Friedrich KHVS10B11A
window air conditioner · 10,200 BTU cooling · fits ~510 sq ft
A window AC rated 10,200 BTU — enough cooling for a room of roughly 510 square feet (the 20-BTU-per-square-foot rule).
What actually decides this purchase
We publish 81 units at 10,000 BTU. They run within $27 a year of each other — but they sell for $298 to $619, a 2.1× spread. Efficiency is not what decides this purchase at 10,000 BTU; price, noise and whether it fits your window are. Here is where this unit lands.
At $549 this sits above the 10,000 BTU median of $427 — $122 more for cooling that costs the same to run, since the whole class is within $27 a year of itself. That premium has to buy something you can name: quieter running, a better warranty, a fit your window needs. Worth comparing against the BLACK+DECKER BD10NWES at $298 and the Friedrich CCV10A10A at 32 dBA for $619.

Noise
Not published
The maker publishes no dBA figure we could verify, and noise is not part of the DOE certification. It is the most common complaint about window units, so treat its absence as a real unknown.

A window AC is a self-install unit: you set it in the window (or wall sleeve), no contractor or refrigerant charge needed. We verified this listing against the certified record: same brand, the same 10,200 BTU cooling capacity, the same window AC form factor, and in stock at the price shown. Its title doesn’t carry this model number, so treat it as the current equivalent rather than a guaranteed identical SKU.
Sized for ~510 sq ft — measure your room and check your window type before you buy.

Efficiency & running cost — computed by Verified HVAC Data
Worth keeping in proportion: every unit in the 10,000 BTU class runs within $27 a year of every other. The gap between the cheapest and dearest to buy at this size is 12× larger. Efficiency is the smallest number on this page, which is why it is not at the top of it.

Frequently asked questions
Is 10,200 BTU right for my room, or should I size up?
About 510 square feet is the guide figure, and 81 certified units sit on that shelf. The next shelf up is 11,000 BTU (4 units), about 550 sq ft. Below it, 9,000 BTU (6 units) covers about 450 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 KHVS10B11A heat as well as cool?
Yes — it is certified with a heating mode, so it works as a shoulder-season heater as well as an air conditioner. Only 30 of the 389 room ACs we publish do. It is supplemental heat for one room, not a replacement for a home heating system.
Will the Friedrich KHVS10B11A 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 105 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.
