Common questions
Generator FAQs
How much does a whole-home generator cost on Long Island?
Whole-home standby generator costs vary based on the size of your home and the generator's capacity. Most residential installations range from $5,000 to $15,000 including installation. We provide free, no-obligation estimates.
How long does generator installation take?
Most whole-home generator installations take one to two days. This includes setting the generator pad, connecting to your gas line, and wiring the automatic transfer switch. Permits are typically required and we handle the process.
What size generator do I need for my Long Island home?
The right generator size depends on your home's square footage and what you want to power. A 20kW generator typically covers most Long Island homes. We'll assess your home and recommend the right capacity.
Do whole-home generators run on natural gas?
Yes. Standby generators connect to your home's natural gas or propane supply and start automatically within seconds of a power outage. No refueling needed — they run as long as the gas supply is available.
Do you service existing generators on Long Island?
Yes. We service and repair Generac, Kohler, Briggs & Stratton, and other standby generator brands. Annual generator maintenance is important to ensure it starts reliably when you need it most.
