What aircon repair involves
A technician diagnoses why your unit is warm, noisy, leaking or not starting, then fixes it. Common jobs in Subang Jaya homes include gas (refrigerant) top-ups after a leak, replacing a faulty capacitor or fan motor, clearing a blocked drain line, and swapping a failed PCB or sensor. Most calls involve wall-mounted split units, though some contractors also handle ceiling cassettes and multi-split systems.
What to look for
- A clear diagnosis before work starts, with the fault named and the part quoted.
- Leak testing, not just a gas top-up that will run out again.
- Experience with your brand and inverter or non-inverter model.
- A written warranty on parts and labour.
- Reasonable response time, since a dead unit in this heat is urgent.
