North Texas summers are long and hot, which puts steady stress on a home. This checklist covers the routine tasks that help prevent expensive breakdowns during peak cooling season.
Air conditioning. Replace or clean filters every one to three months, clear debris around the outdoor unit, and schedule a professional tune-up before the first heat wave. A struggling system costs more to run and fails sooner.
Attic and insulation. Check attic ventilation and insulation. Poor airflow traps heat and makes the AC work harder. Seal obvious air leaks around windows and doors.
Water and irrigation. Inspect sprinkler systems for leaks and adjust run times for heat. Check for slow leaks under sinks and around water heaters.
Exterior. Trim branches away from the roof and lines, and inspect for storm damage after hail. Clean gutters so summer storms drain properly.
FAQ
How often should I change the HVAC filter? Every one to three months during heavy summer use; check it monthly.
Can I do this myself? Basic tasks like filters and gutters are DIY. Electrical, refrigerant and roof work should be left to licensed professionals.
