Thanks - prices are pretty fixed. One other thing - I'm -pretty- sure (will double check) that the P/L warranty ties me to a certain dealer, who might not be my choice 6 years from now.
Guys - you all -do- make sense, but having 2 systems doubles all the numbers (as I'm not going to 'bet' on which is more likely to fail), and i think you can see that it's hard to ante up close to a couple of K.
good thoughts, though, I appreciate it.
[i wonder, if a well-maintained compressor dies after like, 3-4 years, isn't it possible that with some begging you could get the -manufacturer- to chip in for the labor?]
