Standby Generator Service in Holmdel, NJ by Green Sun Energy Services.
Richard from Holmdel, NJ has been a Green Sun Energy Services client since May of 2019. The 20 kW standby generator at the house was installed by another company in September of 2018 — barely eight months old when Richard moved its servicing to us and took an extended parts-and-labor warranty on it. Every interval since has been done in sequence, the one-year check through to the seven-year, completed in September of 2025 with 120.1 hours on the meter and the fuel plenum clear of rust. There has also been one repair carried out under the manufacturer’s warranty. Picking up a machine while it is still nearly new is the easy version of this work: nothing to undo, and a full service history from the first year onward.

Standby generator questions from Holmdel homeowners
Will a 20 kW generator run an entire Holmdel house?
For many homes, yes, but that does not mean every load can run at the same moment. Houses with two central air conditioners, electric heat, EV charging, pool equipment or electric cooking may need load management or a larger machine. The answer comes from a load calculation rather than from the phrase whole house.
How quickly does it take over?
The automatic start sequence normally begins within seconds of the controller deciding that utility power has failed or fallen outside acceptable limits. There is a deliberate short delay so that a momentary flicker does not trigger a full start and transfer. Exact timing depends on the controller, the transfer switch and the configuration.
Does the generator need its own gas shutoff?
The fuel installation has to include the shutoff arrangements required by the adopted fuel-gas code and by the installation instructions. The valve must be positioned where it is accessible, both for servicing and for isolating the machine in an emergency.
