The key components include: Emergency Heating Repair Near Me Ac Service Near Ac Repair Around Me 24 7 Ac Repair

• Compressor: This is the heart of the AC system, compressing the refrigerant and circulating it throughout the system.
• Condenser: Located outside, the condenser releases the heat absorbed by the refrigerant.
• Evaporator: Located inside, the evaporator absorbs heat from the indoor air, cooling it.
• Refrigerant: A special fluid that absorbs and releases heat, circulating through the system.
• Expansion Valve (or Orifice Tube): Controls the flow of refrigerant into the evaporator.
• Blower Motor: Circulates air over the evaporator coils to cool the air and distribute it throughout the space.
• Ductwork: The network of pipes and vents that distribute the cooled air.
