Need to replace a 21 yr old Trane 3-Ton heat pump & have no knowledge on heat pump sytems. I have several quotes, however am receiving conflicting info regarding the compatability of the new unit with our exitsing furnace(also 21 yr old Trane). I need enough info to determine if what I’m being told is legitimate advise or a sales ploy.
The quotes are based on a Trane XB13 & XR14; Lennox XP13A-36, and a low-end/construction grade Rheem13. Other than replacing the inside coils to be compatabile with the new unit, any other reasons why the existing furnace would not work with the new unit? I have been told the new unit will not be as efficient with the old furnace. Am willing to deal with that provided, it will heat/cool/dehumidify the house as well as the old unit. Besides, I feel any of the new units will be more efficient than the one being replaced.
Of couse, this was not budgeted. Quotes range from $3500 for Rheem/Lennox (5yr compressor warranty) to $4200 for Trane XR14 (10yr) or $1900 repair job for new compressor & coils (1yr). Any info to help me not waste money would be greatly appreciated.
