Buy this unit
Sold on Amazon — DIY install
A window AC is a self-install unit: you set it in the window (or wall sleeve), no contractor or refrigerant charge needed. We could not confirm a listing for this exact model number, so this opens an Amazon search for a TCL window AC of this capacity — one we checked returns real results. Compare whatever you find against the certified specs above.
Sized for ~750 sq ft — measure your room and check your window type before you buy.

Fit & install — does it fit your window?
Efficiency & running cost — computed by Verified HVAC Data
Worth keeping in proportion: every unit in the 15,000 BTU class runs within $43 a year of every other. The gap between the cheapest and dearest to buy at this size is 5× 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 15,000 BTU right for my room, or should I size up?
About 750 square feet is the guide figure, and 7 certified units sit on that shelf. The next shelf up is 18,000 BTU (17 units), about 900 sq ft. Below it, 14,000 BTU (33 units) covers about 700 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 T15WQ2S 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 25" wide × 17" tall × 26" deep (certified 2025-08-22), and 26" wide × 15" tall × 28" 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.
