Performed diagnostic assessment on non-functional 1.5-year-old Lennox mini-split system and determined the system is completely depleted of refrigerant charge, explaining the no heat/cool complaint. Visual inspection of both indoor wall-mounted unit and outdoor condenser revealed no obvious external damage, but system requires leak detection and subsequent refrigerant system repairs to restore operation. Discussed findings with homeowners and recommended follow-up with service advisor to review repair options.
