    A ductless mini split is the best option IMHO. The indoor section is away from where the kids could put stuff in it as they are want to do. And it is the quietest and most energy effecient.

    2 Zones

    One thing to look for in the price difference is if anyone is offering a load calculation for your new system. I also would suggest zoning the 2 stories so the temps can be independently controlled.

    Up here in this corner of Wa. state, we find heating with heat pumps is less expensive than gas. I would suggest the Carrier Infinity system sized to match the manual J calculation.
