Today, 20 November 2014, we replaced our defective 13-year-old aircon with the new Mitsubishi Starmex System.
Update 5 October 2017: It’s still working smoothly and silently, though we never serviced it for a long time.
We chose this model because Jack Neo demonstrated on TV the easy self-cleaning maintenance.
In this post, I document the little lessons learnt from this experience of aircon installation.
Limited Time Promo Deal:
- Mitsubishi Inverter Multi Split AirCon – System 2 / 3 / 4 [Available in : 2 and 5 Ticks]
Lesson #1: Installing on weekdays is recommended over weekends to avoid complaints from neighbours.
Lesson #2: Using back existing pipes and trunking does not include them in the overall warranty.
Lesson #3: Test gas pipe leakage by releasing gas at the compressor and if gas rushes out, the pipe is good.
Lesson #4: Test condition of existing electrical wiring by turning each unit on and off individually.
Lesson #5: There are two pipes from each aircon unit. One a gas inlet and one water outlet.
Lesson #6: Installation of water outlet pipes must angle downwards for water to flow all the way out.
Lesson #7: Thicker insulator reduces chances of condensation, but costs S$60 more per room.
Lesson #8: Finally, remember to vacuum suck the water outlet to flush clean it during servicing.

Update (December 2015):
After using Mitsubishi Starmex for a year, here’s my updated review.
- The silent mode is truly quiet. I use this mode most of the time.
- The compressor is still clean. Even the maintenance men say it need not be cleaned.
- It looks bulky, ugly and not very sleek, but it’s worth it.
