Hey, Sarah, thank you for the question. A couple things, you're going from 1027 to 1227, which is, you know, you're adding 200 square feet and three and a half ton unit. That comes out to about 350 square foot a ton, which sounds a little large to me. Sounds like too much of a unit. But really won't know unless you do a load analysis on the home. It's gonna, you know, things are going to factor into it, insulation in the walls, in the ceiling, in the floor, windows. What kind of windows where the windows at Northeast, southwest. But it sounds like a little bit of a tube. That unit is too big because right now it's sitting on 1027 square feet, which is really sounds big. So a couple concerns is that is the unit size properly and do you have a duct system that can handle a3Nav tonight.
