“Last storm knocked out power for 4 days. Neighbors were miserable. We sat comfortable the entire time. Princeton Electrical maintained our Generac two months prior. Best money ever spent.”
“Called for routine service. Tech found my battery had completely lost capacity — would have failed the next outage. Replaced it on the spot. Genuinely saved us from a nightmare scenario.”
“Used a cheaper company first. Generator failed during a major outage. Switched to Princeton Electrical — completely different level of service. Worth every penny.”

#1 cause of failure. We load-test every battery and replace weak ones before they strand you.
Old oil causes engine seizure. Fresh oil at every service protects your engine.
Blocked filters starve the engine. We service air and oil filters every visit.
Stale gas and stuck regulators. Full fuel path inspection at every service.
Terminal corrosion causes silent failure. We clean and protect all contact points.
Fouled plugs cause hard starts. Inspected and tested every maintenance visit.
Transfer switch failure = no power. We test the full switching sequence every visit.
Storm-time service costs 3–5x normal. Annual maintenance eliminates that call.

Generac recommends annual service every 12 months or 200 hours — whichever comes first. Skipping a year risks voiding your manufacturer warranty and leaves hidden problems to worsen over time.
Most visits take 1 to 2 hours from arrival to completion. We walk you through our findings before we leave and hand you a written service report.
Absolutely. As an Authorized Generac Dealer we service all Generac standby models including units 10, 15, even 20+ years old. Older units often benefit most from annual maintenance.
We explain exactly what was found, what it means, and what it costs — before we touch anything. You decide. We never perform unauthorized repairs and only use genuine Generac parts.
Yes. Generators that sit idle are often in worse shape. Oil degrades, batteries self-discharge, fuel goes stale, rubber components dry out. Sitting idle 12 months is often harder on components than running during an outage.
