Drew from Lincroft, NJ has been a Green Sun Energy Services client since January of 2024. The 20 kW Generac had been installed by another company in June of 2013, so by the time the servicing came to us the machine was ten years old. It has been seen every year since – January of 2024, March of 2025 and February of 2026 – and it runs the whole house through a 90-amp transfer switch on natural gas. A generator that age stands or falls on what happens at the annual visit, which is the only time anyone sees it running under load.

Standby generator questions from Lincroft homeowners
Does new gas piping have to be pressure tested in Lincroft?
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.
Will the sump pump keep working if the power goes out?
It will if it is on the generator. This matters most in exactly the weather that causes outages: heavy rain and a power cut tend to arrive together, and a sump pump without power cannot keep a basement dry. A sump pump is one of the loads worth confirming during the survey rather than assuming.
Does a generator produce less on natural gas than on propane?
Some models do have a lower rated maximum output on natural gas than on propane -- a current 22 kW machine is rated 22 kW on LP and 21 kW on natural gas. Other models carry their own ratings, so the model-specific specification sheet is what settles it rather than a general rule.
