Generator Installation in Princeton, NJ
Certified Generac Installers Serving Princeton Since 2008
When a nor’easter or summer storm knocks out the grid, a standby generator restores power automatically within seconds. Princeton Electrical Makeover has handled residential electrical work throughout Princeton and surrounding Mercer, Middlesex, Somerset, and Monmouth Counties since 2008. As a certified Generac installer with factory-specific training, we size, install, and commission standby generators to manufacturer specifications, helping keep your warranty intact from day one.
Generator installation is licensed electrical work. It requires integrating the unit with your home’s panel and installing an automatic transfer switch that monitors utility power and signals the generator the moment an outage begins. Our team manages every step, from load calculation through final inspection, so nothing is handed off to a general contractor or multi-trade crew adding generators as a side service.
We offer free estimates, including virtual estimates by video call, and we’re available 24/7. Call (609) 834-5524 to schedule yours.
Why Princeton Homeowners Choose Princeton Electrical Makeover
Generac’s certified installer designation requires rigorous factory training. Our technicians have direct access to genuine Generac parts and current technical support, and every installation meets the exact specifications Generac requires to honor its manufacturer warranty. A non-certified installation can void that warranty.
We use advanced load-calculation tools to size your system accurately. Not ballpark estimates: actual wattage tallies for your HVAC, appliances, and lighting so the generator handles your home’s full demand without strain. Gas and electrical connections meet local building codes and Generac safety specifications. Our team shows up on schedule, uses protective footwear and floor mats, and leaves your home the way we found it.
Our certified background extends beyond Generac. We’re also certified installers for Tesla Wall Connectors, Tesla Powerwalls, and Span smart panels, which reflects the same factory-trained, safety-first standard we bring to every project. We’ve earned Angie’s List awards in 2023, 2024, and 2025, and we back every installation with strong warranties and transparent pricing with no hidden fees.

What a Standby Generator Powers in Your Home
The right standby generator keeps your household running through an extended outage, not just the lights. Systems can be configured for essential-circuit coverage or full whole-home backup depending on your needs and budget. Essential-circuit setups protect the loads that matter most at a lower equipment cost. Whole-home systems can cover the entire home, depending on the system design and load requirements.
A home generator installation in Princeton can be sized to power any combination of the following:
- HVAC systems (heating and cooling)
- Sump pumps
- Refrigerators and freezers
- Medical equipment
- Microwaves and dishwashers
- Televisions and computers
- Indoor and outdoor lighting
- Garage door systems
- EV charging systems
- Electric gate systems
- Washing machines and dryers
- Motion detectors
Standby systems run on natural gas or propane and connect directly to your electrical panel through an automatic transfer switch. There’s no manual startup, no extension cords, and no mid-storm refueling. Power comes back on its own.
What Our Generator Installation Includes
We handle both whole-home standby generator installation and portable generator installation, and our team has extensive experience with all major makes and models. A full residential standby installation is a multi-phase project, and we manage every part of it.
Load Assessment & Generator Sizing
Before we recommend a unit, we perform a complete on-site load assessment: tallying the wattage of every circuit and appliance you want protected. Online sizing calculators are a starting point, not a substitute for this step. Undersizing a generator causes it to shut down under load; oversizing wastes fuel and increases upfront cost. We size to fit your home accurately.
Permit Coordination & Site Preparation
New Jersey residential generator installations require a construction permit from your local municipality. The work must be performed by a licensed contractor and pass inspection. We handle permit coordination on your behalf. Site selection also follows local setback and clearance requirements: the generator must be placed with proper distance from windows, doors, and gas meters, and with clear fuel access.
Electrical Panel Integration & Transfer Switch Installation
Every transfer switch and power connection we install is seamless, safe, and up to code. The automatic transfer switch is what makes a standby generator automatic: it monitors utility power continuously and signals the generator within seconds of an outage, then switches back once utility power is restored. We integrate it with your electrical panel cleanly, with no improvised wiring.
Fuel Line Connection & Final System Test
We complete all natural gas or propane connections to code, then perform a full system test and homeowner walkthrough before we consider the job done. You’ll know exactly how the system operates and what to expect during an outage before we leave the property.
