As spring temperatures climb here in Lewisville, TX, it’s normal for cooling bills to climb right along with them. Air conditioners already account for a big portion of energy use in North Texas homes, but the good news is you don’t need a new HVAC system to see real savings. With a few smart adjustments, you can stay comfortable while keeping energy costs under control.

Below are practical, HVAC-friendly ways to improve efficiency and cut cooling expenses—perfect for homeowners across Lewisville, Flower Mound, Carrollton, Coppell, and the North Dallas suburbs.

Schedule Your HVAC Maintenance Before Summer

Spring is the ideal time to schedule an HVAC tune-up with a trusted local HVAC company like Select Air Conditioning & Heating. By beating the summer rush, you ensure your system is ready for heavy use and reduce the risk of mid-season breakdowns.

During a tune-up, your technician will check refrigerant levels, clean coils, tighten electrical components, verify system controls, and remove debris. Skipping routine maintenance forces your AC to work harder, increasing wear and pushing up your cooling bills.

Check the Condition of Your Ductwork

Your ductwork has a big impact on HVAC efficiency. Leaky or damaged ductwork can let up to a third of your cooled air escape into attics or crawl spaces—common in older Lewisville-area homes. That means your AC has to run longer to cool your living space.

Scheduling duct sealing or ductwork replacement can improve airflow, reduce wasted energy, and help your AC operate at peak performance.

Optimize Your Thermostat Settings

Small thermostat adjustments can lead to noticeable savings. Try keeping your home around 78°F when you're home and increasing it to about 85°F when you’re away.

Upgrading to a smart thermostat is a great way to improve comfort and efficiency. Smart thermostats learn your schedule, adjust temperatures automatically, and provide energy reports that show where you can conserve.

Use Ceiling Fans to Stay Comfortable

Ceiling fans improve airflow and help rooms feel cooler, even when you raise your thermostat a few degrees. For maximum benefit, make sure the fan blades spin counterclockwise during warmer months.

Remember—fans cool people, not rooms—so turn them off when you leave to avoid wasted energy.

Add Heat-Blocking Window Coverings

North Texas sun can heat up your home quickly. Installing blinds, reflective shades, or light-colored curtains helps prevent heat gain, especially on south- and west-facing windows.

Closing window coverings during the afternoon keeps indoor temperatures steadier and reduces stress on your air conditioner.

Seal Gaps and Leaks Around Your Home

Small gaps around windows and doors allow hot outdoor air to sneak inside while your cooled indoor air escapes. Use caulk for window frames, add weatherstripping to exterior doors, and seal attic or crawlspace openings with foam insulation.

These simple upgrades boost indoor comfort and improve overall HVAC efficiency.

Be Smart About Heat-Producing Appliances

Ovens, dishwashers, dryers, and other heat-producing appliances warm up your home more than you might expect. That extra heat makes your AC work harder—especially on warm Texas afternoons.

Try running these appliances early or late in the day. On hot days, grilling outdoors is a smart way to keep indoor temps down. Also, run bathroom exhaust fans after showers to reduce humidity, making your AC’s job easier.

Switch to Cooler, More Efficient Lighting

Traditional incandescent bulbs give off a lot of heat. Switching to LED lighting reduces indoor warmth and energy use, helping your AC keep your home comfortable without extra strain.

Keep Air Filters Clean

Dirty air filters restrict airflow and are one of the most common causes of poor AC performance. Replace filters every one to three months—more often during the spring and summer when your HVAC system works harder.
