What Is the Average Lifespan of a Gas Generator?


The lifespan of a gas generator depends on many factors, including the maintenance quality, maintenance frequency, and the quality of the generator’s installation.

It is safe to assume that the average lifespan of a gas generator can be anywhere between 10,000 to 25,000 hours.

Natural gas generators, as opposed to diesel generators, require more routine service and more frequent maintenance cycles.

Factors on Which Gas generator’s Life Depends

It is important, therefore, to understand what proper maintenance consists of in order to extend the lifespan of a gas generator.

Right Installation

It is crucial to ensure that the installation is adequate in the first place.
Optimal conditions to prolong the lifespan of a gas generator include having an enclosure for the unit.

The enclosure should be spacious and cleaned on a frequent basis.

Furthermore, there should be adequate airflow in the enclosure.

Another aspect to consider is protecting the enclosure against ground flooding, as well as securing it and restricting the access of unauthorized personnel.

Component Availability

Another aspect that is crucial to the average lifespan of a gas generator is the availability of the components.

Repairing and providing proper maintenance to the unit is crucial, as it can prolong its life and cut expenses in the long-term.

Some people use their generators more often than others. Thus, the average lifespan of a gas generator that incurs frequent use without proper maintenance can go down.

Preventive maintenance and the service times are dependent upon the engine hours and the time periods when the generator is in use.


Furthermore, maintenance cycles also depend on the environment. When conditions are humid, dusty, or extremely cold/hot, the generator needs to be maintained more often.

A visual inspection is a quick way of deciding how often the unit needs to be serviced.

It should be checked monthly for cleanliness or rodents if it is enclosed.

The coolant thermal-protection level also needs to be verified every six months.

Another step is to check the level of the oil and keep it at the full mark as much as possible without overfilling the container.

Additionally, gas generators need to be examined for leaks or any damage regarding the fuel-supply piping.

The terminals and wiring should not have any damage, corrosion, or loose clamps or connections.

Inspections and Maintenance

Apart from monthly checks, it is recommended to conduct semi-annual inspections and annual maintenance.

Every six months, the drive belts need to be checked for condition and tension, along with testing the coolant.

Furthermore, once per year, the gas generator needs to be serviced by a specialist. The specialist should cover aspects such as changing the oil and filter, as well as checking the alternator and the transfer switch.

In the end..

All in all, the average lifespan of a gas generator can be extended with appropriate maintenance and service.

This also depends on the availability of the components and how often the generator is used. For best results, monthly, semi-annual, and annual checks need to be conducted.
