How to Lower Your Electric Bill This Summer in Redlands

May 30, 2025

If you’ve lived through a summer in Redlands, you know the heat isn’t just uncomfortable—it can also be expensive. With air conditioners working overtime, energy bills tend to spike between June and September. Fortunately, there are smart, affordable ways to stay cool without blowing your budget.

At Lasting Legacy Plumbing, Heating & Air, we help Inland Empire homeowners optimize their comfort and energy usage. Here are our top tips to lower your electric bill this summer while keeping your home comfortably cool.

1. Schedule a Professional, Meticulous AC Tune-Up

A well-maintained air conditioner performs more efficiently and uses less energy. Over time, dust, worn parts, and low refrigerant can cause your system to work harder than it should.

Why it matters:
A seasonal AC tune-up can improve airflow, reduce strain on the system, and identify small issues before they lead to costly repairs or energy waste.

Local tip:
Redlands homeowners should schedule a tune-up in late spring or early summer for best results. Learn more about our $79 AC Tune-Up Special here.

2. Raise Your Thermostat (Just a Little)

Every degree counts. Setting your thermostat just 2–3 degrees higher can noticeably reduce your monthly energy bill. Try aiming for 78°F when you're home, and 85°F when you're away.

Pro tip:
Install a programmable or smart thermostat to automate temperature settings and avoid overcooling when you're not home.

3. Seal and Insulate Problem Areas

Cool air escapes through cracks around doors, windows, and attic hatches. Redlands homes—especially older properties—often lose efficiency this way.

What to do:

♦ Seal leaks with caulk or weather stripping

♦ Add insulation to attics or garages

♦ Close blinds or curtains during peak heat hours

Bonus benefit:
You'll reduce cooling costs and make your home more comfortable year-round.

4. Replace Dirty Air Filters

A clogged air filter restricts airflow, making your system work harder to push out cool air.

Quick fix:
Check your air filter once a month and replace it every 30–90 days, especially during heavy use in the summer.

5. Use Fans Strategically

Ceiling and box fans help circulate air so you can feel cooler without dropping the thermostat.

Pro tip:
Make sure your ceiling fan is set to spin counterclockwise in the summer to create a wind-chill effect.

6. Avoid Peak Energy Hours When Possible

Southern California utility providers often charge more during peak hours, typically between 4 PM and 9 PM.

Energy-saving tips:

♦ Run laundry or dishwashers early in the morning or late at night

♦ Pre-cool your home before peak time, then rely on fans and closed blinds

7. Consider an HVAC System Upgrade

If your AC is more than 10–15 years old, it may be costing you more than it's saving. Newer HVAC systems are up to 30% more efficient and may qualify for rebates or tax credits.

Frequently Asked Questions: Lowering Your Electric Bill in Redlands

Is 78 degrees too high for indoor comfort in summer?

Not at all—78°F is recommended by the U.S. Department of Energy for energy efficiency during the summer. If that feels too warm, ceiling fans and light clothing can help you feel cooler at that temperature.

Do smart thermostats really save money?

Yes. Smart thermostats can learn your habits and automatically adjust settings to reduce cooling when you’re away from home. Many Redlands homeowners report noticeable savings after switching to a smart thermostat.

How often should I change my air filter in the summer?

During heavy AC use, you should change your air filter every 30 to 60 days. If you have pets, allergies, or an older system, check it more frequently.

What time of day is electricity cheapest in Redlands?

In most Southern California Edison and local utility service areas, off-peak hours—typically before 4 PM and after 9 PM—offer lower electricity rates. Try to run appliances during those times to cut costs.

Is it worth upgrading to a high-efficiency HVAC system?

If your system is over 10–15 years old, upgrading can significantly reduce your monthly energy usage. New ENERGY STAR® HVAC systems are more efficient and may qualify for rebates or tax credits in California.
