What the TCL T32DC3S costs to run
ENERGY STAR certifies the TCL T32DC3S at 343 kWh/yr, cheaper than most models in its category to run for its category.
The $64 figure above uses the simple average of all 51 published state rates. Pick your state for the real number.
TCL T32DC3S against the category
That's 9.3% below the dehumidifier category average of 378 kWh/yr, and ranks 281 of 546 certified dehumidifiers for annual running cost, 1 being cheapest. The category average comes from every dehumidifier ENERGY STAR currently certifies (546 models), not an outside benchmark, about $7/year below that average at the national rate. See the methodology page.
What sits beside it in the ranking
TCL T32DC9R ($64/yr, 343 kWh/yr) costs a little more to run than the TCL T32DC3S. TCL H32D44W ($64/yr, 343 kWh/yr) costs a little less.
Same brand, different models
TCL makes 16 ENERGY STAR certified dehumidifiers; this one ranks 6 of 16 for running cost, between the brand's cheapest, the T25DC9R at $53/yr, and its priciest, the T50DC9SPB at $100/yr.
Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for dehumidifiers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Is it worth replacing?
The TCL T32DC3S is already efficient for its category at $64/year. If you're shopping and comparing options, this is roughly what a well-chosen new dehumidifier costs to run.
Worth comparing a few current certified models before deciding.
Protecting what you have
Whether or not the TCL T32DC3S ever needs replacing, a repair is the more common failure for a dehumidifier, one a protection plan budgets for ahead of time.
Sourcing
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. At rank 281 of 546 for running cost, see the dehumidifier category page for the rest of the field, or the guide to how much your state matters.
