Air Handler And Condenser On The Same Circuit

I ve never seen that before but most of my systems are combo furnace ac.

Air handler and condenser on the same circuit.

One will be for the air handler and the other will be for the condensing unit. The high voltage wires from the air conditioner disconnect box usually mounted on an outside wall within arm s reach of the air conditioner unit are now pushed up through the wire clamp in the bottom of the box. The fan motor is mounted to the top lid of the condenser unit and turns on whenever the system has power. Of these the compressor is usually supplied by a 240v circuit and the air handler by a 120v circuit.

The high voltage wires have two insulated power wires and one bare copper ground wire. However it is infrequent for both to trip at the same time. They pull colder air in from the sides of the unit to cool the refrigerant running through the coils. The motor is responsible for spinning the fan blades which work to remove the hot air from inside the condenser.

Reader comments q a. That is unless you have a lightning storm or there is a power problem. Unfortunately yes you should replace your air handler and condenser at the same time if one or the other fails. Anyway they ran a 30a circuit up to the air handler and used the air handler as a j box and ran down to the condenser.

So both units are on the same circuit. When you purchase a new hvac system the efficiency ratings are based on matched equipment.
