General aircon servicing cost
Routine maintenance — cleaning filters, blower, and evaporator, flushing the drainage tray, and checking refrigerant pressure. Priced per unit, with cheaper rates for recurring packages.
| Units | One Time | Twice Yearly | Thrice Yearly | Quarterly |
|---|---|---|---|---|
| 1 | $45 | $85 | $125 | $165 |
| 2 | $60 | $115 | $175 | $225 |
| 3 | $75 | $145 | $215 | $280 |
| 4 | $90 | $175 | $260 | $345 |
| 5 | $105 | $205 | $305 | $405 |
| 6 | $120 | $235 | $350 | $465 |
Twice / thrice / quarterly columns are the total annual price for that many visits. Six units on a quarterly plan works out to roughly $20 per unit per visit.
Chemical wash & chemical overhaul cost
Deeper cleans for units that smell, drip, or cool poorly despite regular servicing. A wash cleans in place; an overhaul dismantles the unit for the deepest clean.

Gas top-up & condenser cleaning cost

What affects the cost of aircon servicing?
Number of units
Price is charged per indoor unit, but the per-unit rate drops as you add units — a 6-unit service costs far less per unit than a single unit.
One-time vs recurring package
A recurring quarterly or tri-annual contract lowers the per-visit price significantly versus booking each visit one-off.
Service depth
Routine servicing is the cheapest. A chemical wash (deeper clean) and chemical overhaul (full disassembly) cost more because they reach dirt that filter-level cleaning cannot.
Unit type & BTU
Larger units (18,000–24,000 BTU), ceiling cassettes, and ducted systems take longer and cost more than standard wall-mounted units.
Condition & history
A unit neglected for years may need an overhaul rather than a wash, and a gas top-up if refrigerant has leaked — both add to the bill.
How to keep your servicing cost down
- Service regularly (every 3–4 months) so dirt never builds up enough to need an expensive chemical wash or overhaul.
- Bundle multiple units in one visit — the per-unit price falls sharply with more units.
- Take a recurring package (twice, thrice, or quarterly yearly) instead of paying one-off rates each time.
- Fix small issues early — a $45 service is far cheaper than a compressor or motor replacement later.
What we never charge
- ✓ No hidden fees — the price we quote is the price you pay
- ✓ No call-out or out-of-area surcharge — same price island-wide
- ✓ No upselling — we recommend the lightest service that fixes the problem
