Model
Seasons ST08VB1
Rank #120 means 119 of the 404 room air conditioner models we track cost less to run each year; the 70th efficiency percentile means it uses less energy for its size than 70% of those models.
What does the Seasons ST08VB1 cost to run per year?
At about $79 a year, the Seasons ST08VB1 undercuts most room air conditioner models we track on running cost, rank #120 of 404. It uses 47% less energy than the U.S. federal standard model in its class, which would cost about $149/yr to run, a saving of roughly $70 a year. Capacity-normalized, it ranks ahead of 70% of room air conditioner models we track, a reasonably strong result for the class. At a CEER of 14.1, 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-08CRFN8-BCN1 at $79/yr runs a little cheaper and the Ge Appliances AWGP08W**# at $84/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 ST08VB1's $79/yr adds up to roughly $790 in electricity alone, before purchase price or repairs.

By the numbers
The Seasons ST08VB1 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 $79/yr, here is what the Seasons ST08VB1 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 ST08VB1 costs about $790. That is roughly $700 less than a standard model in its class, which would run closer to $1490 over the same ten years.
How the Seasons ST08VB1 compares
The room air conditioner class we track runs from $51 to $389 a year. At $79/yr, it runs about $20 a year cheaper than the class median of $99, and it is about $28 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $149/yr, the Seasons ST08VB1 uses 47% less energy.
What drives its running cost
At 8000 BTU/hr, the Seasons ST08VB1 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). 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 ST08VB1 cheap to run?
Yes. Its $79/yr running cost puts it at rank #120 of 404, below what most room air conditioner models we track cost to run.
How much does the Seasons ST08VB1 cost per month?
About $6.58 a month, which is the $79 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: 426 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $79 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Seasons ST08VB1 for its size?
70th percentile once size is factored in, a fairly typical result for the class.
