(AHU) Air Handler Unit typically includes the following:

     – Condensate system: water, or condensate is produced when we cool warm moist air by blowing it over the evaporator coil. The condensate runs down the coil to a collecting pan which drains to piping used to route condensate to an approved drain for disposal

     – Condensate overflow pan or tray is a container placed below the air handler designed to be a safety device intended to prevent unwanted spillage.

     – Blower fan (evaporator fan) in a blower compartment circulates building air into itself from the return ducts and return plenum, and moves that air across the evaporator coil and onwards to the supply plenum and supply ducts in the building.

     – Electrical controls for an air conditioning system include shut-off switch(es) for service at the unit and fuses or circuit breaker(s) at the electrical panel.

     – Evaporator Coil (also called the "cooling coil" is connected to high pressure and low pressure (suction) refrigerant lines.

     -  Return Plenum, connected to return duct system and Supply plenum connected to supply duct system.

     – Thermal expansion valve:  a device located at the cooling coil that regulates the flow of refrigerant rom the compressor/condenser into the cooling coil.
