Why Generator Aftermarket Support Matters

Protect Your Investment

Standby generators represent a significant investment in your property's protection and comfort. Nevertheless, without proper aftermarket support, that investment can quickly deteriorate. In particular, neglected maintenance voids manufacturer warranties, leaving you responsible for expensive repairs that should be covered.

Ensure Reliable Performance When It Matters Most

Michigan experiences severe weather throughout the year, from winter ice storms to summer thunderstorms. Therefore, your generator must start immediately during these critical moments. Regular aftermarket support ensures your system responds reliably during power outages, protecting your family's safety and comfort.

Extend Equipment Lifespan

Proper maintenance dramatically extends generator life expectancy. Similarly to how regular oil changes extend your vehicle's life, generator maintenance prevents premature wear and costly component failures. As a result, clients with maintenance contracts enjoy 50% longer equipment lifespans on average.

Reduce Long-Term Operating Costs

While some homeowners skip maintenance to save money, this approach actually increases costs over time. Conversely, preventive maintenance catches small issues before they become major repairs. In addition, well-maintained generators run more efficiently, consuming less fuel during operation.

What's Included in Our Maintenance Service

Our comprehensive generator maintenance visits go far beyond basic oil changes. Instead, we perform thorough inspections that identify potential problems before they cause failures. Moreover, each service includes:

  • Complete Visual Inspection – Checking for leaks, damage, corrosion, and wear on all components
  • Oil & Filter Change – Using manufacturer-recommended lubricants for optimal engine protection
  • Air Filter Inspection & Replacement – Ensuring clean airflow for efficient combustion
  • Spark Plug Inspection – Replacing worn plugs that reduce starting reliability
  • Battery Testing & Service – Checking charge levels and connections to guarantee reliable starts
  • Coolant Level & Condition Check – Preventing overheating that damages expensive engines
  • Fuel System Inspection – Examining lines, filters, and connections for proper fuel delivery
  • Electrical Connections Tightening – Loose connections cause intermittent failures and safety hazards
  • Transfer Switch Testing – Verifying automatic switching operates correctly during power loss
  • Load Bank Testing – Actually running your generator under load to confirm real-world performance
  • Control Panel Diagnostics – Checking error codes and system settings for optimal operation
  • Detailed Service Report – Documenting all findings and recommendations for your records

Emergency Generator Repair Services

Generator failures never happen at convenient times. Instead, they typically occur during severe weather when you need backup power most desperately. Consequently, we maintain 24/7 emergency service availability throughout Metro Detroit and surrounding communities.

Common Generator Problems We Repair

Our experienced technicians quickly diagnose and repair all generator issues, including:

  • Won't Start – Battery failures, fuel delivery problems, starter motor issues
  • Runs But Won't Produce Power – Voltage regulator failures, winding damage, control board issues
  • Shuts Down Unexpectedly – Low oil pressure, overheating, electrical faults
  • Transfer Switch Problems – Won't engage, stuck between positions, electrical failures
  • Unusual Noises – Bearing wear, loose components, exhaust leaks
  • Excessive Fuel Consumption – Carburetor problems, governor issues, air leaks
  • Error Codes & Warning Lights – System faults requiring diagnostic expertise

Frequently Asked Questions About Generator Aftermarket Support

Most manufacturers recommend maintenance every 6-12 months depending on usage. However, we typically suggest annual maintenance for residential generators and semi-annual service for commercial units. Additionally, generators that run frequently during testing or outages may benefit from more frequent service intervals.

No – in fact, the opposite is true. Manufacturer warranties specifically require regular maintenance by qualified technicians. Consequently, skipping maintenance can void your warranty coverage, leaving you responsible for expensive repairs. We provide documentation of all maintenance services to support your warranty claims.

Absolutely! We service all makes and models regardless of who performed the original installation. Moreover, many homeowners switch to our service because they're dissatisfied with their original installer's maintenance quality or availability.

During power outages and emergencies, we prioritize calls based on severity. Typically, we arrive within 2-4 hours for emergency situations. Meanwhile, we triage calls to help customers with critical needs first, such as medical equipment dependence or business operations.

While rare, some generators suffer catastrophic damage that makes repair uneconomical. In these cases, we provide honest assessments and replacement recommendations. Furthermore, we can help you understand your options and find the right replacement system for your needs and budget.

 

Also we have a rental generator fleet to assist during the time of need.

Yes! Our maintenance plans provide scheduled service at discounted rates plus priority emergency response. In addition, plan members receive reminders when service is due, ensuring you never miss critical maintenance. Contact us to learn about available plans and pricing.

Definitely. Many modern generators include remote monitoring capabilities that alert you to problems. Therefore, we can configure these systems and provide ongoing monitoring services. As a result, potential issues get identified and addressed before they cause failures.
