What a Service Visit Usually Covers
- Oil and oil filter change, air filter, spark plugs on the manufacturer’s schedule
- Battery test and terminals cleaned. The battery is the most common reason a unit will not start.
- Check the transfer switch with a simulated outage
- Look for rodent nests, debris and wasp nests in the enclosure
- Read fault codes and update the controller if needed
- Check that the exercise schedule is set
What It Costs
HomeGuide puts generator maintenance at $200–$650 per year. Many installers sell yearly plans. Ask what is included, especially whether parts like batteries are extra.
Warning Signs
| Sign | What it can mean |
|---|---|
| Status light red or yellow | A fault the controller has logged |
| No exercise run heard in weeks | Schedule lost, battery dead, or controller fault |
| Long cranking before it starts | Weak battery, fuel supply issue |
| Oil on the pad | Leak to fix before an outage |
| Unit runs but the house does not transfer | Transfer switch problem |
Timing for Green Country
Spring brings severe thunderstorms and winter can bring ice. A service visit in late winter and another before the hottest part of summer covers both. After a long outage, have the oil changed even if the schedule says it is not due.
Warranties
Manufacturer warranties often depend on registration and documented maintenance. Keep the records. If a dealer installed the unit, ask whether it must also do the service to keep the warranty.
Older or Orphaned Units
If you bought a house with a generator already installed, ask for a full inspection. Check the model and age, whether parts are still available, and whether the transfer switch and permits were done properly.
