Generator Installation That Keeps the Lights On Through the Storm

Storms don’t announce themselves and outages don’t keep business hours.

The grid goes down across New Jersey several times a year, and when it does, the homes without backup power spend days waiting for the utility to restore service.

Princeton Air handles generator installation with licensed electricians, in-house gas line work, and proper sizing against the loads your household actually needs covered. After the install, outages become a non-event: the lights flicker once, the generator starts on its own, and the house keeps running until the grid comes back. Schedule your consultation online today.

What to Expect From Your Generator Installation

A standby generator is a bigger project than most electrical jobs, and the details matter.

A standby generator project includes plumbing the fuel line, wiring the transfer switch, and setting the pad. We move through four phases to get it all done right.

Your licensed electrician comes to the house and reviews the electrical panel, the available space for the generator and transfer switch, and the path for the fuel line. You share what loads you need to keep running during an outage, and that list shapes the sizing and the transfer switch configuration.

The generator pad gets set, the transfer switch gets mounted at or near the panel, the fuel line gets run from your gas supply, and the electrical tie-in gets completed to code. Your lawn, landscaping, and finished surfaces are protected through the work. Permits and inspections are handled as part of the job.

The generator is started, run through multiple cycles, and tested under load to confirm it handles the circuits you want covered. The automatic transfer switch is verified to activate and release cleanly. You get a walkthrough of the controls, the self-test schedule, and what to expect when an actual outage triggers the system.

Your relationship with Princeton Air doesn’t end at the install. You have a local team with more than 50 years of experience installing and maintaining electrical equipment across the region, and we’re the ones you call when anything comes up. Annual generator service keeps the unit ready to start the moment it’s needed, which is the entire point of owning one.

Responsive, knowledgeable, dependable, & honest. Thank you for getting out heat up & running!

Update:10/12/18
Chris S got the heat last year and remembered when he arrived today, asked if it had a problem since. He came back to do a PM on the heater and while he was waiting for me to arrive, he opened up the air conditioner to inspect it and saw the coils were filthy. Took out his hose and cleaned them. Then when done, did the heater PM and then โ€œsaid I just want to verify that ringing noise went away. Your house will cool much faster now!โ€ I really like what Princeton air offers, quality and care, diagnose and fix. Not rushing to get to the next job. Theyโ€™re so good I got the year round service plan.

Update may 2025&2026
Maurice is fantastic.
Prompt and knowledgeable. Great technician.
There was an urgent need for a mold problem to be handled in a bathroom. They quickly identified the problem, tested the seriousness, and took care of it – in a very timely fashion. They communicated with me all along the way so I could fully comprehend what was going on. All the people were very knowledgeable, pleasant and accommodating. My experience with them was excellent, and I would highly recommend them.
Eric M. was prompt, professional, courteous and quite helpful. I become a better consumer when I understand the problem & possible solutions. Eric was willing to answer my questions and made me feel secure that he would follow up to help fix our problem.

His demeanor was pleasant, he was professional and seemed to be quite knowledge!
Great service. Domenic was so helpful and explained everything done.
Jermaine Richmond was very knowledgeable and explained my plumbing issue throughly. Thank you.

Maurice Gaines who cleaned and serviced my air conditioner was fantastic! He was fast, respectful and very fast with the repairs.

He made me feel like I was getting the full respect and honesty I so needed for something so important and really appreciated the time he took to explain every and answer all my millions of questions. Also Princeton Air communications were fast and accurate , leaving no question unanswered as to timing and confirmation of appointment. Iโ€™m so happy with their staff and with Maurice- heโ€™s a gem!
Thank you!
The young man who came out to fulfill our annual service contract was extremely professional and was very thorough. Although he told us we needed a new ac unit I felt confident that he knew what he was talking about and took the right amount of time in order to make his recommendation. I want him back every year. Unfortunately I forgot his name because Iโ€™m old.

He then had Ricky call us with replacement ac unit recommendations. He was just as professional. He then took the time to visit our condo, take measurements himself and then made recommendations on what size unit to purchase. I really feel he saved us money. He was amazing.

We then were contacted by a gentleman named Steve who was a manager in the service and installation department. Itโ€™s hard to believe but he was just as good as the first two representatives and was an absolute pleasure to work with. He was a true professional and a real asset to your organization. I will always use your company if I can work with this team. Keep up the great work. Thanks for allowing me to spend $8,000.its hard to believe I didnโ€™t even get other quotes because I was so happy with your team.

Recently Princeton Air did a routine maintenance check on our HVAC UNIT. The technician was Dominic McGinley. I must say Mr. McGinley was outstanding. After performing the maintenance and evaluation, he sat down with us and explained his findings in precise detail. He has also taken pictures of everything he found. Dominic was a pleasure with whom to interact. He was professional, friendly, and extremely knowledgeable. He explained everything in terms that we could definitely understand. He is one of the finest technicians that has ever performed preventative maintenance on our equipment. In my estimation he has all of attributes of a first rate Service Technician. Hopefully Princeton Air just what a valuable asset he is for the company. I certainly hope to interact with him many times in the future.
We recently used Princeton Air to install a new heater. They gave us lots of options, explained each one thoroughly, they arrived promptly on installation day and did a great job. The price was the lowest of three companies I contacted for estimates. Five stars!
Always professional and informative.
We just had our A/C serviced by tech Dominic McGinley who performed a thorough spring maintenance. Dominic was very friendly and courteous. He responded in detail to all my questions spending sufficient time with me.
We had valve and service line repairs from Germaine and Bradley, as well as a toilet replacement. They were great!
Julian found an issue with the ac and resolved it. Explained what the component does that needed replacement.

Benefits of a Whole-Home Generator

A properly sized standby generator changes what a power outage means for your household.

Here’s what homeowners gain when they make the investment.

Nor’easters in Morristown, summer thunderstorms in Edison, ice events in Basking Ridge, hurricane remnants across the state: the grid in this region gets tested regularly. A standby generator takes the outage out of the equation. The lights stay on, the furnace keeps running, and life inside the house continues while the neighborhood waits for the power to come back. Most households that install a generator after a bad outage say they wish they’d done it years earlier. The first storm after the install is usually the moment the investment becomes obvious.

CPAP machines, home oxygen, refrigerated medications, and medical equipment with battery backups that only last a few hours all turn a power outage into a serious situation. For New Jersey households that have been through a multi-day outage after a hurricane remnant or a major winter storm, the stakes of losing power with medical equipment in use are not theoretical. A standby generator removes that risk entirely. The equipment keeps running, the household stays safe, and no one is counting down the battery life on a device that matters.

Finished basements across much of New Jersey rely on sump pumps to stay dry, especially during the spring rain and summer thunderstorm seasons that saturate ground across Somerset, Morris, and Middlesex Counties. When the power goes out during a heavy storm, which is exactly when the sump pump is working hardest, the basement floods. A standby generator keeps the sump pump running through the outage that would otherwise cause the flood. For homes with finished basements or valuable storage below grade, this alone is often reason enough to install.

Home offices, client work, and household income increasingly depend on uninterrupted power and internet. New Jersey’s working population has shifted meaningfully toward remote and hybrid work, and an outage that takes down the home office can cost a full day of billable time or a missed client meeting. A generator that keeps the router, modem, and work equipment online turns an outage into an inconvenience rather than a lost day. For households where one or more adults work from home full-time, the generator pays for itself in productive days across its life.

A whole-home standby generator is one of the home improvements that pays back in both daily comfort and resale value. Buyers in New Jersey increasingly see backup power as a feature worth paying for, especially in neighborhoods with a history of outages and in homes with finished basements, home offices, or aging residents. The return isn’t just the storm weeks. It’s the peace of knowing your home is prepared, and the buyer interest when it’s eventually time to move on.

Why New Jersey Homeowners Choose Princeton Air for Generator Installation

A generator is an investment that either works perfectly when it’s needed or feels like money wasted.

The installation is where that outcome is decided.

Every generator installation is completed by a licensed electrician. The transfer switch, the panel tie-in, and the code compliance are all the responsibility of someone qualified and accountable.

Generator sizing is the most important decision in the project, and we size against real outage patterns in this region, not generic assumptions. An outage here often means losing power for two or three days during a storm that also knocks out roads, which changes what a household needs the generator to cover.

Most standby generators in New Jersey run on natural gas from PSE&G, Elizabethtown Gas, or New Jersey Natural Gas, and some homes run on propane where utility service doesn’t reach. Our licensed team coordinates the electrical and fuel sides of the project so you’re not managing two contractors.

Generator installations require permits and inspections across New Jersey municipalities, and the requirements vary by town. We pull the permits, coordinate with the local inspector, and make sure the job passes before we close out the project.

From Wayne and Parsippany-Troy Hills to Freehold Township and Marlboro, we’ve installed generators across the state. Coastal communities that see the worst of tropical systems, inland neighborhoods hit by summer thunderstorm lines, and hill towns that lose power to ice all present different challenges. That range shapes every install decision.

We’re authorized on the major residential generator brands, which means warranty support stays intact and factory-trained service is available for the life of the unit. That matters when a generator lives 15 to 20 years and needs service from the same team that installed it.

The generator you install this year is the one that runs when the lights go out three winters from now. We stand behind the install, and we’re the team that services it through every year that follows.

Complete Home Services For Your Home

A generator installation often connects to other electrical work worth handling in the same visit.

A standby generator is the most important piece of a well-planned residential electrical system. The panel it ties into and the electronics it protects deserve the same attention.

When your existing generator needs diagnostic work or a repair, our team handles it with the same care we bring to installation. Catching a small issue early keeps it small.

Annual service is how a generator hits its rated efficiency and lifespan. Routine attention turns a system that might have lasted 10 years into one that lasts 15.

A whole-home surge protector at the panel protects every device in the house from voltage spikes, whether they come from the grid or from lightning. One of the cheapest protections for the most expensive electronics.

Older electrical panels weren’t designed for the draw of a modern household. A panel upgrade prepares the home for everything you want to plug in now and over the next 30 years.



Schedule Your Generator Consultation

A properly installed standby generator keeps the house running through whatever the weather brings.

If you’ve been through one too many outages, rely on equipment that can’t afford to go dark, or simply want the reassurance of backup power, our licensed electricians will walk the home, lay out the right system, and handle the full installation. Call Princeton Air today to schedule your consultation.

Generator Installation FAQs

What size generator do I need?

Generator sizing depends on which circuits and appliances you want to keep running during an outage. Essential-load generators cover a few critical items like the furnace, refrigerator, sump pump, and a few outlets, and are smaller and less expensive. Whole-home generators cover everything the grid would, including central air for New Jersey summers. We calculate the right size based on your actual needs.

Does a standby generator run on gas or propane?

Most residential standby generators in New Jersey run on natural gas from PSE&G, Elizabethtown Gas, or New Jersey Natural Gas. Propane is the answer in homes without utility gas service, which is common in some rural and hill communities across the state. Either fuel works reliably when installed correctly.

Will the generator start automatically when the power goes out?

Yes. A standby generator includes an automatic transfer switch that detects when utility power drops, starts the generator, transfers the home’s load to the generator, and then reverses the process when utility power returns. The whole sequence happens automatically, typically within 10 to 30 seconds of the outage. For New Jersey storms that cut power in the middle of the night, this matters.

How often does a generator need to be serviced?

Annual service is the standard, and some high-use units need twice-yearly attention. Oil changes, battery checks, transfer switch verification, and load testing all belong on the annual visit. Our Home Comfort Club members can schedule generator maintenance alongside their regular service visits.

How long does a generator installation take?

Most standby generator installations are completed in one to two days of on-site work. Permits, gas line coordination, and inspection scheduling can extend the overall project timeline to a couple of weeks depending on your municipality’s turnaround. You’ll have a clear schedule before any work begins.
