How Your HVAC System Works

Your HVAC system consists of several components that work together to cool and circulate air throughout your home. Here’s a simplified overview of how your air conditioning system works:

  1. Thermostat: The thermostat serves as the control center for your HVAC system. It allows you to set and adjust the desired temperature in your home.
  2. Air Handler: The air handler is responsible for circulating conditioned air throughout your home. It houses the blower fan and the evaporator coil.
  3. Evaporator Coil: The evaporator coil is located in the indoor unit of your HVAC system. It cools and dehumidifies the air as it passes over the cold coils.
  4. Condensing Unit: The condensing unit is located outside your home and contains the compressor, condenser coil, and a fan. It is responsible for releasing heat from the refrigerant and converting it back into a liquid state.
  5. Refrigerant: Refrigerant is a chemical that absorbs and releases heat to cool and dehumidify the air. It circulates between the evaporator coil and the condensing unit, undergoing phase changes to remove heat from the indoor air.
