Model
Tcl W10WC72
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 cost to run per year?
At about $87 a year, the Tcl W10WC72 undercuts most room air conditioner models we track on running cost, rank #127 of 404. 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 size-adjusted efficiency percentile of 69 is comfortably above the class median. 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 T10WV9SB at $87/yr runs a little cheaper and the Tcl W10WC72-B at $87/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's $87/yr adds up to roughly $870 in electricity alone, before purchase price or repairs.

By the numbers
The Tcl W10WC72 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 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 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 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 uses 47% less energy.
What drives its running cost
At 10000 BTU/hr, the Tcl W10WC72 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. Beyond size, its CEER of 16, above the class median of 15, is the class's own efficiency yardstick, combined energy efficiency ratio, and it is what separates two similarly sized models with different running costs.
- Combined Energy Efficiency Ratio (CEER). Two units with the same BTU rating can post very different running costs, and CEER is the figure that explains most of that gap.
- BTU cooling capacity. BTU rating scales with room size, and it is usually the first driver of an air conditioner's running cost, ahead of its CEER figure.
- Thermostat and mode usage. How the unit is actually operated, thermostat cycling versus a fixed setting, moves real electricity use more than the rated BTU or CEER figure alone.
Common questions
Is the Tcl W10WC72 cheap to run?
Yes. Its $87/yr running cost puts it at rank #127 of 404, below what most room air conditioner models we track cost to run.
How much does the Tcl W10WC72 cost per month?
About $7.25 a month, which is the $87 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 469 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $87 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Tcl W10WC72 for its size?
69th percentile once size is factored in, a fairly typical result for the class.
