Model
Frigidaire FHDD2234W1
Rank #161 means 160 of the 519 dehumidifier models we track cost less to run each year; the 6th efficiency percentile means it uses less energy for its size than 6% of those models.
What does the Frigidaire FHDD2234W1 cost to run per year?
At $53 a year to run, the Frigidaire FHDD2234W1 runs cheaper than most models in its class, ranking #161 of 519 dehumidifier models we track. Once capacity is factored in, its efficiency percentile of 6 is among the lowest in its class. At a IEF of 1.7, its integrated energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Whirlpool WHAD251AW at $53/yr runs a little cheaper and the Midea MDUDA-25AEN8-BB0F at $53/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A dehumidifier typically stays in service for somewhere around 8 years; over that span, the Frigidaire FHDD2234W1's $53/yr adds up to roughly $424 in electricity alone, before purchase price or repairs.
By the numbers
The Frigidaire FHDD2234W1 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 $53/yr, here is what the Frigidaire FHDD2234W1 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Frigidaire FHDD2234W1 costs about $530. That is roughly $110 less than the class median, which would run closer to $640 over the same ten years.
How the Frigidaire FHDD2234W1 compares
The dehumidifier class we track runs from $19 to $521 a year. At $53/yr, it runs about $11 a year cheaper than the class median of $64, and it is about $34 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 22.57 pints/day, the Frigidaire FHDD2234W1 is a small dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, 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 IEF of 1.7, below the class median of 2.01, reflects integrated energy factor: 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.
- Integrated Energy Factor (IEF). Two dehumidifiers rated for the same pints per day can carry very different IEF figures, and IEF is what actually separates their running costs.
- Water removal capacity (pints/day). Pints-per-day rating scales with the space it is built for, and that rating is the first driver of how much power the compressor needs.
- Humidistat accuracy. How tightly a humidistat holds its target humidity determines how much of the day the compressor actually runs, on top of the unit's rated capacity and IEF.
Common questions
Is the Frigidaire FHDD2234W1 cheap to run?
Yes, relatively. At $53 a year it ranks #161 of 519 dehumidifier models we track, in the cheaper part of its class to run.
How much does the Frigidaire FHDD2234W1 cost per month?
Roughly $4.38/mo, spreading the $53/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 283 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $53 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Frigidaire FHDD2234W1 for its size?
6th percentile once size is factored in, a fairly typical result for the class.
