    You should check blower motor amps with panel on to achieve true reading, otherwise amp draw will be higher than normal with panel off.

    when you wash the condensing coils, i think you should wash up and down motion, otherwise yo could flatten the fins.

  • DrZarkloff:

    The cost of a contactor should be considered in the budget.

  • Suiscycho:

    Checking the current draw on all loads is a very good point. Should you really replace contactors? What about when you work at apartment communities where there are tons of them to be replaced? That can be quite costly.

    Thanks for the offer. I always have to be sure the filter techs refastened the screws on the panel doors. They seem to have a problem with that.
