- Low refrigerant can cause your AC to blow cool, but not cold air. A refrigerant leak can be the culprit. This issue requires professional attention.
2. Dirty Air Filter:
- A clogged or dirty air filter can restrict airflow, reducing the AC's cooling capacity. Check and clean or replace the air filter regularly.
3. Thermostat Issues:
- Ensure your thermostat is set to a temperature lower than the room's current temperature. Additionally, check if the thermostat is positioned correctly and not near heat sources.
4. Blocked Vents:
- Make sure the vents and registers throughout your home are open and unobstructed, allowing proper airflow.
5. Outdoor Unit Problems:
- Check the outdoor AC unit (condenser). Ensure there's no debris or vegetation blocking it, as it can affect heat transfer.
6. Compressor Problems:
- If the compressor (the heart of the AC system) is malfunctioning, it may not cool efficiently. This typically requires professional diagnostics and repair.
7. Evaporator Coil Issues:
- A dirty evaporator coil can reduce cooling efficiency. The evaporator coil is located in the indoor unit and may require professional cleaning.
