Standby Generator Installation and Standby Generator Service in Morganville, NJ

“We purchased a generator last October and it was installed by Green Sun Energy Services. There were a few delays beyond their control (snow, town permits, technical problem with the actual generator), but I was so pleased with the professionalism of everyone I dealt with Glen, Karen, Jennifer, Chris and all the technicians who worked to…”

Jeannie · Morganville, NJ · 2026

Green Sun Energy Services replied

Thank you, Jeannie. Snow, township permits and a fault in the machine itself is an unlucky run, and none of it is a reason to go quiet. The 17 kW standby at your home in Morganville uses load management to work inside a 100-amp service, which is a neater answer than upgrading the service. Glad the team made the wait bearable.

“Mike serviced and installed a new battery for my generator.He did a great job and was very helpful with all my questions.Thank You.”

Thomas · Middletown, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Thomas, and Mike will be pleased. A battery is the single most common reason a standby generator fails to start, so replacing one during a service visit is routine work that heads off a bad surprise later. The 16 kW machine at your home in Middletown is in good order, and questions are always welcome.

“Could not be more happy with the service s from Green Sun. Highly recommend.”

Middletown, NJ · 2026

Reviewed us onAngiFacebookGoogle

Green Sun Energy Services replied

Thank you. Standby power at your home in Middletown since 2013 is a long stretch, and the services in between are the reason the machine is still worth having. We are grateful for the recommendation and for a relationship that has run this long.

Softwash Service, Standby Generator Installation and Standby Generator Service in Farmingdale, NJ

“Our house, patio, walkways and driveway was recently soft washed. Very pleased with the result.”

Farmingdale, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Richard. Soft washing a house, patio, walkways and driveway in Farmingdale is low-pressure work by design: the cleaning is done by the solution rather than by force, which is what keeps siding, mortar and plantings intact. Glad the result was worth waiting for a dry week.

Chris · Middletown, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Chris, and Mike will be pleased. Your Generac standby generator in Middletown was installed by our own crews and is serviced by them too, which is why a visit tends to be efficient: nobody has to work out how the system was put together first. Thank you for the review.

“Mike was awesome and serviced our generator in frigid temperatures!”

Greg · Middletown, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Greg, and Mike deserves that one. Generators get serviced in whatever weather the calendar hands us, and a cold morning in Middletown is when the machine is most worth proving. Better a hard test in February than an easy one in June and a surprise later.

Standby Generator Service in Holmdel, NJ

“A Pleasure”

Benjamin and Celeste · Holmdel, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Benjamin and Celeste. Short and generous, and we appreciate it. Your standby generator in Holmdel is looked after on an annual service plan, which means the machine is inspected, load-tested and tuned on a schedule rather than the first time you need it. That is the quiet part of backup power, and it is the part we like doing best.

Standby Generator Service in Highlands, NJ

“Mike was very polite, quick and efficient. He explained exactly what he would be doing.”

Dave · Highlands, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Dave, and Mike will appreciate that. Saying what is about to happen before it happens is a small thing that makes a service visit much easier to sit through. The generator at your home in Highlands is on an annual plan, so the same checks happen every year and nothing is skipped for time.

Standby Generator Service in Long Branch, NJ

“5-Star google review”

Suzanne · Long Branch, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Suzanne. The 11 kW Generac at your home in Long Branch has been with us since 2019 and serviced every year since, so it is ready rather than merely installed. A machine that size covers the essentials of a house comfortably, and keeping it on a schedule is what turns equipment into peace of mind.

“The young man (Mike) was very competent and nice. He informed me of everything he did during the service call. He spent quite a lot of time and I am very satisfied.”

Carolanne · Bridgewater, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Carolanne, and Mike will be pleased. Taking the time is the point: the generator at your home in Bridgewater has been serviced by us since 2019, and a visit that is rushed is a visit that finds nothing. Saying what was done as it was done is how the record stays useful to both of us.

“Mike came for a routine maintenance service and did an excellent job. He was very courteous and polite.”

Dominic · Farmingdale, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Dominic, and Mike will be glad to hear it. Routine is the right word for what an annual generator service should feel like from the homeowner's side: the 22 kW machine in Farmingdale gets the same checks every year, and courtesy on the doorstep is in the job description rather than a bonus.

“5-STAR GOOGLE REVIEW”

Paul · Middletown, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you for the rating. Your standby generator in Middletown is looked after on an annual maintenance plan: oil and filters, spark plug, battery, firmware and a full load test at every visit. It is unglamorous work, and it is the reason the machine starts on the night that matters.

Joseph · Shrewsbury, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you for the five stars. Your generator in Shrewsbury is on one of our plans that pairs the annual service with remote monitoring we watch ourselves, so if the machine reports a fault between visits we tend to know before you do. Quiet is the intended result, and we are glad that is what it has given you.

Green Sun Energy Services replied

Thank you, Sandra, and Mike will be glad to hear it. Annual generator service in Red Bank covers the plugs, filters, oil and battery, a full load test and a diagnostics check, and the part that is not on the list is explaining what was found. Courteous and thorough is exactly the pairing we ask for.

Tim · Belford, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Tim, and Mike will be glad it was painless. An annual tune-up on the generator in Belford is plugs, filters, oil, battery and a full load test, done in a morning and logged so that next year starts from a known position. Quick and easy is the intended experience.

Tim · Hazlet, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Tim. Being told exactly how it works is deliberate: a standby generator in Hazlet only earns its keep if the household knows what it will and will not do. Yours went in and has been serviced by us since 2017. Flawless is a generous word and we will try to keep deserving it.

David · Belford, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, David, and Mike will appreciate that. The standby generator at your home in Belford is serviced annually, which is less about fixing anything and more about proving the machine will run on the day the grid stops. Quick, thorough and no surprises is what a good service visit looks like.

“I contacted Green Sun after receiving several error messages and interruptions of service of my Generac generator, which Green Sun installed several years ago. As usual, they responded immediately, and service technician John was here exactly when scheduled. He explained what the possible problem might be and proceeded to fix the issue…”

Nadine · Middletown, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Nadine, and John will be glad to hear it. Error messages are the machine doing its job: a generator that reports a fault is one you can put right before you need it. The Generac at your home in Middletown was ours from the start, which is why a call about it gets an immediate answer rather than a diagnosis from scratch.

“Good company. Great Tech.”

Michael · Belford, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Thank you, Michael, and the technician will be glad to hear it. Your Generac standby generator in Belford was installed by our own gas and electrical crews and has been on an annual service plan since, so the people who put it in are the ones who keep it running. That continuity is deliberate, and it is what makes a service visit quick.

Standby Generator Service in Atlantic Highlands, NJ

“Mike at Green Sun did a fantastic job with my generator. We’ve trusted them for year to do maintenance on it and haven’t had a single issue. It starts right up whenever is needed. When Mike came this year to service it, he had great attention to detail, replacing/refreshing all necessary components. I hardly even noticed he was there…”

Alexander · Atlantic Highlands, NJ · 2026

Green Sun Energy Services replied

Thank you, Alexander, and Mike will be glad to hear it. Starting right up whenever it is needed is the only thing a standby generator has to do, and it does that because somebody looks at it every year. The machine at your home in Atlantic Highlands is also monitored remotely, so a fault between visits reaches us rather than waiting for the next one.

Doug · Middletown, NJ · 2026

Green Sun Energy Services replied

Thank you, Doug. Explaining it clearly is the part we care most about. The 22 kW Generac at your home in Middletown was sized from a survey of what the house actually runs rather than from a rule of thumb, and knowing why the number is what it is makes the whole thing easier to live with. Glad the machine has earned its place.

Green Sun Energy Services replied

Thank you, Anne. Soft washing a house on the island means salt air as well as the usual growth, and Ship Bottom exteriors take more of a beating than most. Low pressure and the right solution do the work, which is why the finish lasts rather than simply looking clean for a fortnight. Glad the crew did you proud.

Thank you for the five stars. Your generator in West Windsor is covered by one of our annual maintenance plans, so the spark plug, filters, oil, battery and load test are all handled on a schedule and the machine is checked long before an outage arrives.

Thank you, Mark. Supportive is a good word for what we try to be during an install.

Glad the experience matched the intention.

Thank you, Deborah, and Mike will be glad to hear it. Yours is a three-part house in Lawrence Township: a solar array, a standby generator and an EV charger, each doing something the others cannot.
