You can also clean your air conditioner condenser yourself. But keep in mind that you should not break any part of the Unit.
6) Refrigerant leakage – Air Conditioner Not Blowing Cold Air
Refrigerant cycles run inside the air conditioner. if our Air conditioner not blowing cold air but running, the main reason in the refrigerant is leaked from the unit. Even if the air conditioner is operational, the cold air is not blowing. And you checked the filters, blowers, and condensers. You must hire air conditioner technology immediately.

7) Air Conditioner Is Under Capacity
Before installing the air conditioner in your home, we have to see what is the size of our room. We can put 1 tonne of the air conditioner inside the space of 10/10 feet (100sqft). If The Room Size is Large, Your AC will not capable to cool your room. you will feel Uncomfortable.
Air Conditioner Not Blowing cold Air but Running.
8) Leakage in the Room and Ducting
When we start the air conditioner, it is important to keep in mind that all windows and doors in our room should be closed. If there is a leakage in our room, then cooling will not be possible. Similarly, if your ducting is leaked from anywhere, you will not get air flow.

By which the refrigerant’s circulation will be stopped. At this situation, you can say that our air conditioner not blowing cold air.
We use the capacitors to run the air conditioner’s compressor. After a few years, the capacitor becomes weak. it is cannot bear the compressor’s load. Because of this, our AC does not do the cooling.
If our AC’s PCB coil stops working, the indoor unit will not be supplying the energy to the outdoor unit. Because of this, our AC will not blow cold air.
Often our compressor gets grounded or dead. Or it becomes less Pumping. Even then our AC cold air will not blow.
Outdoor motor not working
If our outdoor unit’s motor has jammed. So our AC condenser’s heat will not be able to retire. This will harm our compressor. the compressor will heat over. In such a condition the compressor will Trip every minute, which will not become cool your room.
