Energy Saving Tips for Texas Summers: Lower Your AC Bill

In Austin, your air conditioner accounts for 40–50% of your summer electricity bill. With temperatures regularly topping 100°F from June through September, that adds up fast. Here are practical, no-nonsense strategies to lower your cooling costs without suffering through the heat.

1. Set Your Thermostat — and Leave It Alone

The optimal setting for summer is 78°F when you're home, and 82–85°F when you're away. Each degree below 78 adds roughly 3–5% to your cooling cost. Cranking the thermostat down to 68° doesn't cool your home faster — it just makes the system run longer. Install a programmable or smart thermostat to automate these adjustments.

2. Use Ceiling Fans — Correctly

Ceiling fans cool people, not rooms. They create a wind-chill effect that can make you feel 4°F cooler. Set blades to spin counter-clockwise in summer (pushing air down). Turn them off when you leave the room — running a fan in an empty room wastes electricity.

3. Seal Air Leaks

Gaps around windows, doors, and electrical outlets let cool air escape. A $10 tube of caulk and some weatherstripping can reduce your cooling load by 10–15%. Pay special attention to attic hatches and recessed lighting — they're major leak points.

4. Close Blinds During the Day

South- and west-facing windows let in enormous amounts of heat. Close blinds or curtains during peak sun hours (11 AM–4 PM). Even better, install reflective window film or solar screens — they can reduce solar heat gain by up to 70%.

5. Schedule Annual AC Maintenance

A well-tuned AC uses 15–20% less energy than a neglected one. Our spring tune-up includes coil cleaning, refrigerant level checks, and airflow optimization. Call (512) 555-0142 to book your maintenance visit.
