Before diving into repairs, it’s helpful to understand the fundamental principles behind how a window AC operates. This knowledge will aid in your troubleshooting efforts. 24 Hour Emergency Heating Service Emergency Ac Repair Near Me 24 7 Air Conditioning Service Local Air Conditioning Service
- Refrigerant: The heart of the AC system is the refrigerant, a special fluid that absorbs heat from the indoor air and releases it outside.
- Compressor: This component compresses the refrigerant, increasing its pressure and temperature.
- Condenser: The hot, high-pressure refrigerant passes through the condenser coils, where it releases heat to the outside air.
- Expansion Valve/Capillary Tube: This valve reduces the pressure of the refrigerant, causing it to cool down.
- Evaporator: The cold, low-pressure refrigerant absorbs heat from the indoor air as it passes through the evaporator coils.
- Fan: Two fans are essential: one to circulate air over the evaporator coils (cooling the room) and another to blow hot air over the condenser coils (releasing heat outside).
