⚡ How Much Does Your AC Cost to Run per Month?
Calculate how much electricity your AC uses per day, month, and 3-month season — and how much that costs on your local tariff. Compare Inverter vs Non-Inverter, in USD, INR, AED, SAR, EUR, GBP or AUD.

What Air Conditioning Really Costs in New York
New York’s cooling season is short but expensive. The state average electricity rate in 2026 is about $0.30 per kWh — and if you’re a Con Edison customer in New York City or Westchester, your all-in rate (supply + delivery) is often $0.30–$0.35/kWh, among the highest in the country. Upstate customers on National Grid or NYSEG typically pay considerably less, around $0.16–$0.22/kWh. The calculator above defaults to the state average; enter your own rate from your bill’s supply + delivery total for an accurate figure.
New York Utility Rates at a Glance (2026)
| Utility | Service Area | Typical All-In Rate |
|---|---|---|
| Con Edison | NYC (Manhattan, Bronx, Brooklyn, Queens, Staten Island), Westchester | 30 – 35 ¢/kWh |
| PSEG Long Island | Nassau & Suffolk Counties | 22 – 26 ¢/kWh |
| National Grid | Upstate: Buffalo, Syracuse, Albany | 16 – 20 ¢/kWh |
| NYSEG | Southern Tier, Finger Lakes | 16 – 22 ¢/kWh |
| Central Hudson | Mid-Hudson Valley | 18 – 24 ¢/kWh |
The Window-Unit Capital of America
Unlike the rest of the Sun Belt, most New York City apartments cool with window units and portable ACs rather than central systems. That changes the math:
- A typical 10,000 BTU window unit draws 900–1,200 watts. At Con Ed’s ~32¢/kWh, running it 8 hours a day costs roughly $70–$95/month per room.
- Three window units in a NYC apartment can out-cost a whole-house central system in Atlanta — purely because of the electricity rate.
- Newer U-shaped inverter window units use 30–35% less energy than the decade-old sliders many apartments still run. At NYC rates the upgrade often pays for itself in one or two summers — model it with the Inverter comparison in the calculator above.
If your building has ductless mini-splits (increasingly common in brownstone renovations), those inverter systems are the most efficient cooling per kWh available in the city.
Trimming a New York Summer Bill
- Con Edison’s TOU and Smart Usage Rewards plans reward shifting cooling out of the 2–6pm summer peak — pre-cool your apartment in the late morning.
- Seal around window units with foam side panels and top gaskets; a leaky install can waste 10–15% of the cooling you’re paying premium rates for.
- NYSERDA offers rebates on high-efficiency room ACs and heat pumps — check current offers before replacing an old unit.
- In pre-war buildings with radiators, insulate/reflect behind them; heat soaking out of steam risers in July makes your AC fight your own heating system.
Frequently Asked Questions — New York
How much does a window AC cost to run in NYC? At Con Edison rates, a mid-size unit costs $2–$3.50 per 8-hour day — typically $70–$95/month. Use the calculator above with the “Custom wattage” option for your unit’s exact draw.
Why is Con Edison so expensive? NYC’s delivery infrastructure (underground network, dense grid) roughly doubles the delivered cost of each kWh compared with upstate overhead lines.
Is central air worth adding to a New York home? Upstate at National Grid rates, often yes. In the city, ductless mini-splits usually beat both window units (efficiency) and ducted central (installation cost) for most apartments and row houses.
