Model
Tcl W10WC72-B
Rank #127 means 126 of the 404 room air conditioner models we track cost less to run each year; the 69th efficiency percentile means it uses less energy for its size than 69% of those models.
What does the Tcl W10WC72-B cost to run per year?
At $87 a year to run, the Tcl W10WC72-B runs cheaper than most models in its class, ranking #127 of 404 room air conditioner models we track. It uses 47% less energy than the U.S. federal standard model in its class, which would cost about $164/yr to run, a saving of roughly $77 a year. Its 69th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. Its CEER of 16 reflects combined energy efficiency ratio, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Tcl W10WC72 at $87/yr runs a little cheaper and the Ge Profile AHTR10ACH2 at $90/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A room air conditioner typically stays in service for somewhere around 10 years; over that span, the Tcl W10WC72-B's $87/yr adds up to roughly $870 in electricity alone, before purchase price or repairs.

By the numbers
The Tcl W10WC72-B normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $87/yr, here is what the Tcl W10WC72-B adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Tcl W10WC72-B costs about $870. That is roughly $770 less than a standard model in its class, which would run closer to $1640 over the same ten years.
How the Tcl W10WC72-B compares
The room air conditioner class we track runs from $51 to $389 a year. At $87/yr, it runs about $12 a year cheaper than the class median of $99, and it is about $36 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $164/yr, the Tcl W10WC72-B uses 47% less energy.
What drives its running cost
At 10000 BTU/hr, the Tcl W10WC72-B is a small room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, and smaller room air conditioner models generally cost less to run for the same job, all else being equal. The CEER of 16 on this model, above the class median of 15, measures combined energy efficiency ratio; it is the number to compare directly against another model's CEER if capacity is similar.
- Combined Energy Efficiency Ratio (CEER). CEER captures cooling output per watt, including standby power; a higher CEER means less electricity for the same BTU of cooling.
- BTU cooling capacity. A higher-BTU unit is sized for a bigger room and generally uses more electricity per hour of operation than a smaller unit, regardless of efficiency.
- Thermostat and mode usage. Running on a fixed low temperature around the clock uses far more energy than using a thermostat setting, eco mode, or a timer to match cooling to when the room is actually occupied.
Common questions
Is the Tcl W10WC72-B cheap to run?
Yes, relatively. At $87 a year it ranks #127 of 404 room air conditioner models we track, in the cheaper part of its class to run.
How much does the Tcl W10WC72-B cost per month?
Roughly $7.25/mo, spreading the $87/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 469 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $87 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Tcl W10WC72-B for its size?
69th percentile once size is factored in, a fairly typical result for the class.
