>2 air conditioners & 2 furnaces??

If one furnace is out of service, the costs go really high using the other because some rooms end up really warm before other rooms are comfortable. Not because one furnace is inherently better than two or vice versa. One ...

The alternative would be to put dampers in each one and just close the damper when the unit is not in use.

My vote is for 2 systems. One system + zoning controls will need just as much maintenance as 2 separate systems.

With 2 systems if one fails you can live in the other part of the house until you get it fixed.

>Multiple furnaces on 1 ckt.
424.3A goes on to discuss "branch circuits supplying two or more outlets for fixed space-heating equipment."

So, the inference that 'equipment,' as used in 422, cannot be limited to one piece of equipment.
