What affects the cost of Generator Maintenance 

Knowing the various aspects that influence the cost of maintenance of a generator can help you choose the correct generator when purchasing.

Mobile or Static unit  – If a generator is transported to your Local Pros partner’s workshop you will not incur the cost of a call-out fee making it cheaper, in general, to service a mobile unit compared to a static unit.

Diesel or Petrol units – Diesel generators tend to be slightly more costly to service than their equivalent petrol option but they also need to be serviced less often making them cheaper to maintain in the long run.

The cost of spare parts – The cost of service and replacement parts for some generator brands can be much more expensive than others. Additionally, some spare parts of lesser-known brands can be difficult to find and might incur additional charges for the time spent locating the required parts.

How big the Generator is – In general servicing, larger generators cost more than servicing smaller units as they tend to require more of everything. For example, a 10kVA generator can have double the oil capacity than that of a 5kVA generator.

Where the generator is located  – If you have a fixed generator and need to service it on-site where the generator is located will directly affect the cost of maintaining it.

How much does it cost to service my generator?

In South Africa, with the frequency of load shedding, backup generators typically run more frequently than under normal conditions. Like any equipment powered by a combustion engine, the more frequently it is used, the more frequently it requires maintenance.

For generators used as a backup during load shedding, our partners advise the following maintenance schedule:

Our partners recommend a monthly checkup that consists of

  • Cleaning of generator for Inspection
  • Inspecting oil levels 
  • Inspecting water levels 
  • Inspecting filters and draining water traps
  • Inspecting belts and tensioners 
  • Testing Battery 
  • General revision of generator 
  • Inspecting for any abnormalities or leaks
  • Inspecting Control Panel

The price of inspecting a mobile unit at a partner’s workshop will start at R500 and an inspection performed on-site might cost anything from R900 depending on the type and complexity of the generator.

Our partners recommend a quarterly service that consists of:

  • All of the previously mentioned monthly checks
  • Replacement of oil and oil filters
  • Cleaning or replacement of air filter

Minor service cost range from R1300+ for a service at one of our partner’s workshops or R1500+ when performed on-site. These prices will vary depending on the size of the unit and the cost of the service parts and fluids.

Our partners recommend a major annual service that consists of:

  • All of the monthly checkups and quarterly maintenance 
  • Checking of fuel lines 
  • Checking and adjustment of valvetrain 
  • Checking of the fuel tank 

A major service can cost from R2500.00+ for mobile units serviced at a partner’s workshop with prices for a major service of a fixed unit performed on-site starting at around R2800.00+ These prices will vary depending on the size of the unit and complexity of the service.

Note: After the initial run-in period, don’t forget to get your generator serviced and the valves checked. Usually, small diesel generators have a run-in period of 30 hours and petrol generators 10 hours.
