Service
Annual maintenance is the whole point
Most generators that fail during an outage were not broken. They were neglected. Stale fuel, a dead start battery, and a controller nobody has looked at in three years account for the majority of no-start calls we take. We service every brand, whether we installed it or not.
Scope of work
What an annual visit actually covers
- Engine service
- Oil and filter change, air filter, spark plugs or injector inspection, belt and hose condition.
- Cooling system
- Coolant strength and inhibitor test, radiator and louver clearance, block heater verification.
- Fuel system
- Diesel fuel sampling for water and microbial growth, gas pressure under load, regulator and line check.
- Starting system
- Battery load test, terminal service, charger output verification. Batteries are the single most common no-start cause.
- Electrical & controls
- Controller fault log review, alarm test, firmware status, torque check on load-side connections.
- Transfer switch
- Contact inspection, exercise cycle, timing verification, and confirmation the critical branch is what you think it is.
- Enclosure & site
- Rodent and nesting inspection, drainage, exhaust clearance, snow and vegetation setback.
- Documented run
- Loaded run with recorded voltage, frequency, and temperature readings, filed and sent to you.

Warranty
How a good generator becomes a brick
The common industry pattern is to oversize a unit, install it, hand over a manual, and leave maintenance entirely to the owner. Nobody explains that manufacturer coverage generally requires documented, on-schedule service by an authorized dealer, so when an alternator, controller, or engine component fails inside the coverage window, the claim is denied for want of records.
By year three that unit is running on fuel that has absorbed water, cranking on a battery that fails under load, and logging failed self-tests nobody reads. It looks fine from the driveway and it will not start when the utility drops. That is a brick on a concrete pad, and it is entirely preventable.
Every system we install leaves on a plan, and we will enroll a unit we did not install. You get documented loaded runs with recorded voltage, frequency, and temperature, battery load tests, fuel sampling, and a service history you can produce for a manufacturer claim, an insurer, or a regulator.
Why we engineer instead of oversize →The four usual causes of a no-start
- Stale or contaminated fuel, because diesel grows water and microbes in standby duty
- Start battery that reads fine at rest and collapses under cranking load
- Unread controller fault log hiding a year of failed exercise cycles
- Lapsed warranty because no documented service history exists
Enroll an existing generator
Send the make, model, and roughly when it was last serviced. We'll schedule an assessment visit and put it on a plan.
