• Compressor: The heart of the AC system, the compressor pressurizes the refrigerant, which is the working fluid that absorbs and releases heat.
• Condenser Coil: This coil, typically made of copper or aluminum, dissipates the heat absorbed by the refrigerant, releasing it into the outside air.
• Fan Motor: The fan motor drives the fan blades, which pull air across the condenser coil to facilitate heat dissipation.
• Fan Blades: These blades are responsible for circulating air over the condenser coil.
• Electrical Components: These include the capacitor, contactor, and wiring, which provide power and control the operation of the compressor and fan motor.
• Refrigerant Lines: These lines carry the refrigerant between the outdoor and indoor units.
• Control Board: This board manages the overall operation of the outdoor unit, including the compressor, fan motor, and other components.
• Housing: The protective enclosure that houses all the components.

2. Visual Inspection:
   • Check for Obvious Issues: Look for loose wires, damaged components, or signs of leaks.
   • Inspect the Condenser Coil: Check for dirt, debris, and obstructions that may restrict airflow.
   • Examine Fan Blades: Ensure the fan blades are intact and free of obstructions.
3. Clean the Condenser Coil:
   • Turn Off Power: Again, disconnect the power to the unit.
   • Use a Fin Comb: Use a fin comb to straighten any bent fins on the condenser coil.
   • Rinse with Water: Use a garden hose with a gentle spray nozzle to rinse the coil from the inside out. Avoid using high-pressure washers, which can damage the fins.
   • Allow to Dry: Let the coil dry completely before restoring power.
