Generator Installation & Repair

Why Install a Backup Generator?

Long Island experiences frequent power outages from storms, hurricanes, and grid issues. A properly installed backup generator ensures your home or business remains powered when the grid goes down, protecting your family, property, and business operations.

Types of Generators We Install

Whole-House Standby Generators

Permanently installed generators that automatically start when power is lost. These systems are connected to your natural gas or propane supply and can power your entire home indefinitely.

• Generac Guardian Series - 11kW to 26kW, most popular residential models
• Kohler Residential Generators - Premium quality, quiet operation
• Briggs & Stratton - Reliable, cost-effective options
• Cummins Residential - Heavy-duty commercial-grade units

Portable Generator Transfer Switches

For homeowners with portable generators, we install manual transfer switches that safely connect your portable unit to your home's electrical system, eliminating dangerous extension cords.

Generator Installation Process

1. Free Consultation & Load Calculation

We assess your power needs, calculate required generator size, evaluate installation location, and recommend the appropriate system for your home or business.

2. Site Preparation & Permits

We handle all permits, coordinate gas line installation (if needed), and prepare the concrete pad or mounting location for your generator.

3. Electrical Installation

Our licensed electricians install the transfer switch, run electrical connections from your panel to the generator, and ensure all wiring meets code requirements.

4. Generator Setup & Testing

We install the generator unit, connect fuel lines, program the automatic transfer switch, and thoroughly test the entire system under load.

5. Training & Warranty Registration

We demonstrate system operation, explain maintenance requirements, and register your generator warranty.
