The size of the furnace depends on the square footage of the house you are heating.

It depends on the rating of the furnace. There should be a plate or sticker somewhere on the furnace that shows the rating. If you are just powering a blower motor the rating will be lower than if you have an electric heating element.
Meet with your installer to determine the capacity of your new furnace. The furnace capacity should be matched with the size of the house. You want to get a furnace that heats a house without overheating the home. Because your furnace will be newer, it will take less energy to heat your home.
In order to properly size the wire per National Electric Code (NEC) standards you will need to know the amperage and the distance of the device (heater) from the source (circuit breaker panel). In order to know the amperage one would need to know the voltage since amperage changes inversely with voltage.
If you put a 85 amp breaker in there it will overheat from the starting and stopping of the motor. The extra size of the breaker insures that the furnace will run without interruption and without overheating the breaker. And electric motor can draw three times the amperage rated on start up momentarily. This is why there is need of extra amperage ratings.

It would all depend on the size of the compressor. If it's a small one(like for an airbrush gun) it might just work, but if it's a compressor to power impact wrenches or similar it'd probably not work.
