Resetting an outside AC breaker can be a daunting task, especially if you have never done it before; however, it is actually quite straightforward. The first step is to locate the main circuit breaker. This breaker will usually be located on the exterior wall of your home near where the outdoor unit attaches to your house. Once you have found this switch, make sure that all power to the exterior unit has been shut off by turning off both breakers in this area - one for your interior HVAC and one for your outside air conditioner. Next, find a flathead screwdriver and use it to carefully remove any screws holding down the cover plate of the AC breaker box. Then, press either an up or down arrow (depending on which type of reset system you're using) until you hear two clicks and then release pressure from both buttons simultaneously while still pressing them inwards slightly - this should cause a reset sound inside of the box indicating that it was successful. Finally replace everything back into its original place and turn both breakers back on - now your outside AC should be operational again!
