Considering an upgrade to the XV90 from the XR90 and my dealer/builder
indicated the Trane would run me about $650 - $150 rebate in WI for net
upgrade of $500. What I am trying to determine is if the upcharge
worth it and at what point would I break even for the $500 based on
savings from motor running constantly vs single stage and what is the
savings in my LP consumption from the gas heated with lower stage
flame. I am total rookie here on furnance but given the mild to harsh
WI winters I want to make a wise decision. I am also getting a 13 SEER
Trane AC unit. Dealer indicated the upgrade in the furnance and combo
with the AC would give me the ability to remove 20% more humidity from
home because of furnace and also said something to that effect in their
marketing brochures. Please help as I need to make a final decision in
next 2 weeks and let the contractor know my decision.
