How to Lower Your Energy Bills While Running Your AC in September

September 18, 20253 min read

September in Texas can be tricky. The mornings hint at cooler fall weather, but by midday, temperatures often climb back into the 90s. That means your air conditioner is still working hard—and your energy bills might show it. The good news? With a few smart strategies, you can stay cool without breaking the bank.

At LTX Air Services, we’ve helped countless Dallas–Fort Worth homeowners improve efficiency and cut costs. Here’s how you can lower your energy bills while keeping your home comfortable this September.

1. Schedule a Professional AC Tune-Up

A system that isn’t maintained has to work harder, which leads to higher utility bills. Seasonal AC maintenance ensures your system is cleaned, lubricated, and optimized for peak efficiency. Even a small issue—like a clogged filter or low refrigerant—can spike your energy usage.

💡 Pro Tip: Book your tune-up now before temperatures fully transition. This gives your system a performance boost while also preparing it for fall.

2. Replace or Clean Air Filters Regularly

Dirty air filters restrict airflow, making your system strain to cool your home. Changing your filters every 30–60 days is one of the simplest and most effective ways to reduce costs. Plus, clean filters improve indoor air quality, keeping your family healthier.

3. Use Ceiling Fans for Circulation

Running ceiling fans in occupied rooms allows you to raise your thermostat by a few degrees without sacrificing comfort. Fans don’t actually lower the temperature—they help circulate cool air more efficiently, easing the load on your AC.

4. Adjust Your Thermostat Strategically

Set your thermostat to around 76–78°F when you’re home and a bit higher when you’re away. For even more savings, consider a smart thermostat, which adjusts automatically and provides insight into your energy use. LTX Air Services offers smart thermostat integration with our installations.

5. Seal Air Leaks and Insulate

If cool air is escaping through gaps in doors, windows, or ductwork, your system will work harder than necessary. Have your ducts inspected and sealed—air duct cleaning and maintenance can prevent energy waste while also reducing allergens.

6. Limit Heat-Producing Activities During the Day

Using ovens, dryers, or heat-generating electronics in the hottest part of the day makes your AC run longer. Shift these tasks to mornings or evenings to reduce strain.

7. Consider an Energy-Efficient Upgrade

If your AC is over 10–15 years old, it may be costing you more in energy and repairs than it’s worth. Newer systems are designed to use less power while providing better cooling. Explore our AC installation services for energy-efficient upgrades tailored to your home.

Why September Is the Best Time for Maintenance

Think of September as a “shoulder season.” It’s the perfect time to get your system serviced—before the rush of fall heating calls and while your AC is still in use. A well-timed tune-up keeps your unit efficient now and ensures it transitions smoothly into cooler months.
