Yes - although if you have 2 units, each will likely be a bit cheaper as they will be smaller units (saves maybe $50 - $100 per half tonne).
While we initially looked at and got quoted for 1 furnace (top floor only, bedrooms), we are leaning to two as we have 3 full storeys of south exposure (non-stop sun all day) windows. One 1.5-2ton unit likely could keep the bedrooms cool, but wouldn't make much of a dent on the rest of the house.
