Coil Keeps Freezing Up, We Don't Know Why

[dougfamous]

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.

You've heard of one of those hog hair filters? That is the new cat hair filter. Lets nothing through, not even air! Only 19.95, and now for a special time, 2 for the price of one. Call now.

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.
