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.
