Just to update on the air conditioner situation, since I believe we are safely out of the woods. The dude came out this past Monday and made sure the system was all clean, and determined that the air conditioner was freezing up because it was a bit low on Freon. No other maintenance was necessary.
It’s been a few days and our home has stayed wonderfully cool. Hopefully this was a just a routine maintenance need, and we’ll be fine through the summer. I didn’t want to say anything right away, because that’s just asking for Murphy to start F’ing things up, but I think it’s safe to sound the all clear at this point. No one needs to be afraid of coming to my house and suffering from heat stroke.
