Oh boy... I have a two-part AC unit for my house. Outside, I have a Carrier WeatherMaker compessor. Inside, I have a Unico air handling system. There's one Carrier/Unico for the upstairs, and one Carrier/Unico for the downstairs.
Well, my upstairs Unico seems to have frozen. Dunno how that happened, but the line got plugged or the filter got blocked or something. And the line has frozen all the way down to the Carrier outside.
They can't be here until Tuesday. And this weekend will have the hottest days of the year...
