Model
Seasons ST14VA2
Rank #340 means 339 of the 404 room air conditioner models we track cost less to run each year; the 18th efficiency percentile means it uses less energy for its size than 18% of those models.
What does the Seasons ST14VA2 cost to run per year?
The Seasons ST14VA2 costs about $140 a year to run, sitting well up the cheapest-to-run leaderboard, rank #340 of 404. It uses 49% less energy than the U.S. federal standard model in its class, which would cost about $275/yr to run, a saving of roughly $135 a year. Its 18th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. At a CEER of 13.9, its combined energy efficiency ratio is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Midea MWEUTW-14CRFN8-MCM9 at $140/yr runs a little cheaper and the Friedrich WCVT12B10A at $142/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 ST14VA2's $140/yr adds up to roughly $1400 in electricity alone, before purchase price or repairs.
Also sold as: Midea MAT14R2FWTK.
By the numbers
The Seasons ST14VA2 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 $140/yr, here is what the Seasons ST14VA2 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 ST14VA2 costs about $1400. That is roughly $1350 less than a standard model in its class, which would run closer to $2750 over the same ten years.
How the Seasons ST14VA2 compares
The room air conditioner class we track runs from $51 to $389 a year. At $140/yr, it runs about $41 a year above the class median of $99, and it is about $89 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $275/yr, the Seasons ST14VA2 uses 49% less energy.
What drives its running cost
At 14000 BTU/hr, the Seasons ST14VA2 is a large room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up. Its CEER of 13.9, below the class median of 15, reflects combined energy efficiency ratio: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 ST14VA2 cheap to run?
Not especially. At $140 a year it ranks #340 of 404 room air conditioner models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Seasons ST14VA2 cost per month?
Roughly $11.68/mo, spreading the $140/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 755 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $140 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Seasons ST14VA2 for its size?
18th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
