You don't need fresh air from outside. The air in your house has way more CO2 than the air outside.
Instead, I would close all windows and pull air from the room you are in most often, that is where all the co2 is.
For example in my house, my co2 is 1500ppm easily or higher. Only me and my girlfriend in a huge house. So all I do when I have tents or box grows inside the house is move air from outside the tent, to inside the tent. This makes it easy to keep the temps higher in the tent. Also the tent then acts like a small heater.
I have 4 inch fan pulling air out of the tent, and a hole at the bottom letting air come in passively.
A house is free co2. If the grow space is in a room in the house, I see no reason to try to bring in air from outside. It is a waste of free CO2.
