Model
Tcl T06WV9RB
Rank #16 means 15 of the 404 room air conditioner models we track cost less to run each year; the 94th efficiency percentile means it uses less energy for its size than 94% of those models.
What does the Tcl T06WV9RB cost to run per year?
Few room air conditioner models we track undercut the Tcl T06WV9RB on cost; at about $61 a year it holds rank #16 of 404. It uses 25% less energy than the U.S. federal standard model in its class, which would cost about $81/yr to run, a saving of roughly $20 a year. Adjusted for its ceer, it is more efficient than 94% of room air conditioner models we track, a strong result once size is taken into account. The CEER figure of 13.7 on this model captures combined energy efficiency ratio, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Tcl T06WV9R at $61/yr runs a little cheaper and the Tcl W6WC72 at $61/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 T06WV9RB's $61/yr adds up to roughly $610 in electricity alone, before purchase price or repairs.
Also sold as: Hisense WCT06W25A.
By the numbers
The Tcl T06WV9RB 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 $61/yr, here is what the Tcl T06WV9RB 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 T06WV9RB costs about $610. That is roughly $200 less than a standard model in its class, which would run closer to $810 over the same ten years.
How the Tcl T06WV9RB compares
The room air conditioner class we track runs from $51 to $389 a year. At $61/yr, it runs about $38 a year cheaper than the class median of $99, and it is about $10 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $81/yr, the Tcl T06WV9RB uses 25% less energy.
What drives its running cost
At 6000 BTU/hr, the Tcl T06WV9RB is a small room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. The CEER of 13.7 on this model, below 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 T06WV9RB cheap to run?
Yes, relatively. At $61 a year it ranks #16 of 404 room air conditioner models we track, in the cheaper part of its class to run.
How much does the Tcl T06WV9RB cost per month?
Roughly $5.08/mo, spreading the $61/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 329 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $61 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Tcl T06WV9RB for its size?
94th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
