re: So how many kW does a 2 ton ac use?

I have a 2.5 ton heat pump. My Ridgid 6800/8000 Watt generator will run the A/C, fridge, freezer, television, DISH receiver and a couple of lights. The lights dim and the DISH receiver resets every time the A/C kicks on.

I just bought the Westinghouse 12,000/15,000 generator and only turn off the breaker for the electric water heater and range when it is running. It handles the rest of the house like a champ. Gas, on-demand water heater and gas range are on the way.
