Will it cool your room?
This has more cooling than your 861 sq ft room needs. It can short-cycle and leave the air cool but humid.
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.

- Wall sleeve
- Fits a window, or a Friedrich Kuhl sleeve of its size
Will it fit your wall sleeve?
Its cabinet is its sleeve: it goes in a window, or through a wall in an opening sized for its chassis (Q, S, M or L). Friedrich says its sleeve sizes have not changed in over 45 years, so a new Kuhl fits an existing Friedrich sleeve of the same size. Its side air intakes must stay clear, so the wall can be no thicker than Friedrich's limit for that size (8½ in. for Q, 7⅜ in. for S and M, 15⅛ in. for L). Source: Friedrich Kuhl brochure (sleeve sizes)
Every through-the-wall AC and PTAC by the sleeve it fitsWhat is good
- Uses R-32 (GWP 675), the low-GWP class new US residential equipment moved to.
What to watch
- Its CEER 13.2 is less efficient than 43 of the 47 other window units we list with a published CEER.
Installation & the rules that apply
This is a window-or-wall air conditioner. In a window it follows the same rules as any window unit. Through a wall it sits in the maker's own sleeve, and cutting a new opening usually needs a building permit and, in a condo, co-op or historic building, approval first.
