Generator Installation

Standby Home Generator Installation

Long Island storms can knock out power for hours or days, taking your heat, your sump pump, and your refrigerator with them. A standby generator solves that. It detects an outage and powers your home automatically, so life goes on uninterrupted. As part of our home-services work, we size and install backup generators to fit your home and budget.

A generator keeps the rest of your system protected too, your heating system, your sump pump, and your essentials all stay running when the grid goes down.

Sizing & Install

Sizing and Installing Your Generator

The right generator depends on what you want to keep running.

Generators range from partial-home units that cover your essentials, heat, sump pump, refrigerator, and a few circuits, to whole-home systems that run everything automatically. During your free assessment we review your home's electrical needs and recommend the right size and fuel type, then handle the full installation, including the automatic transfer switch, to code.

Once installed, a standby generator starts on its own the moment the power fails and shuts down when it returns, with no extension cords and no hauling fuel in a storm.
