1. Check the thermostat. Make sure the thermostat is set to the "cool" setting and the temperature is set below the current room temperature.
2. Check the air filter. If the air filter is clogged, it can restrict air flow and prevent the air conditioner from cooling the room.
3. Check the condenser coils. The condenser coils are located on the outside of the air conditioner. They can become clogged with dirt, leaves, and other debris. If the condenser coils are clogged, it can prevent the air conditioner from cooling the air properly.
4. Check the refrigerant level. If the refrigerant level is low, it can prevent the air conditioner from cooling the air properly.
5. Check the compressor. The compressor is the heart of the air conditioner. If the compressor is not working properly, it can prevent the air conditioner from cooling the air.
If you are unable to find and fix the problem, you may need to call a professional HVAC technician for help.
