Question on HVAC Abbreviations TLC & PTU

    Could someone give me the HVAC definitions for 'TLC and PTU' when used
    for a gas mid-efficient furnace?

    The reason I ask is my daughter's 1993 Lennox G24M2-75A-2
    mid-efficient hot surface ignitor furnace has been (IMHO) rapidly
    cycling lately.

    I came across a service bill at her home from many years ago (before
    they bought the home) and it had the notation 'Recommend TLC or PTU'.

    So I was thinking - maybe TLC means: Temperature Limit Control? But
    PTU?
    ..
    ..
    ..
    They had their ducts cleaned in the summer - but the furnace was not
    cleaned at that time. I'm going to recommend that they have the
    furnace cleaned but was wondering if the TLC or PTU might also require
    attention (provided I can figure out what they are).

    The furnace has the normal pre-ignition exhaust fan run for 1 minute
    then
    normal ignition but the gas runs for only for 4 minutes (which seems a
    short period of time to me at least compared to my furnace)
    The blower fan starts normally after the 1 minute heat exchanger warm
    up period,
    After the gas shuts off, the blower runs for the cool down period for
    3 minutes to fan off
    There is a 2 minute delay - which seems abnormally short - then the
    ignition sequence restarts.

    Total cycle time 10 minutes.

    They have been doing lots of renovations - some involving work around
    the ducts & I suspect they may have kicked up a lot of dust onto the
    heat exchanger.

    We replaced the blower compartment filter. The problem persists.

    Thanks, Cindy

    I tend to think it means: Recommend Tender Loving Care or Pitch The Unit.

    PTU means Precision Tune Up. TLC means Tender Loving Care.
