TCL T14WV9S
window air conditioner · 14,000 BTU cooling · fits ~700 sq ft
A window AC rated 14,000 BTU — enough cooling for a room of roughly 700 square feet (the 20-BTU-per-square-foot rule).
What actually decides this purchase
We publish 33 units at 14,000 BTU. They run within $34 a year of each other — but they sell for $480 to $995, a 2.1× spread. Efficiency is not what decides this purchase at 14,000 BTU; price, noise and whether it fits your window are. Here is where this unit lands.
At $630 this sits above the 14,000 BTU median of $565 — $65 more for cooling that costs the same to run, since the whole class is within $34 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 TCL T14WV9SB at $480 and the Midea MAW14RV1CCWT at 41 dBA for $565.

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 14,000 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 14,000 BTU class runs within $34 a year of every other. The gap between the cheapest and dearest to buy at this size is 15× 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 14,000 BTU right for my room, or should I size up?
About 700 square feet is the guide figure, and 33 certified units sit on that shelf. The next shelf up is 15,000 BTU (7 units), about 750 sq ft. Below it, 13,000 BTU (5 units) covers about 650 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 TCL T14WV9S qualify for efficiency rebates?
It meets ENERGY STAR Most Efficient, the top tier some utility rebate programmes require. 12 of the 33 units in its 14,000 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 TCL T14WV9S fit my window?
Measure your window opening first — it needs to be at least 20" wide (the cabinet width), and the unit is about 15" tall and 22" deep, roughly 57 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.

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.
