22 kW Generac standby generator in Holmdel, NJ

“John and Auston were a stellar team, their attention to detail was amazing. Thank you!”

Holmdel, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Desiree, thank you for taking the time to leave a review. John and Auston were glad to tackle the full exterior soft wash on your Holmdel home — over 10,000 square feet of stucco, columns, driveway, and pool deck is a serious day's work, and we're pleased the results showed. We look forward to continuing to take care of your property.

Solar Panel Installation in Middletown, NJ

“Considering solar? Why not have the pros from Green Sun Energy Services provide a free analysis? That's what I did. Made the decision easy for me and my wife and convinced us of the benefits! The whole process from conception through installation went perfectly!”

Gerald · Middletown, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Gerald, thank you for sharing this. Thirty-four Jinko panels pulling 14.62 kW is a serious system, and we're glad the process from that first analysis through the November installation on Tanglewood Road went the way it should. Enjoy the production.

18 kW Generac standby generator 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

Reviewed us onGoogle

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.

“Austin visited for the yearly maintenance on our generator. He was courteous, pleasant, and professional. He explained everything he did in detail. I appreciate that Green Sun keeps track of the maintenance schedule so I don't have to. Great service.”

Barry · Lambertville, NJ · 2026

Reviewed us onGoogle

Green Sun Energy Services replied

Barry, thank you for the kind words about Austin — glad to hear the visit went smoothly. You're right that we track the intervals so you don't have to, and we're happy to keep doing that. Your 16 kW unit is in good shape heading into fall, and we'll see you again as scheduled.

16 kW Generac standby generator in Middletown, NJ

“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.

10 kW Generac standby generator in Fair Haven, NJ

“As an engineer, I appreciate and recognize what it takes to plan and execute an excellent job, and thats what Green Sun Energy did for us with the installation, and now ongoing maintenance, of our stand-by generator.”

Ronald and Robin · Fair Haven, NJ · 2026

Reviewed us onBBB

Green Sun Energy Services replied

Thank you, Ronald. Coming from an engineer that means a good deal. Essential-circuits backup at your home in Fair Haven is a design decision rather than a compromise: the transfer switch carries the circuits that actually matter, which keeps the machine right-sized and the install clean. Planning it properly is where most of the work sits.

“Our annual service was done yesterday by John he was amazing and has been serving our generator for a few years now, the whole team is amazing!”

Annamaria · Red Bank, NJ · 2026

Reviewed us onYelp

Green Sun Energy Services replied

Thank you, Annamaria, and John will be glad to hear it. Sending the same technician back year after year is deliberate: the generator at your home in Red Bank has a history, and the person who knows it spots a change faster than a stranger would. Good to hear the whole team came through as well.

Since becoming Green Sun Energy Services clients back in January 2013, we truly appreciate the trust you’ve placed in our team over the years.

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.

“Mike was very efficient and the service went smoothly.”

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.

“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.

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.

“Generator service handled by Mike. Courteous.”

Sandra · Red Bank, NJ · 2026

Reviewed us onGoogle

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.

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.

Nadine · Middletown, NJ · 2026

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.

“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.

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.

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.

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.
