Aircon servicing in Singapore has a huge quality variance at similar price points. A proper quarterly service takes 20-30 minutes per unit and includes filter washing, blower fan cleaning, drain-pipe flushing, and gas pressure check — shortcut services that skip these produce breakdowns within 2-3 years.

Quarterly servicing is the Singapore standard — our tropical humidity accumulates mould, dust, and bacteria faster than temperate climates. Units that go 6+ months without servicing develop cooling loss, water leaks, and musty smells that require chemical wash (S\$80-180) to fully clean. Quarterly contracts at S\$25-50 per unit work out significantly cheaper than reactive one-off bookings.
General service (S\$25-50/unit) is surface cleaning and inspection. Chemical wash (S\$80-180/unit) sprays the evaporator coil with cleaning chemicals to remove build-up. Chemical overhaul (S\$150-320/unit) dismantles the unit, soaks components in chemical solution, and reassembles — typically needed every 3-5 years depending on usage.
A legitimate technician uses pressure gauges to verify gas levels before recommending a top-up (S\$80-160 per unit). Non-cooling is more often caused by dirty coils (needing chemical wash), clogged drainage, or a failing compressor — not low gas. Technicians who insist on gas top-up without testing are selling you gas you don't need.
Yes, for most households with 3+ aircon units. Quarterly contracts include 4 general services per year per unit at 15-25% discount over one-off pricing. For HDB properties with regular use (most homes in Yishun), contracts also include priority emergency response and free minor fixes. One-off bookings suit vacation homes or infrequent-use units.
Those rates don't cover a proper 20-30 minute service — they indicate a superficial clean (wipe-down of filters, spray of dust). Genuine servicing requires tools, chemicals, drainage clearing, and pressure testing. Low-cost "services" cause premature unit failure — expensive repairs within 2-3 years cost more than proper service would have.
