An AC that runs but isn’t blowing cold air usually indicates lost cooling capacity from low airflow, thermostat/control issues, or a refrigerant problem. The most common real‑world trigger is reduced airflow or a small refrigerant leak that allows the indoor coil to ice, so the system moves air but can’t remove heat. A spinning fan or humming outdoor unit doesn’t confirm cooling; only a measured temperature drop across the coil does. We handle these no‑cool‑but‑running calls across West Orlando with methodical diagnostics and clear repair‑or‑replace options. Emergency AC services are available after the core evaluation.
Try these simple checks before service:
- Set the thermostat to Cool and Auto, then lower 3–5 degrees.
- Replace a dirty air filter.
- Clear leaves from the outdoor condenser and keep about 18 inches of open space.
- If you see ice on the lines or air handler, shut the system off to thaw.
If warm air continues after these steps, schedule a professional diagnostic to check controls and refrigerant leaks.
