Understanding the Basics: How Your AC Works Emergency Heating Repair Near Me Ac Repair Company Near Me Air Conditioning And Heating Services Near Me

Before we dive into troubleshooting, it’s helpful to understand the fundamental principles of how an AC unit functions. An AC unit works by removing heat and humidity from the air inside your home and transferring it outside. This process involves several key components: 24 Hour Emergency Heating Service Air Conditioning Repair Companies Near Me Heating Ac Service Near Me

• Refrigerant: A special fluid that absorbs heat from the indoor air and releases it outside.
• Compressor: The heart of the AC system, the compressor pumps the refrigerant through the system, increasing its pressure and temperature.
• 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 it down.
• Expansion Valve: Controls the flow of refrigerant into the evaporator coil.
• Blower Motor: Circulates air over the evaporator coil to cool the air and then distributes the cooled air throughout your home.
• Ductwork: The network of pipes that carries the cooled air from the indoor unit to the vents in your rooms.

When the AC unit is running, the refrigerant absorbs heat from the indoor air as it passes through the evaporator coil. The refrigerant then travels to the compressor, where it is compressed, increasing its temperature and pressure. The hot refrigerant then flows to the condenser coil outside, where it releases its heat. After releasing the heat, the refrigerant returns to the evaporator coil to repeat the cycle.
