    AC start-up checklist

    Do you have a service tech check-list for starting up AC systems for the season? I've asked a couple equipment distributors and they don't--but think it's a good idea. Thought you might.

    Check indoor and outdoor coils and clean if necessary.
    Clean and check condensate pan lines and/or pump Incl. check valve.
    Add mildewcide if needed.
    Check condensate pump and/or pan secondary safety switches.
    Replace belt if applicable.
    Clean blower wheel if necessary.
    Lubricate motors if applicable.
    Amp out motors and compresssor.
    Check motor and blower bearings.
    Check integrity of cabinets and ductwork.
    Paint accumulator and rusted parts.
    Be sure all dampers, registers and returns are open.
    Check relays and contactors.
    Check electric supply and draw.

    Check elec. connections for tightness.
    Check pressure switches.

    older a/c system

    I was asked to install two outdoor units to an old a/c install. air handelers were installed 15 years ago with A coil in duct work never used. Line sets, t-stat wire, and line voltage wires ran to the outside of building 15 years ago and never hooked up. the ends of line sets are not taped and exposed to elements. original filters still in unit. would you think line sets and A coil that has never seen a filter still usable.

    A/C Start Up - C&C

    When you take the time to do the job right including
    necessary cleaning, how do you market your sevices?
    The $XX.00, or whatever the going advertised rate in
    your area is, does not make it. We are advertising C&C's
    Starting at $XX to leave the door open for additional
    charges. Sorry,That's not a tech issue.

    Check list

    This is what I put together, I have an updated PDF file that follows the check sheet exactly as I have made it. I will up load it in the next few days. The checksheet I attached can be edited if desired, it is a word file.
