Currently I have a Carrier Infinity 2 Stage Variable Speed Gas furnace with 2 Speed Infinity 18 Air Conditioner. If some day I decide to upgrade to the two speed Heat Pump what else may need to be replaced besides the outdoor unit? Lineset? Evap coil? Would this be a fairly simple labor job for a service tech?
Last Question: What would become of my 1 year old 38TDB? Is it possible the dealer would want to buy it back (real cheap)?
Would like to replace 38TDB with 38YDB or next year's more efficient model. With gas prices getting higher I'd like to check my options.
