As I was doing my two-mile walk this morning, I thought popped into my head: I'd reset the 440V breakers at the HVAC unit, but not the 220V breakers at the panel. When I got home, I turned the thermostat off; went out and killed the HVAC breakers, then to the garage and killed those breakers. Waited a minute and turned things on in reverse order. HUZZAH! I put the instant-read thermometer down to the AC register vent and... 71 degrees! I immediately closed the windows (which had been opened since I woke up to help get some cooler air in); closed all the blinds to keep sunlight out; and the temperature has SLOWLY been coming down. It's now 4 PM and the house is down to 74 degrees... which tells me that while it's working marginally, it's not working optimally. After a weekend of involuntary sauna therapy, I'll take every drop in temperature we can get, though: especially since the Darling Bride hasn't slept all weekend and is going out of state in the morning for several days. She, more than, I, needs the sleep.
