first cooling check

But it wasn't a check-up.

It was 55° out when they called and they had been running the AC, probably from yesterday and it was nearly 80°. Their AC wasn't working, probably frozen up.

Personally, I like the outside air to be at least 75° with a decent inside load. I have been know to turn on the gas heat for 15-20 minutes or more.

Depending of the age/SEER of the unit, I do it by superheat/subcool. I record the numbers in my files for future reference.

    My oh my....

    It's warming up finally down here. I usually sent out reminder flyers to my regular customers, but Amy beat me to it.

    We set it up for an afternoon, hopefully it'll be warm enough for a good refrigerant system check.

    I love this industry...

    My hats off

    My hats off to is key in any business.
    I for one always assume being a good tech was enough..not so.

    So at what temps is the proper temp to do a good check?

    I was always taught that the evaporator was the boss.So I
    would assume that if you had enough indoor load then one should be able to dail it in.

    I would think if the load on the evaporator was high that it would keep our saturation temp and superheat high and the
    vapor very dense to give good readings.

    Your thoughts?
