What a dehumidifier costs here
Across 5 plans priced in Florida, a dehumidifier adds $188.52 to $229.81 a year — $15.71 to $19.15 a month. The median plan puts a dehumidifier at $204.72 a year.
Cheapest for a dehumidifier: RS Residential Electric, Jacksonville Electric Authority. Dearest: RTR-1 Residential Service TOU, Florida Power & Light Co..
Those 1,436 kWh are billed at 13.1¢–16.0¢, against a 13.4¢ whole-bill average on the median plan: they land in the last tier the household reaches, so the average rate understates them by up to 2.6¢ per kWh.
What Florida homes use
EIA's 2020 residential survey found 1,436 kWh a year across 59 sampled homes that run one, 1.44× the national 999 kWh. The middle half spans 426 kWh to 1,985 kWh, so a dehumidifier varies by 1,559 kWh between one household and another.
Portable and whole-home dehumidifiers. That average covers homes with a dehumidifier — 8% of homes here, against 17% nationally.
That makes a dehumidifier about 10% of the electricity a Florida home uses. The remaining 12,554 kWh is what a dehumidifier is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
By provider
On each Florida provider's cheapest plan: Jacksonville Electric Authority, $188.52; Florida Power & Light Co., $204.72.
Florida Power & Light Co. charges $16.20 a year more than Jacksonville Electric Authority on RS Residential Electric for the same 1,436 kWh.
