David from Holmdel, NJ has been a Green Sun Energy Services client since August of 2026. The 22 kW Generac at the house was installed by another company in October of 2025, and the following year David moved its servicing to Green Sun. The first visit was a startup service – the full commissioning check a machine gets when it comes onto the plan – on a unit running natural gas behind a 100-amp transfer switch.

Standby generator questions from Holmdel homeowners
Can a standby generator be installed in Holmdel without natural gas?
Yes. Residential standby generators commonly run on liquid propane. A properly sized tank, regulator and piping system has to be designed to deliver adequate vapour flow and pressure for the machine.
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 sit next to the air-conditioning condenser?
Potentially, provided the installation preserves the clearances required by both machines. The generator's hot exhaust should not be directed at the condenser, and neither unit should obstruct the other's airflow or service access. In practice that often means about three feet or more of separation, but the manufacturers' actual requirements decide it.
