Blog Title: can you use existing sleeve for a new ptac unit

Main Que: I have a 20 year old Amana PTAC unit. Will a new unit slide into the existing wall sleeve?

Answer: Most likely! Measure your existing wall sleeve. If it measures 42” Wide x 16” High x 16” deep, then a new unit should slide right in. The PTAC industry has been using these standard dimensions for 30-40 years. Occasionally you’ll find an odd size that an off brand manufacturer thought would be a good idea. It wasn’t a good idea, and that odd size is probably no longer around. If you have an odd size, search the web for “Retrofit PTAC”, there are a handful of companies that specialize in replacing old units that never made it very far.
