Generator Maintenance

Backup Power When You Need It

Why Generator Maintenance Matters

Over time, your generator can develop issues that could prevent it from operating in an emergency. 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.

At GenServe, we consider generator maintenance the most important thing we offer. Our technicians are trained to conduct a 105-point inspection of your system and perform maintenance in adherence with NFPA 110 guidelines. This enables us to make the best recommendations for your system and keep it in compliance with local code requirements.

Preventative Maintenance / Service Plans (Yearly, Semi-Annual & Quarterly)

Minor Service: Typically performed quarterly or as frequently as weekly or bi-weekly depending on the type of facility and industry that you operate. This is a visual inspection that covers important checks such as the air filter, coolant level, condition & operation of fan belts, block heater, flex connections & mountings, battery, battery charger, governor linkage and louvers. Lubricate necessary fittings. Check oil level and condition. Check battery voltage and age. Repair possible (minor) coolant, lube and fuel leaks. Inspect day tank, fuel levels and pump controls. Check all bulbs and replace any if needed. Simulate each safety shutdown.

Building Load Test: When permitted, a building load test is highly recommended. This is done by simulating a power outage. The technician will manually shut off utility power triggering the transfer switch to run the generator automatically. This ensures equipment functionality during a possible power outage, the time it takes for the equipment to recognize an outage has occurred and the time the transfer switch tells the backup power generator to run.

Major Service: Typically performed once a year, or after a generator has been running continuously for a long period of time during extended power failure. This major service includes everything that the minor service offers plus a complete change of lubricating oils and oil filters. Oil and coolant samples for lab analysis, inspection of spark plugs and coils.

Load Bank Test: A load bank is a device that allows you to test the output of your generator by simulating the actual load of an electrical system and can be used to test the system’s ability to generate power and maintain voltage and current levels within specified limits verifying that the system is capable of supplying the power required to run your business during a power outage.

Transfer Switch Maintenance Helps Keep the Power On

In addition to maintaining your commercial generator, you must maintain the switch responsible for transferring the power to it in an emergency. Generator transfer switches can manually or automatically switch the electrical load from the primary power source to the generator during a power outage. At GenServe, we sell, install and service open-transition, closed-transition, bypass-isolation and elevator-selector transfer switches as part of our promise to provide a full suite of backup power services. We have the switches to suit the needs of your company and to ensure the most seamless switchover during electrical outages.

Generator Fuel Polishing and Maintenance

Over time contaminants and sludge build up in the fuel tank of your backup power system. This foreign matter can clog filters, reduce engine performance, create carbon deposits, cause incomplete combustion and loss of power, and simply wear down fuel system components.

Fuel polishing removes these contaminants from the bottom of the tank and adds a fuel catalyst. The fuel is then circulated through a fuel conditioner and a series of filters that will clean and restore the fuel to a clear and bright condition — saving you fuel costs and ensuring the generator engine will operate efficiently at a moment’s notice.

Proper maintenance of the UPS and the generator, which act together as the heart of your emergency power backup system, keep power pumping through your buildings without a flicker.

GenServe can provide UPS Service as a part of any maintenance package.

Backup Commercial Generator Load Bank Testing

You don’t want to find out that your backup generator cannot handle the electrical load of your facility when you try to use it in an emergency. Through load bank testing, we can test your backup generator’s capabilities and make sure it will be prepared to handle the full force of your facility’s energy needs when needed.
