Generators and transfer switches require at least annual maintenance. This helps ensure that they are ready to deliver power in an outage or emergency. Some of the most important elements of your generator maintenance plan should include the following services:

  • Annual fuel filtering and cleaning to remove water and microbes, especially for diesel-powered generators
  • Testing battery levels and ensuring adequate battery power for starting standby generators
  • Checking the coolant level for the generator cooling system
  • Electrical checks for voltage regulators

GenServe provides a wide array of maintenance services. Services designed to keep your backup generator operating at peak efficiency. This is to provide you with reliable power when your business needs it most.

At GenServe, we provide the most practical generator maintenance options for our clients. Our team is made up of more than 100 certified and experienced techs.

Over time, your generator can develop issues that could prevent it from operating effectively or at all in an emergency:

  • Belts, hoses, and other parts can deteriorate or crack over time. This could lead to breakdowns and a loss of power when it is required.
  • Cooling systems require regular inspections and replacement of coolant to function properly.
  • Engine oil can break down during periods of disuse. Regular oil and filter changes are essential to keep the generator running smoothly.
  • Diesel fuel can deteriorate and require replacement if left unused for a lengthy period of time.
  • Electrical connections should be tightened and checked for any damage.

Scheduling regular service with GenServe can help you to address these and other issues that could affect the performance and operation of your commercial generators. Our technicians are trained to conduct a 105-point inspection of your system. After that, we then perform commercial generator maintenance in accordance with NFPA 110 Chapter 8 guidelines, which ensures that you receive the right recommendations for your system.


Generator transfer switches can manually or automatically switches the electrical load from the primary power source to the generator when the power goes out. So, at GenServe, we sell, install and service open-transition, closed-transition, bypass-isolation and elevator-selector transfer switches to suit the needs of your company and to ensure the most seamless switchover during electrical outages.
