In 2008 or 9, they changed the code in North Carolina. Anything over 1600 square feet, you have to have two returns in the home instead of one return. The house is big enough and I would always recommend having multiple returns because out of 15 years I've never been to the home and been like, wow, we have too many returns here. That's never been the case. What has been the case most of the time is you go to a house and you say there's not enough return here. Stop shutting that door. You don't have return. The returns will on this side of the house. So with two returns in this 1700 square foot house, we'll say you probably have one return on one side and one return on the other side. So probably how it's laid out is that you have a room or bedrooms on this side with the return you have the kitchen, living room in middle and on this side you have rooms and a bedroom with another return. See how you see in the house? So that's why you have two returns. You want to make it as easy as possible for the air to get back to the unit. So the bigger the return and the more you have in these different locations where it can be closed off, the better because you want to make it very easy. Otherwise the unit is going to get the air needs. It's going to suck it through the crawl space to the attic. The outside it's going to get the air it wants to get to operate. But you want to control it. You want it to be cool or warm filtered air from your return, not from the outside, which is unconditioned air. Right. So that'll save you energy and the unit will not have to work as hard to get the air back to it. So that is why you have two returns. Two returns is not a bad thing. I'm glad you have two returns because you need two returns. Because if you have that one return on this side of the house and you had this other 1600 square feet, all that air has to get back to this side of the house one way or another. And we all know it's going to be very difficult on that back room when you shut the door because that's your junk room. You have all your stuff in there. You don't want people to see it. It's going to be very hard for the air that's coming out to then get back to their turn. Is it, Is there a junk room?
