Frequently Asked Questions

How often should I service my Mitsubishi aircon? expand_more

For typical Singapore households, we recommend every 3-4 months. For offices or rooms with heavy usage, every 2 months is ideal to maintain efficiency.

What is included in the $42 basic servicing? expand_more

It includes cleaning filters, vacuuming the evaporator coil, flushing the drainage pipe, and a system health check. Minimum of 2 units required.

Why is my Mitsubishi Starmex light blinking? expand_more

A blinking light indicates a safety shut-off due to a fault code. It could be anything from a sensor failure (P1/P2) to a drainage issue (P5).

Do you provide a warranty for repairs? expand_more

Yes, all our repair work and parts come with a 90-day workmanship warranty.
