I think you are missing one set of numbers which would be the blower which moves air through your duct system. This will be either in a utility room in your home, the attic, or like me the crawl.

A simple wattage calculation is amps times volts = watts. You can get a little more complicated than that if you factor resistance across the wire, but a quick down and dirty is simply amps x volts.

Heavy equipment in your home will run on 220 volts (from 208 and 240 depending on your power company, their consistiency, and the time of day). No kidding, power companys used to anyway, drop voltage during non peak hours like at night.

Your compressor looks to 'draw' 17.2 amps. 17.2 x 220 equals 3784 watts. If you run this for an hour, it will draw 3.784 kilowatt hours. Good thing the compressor cycles on and off and doesnt run constantly. Where I live 3.784 kwh costs about 40 cents.

Your compressor fan looks to draw about 1.6 amps or 352 watts. or about .35 kwh

Your minimum breaker requirement is different than the max breaker allowed. Yours probably is 30 or 40 amps.

Another example your 1500 watt hair dryer draws about 12.5 amps on your household 120 volt circuit. (1500 watts / 120 volts = 12.5 amps) If you ran it for 1 hour, it would draw 1.5 kilowatt hours and cost you about 15 cents or so. Electricity is cheap when you think about it, no?

BTW amps kills. It is a measure of force that can be converted to power. Think of a garden hose. The more water I FORCE through it, the more power I will feel at the nozzle.

You still need the amps and voltage of your evaporator/blower unit. I think you can do the math from here.
