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.

At a glance
Who it's for
Cooling a single room of about 300 sq ft — a bedroom, office or apartment — that you install yourself, no contractor.
The standout number
CEER 13.7 — the room-AC efficiency number; higher means a lower summer electric bill.
The catch
Window units only fit windows in their size range — measure your window width and height against the dimensions below before you buy.

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.
Rebates & incentives
This unit is ENERGY STAR certified, which a few utility rebates ask for. The federal 25C credit expired December 31, 2025, and it never covered room ACs anyway; the live money is state and utility programs. Check what applies where you live on our rebates page.

Frequently asked questions
What size room does the TCL W6WC72 cool?
It puts out 6,000 BTU of cooling. The common rule of thumb is 20 BTU per square foot, so it suits a room of about 300 square feet with 8-foot ceilings. Sunny rooms, kitchens or spaces with many people need a bit more; heavily shaded rooms a bit less.
How efficient is the TCL W6WC72?
It is rated CEER 13.7. CEER (Combined Energy Efficiency Ratio) is the DOE test number for room air conditioners — the higher it is, the less electricity the unit uses for the same cooling. This model uses about 25% less energy than the federal minimum for its size.
What does the TCL W6WC72 cost to run?
We estimate about $62 a year to run it — roughly 329 kWh, at U.S. average electricity prices and a typical cooling season. Your climate and local power price move the number; running it fewer hours costs less.
Will the TCL W6WC72 fit my window?
Measure your window opening first — it needs to be at least 19" wide (the cabinet width), and the unit is about 13" tall and 18" deep, roughly 40 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.
Where can I buy the TCL W6WC72?
Room air conditioners are self-install and sold online. Our "Find it on Amazon" button opens a live search for this exact brand and model so you can compare current prices and sellers. It sets in the window (or wall sleeve) yourself — no contractor and no refrigerant charge.
