Should be a disconnect for it on the wall outside by the units. BTW, why did you disco the power to the whole structure? Was there a fire when you shorted out the feed to the A/C?
okay, this is where i am completely ignorant as to what i need to do....where is the other end? im assuming there is a box of some sort upstairs in the attic where the inside of the unit is located...man i have some investigating to do ... hahYou can actually fix the cut Red & White, or just swap the other colors, but make sure you do the same on the other end. Make sure first, before changing that they are at the other end in the air handler/furnace. You can also place against the lineset & tape to hold against the foam insulation, so that it does not happen again. They actually make a Panduit type PVC covering that you can use to cover the lineset, which helps in keeping damage to a min.
You can also use the beanies that have the gel in them, to fix the cut wire, without having to swap leads.
the gf went over my head and called someone out before i got a chance to look around more... said both the transformer and fuse crapped out and had some bad wires outside...$250 for his time/parts/labor etc... i doubt its anything that i really wanted to tackle or even could...IF you shorted out the wires while the unit was running, you may have blown a control fuse or transformer.
While this is an easy fix, it may be a bit complicated to find, especially when dealing with today's modern air handler units. You may have to call in an HVAC contractor for repairs....
