What You Get With a Home Standby Generator

Power outages in Suffolk County aren’t just inconvenient anymore. They’re longer, more frequent, and they hit at the worst possible times. Suffolk County ranks 7th in New York for total outages and percentage of customers affected. When the next storm rolls through, you don’t want to be scrambling for flashlights or tossing hundreds of dollars of food.

A whole house generator installation in Lindenhurst, NY means your home keeps running automatically. No extension cords. No manual startup. No waiting in the cold while your sump pump sits silent and your basement floods.

The generator senses the outage within seconds, kicks on by itself, and powers your essentials—or your entire home, depending on what you choose. It runs on natural gas or propane, so you’re not rationing fuel or making runs to the gas station. When utility power comes back, it shuts itself off and goes back on standby.

You’re not just buying equipment. You’re buying the ability to ignore the outage entirely.

Here's How a Generator Install Actually Happens

First, we come out and give you a free estimate. We’ll look at your electrical panel, figure out what you want to keep running during an outage, and recommend the right size generator. For most homes in Lindenhurst, that’s a 14kW to 22kW Generac whole house generator. If you just want the essentials covered—fridge, furnace, lights, outlets—a 14kW or 16kW unit works. If you want central air and the whole house running like normal, you’re looking at 20kW to 22kW.

Once you approve the estimate, we handle the permits and schedule the install. We’ll set the generator on a concrete pad outside your home, run the fuel line (natural gas or propane), and connect it to your electrical system with a transfer switch. That switch is what tells your home to pull power from the generator when the grid goes down.

The whole install typically takes one to two days, depending on your setup. When we’re done, we test the system to make sure it fires up correctly and transitions smoothly. Then we walk you through how it works—though honestly, you won’t need to do much. It’s fully automatic.

What size generator do I need for my home in Lindenhurst?

For a typical Lindenhurst home—around 2,000 square feet—a 14kW to 22kW Generac whole house generator is usually the right fit. If you only care about keeping the essentials running during an outage (lights, fridge, furnace, a few outlets), a 14kW or 16kW unit will handle that.

If you want to run your whole house like nothing happened—including central air conditioning, multiple appliances, and all your outlets—you’ll want a 20kW or 22kW generator. That gives you the capacity to power everything without overloading the system.

We’ll assess your electrical panel and your priorities during the estimate. There’s no point in oversizing a generator you don’t need, and there’s definitely no point in undersizing one that leaves half your house dark.

Do I need a permit for a home generator installation in Lindenhurst?

Yes. Any home standby generator installation in Lindenhurst, NY requires a permit from the town. That covers both the electrical work and the gas line connection. It’s not optional, and it’s not something you want to skip.

We handle all the permitting as part of the installation. We pull the permits, schedule the inspections, and make sure everything is up to code. You don’t have to deal with the town or chase down paperwork.

Skipping permits might save a few bucks upfront, but it’ll cost you later—either in fines, insurance issues, or problems when you go to sell your home. We do it right from the start.

Will a backup generator run my whole house during an outage?

It depends on the size of the generator you install. A properly sized whole home generator installation in Lindenhurst, NY can absolutely run your entire house—lights, appliances, HVAC, outlets, everything.

If you go with a 20kW or 22kW Generac unit, you’ll have enough capacity to power central air conditioning, your refrigerator, your furnace, and all the other loads in your home at the same time. It’s designed to handle the startup surge when motors kick on, so you’re not tripping breakers or losing power mid-cycle.

If you choose a smaller unit (14kW or 16kW), you’ll be able to run the essentials, but you might need to be selective about what’s on at the same time. We’ll map that out during the estimate so you know exactly what to expect.

How does a home standby generator work during a power outage?

A home standby generator monitors your utility power constantly. When it detects an outage, it starts itself automatically—usually within 10 seconds—and begins powering your home through a transfer switch. You don’t flip any switches or go outside. It just happens.

The transfer switch is what makes it seamless. It disconnects your home from the utility grid and connects it to the generator instead. That prevents backfeeding, which is dangerous for line workers and your equipment.

The generator runs on natural gas or propane, so it doesn’t need refueling like a portable unit. It’ll keep running until utility power is restored—whether that’s two hours or two weeks. Once the grid is back, the generator shuts itself off and returns to standby mode.
