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.

22 kW Standby Generator Installation in Ocean, NJ | Generac Generator

George from Ocean, NJ has been a Green Sun Energy Services client since September of 2021. The generator was commissioned in March of 2022: a Generac Guardian rated 19.5 kW on natural gas, on a 200-amp service-entrance switch with two smart management modules. The load calculation asked for 15 kW across the 2,688 square foot house, so there is a wide margin over the requirement. The siting is the notable part: a thirty-inch retaining wall was built before installation, filled with soil and pea gravel, to raise the pad and give the machine the ground clearance it needed – the

Standby Generator Service in Tinton Falls, NJ | Client Since November 2023

Chuck from Tinton Falls, NJ has been a Green Sun Energy Services client since November of 2023. The generator was installed by another company and commissioned in January of 2021, and the servicing came to us nearly three years later, starting with the two-year service that December. Cellular monitoring was set up at the same time, and the machine has been seen every year since – November of 2024 and November of 2025. The monitoring proved its worth in 2025, when it showed the generator had dropped offline and the household could be told rather than left to find out

Standby Generator Service in Lincroft, NJ | Servicing and Monitoring a Generator We Did Not Install

Kerry from Lincroft, NJ has been a Green Sun Energy Services client since July of 2026. The generator was installed by another company and commissioned in March of 2023, and the servicing came to us three years later. The first visit was the three-year service, completed in July of 2026, and cellular monitoring was set up within the fortnight. Fitting the monitoring at the same time as the first service is the sensible order: the visit establishes what condition the machine is actually in, and the monitoring keeps that picture current instead of letting it go stale until the next

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

Geoff from Port Monmouth, NJ has been a Green Sun Energy Services client since August of 2019. The generator was commissioned that December: a 16 kW Generac Guardian on natural gas, on a 200-amp whole-house transfer switch, sized against a 13 kW calculation for the 2,700 square foot house. Port Monmouth sits on the bay behind a hurricane barrier, in the stretch of Monmouth County that has been rebuilt once already after a storm surge – which puts backup power in a different light here than it would be a few miles inland. The generator is on annual maintenance with

17 kW Standby Generator Installation in Monroe Township, NJ | Whole-House Backup

Thomas from Monroe Township, NJ has been a Green Sun Energy Services client since January of 2022. The generator was commissioned that July: a Generac Guardian rated 17 kW on natural gas, on a 150-amp service-entrance switch with a smart management module and surge protection. The load calculation asked for 15 kW across the 1,886 square foot house, where an electric dryer and a separate freezer do more to set the number than the floor area does. An electric dryer alone draws roughly five times what a gas one does, which is why two houses of the same size can

18 kW Standby Generator Service in Hazlet, NJ | Generac Generator

Glenn from Hazlet, NJ has been a Green Sun Energy Services client since August of 2024. The generator was installed by another company and commissioned in August of 2023, and the servicing came to us a year later – early enough that the first-year service was the first visit rather than a catch-up. Cellular monitoring was set up within a fortnight, and the two-year service followed in September of 2025. Monitoring is the part that changes the character of the arrangement: a standby generator runs a weekly self-test that nobody watches, and a machine reporting its own results is the

Standby Generator Service in Green Brook, NJ | Servicing for a Business

CK Control Temp in Green Brook, NJ has been a Green Sun Energy Services client since October of 2024. The generator was installed by another company and commissioned in September of 2022, and the servicing moved to us two years later. The two-year service was completed in November of 2024, and the three-year service in January of 2026. For a commercial building the calculation behind backup power is different from a home: an outage does not mean discomfort, it means a business that cannot operate, and every hour of it is measurable. That is what the annual service is protecting

13 kW Standby Generator Installation in Elberon, NJ | Whole-House Backup

Nancy from Elberon, NJ has been a Green Sun Energy Services client since October of 2020. The generator was commissioned in May of 2021: a 13 kW Generac Guardian on natural gas, on a 200-amp whole-house transfer switch with a smart management module. The load calculation asked for 14 kW across the 2,500 square foot house, and the management module is what closes that gap – rather than fitting a larger machine, it holds back the heaviest draw for a moment when several things start at once, so the whole house stays covered. The garage had to be cleared before

Standby Generator Service in Lincroft, NJ | Servicing Taken Over

Li from Lincroft, NJ has been a Green Sun Energy Services client since August of 2024. The generator was installed by another company and commissioned in April of 2016, and the servicing moved to us eight years later. The first visit was the eight-year service in August of 2024, followed by the nine-year service in August of 2025. By that point in a machine’s life the parts that fail are rarely the dramatic ones – it is the battery, the plugs and the oil that decide whether it starts, and all three are consumables that quietly pass their date whether

24 kW Standby Generator Installation in Colts Neck, NJ | Generac Generator

Justin from Colts Neck, NJ has been a Green Sun Energy Services client since September of 2021. The generator was commissioned in February of 2022: a Generac Guardian rated 21 kW on natural gas, on a 200-amp service-entrance switch with two smart management modules. The load calculation asked for 20 kW across 4,100 square feet, and the list is why – a well pump, two sump pumps, two refrigerators, an electric dryer, a washer and a dishwasher. A well and sumps together is the combination that turns backup power from a comfort into a necessity: without it the house has

Standby Generator Service in Middletown, NJ | An Early Takeover of a New Generator

Anthony from Middletown, NJ has been a Green Sun Energy Services client since May of 2025. The generator was installed by another company and commissioned in April of 2024, and the servicing came to us barely a year later – before its first scheduled service had even fallen due. We ran the first-year service that May and the two-year service in April of 2026. Picking a machine up this early is the version of a takeover with no archaeology in it: nothing has been missed yet, no interval has been skipped, and the record from here is continuous. An annual

Standby Generator Service in Holmdel, NJ | Client Since 2022

Anthony from Holmdel, NJ has been a Green Sun Energy Services client since December of 2022. The generator was installed by another company and commissioned in January of 2021, and the servicing came to us two years later – early enough that the machine was still close to new. Cellular monitoring was set up in the same week, and an extended warranty was added in 2024. It has been seen every year since: December of 2022, January of 2024, December of 2024 and November of 2025, working up from the first-year service to the four-year, 600-hour one. Taking a machine
