Home The Building Science Behind Fresh Air Systems In Your Home

Sponsored Video

Do you need a dehumidifier, an energy recovery ventilator, a heat recovery ventilator, or both? If you've been following Matt for a while, you know he's a big fan of Ultra-Aire Dehumidifiers. They're a great fit for down in the hot climates of Texas, but in other parts of the country there are different needs. In this video, we'll explore train ERV energy recovery ventilators that bring air in through its core and sends air back out. At the same time it's sucking air in from the house to the outside and fresh air is being supplied to the house. An ERV, different from an HRV, moves moisture, which is an added plus. When inside air is more dry than outside, the air streams on the inside of the machine will mix in with humid air outside and ensure you're getting fresh air on the inside, despite outside conditions.

Matt reccommends that every home in the South should have a dehumidifier, but do you need an ERV? Yes. But what about coastal states where it's cold in the Winter but mild in the Spring and Fall? Those areas might need an ERV, too, since it's going to move both heat and moisture.

If you can't decide whether to get an ERV or an HRV, get an ERV. 

Matt will take a look at a few Ultra-Aire models. Browse the models here
