Whole House Generator Installation Bohemia

What Happens When Your Power Actually Stays On

You know what it’s like when a nor’easter rolls through Bohemia and the lights start flickering. That pit in your stomach wondering if this is the one that knocks you out for days. Wondering if your basement’s going to flood because the sump pump died. Watching hundreds of dollars of food spoil in your fridge while you’re scrambling to find a hotel that still has rooms.

A whole house generator installation in Bohemia, NY changes that completely. The power goes out, and within 10 seconds your generator kicks on automatically. No running outside in the storm. No extension cords. No decisions to make.

Your home stays warm. Your sump pump keeps working. Your fridge stays cold. Your family stays comfortable. You’re not one of the 600,000 Long Islanders sitting in the dark for two weeks like after Hurricane Sandy.

That’s what a home standby generator installation actually does. It removes the entire problem from your life. The storms still come through Suffolk County, but you stop worrying about them the same way.

Generator Installation Process Bohemia

Here's Exactly What Happens Start to Finish

First, we come out to your Bohemia property and figure out what size generator you actually need. That depends on what you want to keep running—whole house or just critical circuits like heat, fridge, sump pump, and a few outlets. We look at your electrical panel, your fuel source, and where the generator’s going to sit.

Then we give you a price. One number that includes the generator unit, the transfer switch, all electrical and gas line work, the concrete pad, permits, and inspections. If that number works for you, we get on the schedule.

Installation typically takes one to two days. We pour the pad, set the generator, run the gas line from your meter or propane tank, install the transfer switch inside, wire everything to your panel, and test the whole system. Then we handle the permit inspections with the town and get you signed off.

When we’re done, you’ve got a Generac or Kohler generator that monitors your power 24/7. The second your power drops, it fires up automatically. When PSEG restores power, it shuts back down and goes back to standby mode. You don’t touch anything.

What's Included in Your Generator Installation

Your whole house generator installation in Bohemia, NY includes everything you need to go from no backup power to fully automatic protection. That means the generator itself—we install Generac and Kohler systems sized correctly for your home. It means the automatic transfer switch that detects the outage and switches your house over to generator power in under 10 seconds.

We run the fuel line, whether you’re on natural gas through National Grid or you’re using propane. If you’re on propane, we’ll help you size your tank so you’ve got enough fuel to run for a week or more during an extended outage. We pour the concrete pad and set the unit on a stable base that meets code. We pull all permits with the Town of Islip and handle all inspections.

In Bohemia and throughout Suffolk County, whole house generator cost typically runs between $7,000 and $12,000 for most homes, depending on size and fuel type. That’s less than what a lot of families spent on hotels, spoiled food, and emergency repairs during just one major storm. And it’s a one-time investment that increases your property value and removes the power outage problem completely.

The system runs on your existing natural gas line or a propane tank. It tests itself weekly to make sure it’s ready. And when the power goes out—whether it’s a summer thunderstorm or a winter blizzard—it’s already working before you even notice the lights went out.

How long does a whole house generator installation take in Bohemia?

Most home standby generator installations in Bohemia take one to two days from start to finish. Day one is usually the heavy work—pouring the concrete pad, setting the generator, running the gas line, and installing the transfer switch inside your home. Day two is wiring everything to your electrical panel, testing the system, and making sure it’s running correctly.

If we need to trench a longer gas line or if there are complications with your electrical panel, it might stretch into a third day. But for a typical Bohemia home with straightforward access and an up-to-code panel, you’re looking at two days of work.

After installation, we schedule the permit inspections with the town. Those usually happen within a week or two depending on the inspector’s schedule. Your generator is fully functional as soon as we finish the install—the inspection is just the final sign-off.

What size generator do I need for my house in Bohemia?

It depends on what you want to keep running during an outage. If you want true whole home coverage—central air, electric dryer, every outlet, every light—you’re typically looking at a 20-22 kW generator for most Bohemia homes. That’ll run you somewhere in the $12,000-$15,000 range installed.

If you’re okay with just the essentials—heat, hot water, fridge, freezer, sump pump, some lights and outlets—you can usually get away with a 10-14 kW unit. That brings the cost down to the $7,000-$10,000 range for the full installation in Bohemia, NY.

We figure this out when we come to your house. We look at your electrical panel, add up the load of what you want to protect, and size the generator accordingly. Most Suffolk County homeowners go with the mid-range option—enough to stay comfortable and safe, but not necessarily running the pool heater and every appliance at once.

Do I need natural gas or can I use propane for my generator?

Either one works. If your Bohemia home already has natural gas service, that’s usually the easiest route. We tap into your existing gas line, and you’ve got unlimited fuel as long as the gas supply stays on—which it almost always does even when electric goes out.

If you’re not on natural gas, propane is your option. We’ll connect your generator to either your existing propane tank or help you size a new one. A 500-gallon propane tank can run a typical whole house generator for about a week straight. A 1,000-gallon tank gets you two weeks or more.

Most homes in Bohemia have access to natural gas, so that’s what we install most often. But propane works just as well—it’s just a matter of making sure you’ve got a big enough tank and keeping it filled before storm season. Either way, you’re getting the same automatic backup power when the grid goes down.

How much does a Generac whole house generator cost in Bohemia?

For a complete Generac whole house generator installation in Bohemia, NY, you’re typically looking at $7,000 to $15,000 depending on the size of the unit and your home’s setup. A smaller 10-12 kW Generac that covers your essentials usually runs $7,000-$9,000 installed. A larger 20-22 kW unit that powers your entire home including central air runs $12,000-$15,000.

That price includes the generator itself, the automatic transfer switch, all electrical work, gas line connections, the concrete pad, permits, and inspections. It’s a turnkey number—we’re not hitting you with surprise charges after the fact.

The cost varies based on how far we need to run the gas line, whether your electrical panel needs any upgrades, and which Generac model makes sense for your home’s power needs. We give you the exact price upfront after we assess your property. No guessing, no estimates that change later.

Will a generator increase my home's value in Bohemia?

Yes. Backup generator installation is one of the most popular home improvements in Suffolk County, and it’s something buyers specifically look for after they’ve lived through a major outage. When you’re selling a home in Bohemia and you can tell buyers they’ll never lose power during a storm, that’s a real selling point.

You’re not going to recoup 100% of the installation cost when you sell, but you’re also not installing it just for resale value. You’re installing it so you don’t lose a week of your life every time a nor’easter comes through. The increased property value is just a bonus on top of 10-15 years of never worrying about power outages again.

Real estate agents in Suffolk County will tell you the same thing—homes with whole house generators sell faster and often for more than comparable homes without them. Buyers know what it’s like to sit in the dark after a storm. They’ll pay extra to avoid that.

Do you handle the permits and inspections for generator installation in Bohemia?

Yes, we handle all of it. Generator installations in Bohemia require permits from the Town of Islip, and they require inspections after the work is done. We pull those permits, we schedule the inspections, and we deal with the town directly. You don’t have to do anything.

This is part of why you hire a licensed electrical contractor instead of trying to DIY it or using an unlicensed installer. The permit process ensures the work is done to code, the gas lines are safe, and the electrical connections won’t cause problems down the road. Inspectors check our work, sign off on it, and you’ve got documentation that everything was installed correctly.

If you ever sell your house, that permit history matters. It shows the next owner that your backup generator installation was done legally and safely. And if you ever need service or repairs, any licensed electrician can work on it because it’s a documented, code-compliant installation.
