Generator Maintenance

Annual Generator Tune-Up — Protect Your Investment, Guarantee Your Power

Factory-certified technicians service all major brands. Complete tune-up — oil, filters, plugs, battery, and load test — at nonprofit dealer cost pricing.

Why Annual Maintenance Is Non-Negotiable

A generator that sits unused for months still experiences oil degradation, battery discharge, and fuel system buildup. The most common reason generators fail during outages is not age — it is skipped maintenance.

Without Annual Service

  • Oil breaks down and contaminates the engine
  • Battery self-discharges below starting threshold
  • Fuel stabilizes into varnish, clogging carburetors
  • Air filter restricts airflow and reduces output
  • Manufacturer warranty may be voided

With Annual Service

  • Clean oil protects the engine between run cycles
  • Battery confirmed at full capacity before storm season
  • Fuel system inspected and stabilizer added as needed
  • Full load test confirms real-world power output
  • Written service record supports warranty claims

Generator Maintenance — Frequently Asked Questions

How often should a standby generator be serviced?

Standby generators should receive a full professional service once per year, regardless of how often they have run. Generators that ran heavily during a storm season — or any unit that logged more than 100 hours — may benefit from a mid-year inspection as well. Annual service is the single best thing you can do to protect your investment and ensure the generator starts every time you need it.

What is included in an annual generator tune-up?

Our comprehensive annual service covers an engine oil change with filter replacement, air filter inspection and replacement, spark plug replacement, battery load test and terminal cleaning, coolant level check, fuel system inspection, automatic transfer switch test, full load test under operating conditions, and a written service report you keep for warranty purposes.

How much does generator maintenance cost?

Maintenance pricing depends on the generator brand, size, and your service area. Because we are a 501(c)(3) nonprofit, our customers receive dealer cost pricing on all parts and labor — typically lower than commercial service competitors. Contact us for an exact quote; we will give you a firm price before any work begins.

Why is professional generator maintenance important?

The most common reason generators fail during a power outage is deferred maintenance — stale oil, a dead battery, or clogged filters. A generator that sits idle through the year still experiences oil degradation, battery discharge, and fuel system buildup. Professional service catches these issues before they leave you without power during an emergency. Regular maintenance also preserves your manufacturer warranty.

Can I perform generator maintenance myself?

Homeowners can handle the weekly self-test and basic visual inspections. However, the annual tune-up involves high-voltage components and factory-specific procedures that require certified training. Performing certain services yourself can also void your manufacturer warranty. Our factory-certified technicians have the tools and training to service your unit correctly and safely.

Do you offer generator service plans?

Yes. We offer annual maintenance plans that lock in your service appointment and pricing for each year. Most of our customers stay on plan for an average of five years after installation. A maintenance plan ensures your generator is never forgotten and gives you priority scheduling during high-demand periods like storm season.

Schedule Your Annual Tune-Up

Don't wait for storm season to find out your generator won't start. Book service now and have peace of mind before the next outage.
