 And people are going, why is my house hotter when I turn that on? It's because it's pulling cold air out of your house and sending it outside. Yes, you did reduce the attic temperature, but you reduced it by pulling out the cold air that's in your house. So that's counterintuitive. So you want to make sure that you go through and seal up all those areas. And really the only way to do that is to pull the insulation back and just go through it on a nice winter day when it's not hot up there and caulk that all in, seal it up, spray foam, do what you got to do.
