How Your Generator Repair Visit Works
Generator service should be thorough because the equipment is only worth what it delivers during an outage.
A generator visit covers the engine, the electrical components, the automatic transfer switch, and the controls, with a live-load test at the end to confirm the system actually responds during a real outage.
You phone us or submit service online. Our team collects specifics about your generator (brand, approximate age, what symptoms you’re experiencing, whether the unit is under warranty) and confirms an appointment.
Your licensed electrician inspects the generator’s engine, electrical components, automatic transfer switch, and controls. You receive a written quote laying out the repair scope before the electrician starts the work.
Your electrician completes the repair and runs the generator through a full test cycle, including automatic transfer switch operation, to verify the system actually responds correctly to a real outage condition.

Frequently Asked Questions
How often does my standby generator need professional service?
Most standby generators need annual professional service to stay ready for real operation. Higher-use units or older equipment can benefit from twice-yearly service. Generac and most other manufacturers specify service intervals in the owner’s manual, and following them is typically a warranty requirement.
Why didn’t my generator start during the last outage?
The most common cause is a battery that failed between outages, followed by fuel supply issues (a closed valve, empty propane tank, or fuel line problem) and exercise failures that went unnoticed. An annual professional service test under load catches most of these conditions before an actual outage.
Should I do my own generator maintenance?
Oil and filter changes are within some owners’ ability, but comprehensive service requires a licensed electrician with generator training. Transfer switch testing, battery diagnostics, fuel system verification, and control module evaluation all require specific expertise. DIY maintenance often misses the most important checks.
How long do standby generators last?
A well-maintained residential standby generator typically runs 20 to 30 years or more. Usage hours affect lifespan significantly, which is why exercise cycles are counted and tracked. Neglected units that miss service intervals often fail far sooner, usually during an actual outage when the failure matters most.
Can you service all standby generator brands?
Yes. Princeton Air’s licensed electricians service the residential standby brands installed throughout New Jersey, including Generac, Kohler, Cummins, Briggs & Stratton, and others. Generac specifically is a significant portion of our generator service volume because of how common the brand is in the region.
