I accidentally short the c wire and both units not turning back on

after a few tips from @ThreePhaseEel I be able to fix the problem that I'm having. after I short the circle on a furnace and blow off the fuse. Since I'm not a AC tech so I don't know much about a ac or a heat pump. beside the unit outside that they need a furnace unit inside as well. so the problem that I'm having with out knowing that so I'm not be able to located the furnace. since @ThreePhaseEel mentioned that the furnace should be under the attic so I went up there to found the furnace with a fuse blow off. so replace it with a new one. Tada! it works. what I learned here that. even you cut the power off on the AC to put on a new thermostat that the power the fed to a furnace might come from the different source. so make sure to cut the power off from the attic as well. or I should protect the C wire at all cost so it won't touch any other cable and I should be good. sorry about my bad english. this is the best I could do to answer to my own problem. cheers.
