When our backup generator failed during a winter storm, Wolverine had a technician on-site in 90 minutes. He diagnosed a failed fuel pump and had us back online within 3 hours. That kind of response protects our patients and our reputation. We've been using their preventive maintenance program for 5 years now and haven't had a failure since.
We run three shifts, 24/7, and cannot afford downtime. Wolverine's bi-annual maintenance program keeps our 500kW Caterpillar generator in perfect condition. Their technicians are professional, thorough, and always on time. Last year they caught a coolant leak during routine service that would have caused a catastrophic failure. The preventive maintenance pays for itself many times over.
Our data center requires annual load bank testing for compliance, and Wolverine handles it flawlessly every time. They bring their mobile load bank, run our generator at full capacity, document everything, and provide detailed reports for our audits. Their technicians understand the critical nature of our operations and schedule testing during maintenance windows to avoid any risk to uptime. Outstanding service.
As a township, we operate generators at our water treatment plant, fire stations, and emergency operations center. Wolverine maintains all seven units under a master service agreement. Their record-keeping is excellent, their response times are reliable, and their technicians are extremely knowledgeable. They helped us secure grant funding by providing detailed maintenance histories and compliance documentation. Highly recommended for municipal applications.
Our facility has a 150kW diesel generator that sits idle most of the year. Wolverine's fuel polishing service keeps our diesel tank clean and ready. They test the fuel, remove water and contamination, treat for algae growth, and provide lab reports. Last month when we had a planned power shutdown for electrical work, our generator ran perfectly for 8 hours straight because the fuel was pristine. This service is essential for standby generators with stored diesel fuel.
Our 22kW Generac stopped working during a late-night ice storm. I called Wolverine's emergency line at 11 PM and they had someone at my house in Northville by 1 AM. The technician fixed a bad battery and faulty transfer switch connection. He was professional, knowledgeable, and had our power back on quickly. We signed up for their annual maintenance plan the next day—worth every penny for peace of mind.
Typically within 2 hours, 24/7, with fully stocked trucks for first-visit fixes.
Annual/semi-annual plans including system inspections and fluid changes.
We service all makes and models of generators, not just Generac. Cummins, Kohler, Caterpillar, Blue Star, Onan, and more!
Yes, mobile units serve Marquette and all of the Upper Peninsula with full compliance reporting.
Our comprehensive preventive maintenance visits include oil and filter changes, coolant system inspection, battery testing and cleaning, fuel system inspection, air filter replacement, load testing (annual), transfer switch inspection, connection tightening, complete visual inspection of all components, and a detailed service report with photos and recommendations. We test your generator under load to verify performance, check for fluid leaks, inspect belts and hoses, verify all safety systems, and document maintenance in our system for warranty compliance. Most maintenance visits take time depending on generator size. All work is performed by factory-certified technicians with specialized training on your generator's brand and model.

Yes, we offer two preventive maintenance agreement levels. Level 1 includes one annual comprehensive service visit with oil/filter changes, complete inspection, and priority emergency service. Level 2 includes two visits per year (spring and fall) with comprehensive service, load bank testing, and priority scheduling.
Contracts are available for single generators or multi-unit facilities across Michigan. We service industrial, commercial, and residential generators. Regular maintenance reduces emergency breakdowns by 90% and extends equipment life by 5-10 years.
Commercial generators in Michigan should be serviced at minimum twice per year—ideally in spring (April-May) and fall (September-October). Generators that run frequently (weekly tests, regular use) or support critical facilities (hospitals, data centers, manufacturing) benefit from quarterly service. Michigan's harsh winters with freezing temperatures make fall service critical to ensure cold-weather reliability. Spring service addresses any winter damage and prepares systems for storm season. Annual load bank testing is required for most commercial facilities to meet NFPA 110 compliance. If your generator experiences high runtime hours (500+ hours annually) or operates in demanding environments, monthly inspections may be warranted.
We provide generator service coverage throughout all 83 Michigan counties from four strategically located facilities. Our Zeeland location (headquarters) serves West Michigan including Grand Rapids, Kalamazoo, Holland, and Muskegon. Our Wixom facility covers Southeast Michigan including Detroit Metro, Ann Arbor, Lansing, and Flint. The Gaylord location serves Northern Michigan including Traverse City, Petoskey, Cadillac, and Alpena. Our Marquette facility covers the entire Upper Peninsula. We typically arrive on-site within 2 hours for emergency calls in metro areas and within 4 hours for rural locations. Our mobile service trucks are fully stocked with common parts for all major generator brands, enabling first-visit repairs in most situations.
Absolutely. Our emergency service trucks are equipped to work during power outages with portable lighting, battery-powered diagnostic equipment, and generators to power our tools if needed. We perform emergency repairs while your generator is running to keep critical systems operational. For facilities with redundant generators (N+1 configurations), we can service one unit while others carry the load. If your generator has failed during an outage and cannot be repaired immediately, we can arrange emergency rental equipment to maintain power while completing repairs. Our 24/7 emergency service is specifically designed for power outage scenarios—we're ready to respond when Michigan storms cause widespread electrical failures.
Emergency generator service costs in Michigan vary based on several factors: the nature of the fault, your generator's size and brand, parts required, and your location relative to our nearest facility. After our technician diagnoses the issue, we provide a clear estimate before any work begins. For non-emergency maintenance visits and service contracts, we offer competitive flat-rate pricing — call 1-800-485-8068 to discuss your specific equipment and situation.
