Grace and Kevin from Holmdel, NJ have been Green Sun Energy Services clients since April of 2022. The Generac 5887 at the house is rated 20 kW on propane and 18 kW on natural gas, runs on natural gas, and feeds a 90-amp transfer switch. It was installed in February of 2012 by another company. Green Sun has serviced it in June of 2024, May of 2025 and April of 2026. A machine that has been running since 2012 has outlived most of the appliances it backs up, and the annual visit is the whole reason that is possible.

Standby generator questions from Holmdel homeowners
What should a Holmdel homeowner look for in a generator installer?
A contractor who can design, permit, install, commission, maintain and repair the whole system rather than one who sells the machine. That means generator sizing and transfer equipment, disconnect and shutdown requirements, grounding and bonding, the manufacturer's own installation requirements, gas or propane capacity and pressure, the model-specific clearances, the municipal zoning setbacks, windows and vents and carbon-monoxide entry points, flood requirements where they apply, permits and inspections, utility coordination, load management, commissioning, warranty registration, monitoring and long-term service. The lowest proposal is not necessarily the lowest cost over the life of the system.
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.
Why does cold weather matter when sizing a propane tank?
Because propane's ability to vaporise falls as the outdoor temperature drops and as the liquid level in the tank falls. A supply that looks adequate in mild weather can struggle to support a large generator through a long winter outage if storage and vaporisation capacity were not designed for it.
