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 Matters in Somerset County, NJ

Over the past decade, Somerset County homeowners have averaged 2–3 power outages per year, with outages most commonly caused by severe thunderstorms, winter storms, high winds, and fallen trees. Due to mature tree coverage and shared utility corridors, even localized storms can result in widespread outages lasting 12–48 hours or longer.

Extended outages in Somerset County can create serious disruptions, including:

- Loss of heating and cooling in larger homes
- Failure of sump pumps, increasing basement flood risk
- Disruption to home offices and remote work
- Refrigeration and food safety issues
- Interrupted operation of medical equipment and security systems

A Generac standby generator restores power automatically within seconds—keeping your home protected without refueling, extension cords, or manual operation. For many Somerset County homeowners, backup power is essential for maintaining comfort, safety, and daily routines during severe weather events.

Generator FAQs for Somerset County Homeowners

Do larger homes in Somerset County need bigger generators?
Not always. With proper load calculations and Generac load management, many homes can achieve near whole-home coverage without oversizing the generator.

Are generators recommended for homes with finished basements?
Yes. Backup power keeps sump pumps and dehumidifiers running, helping protect finished spaces from water damage.

Can Generac generators run on natural gas in Somerset County?
Yes. Most homes have access to natural gas, and Generac systems are designed for reliable NG operation.
