TCL W6WC72-BI
window air conditioner · 6,000 BTU cooling · fits ~300 sq ft
A window AC rated 6,000 BTU — enough cooling for a room of roughly 300 square feet (the 20-BTU-per-square-foot rule).
What actually decides this purchase
We publish 17 units at 6,000 BTU. They run within $7 a year of each other — but they sell for $228 to $350, a 1.5× spread. Efficiency is not what decides this purchase at 6,000 BTU; price, noise and whether it fits your window are. Here is where this unit lands.
We have no tracked price for this unit, so here is the rule instead. At 6,000 BTU the field runs $228 to $350, median $349, and every one of them runs within $7 a year of every other — so price is the decision and efficiency is the tiebreak. On the certified specs we do hold, this one ranks 8th of 17 in its class. If the price you are quoted is above $349, buy something else. Worth comparing against the LG LW6023IVSM at $228 and the Midea MAW06V1QWT at 32 dBA for $349.
Price
Not tracked
We have no verified retail listing for this certificate. Units at this size run $228–$350.
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.

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 ~300 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 6,000 BTU class runs within $7 a year of every other. The gap between the cheapest and dearest to buy at this size is 17× 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 6,000 BTU right for my room, or should I size up?
About 300 square feet is the guide figure, and 17 certified units sit on that shelf. The next shelf up is 8,000 BTU (84 units), about 400 sq ft. Below it, 5,000 BTU (8 units) covers about 250 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 W6WC72-BI fit my window?
Measure your window opening first — it needs to be at least 21" wide (the cabinet width), and the unit is about 13" tall and 19" deep, roughly 52 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.
