I recently had a Trane HVAC system installed in my home. The incorrect furnace was installed (supplier and dealer share blame) and since the dealer has to remove and replace the single stage/speed 95% furnace they have offered to upgrade me to a 3-stage 100k max BTU XV95 (I only see 2-stage on the Trane website) for an additional, not insignificant, charge. This offer came about because the force of the air from the registers, when combined with the new ducting, is significant and I expressed some comfort related concern to the salesman and installers. There is no additional labor charge because the switch must be made regardless. Im tempted but I cant decide if the VS is worth the up charge. Just how much nicer is that 3-stage VS furnace? Id love to list the price for this equipment upgrade but realize pricing is against the forum rules.

Really appreciate any and all feedback.
