After a terrible night, I'm happy to say that our a/c seems to be fixed. The guy that came out said that the compressor overheated and quit working. It's still not very cool in the house, but he said it will take a few hours to cool things back down again and to not turn the temperature down too low all at once--to try to drop the temp in the house a couple of degrees at a time so as not to overwhelm the works. Whatever, I'm just grateful cool air is coming out of the vents again. And we didn't have to pay anything even though the last time the a/c broke it was for a different issue.
Last night at about 1:30 in the morning we discovered that the portable a/c unit was leaking all over the rug in our den. We had to scramble to move furniture, get the rug up, mop up the water, etc. We ended up dragging an old plastic kiddie pool from the garage to put the unit inside of to protect the floors from leaking water. It must have been after 2am before we were finally able to (try to) sleep, and Gregg had to get up early for work. The house is in disarray still, but I'm exhausted from 2 nights of hardly getting any sleep. I'll have to deal with all that after a good nap.
