a/c freeze up

I finally got my ac/heater up and running with all of your electrical help. Thanks again.

But now something else happened 2 days ago.

It's been terribly hot (Texas) and the a/c unit had been working fine. I woke up one night because it was getting hot in the house. I went outside and found ice on the pipes outside. I turned the a/c off for a day, and it seems to be running fine now. What caused the icing up?

Thank You

Hot in Texas...

Check the air filter. If it is dirty when the unit was running and froze up, installing a new, clean filter of the proper size should take care of the problem.

The filter must completely fill the filter rack so that dirty air will not bypass the filter.

The indoor coil could be dirty. It is a pain to get to and even worse to clean. Most contractors avoid this job as much as possible.
The blower wheel could be dirty as well.

The system may also be short of refrigerant.
Finally, the problem may be all of the above.
