Range hoods need Makeup Air

We can build a house so tight even Germans would be impressed. And then we forget about how to deal with a clothes dryer. Or we put in a kitchen range hood. Or we build a house with a fireplace. Or then we attach a garage. What are the odds that a house will have a clothes dryer, a kitchen range hood, a fireplace or an attached garage? I have news for you installing a cheap exhaust fan does not fix things. Installing an expensive one does not fix things either. Sucking does not work. Sucking causes air to come into your building through places you probably don’t want air to come through while carrying stuff or picking up stuff you don’t want inside your building. Sucking also causes bad things to happen to other things in your house like water heaters and furnaces and boilers and fireplaces. If you suck you have to blow or you are doomed. And the more you suck the more you have to blow – especially in a tight house.
