15 energy saving tips for summer to cut costs and stay cool

Summer heat often brings a spike in energy use and electric bills, especially when air conditioners run around the clock. But staying cool doesn’t have to mean draining your budget. By following these practical energy saving tips for summer, you can cool your home, reduce your energy costs, and improve overall energy efficiency. 

Here are 15 ways to save energy and money this summer — without sacrificing comfort. 

1. Adjust your thermostat setting

Start with one of the easiest changes: your thermostat setting. Set it to 78 degrees Fahrenheit when you’re home, and increase it by seven to 10 degrees when you’re away. This small adjustment can cut cooling costs by up to 10 percent annually.

2. Install a smart thermostat

A smart thermostat can learn your schedule and automatically adjust the temperature to reduce waste. Many models let you control settings remotely from your phone, making it easier to optimize heating and cooling even when you’re not home.

3. Use ceiling fans strategically

Ceiling fans use far less energy than air conditioners and help distribute cool air evenly. But remember, fans cool people, not rooms, so turn them off when you leave.

4. Upgrade to an energy-efficient room air conditioner

If your room air conditioner is more than 10 years old, it may be time to replace it with an ENERGY STAR® certified model. These units use up to 15 percent less energy and can significantly reduce your electric bills.

5. Close curtains and blinds during the day

Block out warm air and direct sunlight by keeping blinds or curtains closed, especially on south- and west-facing windows. This reduces the amount of heat entering your home, helping your cooling system work more efficiently.

6. Seal leaks and insulate

Check for drafts around windows, doors, and ductwork. Proper insulation and sealing prevent cool air from escaping and warm air from entering, which lightens the load on your cooling system.

7. Clean or replace air filters regularly

Dirty filters restrict air flow and force your air conditioner to work harder. Clean or replace filters every one to three months during the summer to maintain peak energy efficiency.

8. Keep air vents clear

Ensure that air vents are not blocked by furniture, rugs, or curtains. Clear vents allow your cooling system to operate effectively, improving air circulation and comfort.

9. Use exhaust fans wisely

Turn on exhaust fans in the kitchen and bathroom to remove hot, humid air after cooking or showering. This helps keep the rest of the home cooler and reduces the need for additional cooling.

10. Cook smart to stay cool

Using the oven during the hottest part of the day can heat up your entire house. Opt for outdoor grilling, slow cookers, or microwaves to minimize indoor heat generation.

11. Use energy-efficient lighting

Incandescent bulbs emit heat. Switch to LED lighting, which uses less electricity and generates minimal heat, supporting your broader summer energy saving strategy.

12. Consider attic ventilation

An overheated attic can raise indoor temperatures. Install attic vents or fans to help expel hot air and lower the demand on your air conditioner.

13. Install window films or reflective coatings

Reflective films or low emissivity (Low-E) coatings on windows can block heat and UV rays, keeping interior spaces cooler and protecting furnishings from sun damage.

14. Schedule routine maintenance

Have a professional inspect and tune your cooling system before peak season. Routine maintenance improves energy efficiency and prolongs the life of your unit.

15. Shift energy use to off-peak hours

Run dishwashers, washing machines, and dryers early in the morning or late at night to avoid peak energy hours. This not only helps manage grid demand but may also lower your energy bills if your utility uses time-of-use pricing. 

Maximizing energy efficiency year-round 

While these energy saving tips for summer focus on cooling, many apply year-round to your overall heating and cooling strategy. Whether you’re adjusting your thermostat setting, using ceiling fans, or upgrading your room air conditioner, small changes can have a big impact over time. 

By staying mindful of how you cool your home and maintain airflow, you can keep indoor temperatures comfortable without overspending. And with rising energy costs across much of the country, there’s never been a better time to prioritize energy efficiency.
