Understanding the AC System: A Brief Overview 24 Hour Ac Company Near Ac Service 24 7 Ac Repair

Before we dive into the problems, it’s helpful to have a basic understanding of how an AC system works. The core components of an AC system include: Emergency Heating Repair Near Me Hvac Service Companies Near Me 24 7 Air Conditioning Repair

• Compressor: The heart of the system, the compressor pressurizes the refrigerant, increasing its temperature.
• Condenser: Located outside, the condenser releases heat from the refrigerant, turning it into a high-pressure liquid.
• Expansion Valve/Orifice Tube: This component reduces the pressure of the refrigerant, causing it to cool down.
• Evaporator: Located inside, the evaporator absorbs heat from the air, cooling it.
• Blower Motor: This motor drives the fan that circulates air over the evaporator coils, distributing cool air into the space.
• Refrigerant: A special fluid that absorbs and releases heat, circulating through the system.
• Ductwork: The network of ducts that carries the cooled air throughout the building.
• Thermostat: The control center that regulates the temperature and controls the operation of the AC system.
