AC Commissioning Report / Handover — Standard Form + Photos / Measurements
Likely causes
Standard form + 8 measurements + 7 photos mandatory
Check: **Report standard items**: 1) Customer info (name/address/phone). 2) Product info (model/serial/year/refrigerant). 3) Install info (line length/height diff/outdoor location). 4) **8 measurements**: suction & discharge pressure, superheat, subcooling, indoor return temp, indoor supply temp, run current, voltage. 5) **7 mandatory photos**: outdoor exterior, outdoor nameplate, indoor exterior, indoor nameplate, manifold gauge (during commissioning), vacuum gauge, comm/power wiring. 6) Commissioning duration (≥30 min). 7) Tech and customer signatures. Korea = 4-page standard.
What to do: **Procedure**: 1) Pre-test = 4 photos (exterior/nameplates). 2) During test = 8 measurements + 2 photos (gauges). 3) Post-test = 1 photo (wiring) + consistency check. 4) Write in Korean (with bilingual EN/ZH for foreign customers). 5) PDF + upload to R-Pro app or cloud. 6) One paper copy to customer (magnet on outdoor unit). 7) Tech keeps 1 copy (5 years required). **In disputes** = report/photos = installation evidence.
**Field trick**: report with photos and measurements prevents 95% of disputes. If user claims poor workmanship = tech's safety net. **Defects appearing 1 year later** = report clarifies user vs tech responsibility. R-Pro app = automated report form + cloud backup + customer notification all built-in. **5-year retention required** (Korean Framework Act on Consumers) = losing it risks losing legal cases. No report = sign of 30%-priced unskilled work.
