“Diagnose why a residential HVAC system is making unusual grinding noises and determine if it needs immediate repair”
Summary · Diagnose the source of grinding noises in a residential HVAC system and assess whether immediate repair is required.
HVAC diagnosis requires physical inspection, hands-on testing with specialized tools, and sensory assessment (listening, feeling vibrations, checking temperatures). AI can provide troubleshooting guides or common causes, but cannot perform the actual diagnostic work which involves physical presence and tactile/auditory expertise. This is fundamentally a skilled trade requiring on-site work.
