Improper Thermostat setting
When there is improper thermostat setting then it can cause the air conditioner to blow warm air. In this situation, air conditioner fans run but it does not blow cold air.

Blocked Condenser Coils
In certain cases, a blockage in condenser coils causes an air conditioner to stop producing cold air. The condenser coil produces warm air that gets removed into the environment. However, when the dust accumulates in the condenser coil then it restricts heat from flowing out.
This situation causes difficulty for air conditioners and other components to produce cold air. It is important to look after this concern to have a proper cooling air conditioner. Here are the following ways to get rid of blockage in condenser coils
