Stephen from Princeton, NJ has been a Green Sun Energy Services client since December of 2021. The generator was installed by another company and activated in April of 2020, and the servicing came to us the following year. It has been on a maintenance visit every year since – December of 2021, November of 2022, November of 2023, October of 2024 and October of 2025 – each one working through the service interval the machine had reached, from the first-year check to the five-year, 800-hour visit. In April of 2022 a starter failed; we handled the claim under the manufacturer warranty, replaced it and tested the unit back to a clean start.

Standby generator questions from Princeton homeowners
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.
Can a generator be raised on a platform?
Yes. Manufacturer guidance specifically covers installations on platforms and other supporting structures, and directs them to the applicable fire-safety standard, including a noncombustible surface extending beyond the generator for the configuration addressed. Flood and structural requirements have to be satisfied as well.
Can the existing natural-gas service in a Princeton 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.
