AC Warranty Claim Process — Coverage / Exclusions / Evidence
Likely causes
Warranty period + free coverage + exclusions
Check: **Korean standard warranty**: full unit 1 yr, compressor 5–10 yr, installation 1 yr (by installer), parts 5 yr (manufacturer). LG/Samsung/Carrier = +1–2 yr on cloud registration. **Free coverage**: refrigerant leaks (install/factory defect), compressor failure, inverter PCB failure, sensor failure, poor workmanship (installer's responsibility). **Exclusions**: ① consumer fault (impact/damage/flood). ② abnormal install environment (unstable power/humidity/temperature). ③ non-OEM parts or private repair traces. ④ warranty expired. ⑤ **no purchase receipt**. ⑥ DIY/modification traces.
What to do: **Claim procedure**: 1) User contacts manufacturer (Samsung 1588-3366, LG 1544-7777). 2) Service visit = free in cities, KRW 10–30k in outlying. 3) **Required evidence**: purchase receipt, install report, maintenance log, photos. 4) Free decision = parts and labor free. Paid decision = quote then customer consent. 5) **Installer-side defects** (leaks/comm within 1 yr) = installer handles free directly. 6) **In disputes** = Korean Consumer Agency mediation per Consumer Dispute Resolution Standard. Install report = advantage. **R-Pro = automatic report and history = 95% dispute prevention**.
**Field trick**: warranty claims need receipt/install report = 100% acceptance. If user lost them, card statements/order emails also help. **Installers without reports** carry heavy burden for 1-year defects. R-Pro users = automatic report/photos/measurements gives overwhelming advantage in disputes. **2025 new = AI-based diagnostic systems** (users self-diagnose via app then auto-schedule). New R-32 systems = warranty 2–3+ years (manufacturer marketing).
