A generator sits quietly for a year and then has to work on the one night it matters. That means the battery, the oil, the weekly test cycle and the transfer switch, all checked before the storm rather than during it. These are New Jersey homes we look after on a maintenance plan, and plenty of the generators on this list were installed by somebody else. Each one names the equipment on site and the town, so what you are reading is work we actually did rather than a list of what a plan covers.

939 completed generator service projects across 142 New Jersey towns, including 165 with a review written by the customer.

Standby Generator Service in Belford, NJ | Servicing Taken Over

Robert from Belford, NJ has been a Green Sun Energy Services client since March of 2026. The generator was installed by another company and commissioned in August of 2017, and the servicing came to us nearly nine years later. The first visit was the nine-year service in March of 2026, and a manufacturer warranty repair followed in July. Belford sits on the bay side of the peninsula, where salt in the air works on everything left outdoors, so an enclosure that has been through nine summers there deserves a closer look than the interval alone would suggest. The generator is

Generator Service in Keansburg, NJ | Client Since 2020

The household at 106 Forest Ave in Keansburg, NJ has been a Green Sun Energy Services client since June of 2020. The generator was installed by another company and commissioned in December of 2014, and the servicing came to us five and a half years later. It was seen each spring after that – June of 2020, June of 2021, May of 2022 and May of 2023 – working through the intervals from the five-year service to the eight-year, 1,400-hour one, with two repair visits handled that fall of 2020. Keansburg sits right on the bay, and salt air is

Standby Generator Service in New Egypt, NJ | Two Seasons of Generator Service, Client Since 2020

Julio from New Egypt, NJ has been a Green Sun Energy Services client since July of 2020. The generator was installed by another company and commissioned in January of 2015, and the servicing came to us five years later. We ran the five-year service in August of 2020 and the six-year service in August of 2021. Both were timed for late summer, which is the sensible window in this part of Ocean County – far enough past the spring storms to have caught anything they caused, and comfortably ahead of the stretch from September onward when the machine is most

Standby Generator Service in Red Bank, NJ | First-Year Generator Service

Michael from Red Bank, NJ has been a Green Sun Energy Services client since November of 2019. The generator was installed by another company and commissioned in February of 2019, and we were called in later that year for its first-year service, completed in December of 2019. The first service is the one owners are most tempted to skip, on the reasoning that a machine less than a year old cannot need anything yet. It is the opposite: the first year is when the oil has picked up whatever the engine shed while breaking in, and changing it out on

Standby Generator Service in Rumson, NJ | Servicing Since 2019

Tom from Rumson, NJ has been a Green Sun Energy Services client since July of 2019. The generator was installed by another company and commissioned in February of 2016, and the servicing has been ours since – August of 2019, July of 2020, July of 2021, June of 2022, August of 2024 and July of 2025 – working up through the intervals from the three-year service to the nine-year, 1,600-hour one. Two repairs were handled under the manufacturer’s warranty along the way, in 2021 and 2022. A generator a decade into its life is past the point where faults announce

22 kW Standby Generator Installation in Columbus, NJ | Backup for a Well and Two Sumps

Frank from Columbus, NJ has been a Green Sun Energy Services client since April of 2021. The generator was commissioned that December: a Generac Guardian rated 19.5 kW on natural gas, outdoors beside the meter, with a 200-amp service disconnect and three load management modules. The load survey is worth reading on this one – 4,000 square feet with a well pump, two sump pumps, a double electric oven, two refrigerators, a washer, a gas dryer and a dishwasher. A well pump matters more than most items on that list, because when the power goes out a house on a

Standby Generator Service in Springfield, NJ | A Newer Generator Picked Up

Jason from Springfield, NJ has been a Green Sun Energy Services client since January of 2024. The generator was installed by another company and commissioned in May of 2023, so it was still close to new when the servicing came to us. We started with a startup inspection, the visit that establishes what a machine we did not install has actually got – hours, settings, how it was commissioned and whether anything was left unfinished – and then ran the first-year service in June of 2024. The two-year service followed in March of 2025 and the three-year, 400-hour in March

Standby Generator Service in Hightstown, NJ | Servicing for a Business

Anirdesh LLC in Hightstown, NJ has been a Green Sun Energy Services client since November of 2024. The standby generator was installed and commissioned by another company in April of 2020, and the servicing moved to us four years later. The first visit was the four-year service in November of 2024, followed by the five-year service in October of 2025. For a business the calculation behind a generator is different from a home: an outage does not just mean discomfort, it means doors closed, stock at risk and a day that cannot be made back, so the machine has to

16 kW Standby Generator Installation in Farmingdale, NJ | Whole-House Backup

Joseph from Farmingdale, NJ has been a Green Sun Energy Services client since May of 2020. The generator was commissioned that October: a 16 kW Generac Guardian on natural gas, with a 150-amp service-entrance transfer switch mounted inside the garage. The load calculation asked for 15 kW across the 2,269 square foot house, and the electric oven is a fair part of why – an oven pulls steadily and heavily for as long as it is on, which is easy to forget when listing what a house needs during an outage. A refrigerator, washer, gas dryer and dishwasher make up

Standby Generator Service in Monmouth Beach, NJ | Monitoring Added to an Older Generator

Kathy from Monmouth Beach, NJ has been a Green Sun Energy Services client since August of 2023. The generator was installed by another company and commissioned in February of 2013; the servicing came to us a decade later. The first job was fitting cellular monitoring so the machine could report for itself, which on a unit of that age is the single most useful thing that can be added – the failures that matter are the ones nobody sees, and a generator that only gets tested by an outage is a generator you find out about too late. It has

Standby Generator Service in Atlantic Highlands, NJ | Servicing Every Fall

Waleed from Atlantic Highlands, NJ has been a Green Sun Energy Services client since September of 2022. The generator was another company’s install, commissioned in January of 2020, and the servicing moved to us a little under three years later. It has been seen each fall since – October of 2022, November of 2023, October of 2024 and October of 2025 – working up through the intervals from the two-year service to the five-year, 800-hour one. Timing it for fall is deliberate on a house like this: the machine gets checked, run and put right before the season that actually
