Other than a loss of freon, an A/C failing to work IS and electrical issue. The electrical issue may be internal to the unit itself such as: shorted or open compressor winding= electrical issue, blown start/run capacitor= electrical issue, low voltage thermostat circuit/fuse blown= electrical issue, circuit board failure= electrical issue. The OP may very well find his problem outside of the A/C unit itself, but there is no smoking gun here that says to eliminate looking for the problem under the A/C bonnet.
