Regardind Generator use:
If yours is capable of providing 208/220 volts of power:
When a big Ice storm hit back in western NY many years back and power was out, I cut the power line to the furnace and installed an electrical plug to it so it could run off the generator.
This can be done for your central A/C unit also. Check the outlets on your generator and head to the hardware store for a compatable extension cord(s) and a plug to attach to your A/C unit.
My generator is capable of running my entire house. I had my electrician install a gen-tran setup. I used it in 2002 when we had that huge blackout. I don’t mess around.
My fridge will keep my food cold and my ice cream frozen.
Come on Irene!
