Model
Danby DAC080B7IWDB-6
Rank #51 means 50 of the 404 room air conditioner models we track cost less to run each year; the 85th efficiency percentile means it uses less energy for its size than 85% of those models.
What does the Danby DAC080B7IWDB-6 cost to run per year?
The Danby DAC080B7IWDB-6 runs for about $74 a year, landing it near the bottom of the cost table at rank #51 of 404 room air conditioner models we track. It uses 38% less energy than the U.S. federal standard model in its class, which would cost about $120/yr to run, a saving of roughly $46 a year. Few room air conditioner models we track beat it on size-adjusted efficiency; it edges out 85% of the class once capacity is normalized. At a CEER of 15, 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 Comfort Aire RXTS-81A at $74/yr runs a little cheaper and the Danby DAC080B8IWDB-6 at $74/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 Danby DAC080B7IWDB-6's $74/yr adds up to roughly $740 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BD08NWES.
By the numbers
The Danby DAC080B7IWDB-6 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 $74/yr, here is what the Danby DAC080B7IWDB-6 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Danby DAC080B7IWDB-6 costs about $740. That is roughly $460 less than a standard model in its class, which would run closer to $1200 over the same ten years.
How the Danby DAC080B7IWDB-6 compares
The room air conditioner class we track runs from $51 to $389 a year. At $74/yr, it runs about $25 a year cheaper than the class median of $99, and it is about $23 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $120/yr, the Danby DAC080B7IWDB-6 uses 38% less energy.
What drives its running cost
At 8000 BTU/hr, the Danby DAC080B7IWDB-6 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. Its CEER of 15, above 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 Danby DAC080B7IWDB-6 cheap to run?
Yes. Its $74/yr running cost puts it at rank #51 of 404, below what most room air conditioner models we track cost to run.
How much does the Danby DAC080B7IWDB-6 cost per month?
About $6.19 a month, which is the $74 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: 400 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $74 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Danby DAC080B7IWDB-6 for its size?
85th 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.
