You Get Real Backup Power That Actually Works

When the power cuts out, your generator kicks on in seconds. Not minutes. Not after you’ve already lost what was in the fridge or spent an hour looking for flashlights.

Your heating stays on in January. Your AC runs in August. Your security system doesn’t go dark. If someone in your home relies on medical equipment, it keeps running without you lifting a finger.

This isn’t about convenience. It’s about not dealing with the aftermath of an outage that lasts two days, or two weeks—which has happened here on Long Island more than once. Suffolk County ranks seventh in New York for power outages, and after Hurricane Sandy left over 630,000 people without power for up to 14 days, you already know what that looks like.

A whole house generator installation in West Hills, NY means your life doesn’t stop when the grid does. You’re not sitting in the dark hoping the utility company gets to your street soon. You’re already back online.

Backup Generator Installation Process West Hills

Here's Exactly What Happens From Start to Finish

First, we come out and assess your property. We look at your electrical panel, your natural gas or propane setup, and figure out what size generator you actually need based on what you want to keep running during an outage. That’s a free estimate, and it’s detailed—no guessing, no surprise costs later.

Once you approve the plan, we handle the permitting and schedule the installation. We set the generator on a concrete pad outside your home, connect it to your existing gas line or propane tank, and wire it into your electrical system through an automatic transfer switch. That switch is what makes the whole thing work without you doing anything—it detects the outage and switches your home over to generator power in under 10 seconds.

After everything’s connected and tested, we walk you through how the system works. You’ll also get mobile monitoring so you can check the generator’s status from your phone, anywhere, anytime. Then we clean up, pull permits for final inspection, and you’re set.

The whole process usually takes one to two days depending on the scope. And if anything ever goes wrong, we’re available 24/7 for emergency service.

Generac Whole House Generator West Hills, NY

What You're Actually Getting With This Installation

You’re getting a Generac home standby generator—the most reliable brand in residential backup power. These units are built to run on your existing natural gas line or propane supply, so there’s no refueling, no storing gasoline, no running outside in a storm to keep things going.

The system includes an automatic transfer switch that monitors your utility power and switches over the second it detects an outage. You won’t even notice it happen unless you’re paying attention. Everything you want powered—your HVAC, your refrigerator, your lights, your security system, your garage door—stays on.

In West Hills, NY, where the median home value is over $730,000 and most properties are large single-family homes, you’re protecting a serious investment. Frozen pipes from a winter outage can cost you tens of thousands in repairs. A failed sump pump during a storm can flood your basement. A whole house generator installation eliminates those risks entirely.

You also get mobile monitoring through Generac’s Mobile Link system, so you can check your generator’s status remotely. And depending on your insurance provider, you may qualify for a 3-7% discount on your homeowner’s premium just for having a standby generator installed. That adds up over time.

Most installations run between $8,000 and $16,000 depending on generator size and your home’s setup. Financing is available starting around $109 per month. And if you’re thinking about resale value, professionally installed generators typically return 100-150% of their cost when you sell.

How long does a home generator installation take in West Hills, NY?

Most home standby generator installations take one to two days from start to finish. That includes setting the concrete pad, running the gas and electrical connections, installing the automatic transfer switch, and testing the entire system to make sure it works correctly.

The timeline can vary depending on your property. If we need to trench a longer gas line or upgrade your electrical panel to handle the load, it might take a bit longer. We’ll tell you exactly what to expect during the free estimate so there’s no confusion.

Once the installation is done, we handle the final inspections and permitting. You don’t have to deal with the town or the utility company—we take care of that.

What size generator do I need for my home in West Hills?

It depends on what you want to power during an outage. If you want your entire home covered—HVAC, kitchen appliances, lights, outlets, garage door, security system—you’re typically looking at a 20kW to 24kW generator for most West Hills homes.

If you only want to back up essential systems like your refrigerator, heating, and a few circuits, you can get away with a smaller unit, usually in the 13kW to 16kW range. That costs less upfront but won’t keep everything running.

We assess your electrical panel and your actual usage during the estimate. We’re not trying to sell you the biggest unit possible—we’re trying to match the generator to what you actually need. Oversizing wastes money. Undersizing leaves you without power where it counts.

How much does a whole house generator cost in West Hills, NY?

A complete whole house generator installation in West Hills, NY typically runs between $8,000 and $16,000. That includes the generator itself, the automatic transfer switch, the concrete pad, all electrical and gas connections, permits, and labor.

Smaller generators that cover essential circuits cost less—closer to the $8,000 to $10,000 range. Larger units that power your entire home, especially if you have a bigger property or need a longer gas line run, can push toward the higher end.

Financing is available if you don’t want to pay the full amount upfront. Many customers finance for around $109 per month depending on the terms. And like we mentioned earlier, some insurance companies will discount your premium once the generator’s installed, which offsets part of the cost over time.

Do I need a permit for a generator installation in West Hills?

Yes. Any permanent home standby generator installation in West Hills, NY requires permits from the Town of Huntington. You’ll need electrical and building permits, and depending on your setup, possibly a gas permit as well.

We handle all of that for you. We pull the permits, schedule the inspections, and make sure everything is up to code before we’re done. You don’t have to go to the town building department or deal with any of the paperwork.

It’s also worth noting that a permitted, professionally installed generator adds value to your home and keeps you compliant with local codes. If you ever sell, the buyer’s inspector won’t flag it as an issue.

Will a generator run my whole house during a power outage?

It can, depending on the size of the generator you install. A properly sized whole house generator will power your heating and cooling, all your lights, your kitchen appliances, your well pump if you have one, and any other systems you want to keep running.

The key is sizing it correctly during the planning phase. We calculate your home’s electrical load and recommend a generator that can handle it. If you have a larger home or high-demand appliances like central air conditioning, electric heat, or a pool pump, you’ll need a bigger unit.

Some homeowners choose to back up only essential circuits to save on upfront cost. That’s fine too—we can set it up either way. But if you want true whole-home coverage during an outage, we’ll make sure the generator can handle it.

How often does a home standby generator need maintenance?

Generac recommends servicing your home standby generator once a year. That includes changing the oil and air filter, checking the battery, inspecting the fuel and electrical connections, and running the system under load to make sure everything works.

Most generators also run a self-test every week for a few minutes. You’ll hear it kick on briefly—that’s normal. It’s exercising the engine and checking that the system is ready to go if the power cuts out.

We offer maintenance plans if you want us to handle the annual service for you. It’s not complicated work, but it’s worth doing. A well-maintained generator will last 20 to 30 years. One that’s ignored might not start when you actually need it.
