Standby Generator Installation in New York

If an outage means no well pump, no furnace and a spoiled freezer, a standby generator ends that. We size it to the circuits you rely on, wire the automatic transfer switch, and coordinate the gas connection and inspection.

Short answer

A standby generator installation in Orange County or the city typically runs about $7,000 to $15,000 installed, according to 2026 national cost guides, and includes the unit, an automatic transfer switch, a pad, a gas connection and permits. It starts itself within seconds of an outage, so nobody has to be home.

What the job involves

What a standby generator job includes

A standby unit sits outside on a pad, runs on natural gas or propane, and connects to the house through an automatic transfer switch. When utility power drops, the switch disconnects the utility, starts the generator and moves your circuits over; when power returns, it switches back and lets the engine cool down.

The electrical work is the transfer switch, the feed from the generator and any subpanel for essential circuits. The gas side is handled by a licensed gas fitter we coordinate with, because the unit's appetite can exceed what an existing meter supplies. If you already own a portable unit and only need a safe hookup, an interlock kit and inlet is the smaller project.

What moves the price

What moves the price of a standby generator

Published ranges are wide because these details vary so much.

  • Generator sizeAn essentials unit costs far less than one sized for central air.
  • Service conditionAn old or 60 amp service may need upgrading first.
  • FuelNatural gas needs meter capacity; propane needs a tank and delivery.
  • Distance and placementLonger runs to the panel and gas supply add material.
  • Transfer switch typeService-rated, load-managing switches cost more.

Common versions of this job

Three ways a standby system is set up

Whole-Home Standby Generator

A whole-home unit is sized to run everything, including central air, the range and the dryer, often with load management so the largest loads take turns. It suits homes where someone is home all the time, where medical equipment runs, or where the owner simply does not want to think about outages. The transfer switch replaces or sits beside the main service disconnect, so the work touches the service entrance and is coordinated with the utility where a meter pull is needed.

Planning range (national sources, 2026): $7,000 to $15,000 installed; transfer switch and electrical $1,500 to $3,500. Coastal-market pricing and building access change the figure; this is a planning band, never a quote.

Essential-Circuits Generator

An essential-circuits system backs up only what you choose: furnace or boiler, well pump, refrigerator, sump pump, a few lights and outlets. Those circuits move to a small subpanel fed through the transfer switch, which lets a smaller generator do the job. It is the common choice in Warwick-area houses on wells, where water and heat matter more than central air. Adding a circuit to the essentials list later is a small job, as long as the subpanel was sized with spare spaces.

Planning range (national sources, 2026): about $7,500 on average; sub-panel for the unit $500 to $2,000. Coastal-market pricing and building access change the figure; this is a planning band, never a quote.

Automatic Transfer Switch and Load Shedding

The transfer switch is what makes a standby unit hands-free. It watches utility voltage around the clock, starts the generator when that voltage drops or disappears, transfers once the engine is stable and transfers back when power returns. Load-shedding modules add a second layer: they hold off an air conditioner, an electric range or a water heater until the generator has spare capacity, which is how a mid-sized unit can carry a whole house without stalling or tripping its own breaker.

Included in the visit

What the installation includes

  • Load calculation and generator sizing
  • Placement at the manufacturer's clearances from openings
  • Pad set level for the unit
  • Automatic transfer switch and any essentials subpanel
  • Gas connection by a licensed fitter we coordinate
  • Permit, inspection and startup test
  • Walkthrough of the exercise schedule and maintenance
Local conditions

Houses that need it most

Orange County has plenty of houses built before 1960, and some still run on 60 amp service, which is the costliest starting point for any upgrade because the service usually has to be modernized before a transfer switch can go in. Around Warwick the requests tend to be practical: keep the well pump and the boiler running, and stop the lights flickering through every ice storm. We check the service first so the generator is not sized around a panel that is about to change.
