What happends when your Home Cental Air unit freezes?

[trularin]

Undy has a nice list.

What is NOT happening is the freon is being "changed".

If it freezes up, IE ice forms on the compressor parts, that means there is not enough conversion taking place. Does the fan blow in the furnace/air unit?

In a recent set of events for our family, the blower motor was drawing too much current causing the system to shut down the motor. No air across the coils makes the system ice at the compressor because there was not enough conversion taking place.

Insufficient freon should be low on the list of problems...unless something happened to cause the loss.
Electrical - like a motor being shut down - is probably higher in the list.

I do not know how technically inclined you are, but some of these guys can get big money to do a small thing.

I hope this helps!

...and frequently do! Heck it pays for the Cobra, the Z06 and last but not least, the girlfriend



On an older residential system refrigerant loss is by for the most common culprit when coil/line freeze-up is the symptom.. With Freon 22 having gone the same route as the dinosaur and Freon 12 it's sometimes the best thing to bite the bullet and recapitalize. It can nickel, dime and dollar you to death ... and ... you still end up replacing it. I could write a book on the subject.

The new systems take R-410A and the major components in most cases aren't interchangeable with R-22 components.
