How much does it cost to run an air conditioner in Nevada?

Data checked October 2026

Short answer

A 3-ton central air conditioner in Nevada costs about $107.46 in July and $398 a year at 13.36¢/kWh; an 8,000 BTU window unit about $22.42 in July.

Nevada pays 13.36¢/kWh on average for Jan–Aug 2026 — 27% below the U.S. average of 18.19¢, the 46th most expensive of the 50 states and DC.
Nevada averages 1,921 cooling degree days a year against 1,216 nationally (NOAA), so we estimate 1,185 full-load cooling hours — 10.3 a day in July.
A new 3-ton split system sold for Nevada must reach at least SEER2 14.3 (DOE southwest region); it draws about 2.52 kW on average and $0.34 an hour.
Moving up to the ENERGY STAR average of about SEER2 17 would cut the yearly bill to $335 — $63.29 a year less.
The average Nevada home used 870 kWh a month in 2025; this system adds 804 kWh in July.

1 ton = 12,000 BTU/h. It's in the outdoor unit's model number: 24 = 2 ton, 36 = 3 ton, 48 = 4 ton.

Efficiency (SEER2)

Exact SEER2

New split systems sold for Nevada must be at least SEER2 14.3. SEER2 is on the EnergyGuide label or AHRI certificate.

How much it runs

Run time

1,185 full-load hours a year: DOE's 750-hour national basis × 1,921 cooling degree days in Nevada ÷ 1,216 U.S.

On a 95°F afternoon

SEER2 is a season average. At the hottest hours a typical 3-ton system (EER2 11.49) draws about 3.1 kW — $0.42 an hour.

How to cut it

Raise the thermostat a few degrees and run a ceiling fan instead — an ENERGY STAR fan uses about 35 W on high.
Change the filter and keep the outdoor coil clear of leaves and grass so the system moves heat as rated.
Close blinds on sun-facing windows in the afternoon, when cooling hours peak.

How this was worked out

DOE's room-AC test assumes 750 full-load hours a year for a typical U.S. home. We scale it by Nevada's population-weighted cooling degree days (1,921 ÷ 1,216) and spread it over the months the same way: 1,185 hours a year. Your thermostat setting and insulation move this a lot — switch the calculator to your own hours if you know them.

3 tons = 36,000 BTU/h ÷ SEER2 14.3 = 2,517 W. × 1,185 h = 2,983 kWh × 13.36¢ = $398.
