Does someone know what the Amp Draw is on a 3.5 ton 13 seer unit?

The fan on my AC unit malfunctioned a few years ago.My electric bill increased every month until it was almost double what it had been.I checked my main panel today because my electric bill is increasing.

The readings were on one leg and the other leg.When the AC was turned on, the 4.5 and 3.5 Amp legs jumped to 20 and 13.5 Amps, respectively.The air handler is not on the leg that jumped up to 20.5 Amps, so something is pulling that leg up higher than the other.

I'm not sure what I need to read at the unit to get the readings for the fan motor and compressor, but I guess I have to.

I would check the draw at the unit to see if it was normal.There is a data tag on the outside of the unit.The values for the fan motor and compressor will be listed.Go by using those values.The listed value should not be exceeded by the motor or compressor.If the home is hot, you might have excess draw until it cools off a bit.The same can be said for your indoor unit, which will have a data tag as well.

Before looking at the Amp draw while the unit is running, you need to determine where the 4.5 Amp is being consumed without unit running.The equipment is poorly grounded and somthing has gone to ground.There would be an electrocution danger if that was the case.Get that 4.5 Amp first.
