A/C operational check

When we arrive at the home we first talk to the customers and listen to any concerns that they have about the equipment to give us a good idea of how the unit has been working recently.  After that we go through an operational check list:

  • We check what type of refrigerant is in the system
  • We check the indoor blower and its bearings
  • We check the filtration system
  • We check the condenser fan, its bearings and blades
  • We check the condenser coil to see if it’s damaged or plugged with dirt
  • We check the evaporator coil to see if it is plugged with dirt
  • We check the condensate line to be sure it is draining properly
  • We check the contacts on the contactor
  • We check the dual run capacitor to see if it is within its proper operating range
  • We check the compressor for any shorts
  • We check the high and low refrigerant pressures
  • We check the Super heat and the Sub cooling to be sure we have the proper refrigerant levels
  • We check the TXV or orifice
  • We check the indoor temperature verses the outdoor temperature
  • We check the temperature difference between the return air and the supply air
