• Refrigerant: The lifeblood of your AC system, refrigerant is a special fluid that absorbs and releases heat. It cycles through the system, changing between liquid and gas states.
• Compressor: The heart of the AC system, the compressor pressurizes the refrigerant, increasing its temperature.
• Condenser Coil: Located outside, the condenser coil releases heat from the refrigerant, turning it from a hot gas into a liquid.
• Evaporator Coil: Located inside, the evaporator coil absorbs heat from the air inside your home, cooling it down. This is where the freezing typically occurs.
• Expansion Valve/Metering Device: This component regulates the flow of refrigerant into the evaporator coil.
• Blower Motor: This motor circulates air across the evaporator coil, distributing cool air throughout your home.
• Air Filters: These filters trap dust, dirt, and other particles, preventing them from clogging the system.

   • Blower Motor Problems: A malfunctioning blower motor may not circulate air properly.

2. Low Refrigerant Levels: Refrigerant absorbs heat from the air inside your home and releases it to the outside. Low refrigerant levels can cause the evaporator coil to freeze because there isn’t enough refrigerant to absorb the heat effectively.
