Typical scenarios within this site’s subject: questions to ask, materials to prepare and points that can be examined.
Typical scenarios
Suppose a repair record names one gas component, while an accessible equipment marking shows another model. The question is whether the discrepancy concerns the paperwork or the work actually performed.
Typical scenarios
If one heating riser warms up after work while the adjacent one remains noticeably cooler, a general statement that the system works may be insufficient. Analysis would need to connect the complaint to particular rooms, system sections and operating conditions at the time, rather than compare photographs taken on different days.
