Inspection charges
Ask whether there is a visit or inspection fee and how it is treated if repair work proceeds. Confirm the details for your location and request.
Parts and labour
If a replacement is recommended, ask for the part identification, compatibility, fitting cost and applicable warranty terms. Similar symptoms do not always need the same repair.
The complete proposal
Understand what the agreed cost includes and how any additional work would be discussed. Keep the documentation provided for the completed service.
Avoid a diagnosis by price
An online estimate cannot establish the fault in your appliance. The model and suitable inspection determine what work is appropriate.
