    Coil Keeps Freezing Up, We Don't Know Why

    Previous company she had out gave her the ole gas-n-go. Unit still icing over. I pulled the filter out and it looked new (always a warning sign). I opened up the plenum and found:



    Of course, I couldn't just clean the evap and leave the blower unattended. I pulled the blower and discovered this gem:



    "Oh, we ran it without a filter for a few weeks until we could get a new one."

    Did ya?

    most guys including me, some times just check the filter, but don't open the blower door,this is a good reason to always be a little more inqusitive. nice photo!

    Picture looks like the blower wheel has been cleaned without the motor being cleaned.

    the new filter is usually a warning.
    I got scolded by a customer once for pointing out that the old filter, that looked like a piece of cardboard, in the trash can was the issue.
    trash can few feet from cond, it was sticking out so I had to look.
    unit checked out fine and no call back.

    Had a no cool call.

    The customer was a filter company.

    The unit a residential split, the space it served was their filter making area.

    The air handler didn't have a filter in it and the evaporator was plugged with scrap filter material.



    You would think they would know better.
    Waddya mean don't thaw out the frig with a knive?

    Found one today where the evap was on the return side of the furnace and the filter was between the evap and furnace. I guess the coil is supposed to act like a prefilter.

    Few weeks?....how bout a year or two.

    You will probably be going back soon to change that blower motor out.
