January 7, 2025

Standby power generators have become an important part of many Wisconsin homeowners' indoor comfort and safety plans. How long do backup generators last? Professional Services, the leader in residential and commercial generator services in Random Lake, WI, provides the following information about generator care and the importance of preventative maintenance.

Why Generators Need Professional Maintenance

Preventative maintenance involves regular inspections, tune-ups, and service tasks to ensure a backup generator operates efficiently throughout its useful lifespan. When you consider the investment you've made in your family's safety and comfort by installing a reliable generator, the marginal cost of regular maintenance is an easy call.

Overlooking maintenance leads to costly repairs, reduced efficiency, and risks of complete system failure during critical moments. Take the right approach to maintenance to maximize reliability when you need it most.

Key Benefits of Generator Preventative Maintenance in Random Lake, WI

Invest in inexpensive professional generator maintenance for substantial benefits:

Extended lifespan. Regular maintenance helps generators last longer.
Optimal efficiency. Expert maintenance increases fuel efficiency and consistent power output — critical in the event of extended power outages.
Safety and reliability. Expert technicians can identify potential hazards like fuel leaks or electrical issues during maintenance visits. Enjoy assurance that your system will work safely and effectively when needed.
Cost savings. When technicians catch small issues early, you'll avoid expensive repairs later, potentially after a dangerous system failure.

How Long Do Backup Generators Last?

The lifespan of a backup generator depends on several factors, including maintenance frequency, usage hours, and operating conditions. Like any piece of complex machinery, generators have specific use guidelines that involve proper load capacity management to avoid unnecessary strain and wear.

The best way to ensure your standby generator will last as long as possible is to schedule regular professional maintenance services.

Top-quality Generac generators can provide up to 30 years or more of reliable service with proper care and maintenance.

At each scheduled maintenance service visit, Authorized Generac Dealers and Service Providers follow a detailed checklist to ensure the system remains reliable, efficient, and safe.

The tasks include:

Oil and filter changes. Ensure proper lubrication and check for signs of contamination.
Air filter and spark plug inspection. Make sure you have optimal airflow and engine performance with effective ignition power.
Battery maintenance. Test for performance and voltage levels and clean the terminals.
Fuel system inspection. Check for leaks, clogs, or damage. Test fuel pressure and clean fuel filter.
Coolant system and heat management. Examine coolant levels and top off as needed. Check radiator hoses and connections for leaks or wear.
Electrical system evaluation. Test automatic transfer switch (ATS), inspect all electrical connections for tightness and corrosion, and verify output voltage, frequency, and phase balance.
Load capacity testing. Simulate power loads using a load bank and evaluate real-time performance under load conditions.
Exhaust system check. Inspect for blockages, leaks, or excessive carbon buildup.
Operational testing. Run the system through a full-cycle operational test and monitor for unusual noises, vibrations, or irregularities during operation. Verify the function of all safety features.
Housing and environmental maintenance. Inspect the housing for damage, rust, or wear and clear debris, leaves, or obstructions to maintain proper ventilation. Lubricate or coat exposed parts as needed.
Software updates and diagnostics. Update firmware or software as necessary and use diagnostic tools to identify and address any hidden faults or warnings.
Final report and recommendations. Provide the owner with a detailed report of the maintenance service with any recommendations.

Essential Preventative Maintenance Tasks for Property Owners

In addition to regular professional maintenance, Wisconsin homeowners should provide manufacturer-recommended maintenance, often including:

Oil changes. Maintain lubrication and prevent engine wear.
Air filter cleaning. Dirty filters can choke your generator, reducing efficiency and causing overheating.
Fuel stabilization. These help to prevent stored fuel from degrading over time.
Visual inspections. Regularly check for leaks, loose connections, and signs of wear.

Consider running your generator under load for 10 to 15 minutes monthly to make sure all components are functioning and to prevent moisture buildup.
