When the power goes out, your Generac generator becomes more than just a machine—it’s your home or business’s lifeline. But like any piece of equipment, it needs regular attention to keep running smoothly. Preventative maintenance performed by a Certified Generac Technician is the best way to ensure reliability, extend the lifespan of your system, and protect your warranty.
In this post, we’ll share expert tips from certified professionals on how to keep your Generac generator ready to perform when you need it most.
Why Preventative Maintenance Matters
Generators are complex systems that rely on fuel, batteries, and multiple electrical components working together. Skipping maintenance might not show immediate problems, but over time it increases the risk of costly repairs and untimely breakdowns.
Certified Generac Technicians are trained specifically on Generac products, which means they follow factory-recommended procedures, use approved parts, and understand how to identify small issues before they become major failures. Regular maintenance not only ensures peace of mind, but also keeps your warranty intact.
Expert Preventative Maintenance Tips
1. Schedule Annual Inspections
The most important step in keeping your generator reliable is to have it inspected at least once a year by a certified technician. During these inspections, professionals will check engine performance, transfer switches, control panels, and fuel connections to make sure everything is working as it should.
2. Run Weekly Exercise Cycles
Your generator is designed to “exercise” itself automatically once a week. This process keeps the engine lubricated, ensures the battery remains charged, and helps spot any irregularities early. If you notice your system isn’t completing its exercise cycle, call a technician to have it checked.
3. Monitor Oil and Coolant Levels
Just like a car engine, your generator requires the proper oil and coolant levels to operate efficiently. Neglecting this step can lead to overheating or engine wear. Certified technicians will test and replace fluids as part of routine service, but homeowners should keep an eye on levels in between visits.
4. Replace Filters and Spark Plugs on Schedule
Dirty filters and worn spark plugs reduce performance and fuel efficiency. Regular replacements—done with Generac-approved parts—help maintain smooth operation and prevent unnecessary strain on the engine.
5. Inspect Battery Condition
A weak or corroded battery is one of the most common reasons generators fail to start. Certified technicians check voltage, terminals, and charging systems to ensure your generator is ready to go the moment it’s needed.
6. Keep Surrounding Area Clear
Leaves, snow, and debris can block airflow and create hazards around your generator. Make sure the area around your unit stays clean and unobstructed so it can function properly in all weather conditions.
