Relocating central air conditioner coolant supply line
Yes, you can do that. Technically, you can have the condenser unit anywhere you want. You just need a pathway for the freon supply line and the electric lines. Ideally, the closer the air handler and condenser unit are, the better the cooling will be so that needs to be a factor. If you're moving everything around, you might want to consider getting the air handler out of the attic.
