I returned home after the plane ride, walked into the house and began sweating.

My assumption was the that the air conditioning was off, but when I looked at the panel, it was running.

After much investigation, I finally found that the entire chiller coil was frozen over with ice. Solid ice. I just spent the last 2 hours trying to defrost it.

The fan needs to run all night and probably all day to get all the ice melted and the water cleared out before I can turn on the AC again.

What a welcome home. Time for bed.
