Clear information before work starts

Start with the symptom, then confirm the right fix

Singapore's heat and humidity bring the same problems again and again: water leaking indoors, mould and musty smells, weak cooling and units that overheat. Share the brand, how many units and what you are seeing, including any blinking light or error code, so the technician arrives with the right context.

Describe the aircon issue

Send photos or a short video through WhatsApp, including any error code or blinking pattern, or speak directly with the service team. Final diagnosis and scope depend on the unit and site conditions.

Homes & commercial

A practical service process

Aircon work should begin with the right diagnosis

A leak or a blinking light is a symptom, not a cause. Checking the filters, drain line, coil, refrigerant and error code first avoids paying for parts or a chemical wash the unit does not need.

Describe

Share the brand, unit type, number of units and the symptom or error code.

Inspect

Check filters, drain pan and pipe, coil condition, refrigerant level and the electrical supply.

Confirm scope

Explain the likely cause and agree whether servicing, a chemical wash, gas top-up or repair is needed.

Test and hand over

Carry out the work, then run the unit to confirm cooling and drainage before handover.

Servicing and installation

General servicing, chemical wash, overhaul, gas top-up and new units are listed in the complete service directory.

Faults and leaks

Water leaking, blinking lights, weak cooling and compressor faults are covered under repairs and troubleshooting.

Aircon rules in Singapore

NEA requires approved refrigerants and proper disposal of coolants during servicing and repair. In HDB flats, aircon installation must follow HDB guidelines on mounting location and secure fittings, and noise must be kept within acceptable limits for neighbours.
