The house has been slowly getting uncomfortable all day, at least part of it has. I discovered late this afternoon that the air conditioning unit on the South side of the house — thankfully there is another one on the North end — had stopped working, although the blower continued to cycle the air. We’re still within our warranty period so I called and builder and (naturally) left a message. I doubt he’ll even hear it until Monday morning. In the meantime, I’ve nudged the other AC thermostat down several degrees and set both air-handlers to continuously cycle the air. Hopefully this will slowly transfer some of the cooler air from the North end of the house to the South end.
