Generac Generator Maintenance in Southeastern Wisconsin

When the power goes out, your standby generator is your first line of defense against unexpected outages. Regular maintenance is essential to ensure your generator performs reliably, safely, and efficiently when you need it most. At Mr. Holland’s Heating & Air, we provide comprehensive generator maintenance services to homeowners throughout Southeastern Wisconsin. Whether you have a Generac system or another brand, our experienced technicians will keep your equipment in peak condition year-round.

Why Generator Maintenance Matters

Your generator sits idle most of the time, but when an outage strikes, it has to be ready to run for hours—or even days. Routine maintenance helps prevent unexpected breakdowns, extends the life of your equipment, and protects your investment.

Benefits of regular generator maintenance include:

• Improved reliability and performance
• Reduced risk of costly repairs
• Compliance with manufacturer warranty requirements
• Safer operation and peace of mind
• Longer system lifespan

What’s Included in Our Generator Maintenance Service

Our detailed generator tune-up and inspection process ensures your system is ready for any emergency. During a maintenance visit, our technicians will:

• Inspect the fuel system, connections, and lines
• Check oil levels and change oil if needed
• Replace filters and spark plugs as recommended
• Test battery condition and charging system
• Inspect and tighten all electrical connections
• Run the generator to confirm proper operation
• Verify automatic transfer switch function
• Check for error codes or diagnostic alerts
• Clean and clear debris around the unit

After the service, we’ll review your generator’s condition with you and recommend any additional repairs if needed.

How Often Should You Service Your Generator?

For most standby generators, annual maintenance is recommended, along with periodic self-tests (usually weekly or bi-weekly) that the system performs automatically. If your generator runs for extended periods during outages, more frequent inspections and oil changes may be needed.

Our team can help you set up a maintenance schedule that fits your system’s usage and the manufacturer’s guidelines.
