Preventative Generator Maintenance & Service Plans

Why it Matters

Annual maintenance is the difference between a generator that works and one that fails when you need it. Your system might run fine during its weekly 15-minute self-test, but that doesn’t stress the engine under full load or reveal problems developing beneath the surface. We perform resistance checks on rotors and stators, pressure-test cooling systems, verify DC excitation circuits, and calibrate voltage/current output: diagnostic procedures that require specialized equipment most companies may not have. We find corroded transfer switch contacts, weak batteries showing good voltage but failing under load, coolant that’s lost protective properties, and controller firmware bugs that cause failures during actual outages. These issues don’t show up during a 15-minute weekly test. They reveal themselves at 2am during a blizzard when your family needs heat. Our comprehensive service catches the problems before they become emergency failures, keeping your investment reliable and your family protected.

Real-World Scenario

Think of generator maintenance like changing your car’s oil. You can skip it and the engine might run fine for a while… until it doesn’t. We see generators that haven’t been serviced in years: batteries that won’t crank the engine, oil turned to sludge, air filters clogged with debris, and control boards with corroded connections. These systems might pass their weekly self-test, but they fail during real outages when families need them most.

Factory-Certified Technicians & Specialized Equipment

Our maintenance service requires tools and training many companies don’t maintain: cooling system pressure testers, rotor/stator resistance meters, gas pressure manometers, voltage calibration equipment, and comprehensive diagnostic software.

We’re Generac and Kohler factory-certified with 30 years of generator-exclusive experience. This isn’t a side service: it’s what we do, day in and day out.
