difference betwee trane 4ttx6036 and 4ttz0036
We are getting estimates on the Trane XL20i and two contractors have given us bids on two different outdoor units: Trane 4TTX6036 AND 4TTZ0036(airhandlers are the same: (4TEE3CO4). The difference in price is about $600.
It is difficult to compare when the quotes are on different models. We live in South Florida and are aware of the FPL rebate and government tax credit. We have a White-Rodgers digital thermostat now.. do we need a different type with the new system?
We'd appreciate your advise. Thanks!
