User Self-Check Card — 5 Steps Before Service Call
Likely causes
5 user self-check steps before call
Check: **5-step card (post next to indoor unit)**: ① Breaker ON (dedicated breaker, often off after season). ② Remote battery & mode (heating mode in summer common; not dry/fan). ③ Filter cleaning (every 3 mo; dust=30% airflow drop). ④ Outdoor airflow (leaves/birds/stuff blocking). ⑤ Setpoint (≤24°C + high fan). Call if still wrong.
What to do: Card format (A6 landscape, magnetic back): logo + 5 checkboxes + photo icons + 24h service number. Include free with installation. Offer ₩5,000 discount on trip fee if customer pre-checks ① to ⑤ (marketing incentive). Korea data: 30% of service calls resolved within these 5 steps.
Korean elderly users often 'can't see remote' → service call. Card text ≥14pt with icons. Print English/Chinese cards for multicultural homes/migrant areas. Card boosts trust and repeat business. Send SMS reminder 1 week post-install.
