Cost to run central A/C
A couple of years ago, I hooked up an amprobe to my 3 ton carrier unit
outside and it read 16 amps (220V).
My inside fan blower I think used 5 amps (120V).
So that's about 4,120 watts total full load. Keep in mind I usually
keep my inside fan on continuosly, and my outside unit cycles on and
off throughout the day.
