OK I'm posting here too in addition to alt.hvac. I'm trying to decide
between 2 Carrier Puron units - a 14 SEER YX with variable speed
handler and Thermidistat vs a 13 SEER (don't have model - I think YZ)
with fixed speed. The price difference after rebates is within $300 so
I'm thinking of the 14 Seer. I'm wondering if the VS handler is
reliable ? How about the Thermidistat, what does it do over and above a
standard programmable? Any opinions? Thanks.
