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 does not cost a client the warranty they already have. An annual maintenance plan and a five-year extended parts-and-labor warranty now sit behind the machine.
Why Amanda chose Green Sun Energy Services

Standby generator questions from Summit homeowners
What is a service-entrance-rated transfer switch?
One that is listed for use as service equipment when installed in the appropriate configuration. These are commonly used for whole-house systems, where the transfer switch becomes part of the home's service arrangement rather than sitting downstream of it.
Can the existing natural-gas service in a Summit home supply a generator?
Often yes, but the gas system has to be evaluated first. The review covers the generator's BTU demand, meter capacity, available pressure, regulator capacity, pipe diameter and length, and every other gas appliance in the house -- furnace, boiler, water heater, range and fireplace among them.
Which fuel-gas code applies?
New Jersey currently adopts the 2024 International Fuel Gas Code as its Fuel Gas Subcode, which is what governs the piping, testing and shutoff arrangements on a natural-gas generator installation.
