Generators on Long IslandWhole-home generator installation — the lights stay on.

It depends on your actual connected load, not your square footage. A typical Long Island home with one central AC system, gas heat, a refrigerator, and a sump pump is well served by 18–22 kW for whole-home coverage. Homes with two AC systems, a well pump, or a pool usually need 24 kW or more. We run a written load calculation before quoting.

The physical install is one to two days. Town and utility approvals ahead of it typically take one to three weeks, so plan on roughly three to five weeks from signed proposal to a commissioned system.

If natural gas is already at the house, use it — unlimited runtime and no refueling during a multi-day outage. If you're not on gas, propane works just as well, but you'll need a tank sized for the runtime you want; a 500-gallon tank typically carries a 22 kW unit for several days of realistic cycling.

Modern air-cooled units run about 60–67 dB at 23 feet — roughly a window air conditioner. The weekly self-test lasts about five minutes and can be scheduled for a time that suits you. Placement matters for noise, and we account for it and for the code clearances from windows and doors.

Yes, with correct sizing. AC compressors draw a large startup surge, so we either size the generator for it or install a load-management module that briefly sheds a lower-priority load when the compressor kicks on. Both approaches are common; we'll tell you which is cheaper for your house.

Once a year, or every 150–200 running hours. Annual service runs $249–$389 and covers oil, filters, plugs, battery test, gas pressure, transfer switch check, and a full load test. Dead batteries cause more no-starts than any mechanical failure, which is exactly what annual testing catches.

Yes. We service and repair existing Generac, Kohler, Cummins, and Briggs & Stratton standby systems regardless of who installed them, including transfer switch faults and no-start diagnostics.

For homes with a sump pump, a well, medical equipment, or anyone working from home, usually yes — a single multi-day outage can cost more in spoiled food, basement water damage, and hotel nights than a year of the financed payment. For a home with none of those and a gas stove, an essential-circuit system at the lower end of the range is often the smarter buy.

One year on our labor plus the manufacturer's parts warranty, which runs five years on most Generac and Kohler air-cooled home standby units. We register the manufacturer warranty at commissioning.
