Your Lifeline in Power Outages

Your generator is more than just a backup system; it’s your lifeline during power outages. You guarantee that your property stays operational when the grid goes down. But to make sure your generator performs reliably every time, regular maintenance and timely repairs are vital.
At YellowBall Electric + Generators, we offer top-tier generator maintenance and repair services designed to keep your generator running smoothly every year. As a Generac Authorized Dealer, we provide specialized expertise, access to genuine parts, and a commitment to excellence that ensures your generator will be ready when needed.

What’s Included in Our Maintenance Services

We provide thorough maintenance services to cover every aspect of your generator’s performance. We specialize in servicing Generac models and other types of generators. Here’s what you can expect from us:

Full System Inspection

Our in-house and licensed electricians begin with a detailed inspection of your generator. We look at all key components and check everything from the fuel system and battery to the control panel and electrical connections.

Oil and Filter Changes

Generators require regular oil and filter changes to keep their engines running smoothly. During maintenance, we replace oil, air, and fuel filters to prevent dirt and debris from causing wear and tear on the engine. These changes can significantly improve the lifespan and efficiency of your generator.

Battery Testing and Replacement

The battery is the heart of your generator’s start-up process. We conduct a comprehensive test to ensure the battery is charged and functioning well. If it’s near the end of its life, we’ll replace it to prevent any issues when the power goes out. This approach ensures your generator always begins without a hitch.

Load Testing

Your generator should be able to handle your property’s full power demand during an outage. To ensure this, we conduct load testing to similar real-world conditions. This helps us verify that your generator can seamlessly take over during an outage without experiencing performance issues.

Safety Component Check

Here at YellowBall Electric + Generators, we prioritize safety. Our maintenance includes a detailed check of all safety systems, such as fuel lines, exhaust systems, and automatic shut-off features. To ensure these components are working properly, we help mitigate any risks of accidents or hazards when your generator is in use.

Software and Firmware Updates

We have excuse access to the latest software and firmware updates to ensure your generator runs as efficiently as possible. These updates also allow the generator to adapt to any new power demands on your property.
