    I don't know about houses but in factories and warehouses you need an MAU which stands for make up air unit. It's basically a fan motor from the outside but it has a heater for when the air is cold and some have AC units when the air is hot.

    I don't need a unit with a fan, or a separate heater. This fresh air duct will combine with the return from inside the house and go into the heater from there. I just need to figure out what to put on the side of the house.
