Quotes, Call-Out Fees & Costs

How do you provide quotes, and is there a call-out fee for mobile work?

Costs depend on distance, the type of equipment, and how long diagnostics take. The quoting process generally works like this:

  • Initial phone assessment
    A brief discussion to understand the symptoms.
  • Estimated cost range
    A ballpark figure may be provided so you know what to expect.
  • On-site diagnosis
    The technician identifies the fault using scan tools and testing equipment.
  • Final itemised quote
    Based on the actual issue found and parts required.

A call-out fee may apply depending on your distance from Maitland and the type of vehicle or machinery. This is discussed upfront before booking.

Warranty & Workmanship

What warranty do you offer on parts and workmanship?

All new parts supplied carry the standard manufacturer warranty. Workmanship on electrical repairs is completed to a professional standard, with transparent communication about the condition of wiring, components and any contributing factors. Given the nature of older machinery or previous repair attempts, warranty terms vary depending on the job and existing system condition.

 

For work requiring specialist components, warranty inclusions may be outlined in the quote prior to commencement.

Commercial & Fleet Support

Do you provide scheduled maintenance and fleet servicing for transport, civil or agricultural operators?

Yes. Many commercial clients prefer scheduled, preventative electrical maintenance to reduce breakdowns and keep critical machinery working. Support may include:

  • Regular system checks
  • A/C inspections
  • Diagnostic fault scans
  • Battery, starter and alternator testing
  • Lighting and safety system checks
  • On-site servicing intervals aligned with vehicle use

This keeps fleets compliant and reduces the risk of unexpected downtime.

Qualifications & Industry Experience

What qualifications do your auto electricians and mechanics hold?

The business is operated by a qualified tradesman with:

  • Certificate III in Heavy Commercial Vehicle Mechanical Technology
  • Certificate III in Automotive Electrical Technology
  • Air Conditioning Handling Licence (ARCtick recognised)
  • 15+ years of industry experience working on heavy diesel, machinery and auto electrical systems (since 2010)

Training and experience directly align with the services offered, particularly diagnostics, A/C electrical faults and diesel electrics.

General FAQs

Can you diagnose issues over the phone?

Basic guidance may be provided over the phone, but accurate diagnosis requires on-site testing with scan tools, load testing equipment and electrical measurement tools.

This is a fully mobile service with storage facilities in Sandy Hollow and coverage across Maitland and surrounding regions.

This is common. Many repairs involve correcting incomplete or incorrect work from previous attempts. The technician will assess the system from scratch to ensure no steps were missed.
