Understanding the Basics of AC Operation 24 Hour Emergency Heating Service Near Ac Service Ac Hvac Repair Near Me
Before we dive into troubleshooting, it’s helpful to understand how your air conditioner works. The basic principle is quite simple: Phoenix Air Conditioning Repair Hvac Service Companies Near Me Ac Guys Near Me
- Refrigerant: Your AC uses a special chemical called refrigerant to absorb heat from inside your home and release it outside.
- Compressor: The compressor is the heart of the AC system. It pressurizes the refrigerant, which increases its temperature.
- Condenser: The hot, high-pressure refrigerant flows to the condenser, located outside your home. Here, the refrigerant releases its heat to the outside air, turning it into a high-pressure liquid.
- Expansion Valve/Metering Device: This component reduces the pressure of the liquid refrigerant before it enters the evaporator coil.
- Evaporator Coil: The low-pressure, cold refrigerant enters the evaporator coil, located inside your air handler. As warm air from your home blows across the coil, the refrigerant absorbs the heat, cooling the air.
- Fan: A fan blows the cooled air back into your home through the vents.
- Cycle: The refrigerant then returns to the compressor, and the cycle repeats.
