Your Seasonal AC Repair & Maintenance Checklist for Texas Homes

In Texas, your air conditioner isn’t just a luxury—it’s a lifeline. With long, hot summers and high humidity, AC systems work harder here than in most parts of the country. To keep your home cool and your bills under control, seasonal maintenance is essential. This step-by-step checklist will help you stay ahead of breakdowns, extend your system’s life, and keep your family comfortable year-round.

Why Seasonal Maintenance Is a Must in Texas

According to the U.S. Department of Energy, regular AC maintenance can lower cooling costs by 15% and reduce the chance of breakdowns. For homeowners in Dallas, Mansfield, and other parts of North Texas, this means fewer emergencies during peak summer and longer-lasting equipment.

Spring: Prepare for the Cooling Season

Replace or Clean Filters

Start each season with a clean filter to ensure strong airflow. Dirty filters reduce efficiency and can even cause frozen coils.

Inspect the Outdoor Unit

Clear away leaves, dirt, and debris around your condenser. Make sure at least two feet of space surrounds the unit for proper airflow.

Schedule a Professional Tune-Up

Spring is the perfect time to schedule professional service before demand spikes. A technician can clean coils, check refrigerant levels, and test efficiency. Bless-It Air provides trusted Air Conditioning Repair in Dallas, TX and nearby cities like Wylie and Desoto.

Summer: Keep Your System Running Smoothly

Adjust Your Thermostat

Set your thermostat a few degrees higher when you’re not home. Smart thermostats can automate these adjustments, saving energy without sacrificing comfort.

Monitor Energy Bills

If your bills suddenly spike, it could be a sign your system is working too hard. Schedule Air Conditioning Repair in Mansfield, TX if you notice unusual changes.

Check for Ice on Coils

Ice buildup means something is wrong—usually restricted airflow or low refrigerant. Turn off the system and call a technician immediately.

Fall: End-of-Season Maintenance

Clean and Inspect Ducts

Leaky or dirty ducts reduce efficiency and worsen indoor air quality. A professional inspection can save money and improve comfort.

Seal Air Leaks

Use caulk or weatherstripping around windows and doors to prevent heat loss during cooler months. This step also helps when the AC is running.

Replace Filters Again

Even after peak cooling season, it’s wise to install fresh filters for winter air circulation.

Winter: Protect Your AC System

Run the System Occasionally

Turning the system on briefly during mild winter days helps keep parts lubricated and prevents components from seizing.

Cover the Outdoor Unit

If your AC won’t be in use for several months, consider covering the outdoor condenser to protect it from debris.

Plan Ahead for Spring Service

Winter is the ideal time to schedule your spring tune-up appointment so you’re ready before the first heatwave.

Extra Tips for Year-Round Efficiency

• Keep blinds and curtains closed during peak sun hours.

• Use ceiling fans to circulate cool air.

• Upgrade to high-efficiency filters or HEPA filters for better air quality.

• Install attic insulation to reduce strain on your AC system.

Signs You Shouldn’t Ignore

Even with regular maintenance, issues may arise. Call a professional if you notice:

• Warm air blowing from vents.

• Strange noises like grinding or hissing.

• Frequent on-and-off cycling.

• Weak airflow in certain rooms.

• Unexplained increases in energy bills.
