Understanding How Air Conditioning Works 24 Hour Ac Company Residential Air Conditioning Repair Emergency Hvac Service Ac Guys Near Me

Before we dive into the problems, let’s quickly recap how an air conditioning system works. AC units use a refrigerant to absorb heat from the inside air and release it to the outside. The main components involved in this process include: Emergency Heating Repair Near Me Ac Service Near Ac Repair Around Me 24 7 Ac Repair

• Compressor: The heart of the AC system, the compressor compresses the refrigerant, raising its temperature and pressure.
• Condenser: Located outside, the condenser releases the heat absorbed by the refrigerant, turning it from a gas to a liquid.
• Evaporator: Located inside, the evaporator absorbs heat from the air inside your home, cooling it down.
• Refrigerant: A special fluid that cycles through the system, absorbing and releasing heat.
• Expansion Valve: This valve regulates the flow of refrigerant into the evaporator.
• Blower Motor: This motor circulates air over the evaporator coil, distributing the cooled air throughout your home.
