My AC is not cooling in Houston. What should I do first?

Start with thermostat settings, air filter condition, and breaker checks. If cooling still fails, contact a licensed Houston HVAC contractor for refrigerant, coil, or compressor diagnostics before heat stress worsens.

  • Set thermostat to cool and lower target temp
  • Replace clogged filter
  • Check indoor/outdoor unit power
  • Schedule same-day HVAC service
