Dirty air filter, Low refrigerant levels
Dirty air filters restrict airflow, leading to reduced cooling efficiency. Low refrigerant levels can also cause the air conditioner to not cool properly.
Steps to Troubleshoot
1. Check and clean the air filters to ensure proper airflow.
2. Inspect for any visible leaks in the refrigerant lines.
3. If refrigerant levels are low, contact a professional for recharging.
4. Verify that the thermostat is set to the correct temperature.
5. Ensure that the condenser unit outside is clear of any debris.
6. Check for any obstructions blocking the airflow around the condenser unit.
7. If issues persist, consider contacting an HVAC technician for further diagnosis.
