Stay Cool for Less: Energy-Saving Moves for Summer
Practical ways to cut your summer cooling bill without sweating it out: thermostat habits, quick fixes, and the upgrades that actually pay off.
Cooling is usually the biggest piece of a summer electric bill, which makes it the easiest place to save. None of this means being uncomfortable. It's about cooling smarter, not less.

Free moves you can make today
- Nudge the thermostat up a few degrees when you're out or asleep. A small, steady setback adds up over a hot month, and you won't feel it while you're away.
- Close the blinds on the sunny side during the day. Blocking direct sun is one of the most effective free things you can do.
- Run ceiling fans, set counter-clockwise in summer. Fans cool people, not rooms, so turn them off when you leave. While you're there, they let you set the thermostat higher without feeling warmer.
- Cook and run the dishwasher or dryer in the evening when it's cooler, so you're not fighting your own appliances for cool air at peak heat.
The cheap upgrade with the biggest payoff
A smart or programmable thermostat handles the setbacks for you. It cools the house before you wake or get home and eases off when you don't need it. It's the rare upgrade that improves comfort and lowers the bill at the same time. See our smart-home guide.
Low-cost fixes worth doing
- Seal the leaks. Weatherstripping around doors and caulk around windows keep the cool air you paid for from sneaking out. One weekend afternoon, a few dollars of materials.
- Change the AC filter. A clogged filter makes the system work harder and run longer. Check it monthly in summer and swap it when it's dirty.
- Switch to LED bulbs. Old incandescent bulbs throw off real heat. LEDs run cool and use a fraction of the power.
Talk to your utility
A lot of electric utilities offer budget billing to smooth out summer spikes, plus rebates on efficient thermostats and AC units, and assistance programs for seniors and qualifying households. A five-minute call can turn up savings you'd never spot otherwise. Same idea as our bill checklist.
When to call a pro
If your system runs nonstop and still can't keep up, or your bills jumped without a change in habits, it might be low on refrigerant or simply aging out. A seasonal tune-up costs far less than an emergency replacement in July, so book it in spring before the rush.
Common questions
What thermostat setting saves the most in summer?
There's no magic number. The savings come from setting it a few degrees higher when you're asleep or away, consistently. A programmable or smart thermostat does it automatically so you don't have to remember.
Do ceiling fans actually lower the temperature?
They don't cool the air. They cool you, by moving air across your skin, which lets you set the thermostat a little higher and feel the same. So turn fans off in empty rooms to avoid wasting power.
