Althoff Industries Furnace Tune-Up Guide

  • Verify accuracy and proper operation of the thermostat
  • General observation of all venting and ductwork
  • Measure ductwork system static pressures and evaluate them against benchmark levels
  • Perform combustion analysis on the furnace to ensure safe and proper combustion
  • Measure and verify proper temperature change at the system
  • Take amp draws of the blower motor
  • Take amp draws of the inducer motor
  • Check blower motor capacitor for proper microfarad level
  • Observe condition and balance of the blower motor wheel
  • Clear condensate drain and ensure proper operation
  • Remove and clean the flame sensor
  • Perform a visual inspection of the burners. If the carbon monoxide levels dictate, pull and clean them also
  • Perform a visual inspection on the heat exchanger
  • Take an ohm reading on the hot surface ignitor
  • Remove and clean the pilot assembly
  • If applicable, replace the thermocouple
  • Clean condensate trap for high efficiency furnaces
