With Florida heat and humidity running almost year-round, cooling costs can become one of the biggest household expenses. Here are practical ways homeowners can stay comfortable while lowering monthly energy bills.
1. Raise the Thermostat a Few Degrees
Setting your thermostat just 2–3 degrees higher can make a noticeable difference.
Recommended when home: 76–78°F
Recommended when away: 80–82°F
Using ceiling fans helps rooms feel cooler without overworking the AC.
2. Replace Air Filters Regularly
Dirty filters force your HVAC system to work harder.
Change filters every 1–3 months
Homes with pets may need more frequent changes
A clean filter improves airflow and efficiency.
3. Seal Air Leaks
Cool air often escapes through:
doors
windows
attic access points
garage connections
Simple weather stripping or caulking can reduce wasted energy quickly.
4. Keep Humidity Under Control
Florida humidity makes homes feel hotter than they actually are.
Tips:
Use bathroom exhaust fans
Run kitchen vents while cooking
Consider a whole-home dehumidifier
Keep indoor humidity around 45–55%
Lower humidity helps the AC cool more efficiently.
5. Use Blackout Curtains or Solar Shades
Direct sunlight can dramatically increase indoor temperatures.
Closing blinds during the hottest part of the day can:
reduce indoor heat gain
ease AC strain
lower afternoon cooling costs
South- and west-facing windows matter most.
6. Schedule HVAC Maintenance
An annual tune-up helps systems run efficiently before peak summer heat arrives.
A technician can:
clean coils
check refrigerant levels
inspect ductwork
improve airflow
Preventive maintenance can also extend the life of the system.
7. Avoid Heat-Producing Appliances During Peak Hours
Ovens, dryers, and dishwashers create extra indoor heat.
Try using them:
early morning
later evening
This keeps the AC from fighting additional heat during the hottest hours.
8. Upgrade to a Smart Thermostat
Smart thermostats automatically adjust temperatures based on your schedule.
Benefits include:
less wasted cooling
remote control from your phone
energy usage tracking
Many Florida utility companies also offer rebates.
9. Improve Attic Insulation
Poor attic insulation allows heat to pour into the home.
Proper insulation:
keeps cool air inside
reduces HVAC workload
improves overall comfort
This is especially important in older Florida homes.
10. Use Ceiling Fans Correctly
Fans cool people — not rooms.
In summer:
blades should rotate counterclockwise
this pushes air downward for a cooling effect
Turn fans off when leaving a room to save electricity.
Bonus Tip: Check Your Water Heater Temperature
Many Florida homeowners keep water heaters hotter than necessary.
Setting it to 120°F can reduce energy use while still providing plenty of hot water.
