A window AC is a self-install unit: you set it in the window (or wall sleeve), no contractor or refrigerant charge needed. We have not matched a retail listing for this exact model, so we are not linking one. Search your usual retailer for the model number above — and check the certified specs here against whatever you find.
Sized for ~550 sq ft — measure your room and check your window type before you buy.

Frequently asked questions
Is 12,700 BTU right for my room, or should I size up?
About 550 square feet is the guide figure, and 5 certified units sit on that shelf. The next shelf up is 14,000 BTU (33 units), about 700 sq ft. Below it, 12,000 BTU (80 units) covers about 550 sq ft. Between two shelves, take the smaller one: oversizing is the usual reason a unit cools but leaves the room clammy, which our sizing calculator explains.
Does the Friedrich KCVS12B30A need a special outlet?
Yes. It runs on 230 volts, not the 115-volt outlet a bedroom or living room normally has, so it needs a dedicated circuit installed by an electrician. Budget for that before you buy: most units in its 13,000 BTU class are 115-volt, so a same-size alternative may avoid the wiring entirely.
Will the Friedrich KCVS12B30A fit my window?
Measure your window opening first — it needs to be at least 26" wide (the cabinet width), and the unit is about 16" tall and 29" deep, roughly 110 lb. Most double-hung windows fit units in this range with the included side panels, but confirm your window's inside width and minimum height.
Sources. Certification and CEER from ENERGY STAR room-AC data and the DOE compliance certification database. Cooling capacity, dimensions and refrigerant are the manufacturer-certified values. Annual running cost, suggested room size and the percentile are computed by Verified HVAC Data from published ratings and EIA U.S. average electricity prices — see our methodology. Refrigerant GWP is the IPCC value. We publish no star ratings and take no payment for placement. "Not published" means the source registry doesn't disclose it — we never fill a spec with a guess.
