Ac not cooling he tried turning it on a couple times at the breaker but it wouldn’t start. When we arrived we checked voltages and found only one leg of power going to the unit. When we tried to open up the disconnect to check voltages it sparked and smoked. When we got it open we found a breaker terminal broken. Turned off at the breaker inside and wire nutted it outside. Talked to the owner and he wants to replace the disconnect and he wants a cleaning done on the ac as well. Office will call to make the appoiments. Thanks Brad
