Servicing & maintenance

Which service type fits your unit?

The right service depends on contamination level, airflow condition, smell, drainage behavior, and how long the unit has gone without proper cleaning. We do not push a chemical overhaul when a normal service is enough. For most homes, the decision is between three levels:

• *General servicing: routine maintenance for units that are cooling normally and serviced on schedule
• *Chemical wash: deeper cleaning for weak airflow, musty smell, or heavy dirt buildup
• *Chemical overhaul: full teardown clean for severe contamination, persistent mould, or neglected units
• *If the unit is not cold due to an electrical or refrigerant fault, servicing alone may not solve it

General servicing (routine maintenance)

This is the standard maintenance visit for units that are still cooling and draining normally. It keeps the system clean enough to maintain airflow and reduces the chance of avoidable breakdowns. Suitable for homes already on a regular servicing schedule.

• *Filter removed, washed, and dried
• *Evaporator coil rinsed
• *Drain pan and drain line cleared
• *Blower fan inspected
• *Cooling and drainage tested
• *Best for units serviced regularly (typically every 3 to 4 months)

Chemical wash (deeper cleaning without full teardown)

A chemical wash is for units with heavier dirt buildup, biofilm, or smell that a normal service will not clear well. It is commonly recommended when airflow has dropped, cooling feels weaker, or the indoor unit smells musty even after routine cleaning.

• *Evaporator coil soaked and flushed with chemical solution
• *Drain pan cleaned and sterilised
• *Blower fan cleaned in place
• *Filter deep-cleaned
• *Full drainage and cooling test
• *Common signs: weak airflow, persistent smell, overdue servicing (6+ months), recurring minor drain issues

Chemical overhaul (full disassembly cleaning)

A chemical overhaul is a full teardown clean of the indoor unit. It is usually reserved for severe contamination, long-neglected units, or cases where mould and sludge buildup is too heavy for in-place cleaning. This is not the first recommendation unless the condition clearly calls for it.

• *Indoor unit fully disassembled
• *Coil, blower, and drain pan removed and soaked
• *All components cleaned and dried individually
• *Unit reassembled and leak-tested
• *Full drainage and cooling performance test
• *Typical use cases: heavy mould contamination, years without thorough cleaning, recurring blockage from deep buildup

What servicing can fix — and what may need repair instead

Servicing helps when cooling performance drops because airflow is restricted, the coil is dirty, or drainage is partially blocked. It does not fix every 'not cold' complaint. If the unit has a refrigerant leak, faulty capacitor, fan motor issue, PCB fault, or sensor problem, that becomes a diagnostic/repair job.

• *Usually improved by servicing: dirty filters, coil contamination, mild drain blockage, odour from buildup
• *Often not fixed by servicing alone: refrigerant (gas) leaks, compressor faults, electrical faults, control board failures
• *If we spot a repair issue during servicing, we explain it before doing anything else

How often should you service your aircon?

There is no single interval that fits every home. Usage hours, pets, renovation dust, smoking, cooking load, and room environment all affect buildup rate. As a rough guide for Singapore homes:

• *Heavy use (daily/nightly): every 3 to 4 months
• *Moderate use: every 4 to 6 months
• *Light use / spare rooms: every 6 months (or based on condition)
• *Post-renovation or dusty environments may need earlier deep cleaning

What affects the servicing quote and scope

Servicing prices depend on more than just the number of units. Unit type, access conditions, contamination level, and the service level required all affect time and scope. We confirm the right service after understanding the condition and symptoms.

• *Number of indoor units and system layout (single split / multi-split)
• *Unit type (wall-mounted, cassette, ducted/FCU access)
• *General service vs chemical wash vs chemical overhaul
• *Access difficulty and site constraints
• *Whether there are active issues (leak, not cold, noise) that may require diagnosis

What we check on every servicing visit

Regardless of service type, we check the same failure-prone areas and flag anything that looks off before it becomes a bigger repair bill.

• *Drainage flow — blocked drains are the most common cause of leaks
• *Coil condition — heavy contamination reduces cooling efficiency
• *Refrigerant (gas) behaviour — signs of undercharge or loss
• *Electrical connections — loose wiring is a fire and fault risk
• *Filter condition — a clogged filter strains the blower motor
