  • Determine that proper voltage is being supplied to the unit by providing Rated and Actual Volt Readings.
  • Provide an Ambient Temperature reading for comparison to proper system pressures.
  • Perform and document Suction and Discharge Pressure readings to determine proper refrigeration charge and system operation (Cooling Inspection).
  • Provide an incoming (natural) Gas Pressure reading to verify sufficient supply for proper heating operation (Heating Inspection).
  • Provide dry-bulb Discharge and Return Air Temperature readings used to indicate proper compressor operation and unit temperature rise readings.
