Q: Air conditioning not cooling

asked by on

My air conditioning is not cooling.

A number of different things could be causing this issue. The most common cause is that the system is low on refrigerant. This would have been caused by a leak in the system. The first step would be to turn on the air conditioning and find the A/C compressor. Once the A/C compressor is found make sure the clutch pulley on the front of it is spinning. If not, your compressor is not even running. If this is the case, I would have the air conditioning system inspected by a certified professional. They will likely recycle the refrigerant remaining in the system and refill it to the correct amount to find leaks. Once the leak is found, have it repaired as soon as possible in order to save money on wasted refrigerant and decrease pollution of the ozone layer. Other issues may cause this problem and may be noticed during the inspection. A low amount of refrigerant due to a leak is just the most common cause of poor cooling issues. Do not attempt to add refrigerant yourself as there is no way to measure the actual amount in the system without an A/C evacuation and recharge machine.
