Hvac troubleshooting questions for free
I'm trying to help my neighbor (single mother of 2). I am fairly knowledgeable of electricity flow, voltage, capacitors, relays and such. She has an American standard HVAC. Her AC works fine. However when the heat is turned on after a few minutes the A/C also kicks on and trips her circuit breaker. I checked for burnt/loose/coroded wires. The breaker doesn't get hot. I don't know a lot about HVAC units and not sure that both should kick on or not (seems a little odd to me, to be a able to heat that the AC turn on).
