AC repair

Cooling repairs without the runaround.

When the house is getting warmer, you need a calm diagnosis and a clear next step.

Common air-conditioning problems

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.

What Cornerstone checks

  • Thermostat operation
  • Electrical components
  • Airflow and filter condition
  • Drain line and safety switch
  • Indoor and outdoor coil condition
  • Refrigerant-related indicators
  • Blower and outdoor fan operation

Repair examples

We explain what failed before discussing cost.

Repair cost depends on the failed component, system accessibility, equipment age, and warranty status. Cornerstone provides options before work begins.

No-cool call

A technician verifies power, controls, capacitor condition, compressor response, and airflow.

Frozen coil

Ice is a symptom. Airflow, filters, coils, refrigerant indicators, and run conditions all need review.

Drain concern

Clogged drains and float switches can shut systems down to reduce water damage risk.
