    Maintenance.

    Amp Draws on a Monthly Service ,,, what's your thoughts.

    AHU for a Market & Exhausts.
    The primary function of the design engineer is to make things difficult for the fabricator and impossible for the serviceman.

    Why? Is there a history of motors having a bad day over there?

    Monthly might be a bit excessive. But it can't hurt especially if they are paying. If I'm going balls to the wall on a maintenance im checking everything. Wiring connections, switches, amperage, as well as the normal filters and pressures and all that jazz

    Checking the amp draw is a good tool IF the old readings are available to compare #'s. Just like meging larger motors.

    Also, amp draw measurements are relatively meaningless if not accompanied by suction and discharge pressures as well as supply voltage. It's like recording receiver levels, which don't mean much unless you have additional info.

    If there extra time leftover I might but for a market time is better spent leak checking, airflow, drains, oil level &pressure etc as icemeister stated not a lot can be gained by amp draw alone. I think amp draws on heaters would be more valuable.
    Honeywell you can buy better but you cant pay more

    I told my wife when i die to sell my fishing stuff for what its worth not what i told her i paid for it

    Pressures & Supply Voltage are Recorded also.
