Whole Home Generator Installation
Protect every circuit in your home automatically — a whole home standby generator starts itself within seconds of detecting a power outage and runs until utility power is restored.
Whole Home Generator
A whole home standby generator is permanently installed outside your home and connected to your electrical panel and natural gas or propane supply. When a power outage occurs — at 2am, during a blizzard, or while you're away — the generator detects the loss of utility power and starts automatically within seconds. You may not even wake up.
Unlike portable generators, whole home units require no fuel storage, no manual startup, and no extension cords. They're designed to run for days or weeks if necessary, shutting down only when utility power is fully restored. They protect your entire home — HVAC, refrigerator, sump pump, medical equipment, security systems, and everything else.
As an authorized Generac dealer and installer, we handle every aspect of the project: site assessment, equipment selection, permit applications, propane or gas line coordination, electrical connection to your panel, and the required inspections. We're with you from the first call through the final sign-off.

Signs You May Need Whole Home Generator
Common indicators our Hudson Valley customers recognize before they call us.
You've Lost Power for Days at a Time
Hudson Valley ice storms and nor'easters can knock power out for 3–7 days. If you've lived through that once without backup power, you know exactly why a whole-home generator matters.
You Have a Sump Pump
The most dangerous time to lose power is during the heavy rain that often accompanies outages. A failed sump pump during a storm can mean thousands in flood damage.
You Have a Well Pump
No electricity means no water in homes on well systems. A whole-home generator keeps your water running throughout any outage.
Someone in Your Home Depends on Medical Equipment
CPAP machines, oxygen concentrators, refrigerated medications, and other medical devices require uninterrupted power. A standby generator removes any dependency on the grid.
You Travel or Are Away from Home Regularly
A whole-home generator protects your home automatically when you're away — pipes don't freeze, sump pumps keep running, and security systems stay active.
You Work from Home
A power outage means lost productivity, missed calls, and potential data loss. Standby power keeps your home office running without any interruption.
