How does a standby generator work?
It is installed permanently outside the house and runs on natural gas or propane. An automatic transfer switch starts it when the grid fails and hands the house back when power returns.
What does a standby generator cost?
HomeGuide splits a standard setup into roughly $3,000 to $6,000 for the equipment and $3,000 to $5,000 for the installation, and lists larger systems or long runs at $9,500 to $24,000. Steep lots, older panels and gas meter upgrades can push a Dobbs Ferry job higher. A written quote after a site visit is the real number.
Who does the installation?
A local electrician or generator installer who serves your town. They visit, quote, pull permits and install the system.
How do I know what size I need?
From a load calculation. The installer lists the heating, cooling, appliances and pumps you want running and sizes the generator to match.
Gas or propane?
Natural gas is the simplest where service is available and the meter can handle it. Propane works anywhere but needs a tank on the property and deliveries.
Can a generator go on a steep lot?
Usually yes. The installer finds a spot that meets clearance and setback rules, sometimes with a built-up level base, which can add cost.
Will I need a permit?
Almost always. Generator, transfer switch and panel work normally need permits and inspections, and the installer should arrange them.
What is backfeeding?
Backfeeding is sending generator power into a home's wiring without a transfer switch or interlock. It can push power onto the utility lines and injure line workers, so a generator should only connect through equipment installed by a licensed electrician.
Where should a portable generator run?
Outdoors only, far from doors, windows and vents. Never in a house, basement, garage or under a porch roof, because of carbon monoxide.
How often does a generator need maintenance?
Plan on a yearly visit, and an extra one after any outage where the unit ran for days. Fixr's national range for yearly maintenance is about $200 to $500.
Does an older house need a panel upgrade for a generator?
Sometimes. If the panel is old, full or small, an electrician may suggest an upgrade first. They will tell you after looking at it.
Can my generator charge an electric car?
Only if it is sized and set up for that. Many owners keep the charger off the backup circuits or let load management pause it.
How do I check an electrician in Westchester?
Ask to see the electrician's Westchester County license, since the county requires electrical work to be done by a licensed electrician or someone on their payroll. Ask for proof of insurance as well. The county Department of Consumer Protection can answer questions about a license.
