We’re factory-certified Generac installers with over 90 years of continuous service in this region. That combination of trade depth and local history means every generator project is handled under one roof, from the electrical panel to the fuel connection to the final load test.

Generator Installation in Bergen County

A standby generator installation draws on more than one trade. The job involves a natural gas or propane connection, an automatic transfer switch that disconnects your home from the utility grid during an outage and reconnects it when power returns, electrical panel work, and local permitting. Our team handles all of it. Licensed electricians, plumbers, and HVAC technicians work together on every installation rather than passing the project between separate contractors.

We install both partial-home and whole-house Generac standby generators, sized to your actual needs. Whether the goal is keeping pipes from freezing during a February outage or maintaining complete, uninterrupted power for a commercial facility, we help you choose the right system before any equipment is ordered.

Generator Repair for All Makes & Models

We service all makes and models, including units we didn’t install. Common failure points include transfer switch faults, battery degradation, fuel delivery problems, and control board errors. Our licensed electricians and trained technicians can diagnose and repair electrical faults, fuel system issues, and control failures across generator brands.

Our 24/7 emergency response covers generator repair. If your unit fails to start during an active storm outage, we can dispatch. With more than 150 employees, we have the team depth to respond during high-demand periods when calls spike simultaneously across Northern New Jersey.

Generator Maintenance That Keeps You Ready

Generac recommends annual professional maintenance for home standby generators. A full service visit typically covers oil and filter changes, spark plug inspection, battery testing, load testing, and a complete system check. Even units that run a weekly self-test cycle need that annual professional service to catch wear, fuel system issues, and electrical degradation before they cause a failure-to-start event during an actual outage.

We offer maintenance agreements that keep your generator on a regular service schedule, alongside your HVAC systems if applicable. We service all makes and models, so existing generator owners don’t need to switch equipment to work with us.

Emergency Generator Service, Around the Clock

Generator failures tend to happen at the worst possible moment: during the outage itself, when a unit that hasn’t been properly maintained can’t start under load. Our 24/7 emergency response covers generator and HVAC needs across Bergen County and the surrounding region, and our 150-plus-person team gives us the depth to dispatch when demand spikes simultaneously across Northern New Jersey. That moment calls for a technician who can work safely on fuel systems and electrical components under field conditions. That’s what we send.
