Generac Generator Installation in Virginia Beach, VA

Factory-authorized to install and warranty Generac standby generators, with training kept current.

We install Generac Guardian air-cooled standby units, sized to back up your whole electrical panel.

A load calculation sizes the unit, commonly a 24kW Guardian for a local home, not a guess.

A whole-home automatic transfer switch with Generac load management, so the unit is never overwhelmed.

We pull the permit, handle the gas or propane connection, and coordinate the Dominion Energy tie-in where the install requires one.

We set up Generac Mobile Link so you can check the generator's status from your phone anywhere.

The proven, best-selling home standby brand

Generac is the most-installed home standby brand in the country, which means a mature product, wide parts availability, and a strong local dealer and service network. That track record is a big part of why it is the brand most local homeowners ask for by name. We install the Guardian air-cooled line that covers the vast majority of homes here, and resale buyers recognize it as a real feature of the home.

Authorized-dealer warranty, parts, and support

Buying a Generac from a factory-authorized dealer is different from buying one from a contractor who installs whatever is cheapest. As an Authorized Dealer, we install to Generac's standards, register the warranty, and have the dealer relationship for parts and support, which becomes critical during a post-storm restoration when demand is highest. Your generator is backed by both the manufacturer's warranty and our workmanship warranty.

Automatic, hands-free operation that protects the home

A Generac Guardian with an automatic transfer switch senses the outage, disconnects your home from the grid, and starts within seconds, whether or not anyone is home. That automatic operation protects the home during a multi-day outage: the sump pump keeps the crawlspace dry, the refrigerator keeps its contents, and medical equipment stays powered. When the grid returns, it transfers back and shuts down on its own.

A typical whole-home Generac install

For a common 24kW Generac Guardian on a local home, installed pricing generally runs in the range of $10,000 to $20,000. That covers the unit, the automatic transfer switch, the pad, the connection, the permit, and commissioning. Larger Guardian units and demanding sites use the industry-average pricing for their size, which we quote to your specific situation.

What moves the price

The Guardian kilowatt size your home needs, whether you are on natural gas or need a propane tank set, the distance from the gas or propane source, the transfer switch type, and any panel upgrade required all move the number. We size the unit to your real loads, so you are not overpaying for capacity you will not use.

Every budget, done correctly

We install Generac systems for a range of budgets, and where a full whole-home standby is more than a homeowner wants, we can install a safe portable-and-interlock solution for essential circuits instead. What we do not do is cut corners on the parts that keep it safe and code-compliant, and we tell you honestly what each option gets you, so the decision is yours and there are no surprises on the invoice.

We were brought in by the contractor on a Tunnels to Towers Foundation project to install a whole-home standby generator for a local Navy SEAL's home, keeping a service member's home powered and protected. We are proud of the work, and we are installing another on a current Tunnels to Towers project in Virginia Beach.

Vicki had a whole-house generator installed and praised the excellent pricing and the very friendly, professional staff, saying she would highly recommend Castles Electrical. A straightforward, well-priced whole-home standby install done right, and exactly the kind of repeat referral our standby work is built on.

Real Customer Example | From a verified Google review (Vicki E., November 2024)

Two themes run through our five-star generator reviews: fair, affordable pricing and a crew that handles every detail with no surprise costs. Homeowners we have installed a whole-home standby for repeatedly point to both and say they would recommend us for a generator and for any electrical work at home.

Real Customer Example | What local generator customers tell us

The hurricane belt is why Generac sells here

This area has lost power in every major storm since Isabel in 2003, sometimes for a week, and that recurring risk is exactly why Generac standby generators are so common here. Homeowners buy a Generac to address a problem they have already lived through, and we size and install for the reality that an outage may last days, backing up the HVAC and sump pump for the long haul. Sizing for a multi-day event, not a two-hour flicker, changes what we recommend.

Authorized-dealer support proves itself after a storm

When a named storm hits, demand for generators and parts spikes across the region at once, and that is exactly when the difference between a factory-authorized dealer and a general installer shows. Our Generac dealer relationship means parts and factory support during those high-demand windows, which is when a homeowner most needs their generator backed by more than a one-person shop. A generator that goes down mid-storm is only as good as the support behind it.

Natural gas in the city, propane outside it

Fuel choice for a Generac depends on geography here. In the built-up parts of Virginia Beach, Chesapeake, and Norfolk, where natural gas is available, we install natural gas so there is no tank to refill. In rural Pungo, parts of Suffolk, and other areas outside the gas network, we set up propane. We match Generac's fuel to your address rather than defaulting to one answer.

Sizing a Guardian for a coastal home's loads

A typical local home with a heat pump, an electric water heater, a sump pump, and increasingly an EV charger or hot tub commonly lands on a 24kW Guardian for a 2,000-to-3,000-square-foot home. We run the load calculation so the Guardian is sized to your home's actual energy use, not a generic square-foot rule. We build in headroom for the EV charger or hot tub you may add next year, because upsizing after the fact is far more expensive than getting it right the first time.

Sizing the right Guardian model

Generac's Guardian air-cooled line runs from smaller units up through the 24kW and 26kW models that cover most local homes, with liquid-cooled units above that for the largest loads. We run a load calculation on your HVAC, water heating, well or sump pump, kitchen, and other major loads, then match the Guardian model to that number with headroom, so the unit carries your home during an outage rather than tripping trying to.

Whole-home ATS with Generac load management

We favor a whole-home Generac automatic transfer switch that backs up your entire panel, then use Generac's load-management modules to shed lower-priority circuits automatically when demand spikes. This gives you whole-home flexibility without oversizing the generator, a smarter and more economical approach than a basic essential-loads switch that permanently limits what you can run. In practice, you can still run the air conditioning, the well pump, and the kitchen, and the system quietly steps a large load back for a moment when they all start at once.

Fuel and gas-line capacity for a Generac

A Generac starves if the gas line cannot deliver enough volume at full load, a detail an installer focused only on the electrical side misses. We verify the natural-gas meter and line capacity, or size the propane tank and regulator correctly, so the Guardian gets the fuel it needs. An undersized gas supply causes the hard starts and shutdowns that leave a homeowner without power at the worst moment, so on propane, we also size the tank for realistic multi-day runtime and stable cold-weather pressure.

Commissioning with a real outage simulation

An installed Generac is not finished until it is proven, so we simulate an outage to confirm the automatic transfer works, verify the unit carries the intended loads, and set the exercise cycle. We would rather find a loose lug, a fuel-pressure issue, or a transfer-switch problem on a calm afternoon than have you discover it during a hurricane. The outage simulation is short, but it proves that every part of the system, from fuel to transfer to load, works together.
