Energy Saving Tips for Summer That Really Work

Set Your Thermostat Efficiently

Your thermostat setting has one of the biggest impacts on energy consumption.

For most homes, keeping the thermostat around 78°F (26°C) while you’re home and slightly higher when you’re away can reduce cooling costs without sacrificing comfort.

Smart thermostats make this even easier by automatically adjusting temperatures based on your schedule.

Use Ceiling Fans Correctly

Ceiling fans don’t lower room temperature, but they create a cooling breeze that makes you feel more comfortable.

During summer:

• Set fans to rotate counterclockwise.
• Turn them off when leaving a room.
• Use them alongside air conditioning instead of replacing it completely.

This allows you to raise the thermostat by a few degrees while maintaining comfort.

Close Curtains and Blinds During Peak Sunlight

Direct sunlight significantly increases indoor temperatures.

Keep blinds, curtains, or blackout shades closed during the hottest part of the day, especially on south- and west-facing windows.

This simple habit reduces solar heat gain and helps your air conditioner work less.

Improve Your Air Conditioning Efficiency

Your air conditioner is usually the largest energy consumer during summer.

Proper maintenance keeps it operating efficiently.

Replace Air Filters Regularly

Dirty filters restrict airflow and force your cooling system to work harder.

Check filters every month during summer and replace them as needed.

Benefits include:

• Better airflow
• Lower energy use
• Improved indoor air quality
• Longer HVAC lifespan

Schedule Annual HVAC Maintenance

Professional maintenance helps identify worn components before they become expensive problems.

Technicians typically inspect:

Routine servicing improves both efficiency and reliability.

Keep Outdoor Units Clear

Leaves, grass, and debris around outdoor condenser units reduce airflow.

Maintain at least two feet of open space around the unit for proper ventilation.

Seal Air Leaks Around Your Home

Cool air escaping through cracks forces your HVAC system to run longer.

Inspect common problem areas, including:

• Windows
• Doors
• Attics
• Crawl spaces
• Utility openings

Weatherstripping and caulking are inexpensive upgrades that often produce noticeable energy savings.

Upgrade Your Home Insulation

Insulation isn’t only valuable during winter.

A well-insulated home keeps cool air inside during summer while preventing outdoor heat from entering.

Focus on:

• Attics
• Exterior walls
• Basement ceilings
• Garage ceilings

Improved insulation helps maintain consistent indoor temperatures year-round.
