Summer bills vary by region, home type, insulation, air conditioning system, humidity, and time spent at home.
This guide focuses on practical comfort-first steps.
Thermostat
Small changes can reduce cooling load without sacrificing all comfort.
Shading
Curtains, blinds, and exterior shade reduce heat gain.
Fans
Fans improve comfort but cool people, not rooms.
Filters
Clean filters help airflow in central systems.
Humidity
Humidity affects comfort and dehumidifier use.
Timing
Time-based rates may reward shifting flexible use.
Reduce heat gain first
Close curtains or blinds during hot sunny periods, especially on south- and west-facing windows. Exterior shading can be even more effective where practical.
Avoid adding indoor heat during the hottest parts of the day. Ovens, dryers, and long hot showers can add heat and humidity.
Use fans correctly
Fans make people feel cooler by moving air. They do not lower the room temperature, so turn them off in empty rooms.
Ceiling fan direction and speed should be adjusted according to manufacturer guidance.
Maintain cooling equipment
Clean or replace filters as appropriate, keep vents clear, and do not block outdoor units. If equipment is failing, plan service before a heat wave if possible.
Summer energy actions
| Action | Cost level | Why it helps |
|---|---|---|
| Close blinds during hot sun | Free | Reduces heat gain |
| Use fans in occupied rooms | Low | Improves comfort |
| Raise thermostat slightly | Free | Reduces cooling load |
| Clean filters | Low | Improves airflow |
| Avoid oven/dryer at peak heat | Free | Reduces indoor heat |
| Service failing equipment | Moderate | Prevents inefficient operation |
Summer cooling checklist
- Block direct sun during hot periods.
- Use fans only where people are present.
- Keep vents and filters clear.
- Avoid adding heat indoors during peak heat.
- Check thermostat schedules.
- Compare usage with last summer.
- Plan repairs before emergency heat events where possible.

FAQ
Do fans reduce electricity use?
Fans use less energy than air conditioning, but they cool people rather than rooms. Turn them off when rooms are empty.
Can curtains really help?
Yes, shading sunny windows can reduce heat gain and improve comfort.
Why did my summer bill rise?
Air conditioning, humidity, more time at home, pool pumps, appliances, and heat waves can increase usage.
