Multi-Zone Furnace versus 2 Furnaces - need input
I am building a 2500 sq ft, 2 story house and the builder is giving me 2 options for furnaces:
1) A Multi-Zone furnace, allowing me to control my basement, main, 2nd floor individually - each floor with its own thermostat
2) 2 Furnaces, one furnace for the basement and main, one furnace for the 2nd floor
Does anyone know the pro's and con's of 1 versus 2? There is not charge for either option.
Air Conditioning is also a concern - what will the above have on A/C?
