The Customer's Situation
Encik Rizal hired a Facebook contractor to install four new Panasonic units in his USJ semi-D. Three units worked fine, but the master bedroom 2.0HP never felt properly cold — hovering at 26-27°C even set to 22°C. The original installer dismissed concerns twice, saying "it's normal." After reading our blog on common installation mistakes, Encik Rizal called us.
Our Diagnosis
Technician Wan found 18°C outlet air (should be 12-13°C for this model). A cracked flare fitting was leaking gas, and the system showed moisture contamination from improper vacuuming. The original installer's shortcuts were the sole cause of the poor performance.
Results
- Outlet temperature: 18°C → 12°C
- Room cooling: 45+ min to 26°C → 18 min to 24°C
- Gas leak permanently fixed
- Moisture contamination eliminated

Customer Feedback
"The original installer kept saying the unit was fine. Wan found the problems in 15 minutes — cracked flare and no proper vacuum. After the fix, the bedroom finally feels cold. I wish I had called Total Aircond first instead of going with the cheapest Facebook quote."
