Model
Seasons ST10VB1
Rank #198 means 197 of the 404 room air conditioner models we track cost less to run each year; the 51st efficiency percentile means it uses less energy for its size than 51% of those models.
What does the Seasons ST10VB1 cost to run per year?
Do the math and the Seasons ST10VB1's $99/yr puts it at rank #198 of 404, right around the class average. It uses 47% less energy than the U.S. federal standard model in its class, which would cost about $186/yr to run, a saving of roughly $87 a year. Adjusted for size, it is more efficient than 51% of room air conditioner models we track, a middling result. The CEER figure of 14.1 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 Midea MWEUTW-10CRFN8-MCN1 at $99/yr runs a little cheaper and the Seasons ST10VB2 at $99/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 Seasons ST10VB1's $99/yr adds up to roughly $990 in electricity alone, before purchase price or repairs.
Also sold as: Midea MAT10R1FWTK.
By the numbers
The Seasons ST10VB1 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 $99/yr, here is what the Seasons ST10VB1 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Seasons ST10VB1 costs about $990. That is roughly $870 less than a standard model in its class, which would run closer to $1860 over the same ten years.
How the Seasons ST10VB1 compares
The room air conditioner class we track runs from $51 to $389 a year. At $99/yr, it sits right on the class median of $99, and it is about $48 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $186/yr, the Seasons ST10VB1 uses 47% less energy.
What drives its running cost
At 10000 BTU/hr, the Seasons ST10VB1 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 14.1 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 Seasons ST10VB1 cheap to run?
It is about average. At $99 a year it ranks #198 of 404 room air conditioner models we track, close to the middle of its class on running cost.
How much does the Seasons ST10VB1 cost per month?
Roughly $8.23/mo, spreading the $99/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 532 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $99 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Seasons ST10VB1 for its size?
51st percentile once size is factored in, a fairly typical result for the class.
