Got questions about installing or maintaining a Generac generator? Our highly trained team is here to provide expert answers—whether it’s a quick question or a detailed discussion. Let’s find the perfect solution for you!
Let's Get Started

Get the Unbeatable Protection of a Generac Generator!

When the power goes out, your Generac standby generator turns on automatically—usually within seconds—so your home stays safe and comfortable. That means your heat or A/C, refrigerator, sump pump, Wi-Fi, lights, and essential systems can keep running without you doing anything.

Unlike portable generators, a standby generator is permanently installed, starts and stops on its own, and runs on your home’s natural gas or propane—so there’s no refueling, no extension cords, and no scrambling during a storm.

Choose the Right Level of Backup Power

Generac standby generators range from 10–28kW, supporting homes from about 1,000 sq. ft. to 6,000+ sq. ft. depending on what you want to power. We’ll review your needs and design the right solution for your home and budget:

    • Essential Power Coverage – Keeps the most important circuits running (like heat, fridge, sump pump, and some lights).

    • Whole-Home Backup – Powers most or all of your home for the most seamless “business as usual” experience.

    • Managed Whole-Home Backup – A flexible middle-ground that uses Generac load management to deliver near whole-home coverage with a smaller generator—balancing comfort, performance, and cost.

We Handle Everything

We manage the entire process for you, making generator installation simple and stress-free.

    • Financing options available (if needed) — terms from 12 months up to 12 years.
    • Right-size your generator based on your home and priorities.
    • Determine the best generator location for safety, performance, code compliance, and ease of service.
    • Handle permits and utility/gas coordination.
    • Professional installation of the generator, transfer switch, and all connections.
    • Full testing and inspection support so it’s ready for real outages.
    • Ongoing service and maintenance, with optional remote monitoring and annual tune-ups using genuine Generac parts.

Why Choose a Generac Standby Generator

  • Automatic operation – Your generator senses an outage and turns on automatically—then shuts off when utility power returns. You’re protected whether you’re home, at work, or away on vacation.

  • No refueling – It runs on your home’s existing natural gas or propane supply, so you’re not dealing with gas cans, refills, or long lines during storm season.

  • Safe, direct power – A professionally installed transfer switch feeds power straight into your electrical panel, eliminating extension cords and reducing the risk of unsafe backfeeding.

  • Strong warranty options – Choose 5-, 7-, or 10-year coverage options for added confidence, with support available if your generator needs service.

  • Added home value – Standby power is a major selling point for buyers who want reliability, comfort, and protection for essential systems during outages.

Why Backup Power Is Essential in Rumson, NJ

Rumson homeowners face elevated outage risks due to coastal storms, wind exposure, salt air conditions, and regional utility disruptions. Over the past decade, Monmouth County has averaged multiple power outages per year, with coastal events often causing longer-than-average restoration times.

Power outages can affect:

  • Heating and cooling systems

  • Refrigeration and wine storage

  • Home offices and connectivity

  • Security, gate, and surveillance systems

  • Medical or lifestyle-critical equipment

A Generac standby generator restores power automatically—protecting your home, property, and peace of mind.

Generator FAQs for Rumson Homeowners

Can a generator be installed discreetly on a Rumson property?
Yes. Placement takes sightlines and landscaping into account alongside the required clearances, so the unit sits where it is least visible while still meeting setback and ventilation requirements.

Are generators practical for older Rumson homes?
Yes, though older electrical panels sometimes need updating before a transfer switch can be added. That is identified during the site visit so it forms part of the quote rather than appearing later.

What happens if the power is out for several days?
A standby generator is built to run continuously for extended outages, not just brief ones. On natural gas the fuel supply is uninterrupted; on propane, run time depends on tank size, which is why the tank is sized alongside the generator.
