Understanding How AC Wall Units Work Emergency Heating Repair Near Me Emergency Ac Repair Near Me 24 7 Ac Service Ac Unit Replacement Near Me

Before diving into repairs, it’s helpful to understand the basic principles of how an AC wall unit functions. These units operate on the principle of refrigeration, using a refrigerant to absorb heat from the indoor air and release it outside. Here’s a simplified overview of the key components and their roles: 24 Hour Emergency Heating Service Emergency Air Conditioner Repair Near Me 24 Hour Hvac Hvac Air Conditioning Service

• Compressor: The heart of the system, the compressor pressurizes the refrigerant, raising its temperature and pressure.
• Condenser Coil: Located outside, the condenser coil releases the heat absorbed by the refrigerant.
• Evaporator Coil: Located inside, the evaporator coil absorbs heat from the indoor air, cooling the room.
• Refrigerant: A special fluid that circulates through the system, absorbing and releasing heat.
• Expansion Valve (or Capillary Tube): This component reduces the pressure of the refrigerant before it enters the evaporator coil.
• Fan Motors: These motors circulate air over the coils, facilitating heat exchange.
• Filters: These trap dust and debris, preventing them from clogging the coils and reducing efficiency.
