Well, my central AC conked out completely during one of those 97 degree/97% humidity Chicago summer days and I got a new one with matching furnace, automatic humidifier for the winter, whole-house electrostatic air cleaner, and programmable thermostat. Very energy efficient, which may become more important as time goes on.

BTW, Trane has been giving nice rebates on such systems; check with your contractor if you are in the market.

Anyway, I put the whole $9000+ shebang on my Citibank AAdvAAntage MC and was wondering what the most anybody here has ever put on a mileage card?
