Generac powers more American homes than any other standby brand — and Vaccarella Electrical Services is your authorized installer across Northern New Jersey. Automatic, whole-home backup power the moment the grid fails.
Why Generac
Reliable, Automatic Backup Power — Built for the Whole Home
Generac home standby generators live quietly outside your home and turn on automatically within seconds of a power outage — whether you're home or away. Powered by natural gas or propane and built around Generac's durable G-Force engine, a Generac unit can run your lights, HVAC, refrigerator, well pump, and medical equipment through storms, grid failures, and everything in between.
As a licensed New Jersey electrical contractor with 15+ years of installation experience, Vaccarella sizes, permits, installs, and services Generac generators to code — so your backup power is ready when you need it most.

Generac FAQs
Generac Generator Questions, Answered
A typical Generac air-cooled home standby generator (14–24kW) installed by Vaccarella Electrical Services generally runs from about $7,000 to $12,000 fully installed, depending on size, fuel type, distance from the gas meter/electric panel, and any electrical or plumbing upgrades needed. We provide free, no-obligation quotes with transparent, itemized pricing.
Sizing depends on what you want to back up. A 14–16kW unit can cover essential circuits, while a 22–24kW unit can run most or all of a whole home including central AC. During your free consultation we calculate your starting and running loads to recommend the right kW size.
Generac home standby generators run on either natural gas or propane (LP). If your home has a natural gas supply, we connect directly to it; otherwise we connect to a propane tank. Either fuel allows continuous, automatic operation during an outage.
As long as fuel supply is maintained, a Generac standby generator can run for days or even weeks. With natural gas, run time is effectively unlimited. With propane, run time depends on tank size — we help you size the tank appropriately.
Yes. Vaccarella Electrical Services pulls all required town permits and coordinates the electrical and any required inspections for you, so your Generac installation is fully code-compliant and worry-free.
Generac recommends maintenance every 200 hours of run time or once yearly, whichever comes first — including oil, filter, spark plug, and battery checks. We offer ongoing service so your unit is always ready.
