I'm planning on getting a humidifer installed in my house (~3300sq ft). My current setup is that there are two furnaces/zones. One for the top floor and one for the middle floor (basement unfinished)
My HVAC contractor says its up to me if I want to get one Aprilaire 600 installed or to put one on each furnace. I'm thinking of getting one on each furnace even though one humidifer is said to be fine for houses even larger - is this overkill?? or will one humidifer work across the entire house effectively??
