Why Is My AC Blowing Warm Air?

Your AC blowing warm air in Greenbrier is usually airflow, thermostat, refrigerant, or electrical trouble. Check the filter and setting first, then call before a small fault becomes a breakdown.
Short answer: Check the filter, check that the thermostat is set to cool and auto, and check the outdoor unit is running. If those are right and the air is still warm, it is usually a refrigerant, airflow, or electrical fault that needs a diagnosis.
Simple checks first
- Filter clean and correctly fitted
- Thermostat on cool, fan on auto, setpoint below room temperature
- Outdoor unit running, not blocked by plants or debris
- Breaker not tripped
When to call
Warm air plus ice on the lines, water around the indoor unit, or a unit that runs nonstop and never cools the house all point to a fault worth diagnosing the same day in summer. See AC repair and common HVAC problems.
