• Compressor: The heart of the AC system, the compressor pumps refrigerant, the cooling agent, through the system.
• Condenser Coils: These coils release heat from the refrigerant to the outside environment. They are typically located on the outside of the unit.
• Evaporator Coils: These coils absorb heat from the air inside the room, cooling it. They are located inside the unit, often behind a filter.
• Refrigerant: A chemical compound that absorbs and releases heat, allowing the AC to cool the air.
• Fan Motors: These motors power the fans that circulate air over the condenser and evaporator coils.
• Filters: These filters trap dust and debris, preventing them from entering the coils and reducing the unit’s efficiency.
• Control Panel: This panel houses the controls for setting the temperature, fan speed, and other settings.
• Thermostat: This component monitors the room temperature and regulates the compressor and fan operation to maintain the desired temperature.

  • Inspect the Power Cord: Look for any damage to the power cord. If the cord is frayed or damaged, replace it immediately.
  • Check the Internal Fuse: Some units have an internal fuse. Consult your owner’s manual to locate and check the fuse. If the fuse is blown, replace it with a fuse of the same rating.
