They take longer and may need ceiling access, so we price them after seeing the setup.

Yes. Contract servicing is $25 per unit per visit.

Every 3 months for daily use, which is common in Singapore. If you only use it at night, every 4 to 6 months is fine.

All major brands, including Daikin, Mitsubishi Electric, Panasonic, LG, Samsung, Midea, Toshiba and Fujitsu.

A chemical wash cleans the coil and blower while the unit stays on the wall. An overhaul takes the unit down and strips it completely, which is best for very dirty or smelly units.

About once a year for daily use, or whenever a smell or leak keeps coming back.

No. We use cleaners made for aircon coils and rinse them off fully.

Yes, including cassette and ducted units in condos and landed homes.

A check starts from $50. We tell you upfront whether it is offset if you go ahead with the repair.

Most leak, gas, drainage and capacitor faults are fixed on the spot. A PCB or compressor may need a second visit.

If the unit is over 10 years old and needs a compressor or another major part, a new inverter system often costs less over a few years. We give you both options.

Yes, 30 days on workmanship, plus the manufacturer's warranty on new parts.

Weak cooling, ice on the pipes and a constantly running compressor are common signs. We confirm with a pressure test before topping up.

No. The system is sealed, so low gas means a leak. We check for it so the problem does not return.

Most newer systems use R32 or R410A; older ones use R22. It is printed on the outdoor unit label.

R22 is an older refrigerant being phased out, so it is scarcer. Units that still use it are usually due for replacement.

A typical HDB System 3 or 4 is installed in one day. Replacements with new piping can take 1 to 2 days.

Yes. We follow HDB's requirements for the aircon ledge and piping routes.

Sometimes. We test it during the survey. New piping is recommended when switching gas types or when pipes are corroded.

Most 3-room flats use System 2 or 3, 4-room flats System 3 or 4, and 5-room flats System 4 or 5. We confirm after measuring the rooms.

The usual causes are dirty filters or coil, low gas, or a faulty outdoor fan or capacitor. A technician check pinpoints which.

It depends on the schedule. WhatsApp us early in the day for the best chance of a same-day slot.

Checks start from $50. Servicing or a gas top-up fixes many cases; we quote before any repair.

Water near wiring can be, so switch the unit off until it is checked.

A partly choked drain overflows only when the unit runs long hours and produces more water.

Often yes. WhatsApp us early with a photo.

You can pay per visit or upfront for the year. Ask us for the options.

Yes. Contract customers get a reduced rate on chemical washes.
