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
