Queens, NY Generator Installation

Whole home standby generators typically cost between $7,000 and $20,000 installed, depending on the generator size, brand, and complexity of the installation. Smaller units (10–16 kW) for essential circuits may start around $7,000–$12,000, while larger whole-home systems (20–22 kW and up) can range from $12,000–$20,000+. Generator Gators connects you with local installers who provide free, no-obligation quotes tailored to your home and needs.

A typical standby generator installation takes 1–3 days, depending on the complexity of the job, local permitting requirements, and utility coordination. Most installations can be completed in a single day once permits are approved and equipment is on-site. Your local installation partner will walk you through the expected timeline during your free quote.

Generator sizing depends on your home's square footage, the appliances and systems you want to power, and your electrical panel capacity. A 10–16 kW generator can typically power essential circuits (lights, refrigerator, sump pump, select outlets). A 20–22 kW generator can power most of a medium-sized home. Larger homes or homes with high-draw appliances like central AC may need a 24 kW+ unit. Our matched installers will assess your home and recommend the right size.

Yes — whole home standby generators are fully automatic. When utility power fails, the automatic transfer switch (ATS) detects the outage within seconds and starts the generator automatically. When utility power is restored, the generator shuts off and transfers power back — all without any action required from you. This is one of the biggest advantages over portable generators.

Most whole home standby generators run on natural gas or liquid propane (LP). Natural gas is preferred where available, as it connects directly to your home's gas line for an unlimited fuel supply. Propane is an excellent option if natural gas is unavailable. Some larger generators can also run on diesel. Your installation partner will recommend the best fuel option based on your home and location.

Yes, in most jurisdictions a permit is required for standby generator installation. This typically includes an electrical permit and sometimes a gas or mechanical permit. Your vetted local installer will handle permit applications and coordinate all required inspections. Always work with a licensed professional — this protects you and ensures your generator is safe and code-compliant.
