What does the Seasons ST10VB2 cost to run per year?

The Seasons ST10VB2 holds rank #198 of 404 on running cost, at about $99 a year, an unremarkable but typical figure for the class. 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. Capacity-normalized, it ranks ahead of 51% of room air conditioner models we track, right in the class's middle band. Its CEER of 14.1 reflects combined energy efficiency ratio, one of the class's core efficiency levers.

Immediately around it on the leaderboard, the Seasons ST10VB1 at $99/yr runs a little cheaper and the Friedrich KHVS10B11A at $101/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 ST10VB2's $99/yr adds up to roughly $990 in electricity alone, before purchase price or repairs.

What it costs you over time

Running cost is an every-year number, so it compounds. At $99/yr, here is what the Seasons ST10VB2 adds up to before purchase price, water, or repairs enter the math.

1 year$99
5 years$495
10 years$990

Left running for a decade at today's US average rate, the Seasons ST10VB2 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.

What drives its running cost

At 10000 BTU/hr, the Seasons ST10VB2 is a small room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. Its CEER of 14.1, 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). 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 Seasons ST10VB2 cheap to run?

Roughly, yes. Its $99/yr figure is close to the class median, ranking #198 of 404, neither a bargain nor a splurge on running cost.

How much does the Seasons ST10VB2 cost per month?

About $8.23 a month, which is the $99 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: 532 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $99 a year. It covers electricity only, not the purchase price, water, or installation.

How efficient is the Seasons ST10VB2 for its size?

51st percentile once size is factored in, a fairly typical result for the class.
