that ac exhaust box is sweet man. are you using a fan too ? how long a run of ducting for the exhaust? i need to do the same thing
yeah the upstairs only has 6ft of duct straight into the attic, downstairs is about 20ft. upstairs just has a booster but I'm gonna put a 5-600cfm inline on both. it works great as long as you cut the sides out and seal the exhaust and ambient (intake) zones from each other.. otherwise the exhaust fan will force hot air into the ambient zone lowering efficiency. i used that high temp foil tape since the compressor get to about 300 degrees F.
