Standby Generator Installation and Standby Generator Service in Holmdel, New Jersey by Green Sun Energy Services.
Carol Ann from Holmdel, NJ has been a Green Sun Energy Services client since June of 2025. She signed at the end of June and the generator was commissioned in the middle of August, an 18 kW Generac on its own pad behind a 200-amp service-rated transfer switch with a whole-house surge protective device on the panel. The surge device is there for the moment the grid returns, which is when the damage usually happens. A Generac service contract covers it from here. Holmdel is in Monmouth County.

Standby generator questions from Holmdel homeowners
Can a standby generator run central air conditioning?
Yes, when it is sized for it. The design has to account for both the running demand and the starting surge of the air-conditioning equipment. Load-management equipment can be used where necessary so that demand does not all arrive at once.
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 new gas piping have to be pressure tested in Holmdel?
Yes. Gas piping subject to the adopted fuel-gas code must be inspected and tested before it is accepted. New Jersey adopts the 2024 International Fuel Gas Code, which governs the inspection, the test pressure and how long the test has to hold.
