TCL T10WQ2S
window air conditioner · 10,000 BTU cooling · fits ~500 sq ft
A window AC rated 10,000 BTU — enough cooling for a room of roughly 500 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 $440 this sits above the 10,000 BTU median of $427 — $13 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.
Window fit
26–36" wide
From the manufacturer's submittal sheet — the range the unit is designed to fit.

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 10,000 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.

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.
Refrigerant & identity
Brand, warranty & reliability
A large Chinese electronics maker selling low-cost mini-splits; units cool well and reviewers like the smart features, but the HVAC track record is short and the North American dealer/parts network is thin.
Reliability is our read of published brand assessments (source), not a certified rating — real-world dependability hinges on a correct install more than the brand. Warranty terms are the manufacturer's (policy) and almost always require online registration within 60–90 days for the full length.

Frequently asked questions
Is 10,000 BTU right for my room, or should I size up?
About 500 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.
Will the TCL T10WQ2S fit my window?
We can't give you one answer honestly. 2 certification records exist for this model and they list different cabinet dimensions, so we don't publish a single figure. The records list 21" wide × 13" tall × 19" deep (certified 2025-08-22), and 24" wide × 16" tall × 21" deep (certified 2025-08-21). Measure your opening, then confirm the dimensions against the exact unit the seller is shipping before you buy.
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.
