Condenser Unit is Blocked If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser coil. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your home.
Why is my AC working upstairs but not downstairs?
Why Is My Air Conditioning Working Upstairs, But Not Downstairs: The Short Answer. If you’ve been having problems sleeping during the summer because it’s too hot upstairs, you’re not alone.

Air leaks and poor insulation are a common cause for making your house feel hot, even when the AC is working, as they can allow the air your air conditioner has worked so hard to cool to escape, leaving your house hot.

Why is my central AC not blowing cold air?
Air Conditioner Not Is Blowing Cold Air Because of the Refrigerant Pressure. Evaporator coils and refrigerant issues also result in problematic air conditioning. Refrigerant plays a key role in air conditioning. During the cooling process, refrigerant is compressed, dropping it to a very low temperature.
What to do if your AC is not blowing cold air?
Try cleaning your air conditioner’s filter and the coils to see if improving the airflow fixes the problem. If there is ice buildup, you’ll need to run the unit with just the fan in order to melt it off.
