Question 1

How do I know if my generator needs maintenance?

Accepted Answer

If it's been more than a year since your last service visit, it needs maintenance — regardless of how often it runs. Generators that sit idle are just as susceptible to battery failure, oil degradation, and worn components as heavily used ones.

Question 2

What's the risk of skipping a year?

Accepted Answer

The biggest risk is finding out during an outage. A generator that passes its weekly self-test can still fail under load due to a weak battery, degraded oil, or a failing transfer switch — none of which the self-test catches. Annual maintenance eliminates that uncertainty.

Question 3

How long does a maintenance visit take?

Accepted Answer

Most visits take one to two hours depending on the unit and what we find. We'll confirm a time window when we schedule and let you know if anything requires a follow-up.

Question 4

What's included in an annual maintenance plan?

Accepted Answer

All plans include a full maintenance visit covering oil and air filter replacement, spark plug change, battery inspection, transfer switch inspection, and gas fittings check. Higher tier plans add priority scheduling, service discounts, and additional visits. See our Air-Cooled or Liquid-Cooled pages for full plan details.
