The Problem
A legal firm occupying a 3,200-sqft office suite at Menara Prestige near KLCC was tired of dealing with aircond breakdowns. In the past 12 months alone, they had called 3 different technicians for emergency repairs — a leaking ceiling cassette that damaged legal documents, a wall unit that stopped cooling during a client meeting, and a compressor failure that left the server room overheating.
Each incident cost RM200–500 in emergency call-out fees plus repair charges. The office manager realised they were spending more on reactive repairs than they would on preventive maintenance. She contacted Masters Aircond Service KL to discuss a maintenance contract for their 8 Daikin units.
Our Assessment
We conducted a comprehensive audit of all 8 units before proposing a maintenance plan:
- 4 Daikin FTKF wall-mounted units (1.5HP each) — serving partner offices and the conference room. 2 units had dirty filters, 1 had a slow drain leak
- 3 Daikin FCC ceiling cassettes (2.5HP each) — serving the open-plan paralegal area and reception. All showed moderate coil contamination
- 1 Daikin FTKF wall-mounted unit (2.0HP) — dedicated to the server room, running 24/7. This unit was in the worst condition with heavy dust buildup and early signs of ice formation on the evaporator
- Overall — no units had been serviced in over 8 months. None had any critical mechanical faults, but continued neglect would lead to more breakdowns
We proposed an annual maintenance contract: 4 quarterly servicing visits covering all 8 units, with priority emergency response included at no extra call-out fee.
Work Timeline
Step 1: Initial Deep Service (Visit 1)
First visit was a thorough deep service of all 8 units — filter cleaning, coil cleaning, drain flushing, and blower cleaning. The server room unit received extra attention, including a chemical spot-clean on the evaporator to remove ice-causing buildup.
Step 2: Drainage Repair
Fixed the slow drain leak on the conference room unit — a loose drain hose coupling was tightened and sealed with PVC adhesive. Tested with water to confirm no more dripping.
Step 3: Performance Baseline
Recorded baseline temperature and pressure readings for all 8 units. This data serves as a reference for future visits — any deviation indicates developing issues before they become failures.
Step 4: Maintenance Schedule Setup
Set up a quarterly schedule: January, April, July, and October — always on Saturday mornings to avoid disrupting office operations. Each visit is confirmed via WhatsApp 1 week in advance.
Step 5: Service Report & Documentation
Delivered a detailed service report with photos documenting the condition of each unit, work performed, and recommendations. Reports are provided after every quarterly visit for the office manager's records.

Lessons & Advice
For offices with 5 or more aircond units, a maintenance contract is almost always more cost-effective than ad-hoc servicing. Here's the math: the legal firm was spending roughly RM3,500–4,000/year on emergency call-outs and one-off servicing. Their annual contract with Masters Aircond Service KL costs RM2,880/year — and includes priority emergency response with no call-out fee.
Beyond cost savings, the real value is zero downtime. A law firm can't afford a conference room that's 32°C during a client meeting, or a server room that overheats and crashes their case management system. Preventive maintenance catches problems early — a dirty coil today becomes an iced-up evaporator next month and a compressor failure the month after.
Our maintenance contracts at Masters Aircond Service KL cover quarterly servicing with full documentation. For offices that want deeper cleaning, we can add an annual chemical wash to the contract at a discounted rate. Contact us for a customised quote based on your unit count and type.
