An AC unit operates on a closed-loop system that utilizes a refrigerant to cool the air. The key components include: 24 Hvac Service Near Me Emergency Air Conditioner Repair Near Me 24 7 Air Conditioning Service Air Conditioning Specialist Near Me

• Compressor: The heart of the AC system, the compressor pressurizes the refrigerant, increasing its temperature.
• Condenser: Located outside the home, the condenser releases heat from the refrigerant, transforming it from a high-pressure gas to a high-pressure liquid.
• Evaporator: Located inside the home, the evaporator absorbs heat from the indoor air, cooling it down.
• Refrigerant: A specialized fluid that absorbs and releases heat.
• Expansion Valve (or Metering Device): Regulates the flow of refrigerant into the evaporator.
• Blower Motor: Circulates air over the evaporator coil, distributing cool air throughout the space.
• Ductwork: Carries the cooled air from the AC unit to vents throughout the building.

The cooling process involves the refrigerant absorbing heat from the indoor air, circulating through the system, and releasing heat outside. Understanding this cycle will help you identify where a problem might be occurring. 24 Hour Emergency Air Conditioning Service Near Me Ac Emergency Repair Near Me 24 7 Ac Service Local Air Conditioning Service
