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.

14 kW Standby Generator Installation in Fair Haven, NJ | Backup and Two Sump Pumps

Adrianna and Richard from Fair Haven, NJ have been Green Sun Energy Services clients since February of 2021. The generator was commissioned that November: a 14 kW Generac Guardian on natural gas, outdoors beside the meter, with a 100-amp service-entrance switch and a smart management module. The load calculation asked for 14 kW across the 2,300 square foot house, and the two sump pumps are the reason that number matters more than the floor area does. A storm that takes the power out is usually the same storm filling the basement, and sump pumps are the one load where losing

Standby Generator Service in Summit, NJ | Servicing Taken Over

Amanda from Summit, NJ has been a Green Sun Energy Services client since April of 2025. The generator was installed by another company and commissioned in July of 2022, and the servicing moved to us not quite three years later. The first visit was the three-year service in April of 2025, followed by the four-year service in March of 2026 and a manufacturer warranty repair that July. Handling a warranty claim on a machine somebody else installed is worth saying plainly: the manufacturer’s cover follows the generator rather than the company that put it in, so switching who services it

Generator Service in Freehold, NJ | Client Since 2022

Tyler from Freehold, NJ has been a Green Sun Energy Services client since October of 2022. The generator was installed by another company and commissioned in May of 2013, and the servicing came to us nine years later. It has been seen every fall since – October of 2022, November of 2023, October of 2024 and October of 2025 – starting at the nine-year service and repeating the ten-year interval once the machine reached it. Booking the visit for fall rather than spring is deliberate: the machine gets checked and put right before the season most likely to call on

21 kW Standby Generator Installation in Manasquan, NJ | Whole-House Backup

Anthony from Manasquan, NJ has been a Green Sun Energy Services client since September of 2021. The generator was commissioned in July of 2022: a Generac Guardian rated 21 kW on natural gas, sited on the right side of the house, with a 200-amp service-entrance switch and two smart management modules. The load calculation asked for 20 kW across 3,800 square feet, and the list explains it – a double electric oven, two refrigerators, a separate freezer, a sump pump, a washer, a gas dryer and a dishwasher. Cold storage and a sump between them are what make a long

Standby Generator Service in Westfield, NJ | Six Generator Services

Scott from Westfield, NJ has been a Green Sun Energy Services client since September of 2020. The generator was installed by another company and commissioned in July of 2014, and the servicing came to us six years later. It has been seen every year since – September of 2020, September of 2021, October of 2022, November of 2023, October of 2024 and November of 2025 – from the six-year service through to the ten-year interval it now repeats. The battery was replaced in November of 2022, which is the most common reason a standby generator fails to start: the engine

16 kW Standby Generator Service in Aberdeen, NJ | Generac Generator

Frank from Aberdeen, NJ has been a Green Sun Energy Services client since December of 2021. The generator was installed by another company and commissioned in October of 2019, and the servicing came to us two years later. It has been seen every fall since – December of 2021, December of 2022, December of 2023, November of 2024 and November of 2025 – working straight up the intervals from the two-year service to the six-year, 1,000-hour one. An unbroken run like that is worth more than any single visit in it: the value of a service record is that it

Standby Generator Installation and Solar Panel Installation in Matawan, NJ | 6.65 kW Solar & 16 kW Generac

Ana in Matawan has been a Green Sun Energy Services client since October of 2019. She signed for the standby generator and the solar array on the same day, and the two were commissioned forty-eight hours apart that December. A 16 kW machine on 16 December: The machine is a Generac 16 kW, model 70371, rated 16 kW on natural gas and on propane alike, and this house runs on natural gas. It stands outdoors beside the meter behind a 200-amp service-rated transfer switch. The house is 2,550 square feet and its electrical calculation comes to 16,516 watts. A 4,000-watt

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

Donald from Perrineville, NJ has been a Green Sun Energy Services client since November of 2021. The generator was commissioned in June of 2022: a Generac Guardian rated 19.5 kW on natural gas, feeding a GenReady load center in the basement with two smart management modules. The load calculation asked for 18 kW across 2,600 square feet, and the well pump on the list is the item that changes the character of an outage out here – a house on a well has no water at all once the power stops, which puts backup in a different category from keeping

22 kW Standby Generator Installation in Oceanport, NJ | Whole-House Backup

Paul from Oceanport, NJ has been a Green Sun Energy Services client since February of 2022. The generator was commissioned that August: a Generac Guardian rated 19.5 kW on natural gas, outdoors beside the meter, with a 200-amp service-entrance switch, a smart management module and surge protection. The load calculation asked for 19 kW across the 2,125 square foot house, with a double electric oven, two refrigerators, a washer, a gas dryer and a dishwasher on the list. One detail decided the schedule rather than the equipment: the gas line feeding the house had to be sized to carry the

Generator Service in Middletown, NJ | Client Since August 2020

Noreen from Middletown, NJ has been a Green Sun Energy Services client since August of 2020. The generator was installed by another company and commissioned in August of 2013, and the servicing came to us seven years later. It has been seen every summer since – August of 2020, August of 2021, August of 2022, August of 2023, July of 2024, June of 2025 and June of 2026 – starting at the seven-year service and continuing at the ten-year interval once the machine reached it. That last point is the one worth making: the service schedule does not stop when

Standby Generator Service in Sea Girt, NJ | Four Generator Services

Steven from Sea Girt, NJ has been a Green Sun Energy Services client since March of 2022. The generator was installed by another company and commissioned in June of 2013, and the servicing came to us nearly nine years later. Its scheduled maintenance has been kept since – April of 2022, December of 2024, January of 2025 and January of 2026 – and two faults that arose in between were each put right on their own visit. Sea Girt is a block from the ocean, and salt carries further inland than most people assume, so on a machine that has

22 kW Standby Generator Installation in Toms River, NJ | With a GenReady Panel

Glenn from Toms River, NJ has been a Green Sun Energy Services client since October of 2021. The generator was commissioned in May of 2022: a Generac Guardian rated 19.5 kW on natural gas, feeding a GenReady load center in the basement with three smart management modules. A GenReady panel is a different approach from a transfer switch bolted next to the meter – the load center itself does the switching, which keeps the wiring tidier and puts the load management inside the panel where the circuits already are. The load calculation asked for 15 kW across 3,100 square feet,
