How to Prevent Your AC from Overheating This Summer

When the Texas sun starts to blaze, your air conditioner becomes your home’s best friend. But with triple-digit temps bearing down on the Dallas-Fort Worth Metroplex, your AC system works overtime—and that can lead to overheating. At Texas Air Authorities, we’ve seen it all, from burned-out compressors to total system shutdowns. Fortunately, with a little planning and routine care, you can help prevent overheating and avoid costly breakdowns this summer.

Here’s what every homeowner should know to keep their AC running cool and strong all season long.

1. Change Your Air Filter Regularly

This is the simplest—and most overlooked—step in protecting your AC system. A dirty air filter restricts airflow, making your unit work harder than it should. Over time, this added strain can lead to overheating and even compressor failure.

Tip from our techs: Check your filter monthly during peak cooling season. Replace it every 1–2 months, or more often if you have pets or allergies.

2. Keep the Outdoor Unit Clean and Clear

Your outdoor condenser unit needs room to breathe. If it’s surrounded by leaves, grass clippings, dirt, or debris, heat can’t escape properly—which causes the unit to overheat.

Make sure there’s at least 2 feet of clearance around the unit. Trim back shrubs, sweep away buildup, and give it a rinse with a garden hose if needed (just turn off the power first).

3. Schedule Annual AC Maintenance

Preventive maintenance is the best way to catch problems before they turn into full-blown failures. During a tune-up, a certified HVAC technician will clean components, check refrigerant levels, test electrical systems, and ensure everything is running efficiently.

At Texas Air Authorities, we offer same-day appointments and comprehensive inspections that help prevent overheating, extend your system’s lifespan, and maintain your warranty. Don’t skip it—it could be the difference between a cool home and a mid-July meltdown.

4. Use a Smart Thermostat

When temperatures hit the high 90s (or worse), it’s tempting to crank the thermostat way down—but that can stress your system. A smart thermostat can balance comfort with efficiency by learning your habits and automatically adjusting temps when you’re away or asleep.

Not only does this reduce the load on your AC, but it helps prevent overuse, which is a major factor in overheating. Plus, smart thermostats can alert you when something’s wrong—giving you time to act before real damage occurs.

5. Check Your Ductwork

Leaky or uninsulated ducts force your AC to work harder to cool your home. This extra effort can cause the unit to overheat, especially during peak usage. Sealing and insulating ducts can improve efficiency by up to 20%, according to Energy Star.

If you suspect airflow issues or uneven cooling in your home, let our techs take a look. We specialize in duct inspection and repair for all types of systems.

6. Avoid Blocking Vents

It might seem harmless, but blocking supply or return vents with furniture, rugs, or clutter can restrict airflow and contribute to overheating. Make sure all vents are open and unobstructed so your system can breathe and distribute air evenly.
