Thanh from Middletown, NJ has been a Green Sun Energy Services client since June of 2013, and we completed the Generac standby generator installation that September. The generator monitors the incoming power and takes over automatically when it drops, so the household never has to manage an outage — the heat stays on, the refrigerator keeps running and the sump pump keeps working. More than a decade on, scheduled maintenance under a Green Sun service plan keeps it starting reliably. Homeowners across Monmouth County rely on Green Sun Energy Services for standby power that holds up over the long term.

Green Sun Energy Services replied
Thank you, Thanh. Doing its job when needed is the only review a standby generator can really get. The machine at your home in Middletown was installed by our own crews and has been looked after since, and no complaints is a verdict we are happy to take. Thank you for choosing Green Sun Energy Services.

Standby generator questions from Middletown homeowners
Will an 11 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.
Can we build an enclosure around the generator?
A secondary enclosure should not be added unless the finished installation still complies with the manufacturer's requirements. Restricting the machine can reduce cooling airflow, trap heat, recirculate exhaust, block service access and create unsafe carbon-monoxide conditions. The factory enclosure is already engineered as part of the generator.
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.
