Why Regular Tune-Ups Matter for Your Standby Generator

Your generator sits idle most of the year, but when the power goes out, it needs to start immediately. We perform thorough tune-ups that include oil and filter changes, spark plug replacement, battery testing, and fuel system inspection. Our technicians check the automatic transfer switch operation and verify your unit can handle your home’s load requirements. We test under actual load conditions to catch problems before an outage happens.

Technical Service

What We Check During Every Tune-Up

We inspect all critical components including the voltage regulator, coolant levels, and belt tension. Our diagnostic equipment reads fault codes and monitors the control board for issues. We verify proper operation of the 200-amp automatic transfer switch and test the unit under load.

Common Questions

Residential Electrical FAQs

Common questions from Triangle homeowners about residential electrical services. Don’t see yours? Call us directly — we’re happy to help.
How often does my standby generator need a tune-up?
We recommend annual tune-ups for most residential generators. If your unit runs frequently during outages or you’re in an area with poor power reliability, consider service every six months. Generators that exercise weekly still need annual maintenance because they rarely run under actual load during those test cycles.
We change the oil and filter, replace spark plugs, inspect the air filter, test the battery and charging system, and check all fluid levels. We clean the unit, inspect wiring connections, test the automatic transfer switch, and run the generator under load. You’ll receive a detailed report of our findings and any recommended repairs.
The most common causes are dead batteries, stale fuel, or faulty automatic transfer switches. Batteries typically last three to four years. Gasoline degrades in about six months without stabilizer. We test the transfer switch relay and verify it’s sending the start signal. Regular tune-ups catch these issues before you lose power.
No, use only the oil specified in your owner’s manual. Most air-cooled generators require SAE 30 or synthetic 5W-30. Liquid-cooled units often need 15W-40 diesel oil. Using the wrong viscosity causes premature wear, especially during cold starts. We stock the correct oil for all major generator brands and change it during every tune-up.
Your generator should exercise for 15 to 20 minutes weekly. This keeps internal components lubricated and prevents fuel system problems. However, these short test runs don’t fully warm the engine or put it under real load. That’s why professional tune-ups are still necessary to verify performance and catch developing issues.

However, these short test runs don’t fully warm the engine or put it under real load. That’s why professional tune-ups are still necessary to verify performance and catch developing issues.
Routine tune-ups and maintenance don’t require permits. However, if we discover issues that need electrical repairs to the transfer switch or panel connections, we’ll pull the necessary permits. Any work involving modifications to your home’s electrical system must meet NEC Article 702 requirements and local codes for safe operation.
