What’s our difference?

Our difference at ARH Diesel Services is organising regular servicing and repairs in order to prevent future unplanned breakdowns and major issues. Being smart in managing your mechanical requirements with a regular maintenance schedule will save you time and money, reducing machinery downtime and onsite complications.


Some of the most costliest repairs can be due to a lack of ongoing maintenance and servicing. We aim to service your machines foreseeing faults and failures before they’ve occurred rather than a reactive approach when breakages happen.


We highly recommend following manufacturer’s recommendations on pre-planned scheduled servicing, as these preventative measures can save businesses on major repair costs if regular servicing isn’t maintained.


We schedule in the servicing of your machines based on the condition, parts and components. Various plant and equipment can require more or less attention given these factors. Having this in-depth knowledge and ongoing working history on your equipment allows us to keep costs down, which means your scheduled maintenance is more efficient and reduces overall downtime.
