weather with humid summers and dry winters. Panasonic | Mike Holmes Jr.

We installed an ERV (instead of an HRV) on a new project, and I asked Sonny from Panasonic to explain the difference. | Sherry Holmes
