Is it true that 110 VAC air conditioners waste more electricity than a 220
VAC unit?

Thanks in advance

Yes - assuming everything else is equal, the 110VAC unit has
approximately double the current flow and thus a greater heat loss in
the wiring.


This is Turtle.

But only if the wires are too small [ at upper limit of the NEC code], too long, or defective. Heat lost as you speak of it is only
present [ in a measuriable amount ] when the wires are not big enough or at the upper limit of the power draw of the wires but still
inside the upper limits of the NEC code.

What the original poster is thinking about is not the heat lost of the wire , but is the 220 volt service pulling 4.5 amps and the
120 volt service pulling 9 amps. The ideal of paying for two hot wires is the problem as people think 220 volt service cost less.
