I'm planning on getting a Trane XL15i Heat Pump (Model 4TWX5048). For $200 more (after rebate), I can get the XL16i Heat Pump (Model 4TWX6048). Worth it?
I also noticed that some model numbers have a letter at the end. The quote from my installer doesn't. Should I have him be more specific? (I've seen threads saying that a "C" version is better than the "B" version, etc.)
Lastly, the thermostat is listed as Trane TCONT802AS32DA? Any problems with that one? Should I ask for a different (better) one?
I live in SEattle and will have a furnace (95% / variable speed) backup. My propane is getting expensive but electricity is dirt cheap.
Thanks for the time.
