We recently converted another small window (side vented) AC sleeve that was installed through the wall to a Universal sized thru wall (rear vented) sleeve. Many buildings throughout SK and MB were built with small AC sleeves that only fit a window AC. These sleeves cause issues with moisture leaking into the building envelope, replacement sizing and insufficient BTU’s due to the limited sleeve size.
We changed this one over to alleviate all of these issues in the future.
