A/C Unit

I purchased a 240 volt A/C unit. I have it on its own circuit on a 20 Amp breaker, the wire size I have is 14/2. The problem I am having is that there are only 120volts going to that outlet. How do I increase the voltage to what I need to run the A/C unit?

You are going to need to run a new number 12 wire just for this unit right to the panel.

14/2 is a fire hazard on a 20-amp circuit.

However 12/2 can be used to provide 240 volts if connected to a double-pole 20-amp 240-volt breaker in the panel. You'll also need a 20-amp 240-volt receptacle.

Do you have much electrical experience? Did you run this A/C circuit yourself?

A/C Unit

Thank you for your quick repies. It won't be too hard to re-run the wire. I've had some experience wiring in outlets and switches, I just haven't had to wire in a 240 volt device before. I am going to use the circuit that was used for my old swamp cooler, so all I am going to do is re-route the circuit to where the A/C unit is. Just a side note. The A/C unit is a window mount unit. Thanks again, Mike
