I bought this to replace a failed unit in an addition to my house. This room is not on the ductwork for the central A/C, so it needs its own unit.

This model is slightly wider than my old unit, so I also replaced the sleeve (EA108T). This is a through-the-wall mount and requires a sleeve, though if there is an existing sleeve and it's large enough, you can use that. The unit comes with a new grill for the back of the sleeve, and various foam pieces to apply to the sleeve to make the unit fit. Note that you must remove any existing grill or plate from the back of the sleeve.

Mounting the sleeve in the wall is the hard part; the A/C itself just slides in. Both the A/C and heat work fine.

As with any heavy item, it's prone to being damaged by the delivery company. Inspect it carefully and file a complaint if it's damaged. The box for mine had some dings in it, but the unit itself was fine.

Had one issue: Power cable to the blower fan was loose and hanging into fan blades. Took cover off to and reattached cable with cable ties. The factory cable hook is very poorly made and will not hold cable during shipping. Unit is quiet and heats/cools well.

I like it. It was easy to install. Effectively cools a 16' x 24' work shop in Southern Mississippi summers. Heats great also. Bought this instead of a central unit or a Japanese split unit. Much better price and just as effective.
