Summer brings intense heat and humidity—putting your cooling system under constant strain. However, a few adjustments can significantly reduce energy use without sacrificing comfort. Here are 14 practical ways to stay cool and save money this summer.
Set Thermostats for Efficiency
- Set to 78°F when home and increase it when away
- Each degree higher can reduce cooling costs by 2–3%
- Setting temperatures much lower than 78°F dramatically increases energy use.
- Use a programmable or smart thermostat
Set Multiple Thermostats the Same
- Keep thermostats at the same setting, it prevents one unit from overworking or sitting idle
- Helps balance cooling throughout the home
Keep Fans Set to AUTO
- Use AUTO so it only runs during cooling cycles
- If you run the fan continuously, it increases energy use
Change Air Filters Monthly
- Replace filters every 30 days. Dirty air filters restrict air flow and force systems to work harder.
- Use thin fiberglass filters
Block Heat from Sun
- Close blinds or curtains during peak afternoon hours, focusing on south- and west-facing windows
Use Ceiling Fans to Feel Cooler
- Use fans in occupied rooms and turn them off when you leave
Seal Air Leaks Around Doors and Windows
- Check for gaps/drafts. Look for light penetrating around the door
- Add weatherstripping or caulk where needed
Check Attic Access Points
- Make sure attic doors or pull-down stairs close tightly
- Consider installing an attic tent or cover
Keep Supply Vents and Returns Clear
- Keep vents fully open
- Move furniture away from returns
Open Interior Doors for Better Circulation
- Keep doors open to allow even cooling, it prevents hot and cold spots
Make Sure Your Outdoor Unit Is Running
- Confirm the outdoor compressor/condenser is running
- If not, the system needs attention
Schedule a Cooling System Check-Up
- Clean coils and check refrigerant levels
- Ensure proper airflow and operation
- Do this in the spring before heat intensifies
Avoid Using Heat-Producing Appliances During the Day
- Run dryers in the early morning or late evening
- Less indoor heat reduces cooling demand
- Avoid stove/oven use during peak afternoon hours and use grills, microwaves, or slow cookers instead
Optimize Pool Pump Run Time
- Avoid running 24/7
- Run during off-peak hours or overnight
- Variable-speed pumps can reduce energy use
