The Customer's Situation

Puan Lim Mei Ling runs an accounting firm in TTDI. Her 14-year-old Daikin ceiling concealed unit had been leaking for 3 months. Three different technicians cleared the drain — each time it worked for 2 weeks then leaked again. Staff were using plastic sheets on desks to protect computers.

Real Problem Found

  • Galvanised steel drain pan cracked with multiple hairline fractures along seams
  • Water seeping through cracks, bypassing drain entirely
  • Previous technicians only cleared the drain — never inspected the pan
  • Evaporator coil corroding on bottom fin rows
  • Blower motor running at reduced speed

Our technician Ravi opened up the concealed unit and inspected what others hadn't — the drain pan itself. The cracks were invisible from outside. Water leaked through the pan, not from overflow. That's why drain clearing never worked.

Work Completed

  • Removed 14-year-old Daikin ceiling FCU
  • Installed new compatible Daikin ceiling concealed FCU
  • Connected to existing refrigerant piping with pressure test and vacuum
  • Verified drain drainage with water test
  • Replaced water-damaged ceiling panel section
  • Full commissioning and 1-hour run test

We kept the working outdoor unit — saving RM2,000-3,000 vs full system replacement. Understanding when to replace an FCU and why airconds leak is key to cost-effective decisions.

Pricing

  • New Daikin FCU: RM1,200
  • Removal + installation: RM400
  • Pressure test + vacuum + gas: RM120
  • Ceiling panel: RM80
  • Total: RM1,800

Customer Feedback

"After 3 failed repairs by other companies, Total Aircond found the real problem in 15 minutes — cracked drain pan. The new unit is quieter and colder. My staff finally work without plastic sheets! Should have called them first."
