When you submit this form, your request goes to a local electrician or generator installer who works in your area. They will reach out by phone or email, ask some questions and, if it fits, arrange a visit and a written quote. It is free, and you are not committing to anything.
Good details to add: gas service or not, one- or two-family house, panel size if you can see it on the main breaker, which things matter most to keep running, and for a repair, the brand and the code on the display.
