Green Sun Energy Services took over the servicing of a Generac standby generator at a home in Middletown, a client since July of 2026. The machine was installed by another company back in October of 2014 and had been running quietly ever since. The first visit under the new arrangement was completed in August of 2026, and it went in at the ten-year service interval rather than the hours-based one, because after twelve years the generator had recorded only 103.8 running hours. That is a telling number. A standby generator that has barely run is not a generator that needs nothing — seals dry out, fuel and oil age, batteries lose their charge, and none of it announces itself until the power goes off and the machine is asked to work. The service covers the annual visit: spark plug and air filter, oil and filter, battery inspection, load testing and diagnostics, firmware updates and a full performance check. An older unit that has been left alone is exactly the kind we would rather see on a schedule.

Standby generator questions from Middletown homeowners
Will a 22 kW generator run an entire Middletown 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.
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.
What is a sediment trap for?
It helps stop foreign material in the gas line from reaching the generator's fuel controls. Where the fuel-gas code and the system configuration call for one, it is fitted, and the maintenance schedule includes inspecting or cleaning it.
