How To Prevent Emergency AC Repairs During Peak Summer

Summers in the Dallas–Fort Worth Metroplex can be downright brutal. When temperatures soar into the triple digits, your air conditioner isn’t just a comfort—it’s a necessity. But nothing’s worse than your AC system breaking down on one of the hottest days of the year. Emergency repairs can be stressful, costly, and inconvenient, especially when technicians across the area are swamped with service calls. Fortunately, most AC emergencies can be prevented with the right maintenance and care. At Texas Air Authorities, we’ve spent over two decades keeping our neighbors in Arlington, Fort Worth, and the surrounding areas cool, comfortable, and worry-free. In this guide, we’ll share how to keep your AC running smoothly all summer long—so you can avoid those dreaded emergency breakdowns.

1. Schedule Preventive Maintenance Before the Heat Hits

The best way to prevent an AC emergency is to catch problems early—before they turn into major breakdowns. Regular maintenance is your first line of defense. When you schedule a tune-up with Texas Air Authorities, our NATE-certified technicians perform a thorough inspection of your entire cooling system. We check refrigerant levels, clean the coils, test electrical connections, lubricate moving parts, and make sure your system is running safely and efficiently. Routine maintenance helps:

1. Extend the lifespan of your AC system
2. Improve energy efficiency and reduce your electric bills
3. Detect and fix small issues before they cause a breakdown
4. Keep your warranty valid

2. Change or Clean Your Air Filters Regularly

Dirty air filters are one of the most common causes of AC trouble—and one of the easiest to prevent. When your filter gets clogged with dust and debris, it restricts airflow through your system. That makes your air conditioner work harder than it should, leading to overheating, frozen coils, or even compressor failure. To prevent problems:

1. Check your air filter every month during summer.
2. Replace it every 1–3 months, depending on usage and indoor air quality.
3. If you have pets or allergies, consider upgrading to a high-efficiency pleated filter for better airflow and cleaner indoor air.

These small, inexpensive tasks can save you hundreds—or even thousands—of dollars in repair costs.

3. Keep the Outdoor Unit Clean and Clear

Your outdoor condenser unit plays a critical role in releasing heat from your home. If it’s blocked by dirt, leaves, grass clippings, or other debris, it can’t do its job efficiently—and that strain can cause the system to overheat or shut down. Here’s what you can do:

1. Turn off the power to your AC system.
2. Remove any debris or vegetation from around the condenser.
3. Use a garden hose (on low pressure) to gently rinse off the fins and remove dirt buildup.
4. Make sure there’s at least two feet of clearance around the unit for proper airflow.

If the condenser coils are heavily caked with grime or hard to access, our team can perform a professional coil cleaning as part of your seasonal maintenance service.

4. Don’t Ignore Unusual Noises or Weak Airflow

Strange sounds—like grinding, rattling, or hissing—are often early warning signs of trouble. Likewise, if you notice weak airflow, warm air from vents, or uneven cooling, your system might already be struggling. Many homeowners ignore these warning signs until the AC stops working completely, but addressing them early can prevent an expensive emergency. Common causes include:

1. Loose fan belts
2. Low refrigerant
3. Failing capacitors or motors
4. Leaky ducts

If you notice anything unusual, call Texas Air Authorities right away. We offer same-day appointments and fast diagnostics to catch and fix issues before they spiral into bigger problems.

5. Optimize Your Thermostat Settings

Your thermostat plays a bigger role in your AC’s health than you might think. Running your system nonstop at very low temperatures can wear it out faster. To reduce strain on your AC during peak summer:

1. Set your thermostat between 75°F and 78°F when you’re home.
2. Raise the temperature a few degrees when you’re away.
3. Use a programmable or smart thermostat to automatically adjust temperatures based on your schedule.

This not only prevents overworking your system but also helps reduce your monthly energy bills. If your thermostat is outdated or inaccurate, our technicians can recommend and install a modern, energy-efficient model that gives you better control and comfort.

6. Inspect and Seal Your Ductwork

Leaky ducts can cause your AC to work much harder than it should. Up to 30% of cooled air can be lost through holes or gaps in ductwork, forcing your system to run longer and increasing wear and tear. Professional duct inspection and sealing can:

1. Improve airflow and cooling performance
2. Reduce energy consumption
3. Prevent system strain and overheating

Texas Air Authorities offers duct inspection and repair services for homeowners across Arlington, Mansfield, Grand Prairie, and beyond. We’ll ensure your ducts are sealed tight and delivering cool air efficiently throughout your home.

7. Keep an Eye on Refrigerant Levels

Low refrigerant doesn’t just affect cooling—it can cause your evaporator coils to freeze and lead to a full system shutdown. Unfortunately, refrigerant doesn’t get “used up” naturally; if your levels are low, you likely have a leak. Only a certified HVAC technician can properly detect and repair refrigerant leaks. Our experts will:

1. Test your system for leaks
2. Recharge it with the correct refrigerant type
3. Verify the system’s performance and pressure levels

Ignoring a refrigerant issue can cause major compressor damage—and that’s one of the most expensive repairs in HVAC.

8. Use Ceiling Fans to Reduce AC Strain

Ceiling fans don’t lower the temperature, but they help circulate cool air more efficiently, allowing you to raise your thermostat by a few degrees without sacrificing comfort. During summer, make sure your ceiling fans are set to spin counterclockwise, pushing cool air downward. This simple trick lightens your AC’s workload and keeps your home feeling breezy and comfortable.
