Most ACs that run but don’t cool have airflow or refrigerant issues. Start with these checks, then schedule service if cooling doesn’t return.
- Set thermostat to COOL and 3–5°F below room temp.
- Replace a dirty filter (every 1–3 months).
- Clear debris around the outdoor unit; rinse coils.
- Make sure all supply/return vents are open.
If you see ice or still get warm air, turn the system off and book a diagnostic. A technician can check refrigerant levels, clean coils, and inspect electrical connections. Free repair-or-replace consultation available in Marion, IN.
