10 Ways to Lower Your Energy Bill This Summer

Oklahoma summers mean high AC bills. From thermostat settings to ductwork improvements, here are proven strategies to keep your home cool without breaking the bank.

· March 1, 2026· 2 min read

Oklahoma summers are no joke. When temperatures stay above 90 for weeks at a time, your air conditioner runs almost constantly. Here are 10 practical strategies to cut costs without sacrificing comfort.

1

1. Set Your Thermostat to 78 Degrees When Home

The Department of Energy recommends 78 degrees as the optimal balance between comfort and efficiency. Every degree lower increases energy consumption by roughly 3%.

2

2. Use a Programmable or Smart Thermostat

Let your home warm up while you're at work and cool back down 30 minutes before you return. A smart thermostat can do this automatically and pay for itself in one season.

3

3. Replace Your Air Filter Monthly

A clogged filter restricts airflow and forces your system to work harder. In summer, check and replace your filter every 30 days, especially if you have pets.

4

4. Seal Duct Leaks

The EPA estimates that 20-30% of conditioned air is lost through duct leaks. Have your ductwork inspected and sealed by a professional.

5

5. Use Ceiling Fans Correctly

Ceiling fans create a wind-chill effect that makes you feel cooler. Run them counterclockwise in summer. Turn them off when you leave the room — fans cool people, not spaces.

6

6. Block Solar Heat Gain

Close blinds and curtains on south and west-facing windows during the hottest part of the day. Cellular shades can reduce solar heat gain by up to 77%.

7

7. Cook Outdoors or Use the Microwave

Your oven adds significant heat to your home. Grill outside or use countertop appliances on hot days to reduce the load on your AC.

8

8. Schedule a Professional Tune-Up

A system running with dirty coils and low refrigerant uses significantly more energy than a properly maintained one.

9

9. Add Attic Insulation

Heat enters your home primarily through the roof. If your attic has less than 12 inches of insulation, adding more is one of the highest-ROI improvements you can make.

10

10. Consider a Variable-Speed System

If your AC is over 12 years old, upgrading to a variable-speed system with a 16+ SEER rating can cut your cooling costs by 30-50%.
