Philip from Holmdel, NJ has been a Green Sun Energy Services client since August of 2020. The 20 kW standby generator at the house was installed by another company in February of 2013, and Philip brought its servicing to us seven years later. Every interval from the six-year through to the ten-year was carried out, the last completed in July of 2023 with the fuel plenum inspected and clear of rust, along with a service call in between. The meter read 27.4 hours at that visit — a little over a day of running in a decade. A generator that has scarcely been called on is the one most likely to have quietly seized, gummed or gone flat, which is exactly why the annual visit matters more on a machine like this than on one that runs every month.

Standby generator questions from Holmdel homeowners
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.
Does a 200-amp service need a 200-amp transfer switch?
A transfer switch installed in the service path has to be rated appropriately for the service and the configuration. A 200-amp service commonly uses a 200-amp service-rated switch, but the actual design is confirmed by the electrician rather than assumed from the service size.
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.
