The previous question's answer listed pages 9-17 for sleeve options but the items on those pages are not sold on Home Depot's website.
Is it possible to get a list of all the sleeves that will fit this unit and are on the Home Depot website?

Customer Reviews

Rated 3.0 out of 5 by 3 reviewers.
Rated 3.0 out of 5.0 by Louder than expected but affective Ignore my rating. They make you enter one. Having a unit for less that three months hardly qualifies me to give it a rating. Full Disclosure: We only bought this unit because, at the time, the comparable GE Model I wanted was not available and would not be for several months. That said, the unit: 12k btu @115v is very effective, but louder than expected (I have no idea what to make of decibel values) Still, it chills a 15x25 room quite effectively. When I turned the unit on, the fan spins up and sounds like it's brushing up against something in the interior. But fortunately the noise from the unit drowns it out. The remote takes some getting used to. It's poorly explained and off doesn't mean off. I've only been using the unit about a month or two so all I can say is that it hasn't broken yet and based on that, yes, for the price, I'd recommend it. June 9, 2015
Rated 5.0 out of 5.0 by Wall Air Conditioner Everything that i read stated that this was a nice AC and the 12,000 BTU was nice for this price. I found higher priced AC's with less power. Disregard the last review as there was no noes that says that this is a Heater / AC machine. This is an AC only unit. March 30, 2015
Rated 1.0 out of 5.0 by DOES NOT HAVE A HEATER AS STATED IN DESCRIPTION I purchased this very expensive a/c unit because it was supposed to have a heater. I only found out after my contractor had cut a hole in the wall and framed in and installed the unit in my rental property that it does not have a heater. I would never have paid this much for a no name a/c unit, but I needed a heater and this was one of the only ones. NOT HAPPY! August 30, 2014
