Why Our Repairs Stand Out

We Service What We Sell—And More

At John Nugent & Sons, our commitment to quality extends beyond installation. Our technicians are factory-trained and certified, possessing deep knowledge of a wide range of generator systems. This expertise allows us to quickly identify the root cause of any problem, saving you time and preventing repeat issues. We handle everything from routine maintenance checks to complex electrical and mechanical repairs.

We believe in transparent service and lasting solutions. Before any work begins, we provide a clear explanation of the problem and a detailed estimate. We use only OEM or superior-quality replacement parts to ensure every repair enhances your generator’s performance and longevity. With our meticulous approach, you can be confident that your backup power system is in the most capable hands.

Seamless Backup Power

Expert Home Generator Installation

A whole-home standby generator is the ultimate solution for protecting your home from power outages. Unlike portable units, a standby generator is permanently installed and wired directly into your home’s electrical panel. It activates automatically within seconds of an outage, restoring power to your lights, appliances, and HVAC systems seamlessly, whether you’re home or away.

Our comprehensive installation process ensures your new generator is perfectly suited to your needs. We start with a thorough assessment of your home’s power requirements to recommend the right size and model. From securing permits to the final system test, our licensed electricians handle every detail with precision and care, guaranteeing a safe, compliant, and reliable installation.

The Perfect Fit For Your Home

Customized Power Solutions

Choosing the right generator is critical for effective backup power. A system that’s too small won’t power your essential circuits, while one that’s too large is inefficient. Our experts take the guesswork out of the equation. We analyze your household’s energy consumption, considering everything from your A/C unit to your medical equipment, to design a solution that provides complete coverage without waste.

We partner with leading generator manufacturers to offer a selection of the most reliable and technologically advanced systems on the market. Our team will guide you through the options, explaining the benefits of different fuel types (like natural gas or propane) and features. Our goal is to equip your home with a customized, cost-effective generator that delivers unwavering performance.

Always Be Prepared

The Unmatched Peace of Mind of Automatic Power

The primary benefit of a professionally installed standby generator is the complete peace of mind it provides. You no longer have to worry about the next storm forecast or wonder if you’ll have power when you return from a trip. Your generator is always on guard, ready to take over the moment an outage is detected.

This automatic protection is crucial for maintaining your family’s safety and comfort. It keeps the lights on, the refrigerator running to prevent food spoilage, and the sump pump working to prevent flooding. For those who work from home or have family members with medical needs, this uninterrupted power is not just a convenience—it’s essential.

Furthermore, a standby generator operates automatically. There are no extension cords to run in the dark or heavy equipment to refuel in bad weather. The system manages itself, performing weekly self-tests to ensure it’s always ready. This hands-free reliability means your home and family are protected 24/7, regardless of the circumstances.

A Smart Investment

Protecting Your Property and Its Value

Beyond immediate comfort and safety, a whole-home generator is a smart investment in your property. Power surges and sudden outages can wreak havoc on sensitive electronics, from your computers and televisions to your smart home devices. A generator with a high-quality automatic transfer switch helps protect these valuable assets from damage.

In addition, a permanently installed generator can significantly increase your home’s resale value. It’s a highly sought-after feature for potential buyers, especially in areas prone to power disruptions. This feature signals that a home is well-maintained and prepared for emergencies, making it more attractive on the market.

Finally, a generator can help you avoid the hidden costs of a power outage. This includes expenses like hotel stays, spoiled food, and basement water damage from a failed sump pump. By investing in a reliable backup power solution, you’re not just buying a piece of equipment; you’re investing in the long-term protection and value of your home.

We Have Answers

Frequently Asked Questions About Home Generators

Choosing, installing, and maintaining a generator can bring up a lot of questions. We’ve compiled answers to some of the most common inquiries we receive from homeowners in Northern Virginia to help you make an informed decision.

What size generator do I need for my house?

The right size depends on what you want to power. A smaller generator might cover essentials like the refrigerator and lights, while a larger one can run your entire home, including the A/C. We perform a detailed load calculation to recommend the perfect size for your specific needs.

How does a standby generator work?

A standby generator is connected to your home’s electrical system through an automatic transfer switch. When it detects a power outage from the utility, the transfer switch automatically disconnects your home from the grid and starts the generator, restoring power in seconds.

How often does my generator need maintenance?

We recommend professional maintenance at least once a year to ensure your generator is ready for an emergency. Regular service includes changing the oil and filters, checking the battery, and running a diagnostic test to confirm everything is in proper working order.

What's the difference between a standby and a portable generator?

A standby generator is a permanent installation that runs automatically and can power your entire home. A portable generator is smaller, must be manually started, and can only power a few items at a time via extension cords. Standby generators are a safer and more convenient solution.

How long does installation take?

A standard installation typically takes one to two days, depending on the complexity of the job, including the placement of the unit and the fuel line connections. We handle all permits and inspections to ensure a smooth process.
