No verified online listing

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 ~435 sq ft — measure your room and check your window type before you buy.

Frequently asked questions

Is 8,700 BTU right for my room, or should I size up?

About 435 square feet is the guide figure, and 6 certified units sit on that shelf. The next shelf up is 10,000 BTU (81 units), about 500 sq ft. Below it, 8,000 BTU (84 units) covers about 400 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 Kühl KCVS08B10B qualify for efficiency rebates?

It meets ENERGY STAR Most Efficient, the top tier some utility rebate programmes require. 5 of the 6 units in its 9,000 BTU class reach that tier, so it is one of several options at this size. Rebates are set by your state and utility, not by the manufacturer — check the programmes for your area.

Will the Kühl KCVS08B10B 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 70 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.
