What does a home standby generator do?
It is a permanent generator installed outside the house, running on natural gas or propane. When the utility power fails, it starts on its own and powers your circuits through an automatic transfer switch, then shuts down when power returns.
What does a whole-house generator cost?
Fixr's national figures run from $10,000 to $20,000 installed, averaging about $15,000. HomeGuide puts a standard standby setup at roughly $6,000 to $11,000. Size, fuel and site work make the difference.
Who does the installation?
A local electrician or generator installer serving your town. They give you a quote, file permits and handle the work.
How big a generator do I need?
It depends on which appliances and circuits you want running. An installer sizes it with a load calculation rather than going by square footage.
Should I choose natural gas or propane?
Natural gas is simplest where it is available and the meter is big enough. Propane works anywhere but needs a tank on the property and deliveries.
Is a permit required?
Usually yes. Generator, transfer switch and panel work typically need permits and inspections, and your installer should arrange them.
What is a transfer switch?
It is the device that moves your home between utility power and generator power, and it keeps generator power from flowing back onto the utility lines.
Can I plug a portable generator into an outlet in my house?
No. That backfeeds power into the wiring and can reach utility lines, putting line workers at risk. Use a transfer switch or interlock installed by a licensed electrician.
Where can I safely run a portable generator?
Only outdoors, well away from doors, windows and vents. Never run it in a home, basement or garage, because of carbon monoxide.
How often should a standby generator be serviced?
Usually once a year, plus extra service after long outages. Fixr puts yearly maintenance at about $200 to $500.
Do I need a new panel for a generator or EV charger?
Not always. If your panel is old, full or small, an electrician may suggest an upgrade. They will tell you after an inspection.
Can a generator power a two-family house?
Yes, if it is sized and wired for both units, often with a transfer switch for each panel. It can also be set up for one unit only.
How can I check an electrician's license in Westchester?
In Westchester County, only a county-licensed electrician or someone they employ may do electrical work. Ask for the license number and a certificate of insurance. The county's Department of Consumer Protection can answer licensing questions.
