Well, it says that my 3 ton rheem compresser draws about 22 amps, is that total or about 22 on each 120 line
11 amps on each 120 volt side??

No. 240 is rated differently since you are using 2 phases. Simply speaking, 19 comes in 1 phase and is returned on the other. Remember there is no neutral like 120.

So? Is a 220 3 ton a/c using a total of 19 amps? So that is cheaper to run then say 4, 8000 window units that use about 6 amps each, total of about 24?
Basically, is it really cheaper to use 220 units? Thanks, richard

You really cant compare the two. What would you do for heat? Where is the cold air in the basement coming from?
