Complete Guide to Aircon Servicing in Singapore (2025)
Everything you need to know about aircon servicing in Singapore - frequency, costs, what's included, and how to avoid being overcharged.
Singapore's tropical climate means your aircon works hard year-round. Regular servicing isn't just about comfort—it's about efficiency, longevity, and avoiding expensive repairs.
Types of Aircon Servicing
1. General Servicing (Basic Cleaning)
What's included:
- Filter cleaning/washing
- Outdoor condenser cleaning
- Drainage pipe flushing
- General inspection
Frequency: Every 3-4 months Cost: $25-40 per unit (cheaper in bundles)
2. Chemical Wash
What's included:
- Everything in general servicing
- Chemical cleaning of evaporator coils
- Fan blower cleaning
- More thorough drainage cleaning
When you need it:
- Water leaking from unit

Cost: $80-150 per unit
3. Chemical Overhaul

4. Gas Top-Up
Important: Gas doesn't "run out" naturally. If you need frequent top-ups, you have a leak.
| Gas Type | Typical Cost | Notes |
|---|---|---|
| R22 (older units) | $60-120 | Being phased out |
| R410A/R32 (newer) | $80-150 | More environmentally friendly |
Price Comparison by Units
| Service | 1 Unit | 2 Units | 3 Units | 4 Units |
|---|---|---|---|---|
| General | $30-50 | $50-70 | $75-100 | $90-120 |
| Chemical Wash | $80-150 | $150-280 | $220-400 | $280-520 |
| Chemical Overhaul | $150-300 | $280-550 | $400-800 | $520-1000 |
Red Flags: How to Spot Overcharging
- "Your gas is low" without checking for leaks
- Recommending chemical overhaul when you just need general servicing
- Not itemizing costs - parts vs labor vs service
- Creating urgency - "Must fix today or unit will break"
- Prices significantly above market range
Recommended Servicing Schedule
| Situation | Frequency |
|---|---|
| Daily use (most Singapore homes) | Every 3 months |
| Occasional use | Every 4-6 months |
| Office/commercial | Every 2-3 months |
| After renovation | Immediate service |
DIY Maintenance Between Services
- Clean filters every 2 weeks (just rinse with water)
- Keep outdoor unit clear of debris
- Run the fan mode occasionally to dry out moisture
- Listen for unusual sounds - grinding, clicking, or rattling
