Whole-home Generac standby generators, installed by a licensed NJ electrician. Automatic backup power that kicks in within seconds — for hurricanes, nor'easters, summer storms, and everything else the grid throws at New Jersey.
Between summer storms, nor'easters, hurricanes, ice events, and aging grid infrastructure, the average New Jersey homeowner deals with multiple outages per year — some lasting hours, some lasting days.
A whole-home Generac standby generator solves this once. It sits permanently outside your home, runs on natural gas or propane, and turns itself on within seconds when utility power drops — whether you're home or not.
Generac air-cooled and liquid-cooled standby generators — from essential-circuits backup to true whole-home power. We size based on your home's actual load.
Critical circuits — fridge, sump, a few lights, well pump. Great for smaller homes or backup minimums.
Whole-home backup for typical 2,000–2,800 sq ft NJ houses. AC, heat, kitchen, sump, well, all the basics.
Larger homes with multiple AC zones, big appliances, EV chargers. Top of the air-cooled lineup.
Large estates, mixed-use, or commercial properties. Heavy-duty liquid-cooled units for continuous heavy load.
A standby generator is a serious piece of electrical equipment tied directly to your home's main panel and gas line. Don't trust the install to a handyman or a referral-based subcontractor — you want a licensed electrical contractor who's installed dozens of them across New Jersey.
NJ Electrical Contractor License #6215a. Fully insured, fully permitted — the panel work, transfer switch, and gas hookup are all done to NJ code with the right inspections.
We install Generac standby generators across the full residential lineup — air-cooled Guardian series and liquid-cooled estate units. We know the products and the install playbook cold.
We pull the electrical permit, file with the utility, coordinate gas line work, and walk the inspection. You don't make a single phone call to the town — we do all of it.
Typical project timeline: 2–4 weeks from contract to switched-on, depending on permits and equipment availability.
We walk your property, check your gas line, panel, and load. You get a clear plan and an honest price.
We size the right Generac unit for your actual home — not what's easiest to sell. Fixed-price quote, no surprises.
We handle the permits, install the generator, the transfer switch, and the gas connection — usually in one to two days on-site.
We start the unit, simulate an outage, walk you through the Mobile Link app, and you're done. Power outages are now optional.
