Will it cool your room?
This unit's cooling matches a 600 sq ft room. Set your room size to check the fit for your space.
Estimated from ENERGY STAR's published annual energy use at about 750 hours of cooling a year (the DOE test standard) and the US average electricity price of 18.44¢/kWh (U.S. Energy Information Administration, Electric Power Monthly Table 5.6.A (residential average, May 2026)). A standardized figure for comparison; your real cost depends on how much you run it, your local rate and your climate.
Local rates vary widely (about 15¢/kWh in Florida to 33¢ in California), and hotter regions run their AC more hours, so your real cost differs.

Will it fit your wall sleeve?
Made for existing 27-inch sleeves, including Fedders A sleeves and, with Friedrich's baffle kit, the deeper Fedders B; it mounts flush with the outside wall. A new installation needs Friedrich's WSE or WSEZ sleeve (27 x 16¾ x 16¾ in.), sold separately. Source: Friedrich WallMaster product page
Every through-the-wall AC and PTAC by the sleeve it fitsWhat is good
- ENERGY STAR certified, which 7 of the 50 through-the-wall units we list offer.
- Uses R-32 (GWP 675), the low-GWP class new US residential equipment moved to.
Installation & the rules that apply
This is a through-the-wall air conditioner. It sits in a sleeve built into an exterior wall, so the window-unit mounting and bracket rules do not apply to it. Swapping it into an existing sleeve is a like-for-like replacement; cutting a new opening changes the building's exterior wall, which usually needs a building permit and, in a condo, co-op or historic building, approval first.
