Repair work should begin with a structured diagnosis rather than an assumption about the cause: document control indications and operating conditions, check drainage and condensate routing, inspect outdoor-unit airflow and weather exposure, and assess electrical protection before testing components. Any work affecting a designated heritage asset should be considered against the relevant statutory and character-preservation requirements.
