Had the AC tech show up this afternoon, and found that a brazed joint in the copper tubing going to the compressor had sprung a sizable leak. Temps were hitting 86 degrees in the house by then, so it was starting to get a bit uncomfortable. But he silver soldered the joint, tested pressure, then evacuated all the air from the system and recharged it with freon. Luckily it was all under that 10 year warranty we got when it was originally installed.
Last night it wasn't too uncomfortable sleeping, but I think tonight might have been a bit worse.
If you ever want to truly appreciate air conditioning, turn it off for a day when it is 96 degrees outside and humidity about the same. Will make you want to look up Willis Carrier's grave site and lay some flowers upon it.
