AC repair
When the house is getting warmer, you need a calm diagnosis and a clear next step.
North Texas cooling calls often involve failed capacitors, refrigerant leaks, clogged drain lines, frozen evaporator coils, blower motor failures, thermostat issues, compressor problems, and dirty condenser coils.
Emergency guidance: no cooling during extreme heat, water near electrical components, burning smells, or sparking equipment should be handled quickly.
Repair examples
Repair cost depends on the failed component, system accessibility, equipment age, and warranty status. Cornerstone provides options before work begins.

Ice is a symptom. Airflow, filters, coils, refrigerant indicators, and run conditions all need review.
Clogged drains and float switches can shut systems down to reduce water damage risk.
