Understanding How Air Conditioners Work

Understanding how air conditioners work can help you troubleshoot issues when your AC won’t cool below 75. Air conditioners cool the air by removing heat and humidity from the room. This process involves various components, including the compressor, condenser, and evaporator.

The compressor compresses the refrigerant, which then flows to the condenser to release heat. As the refrigerant cools down, it moves to the evaporator, where it absorbs heat from the room. The cooled air is then circulated back into the space.

The refrigerant plays a crucial role in the cooling process, as it continuously cycles between the evaporator and the condenser. If your AC is not cooling properly, it could be due to a refrigerant leak or a malfunctioning component within the system.

Understanding the basics of how your air conditioner operates can help you identify and potentially resolve the issue.
