Ironically, I just got a quote on a 22W Generac whole house generator. I have natural gas. Unit plus install is $11,500. And now power is out from this storm!
We got hit pretty hard here in LI and nobody has power. I can hear all my neighbor's generators going on all night which is killing me! I'm definitely doing this as I can't stand not having power. With potentially more storms and the winter coming up, I think it will be a worthwhile investment.
