A good fit if…
- You want a quieter room and a usable window - the window closes into the U, so the compressor sits outside the glass.
- You want to plug it into an ordinary outlet - it runs on 115 V.
Think twice if…
- Running cost matters most - its CEER is below average for 5,000-6,000 BTU window air conditioners.
- You also need heat - it cools only.

Questions
- How many square feet does the TCL W5WC72 cool?
- At 5,000 BTU/h it suits a room of about 100 to 150 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 110-165 sq ft; in a very sunny one it shrinks to 90-135 sq ft. A kitchen needs 4,000 BTU more.
- How many watts and amps does the TCL W5WC72 use?
- About 365 watts at full power (5,000 BTU/h divided by its CEER of 13.7), which is 3.2 amps at 115 V. That is 32 W less than the typical unit in its class (397 W), or $4 a year cheaper to run at 18.0¢/kWh. Its inverter compressor slows down instead of cycling, so real use is usually lower. Its CEER beats 8% of the 12 units in the class.
- Can the TCL W5WC72 run on a standard outlet?
- Yes. It runs on 115 V and draws about 3.2 A, well inside a standard 15 A outlet, but do not share the circuit with a space heater, microwave or other big load. Every certified unit in this class is 115 V.
- What are the dimensions of the TCL W5WC72, and will it fit my window?
- 16" W × 12.5" H × 15.5" D, 42 lb. It is narrower than 55% of its 11 competitors and lighter than 45% of them. The window closes into the U-shaped slot, so measure the opening height as well as the width: you need at least the unit's 16" width between the frame sides.
- Is the TCL W5WC72 U-shaped design an advantage?
- Mostly yes. The sash closes into the unit, so the window stays sealed and daylight comes in, and the compressor is outside the glass, which cuts noise indoors. The trade-off is a window that must slide up and down, and a few extra steps to fit the foam seals.
- Can the TCL W5WC72 also heat the room?
- No, it only cools. If you also need heat, 0 certified units in this class can do both; see the list of air conditioners with heat.
- Is the TCL W5WC72 worth buying to replace an old air conditioner?
- An old unit of the same size at 9 CEER would cost about $75 a year to run at 750 hours and 18.0¢/kWh; this one costs about $49, so it saves roughly $26 a year.
- Is the TCL W5WC72 the same as the TCL T05WV9M?
- As far as the certified data goes, yes. ENERGY STAR lists 8 model numbers with the same capacity, efficiency, energy use, dimensions and weight, which means the same unit sold under another brand or with a different colour or retailer code. The full list is on this page.
