Main Causes of AC Not Cooling
Potential Issues with the Airflow
-
Blocked or dirty air filters: A primary reason for ac not blowing cold air is a clogged filter.
-
Ductwork issues: Leaks or obstructions in the ducts can hinder airflow, affecting cooling.
Maintenance Tips
Regularly replacing or cleaning air filters every 1-3 months can drastically improve your AC’s performance.
Refrigerant Problems
- Low refrigerant levels: Inadequate refrigerant can cause the air conditioner not blowing cold air but running.
- Signs of refrigerant leaks: Hissing noises, ice on compressor, and high energy bills.
Expert Advice
Contact a certified technician if you suspect a refrigerant leak. DIY refills can be hazardous and might not solve underlying issues.
Troubleshooting Steps for AC Not Blowing Cold Air
- Check thermostat settings: Ensure it’s set to cool mode and the temperature is lower than the room’s current temperature.
- Clean or replace air filters: This can often resolve airflow issues making the ac not cooling efficiently.
- Inspect outdoor unit: Remove any debris obstructing the condenser coils. Poor external airflow can impact the whole system’s effectiveness.
