The short answer
A good generator repair company tells you what failed and why, in writing, before it charges you for parts. It asks for your generator’s make, kVA and fuel before it travels, states its callout fee upfront, and guarantees its workmanship for a stated period.
Generators fail in different systems: the engine, the fuel supply, the cooling system, the alternator, the voltage regulator, the controller and the changeover switch. A company that can test all of them sends a technician who finishes the job, instead of a parts fitter who tries the most common spare first.
Price matters, but compare like with like. A low callout fee followed by guessed parts often costs more than a higher fee with a proper diagnosis. Ask each company the same questions and compare the written quotes side by side.
Before you book
You should get a figure or a range before anyone travels, with business-hours and after-hours rates stated separately.
A written quote should list the parts, the labour and the total before work starts. Ask whether the diagnosis is charged separately.
Ask for the technician’s trade or engineering qualifications, and whether they handle both engines and electrics.
Give the make, kVA and fuel from the data plate. A good company asks for them, and a vague “we do everything” tells you little.
Ask for a specific arrival time for breakdowns, and whether it applies after hours, on weekends and on public holidays.
Ask how long the workmanship guarantee lasts and what it covers, and make sure it appears on the invoice.
Qualifications
For engine, fuel and cooling work on diesel sets, look for a trade-tested diesel mechanic or a diesel plant fitter.
Alternator, AVR and controller faults need someone trained in electrical work, not only in engines.
Work that changes your building’s fixed wiring, such as a changeover switch or an ATS, should be done or signed off by a registered electrician who can issue a Certificate of Compliance (CoC).
Mechanical and electrical engineering training helps on faults where the engine and the electrics meet, such as a set that runs but will not carry the load.
Ask whether the company works on your brand regularly and whether it can get parts for it. Be wary of anyone who claims a manufacturer link they cannot show in writing.
Ask how long the company has repaired generators. A long track record means your fault is likely one it has seen before.
Warning signs
If the price is only verbal, you have nothing to hold the company to.
A company that replaces the battery or the AVR first and tests later is guessing at your cost.
Disconnecting a low oil pressure or high temperature shutdown to make a set run hides a real fault and can wreck the engine.
Without an invoice you have no record of the work and no way to claim the guarantee.
If nobody will tell you what the visit costs before they come, expect a surprise on the bill.
Ask to see the parts that were replaced. A company that will not show them gives you no proof they failed.
Use these lists when the paperwork arrives and when you read reviews. A company that ticks most boxes is easy to hold to its word.
