What a humidifier costs here
Across 5 plans priced in Florida, a humidifier adds $26.28 to $32.08 a year — $2.19 to $2.67 a month. The median plan puts a humidifier at $28.56 a year.
Cheapest for a humidifier: RS Residential Electric, Jacksonville Electric Authority. Dearest: RTR-1 Residential Service TOU, Florida Power & Light Co..
Those 200 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 200 kWh a year across 39 sampled homes that run one, 1.45× the national 139 kWh. The middle half spans 14 kWh to 319 kWh, so a humidifier varies by 305 kWh between one household and another.
Portable and whole-home humidifiers. That average covers homes with a humidifier — 6% of homes here, against 24% nationally.
That makes a humidifier about 1% of the electricity a Florida home uses. The remaining 13,789 kWh is what a humidifier 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, $26.28; Florida Power & Light Co., $28.56.
Florida Power & Light Co. charges $2.28 a year more than Jacksonville Electric Authority on RS Residential Electric for the same 200 kWh.
