I am replacing my existing 2 ton HP and inside air handler. I've decided to install a Trane unit. However, at this point, I am confused as to what to install. I have gotten quotes from 3 local Trane installers and don't know if they are suitable, designed properly, or keep looking. I'm looking for a good system that will work properly and everyone (installer and me) is happy with the job/price.
Here is the info.
I plan to go with 410A instead of R22
all dealers will replace gas and liquid lines
Trane XR14 T4TWR4024A1000A
Air Handler T4EE3F31B1000!
controller - not specified
10 kw electric heat
one year warranty on parts and labor then Trane parts warranty
Trane XR13 T4TWR3024A1000
Air Handler T4TEC3F24B1000A
10 kw backup heat
5 years parts and labor warranty through dealer
Trane XL15i 4TWX5024
Air Handler 4TEC3F24A1000A
10 kw electric backup
one year parts and labor warranty then Trane parts warranty
Dealer 1 cost is $500 less than dealers 2 and 3 which are just about the same.
1. Which system should I go with, or keep looking?
2. Any problems with the combination of HP and air handler. Reading the posts, do I need a variable speed air handler, 4TEE model or the 4TEC with the XL15I HP. Does it make a difference?
3. Should I get an extended warranty directly from Trane? Anyone know how much it would cost? Is it worth the money?
4. Anything else you might suggest?
Thanks for everyone's help.
