Recommended Servicing Schedule for Singapore Homes
1. HDB Homes
HDB flats tend to gather dust faster, especially when windows are opened daily.
| Number of Aircon Unit | 1 Time Service |
|---|---|
| Usage Level | Recommended Servicing |
| Daily (6–10 hrs/day) | Every 2 months |
| Moderate (3–6 hrs/day) | Every 3 months |
| Light (1–3 hrs/day) | Every 4–6 months |
For deeper cleaning, a chemical wash every 6–12 months works best.
2. Condominium Units
Condos often have better ventilation, but servicing is still crucial.
| Usage Level | Recommended Servicing |
|---|---|
| Heavy daily use | Every 2–3 months |
| Moderate use | Every 3–4 months |
| Light use | Every 4–6 months |
Condo trunking is often concealed — making early leak detection more important.
3. Landed Properties
Larger floor space means aircons work harder.
| Aircon Type | Frequency |
|---|---|
| Multi-split units | Every 2 months |
| Central aircon systems | Every 1–2 months |
| Guest room units | Every 6 months |
Because landed homes face higher dust and outdoor moisture, consider aircon troubleshooting if you notice any sudden drop in cooling.
⚠️ Signs Your Aircon Needs More Frequent Servicing
You should increase servicing frequency if you notice:
Weaker airflow
Not cold even at low temperature
Water leaking from indoor unit
Moldy or musty smell
Louder noise than usual
Higher electricity bills
If these symptoms appear, a deeper chemical overhaul may be required.
🏢 How About Commercial Properties?
Commercial spaces like gyms, offices, clinics and F&B outlets run aircons for long hours.
Recommended servicing:
- Monthly servicing for high-usage environments
- Chemical wash every 6 months
Breakdowns during operating hours can affect business continuity — so proactive maintenance is key.
💡 Tips to Reduce Unnecessary Wear and Tear
You can prolong your aircon’s lifespan with simple habits:
- Clean filters twice a month
- Set temperature between 24°C–25°C
- Keep doors & windows closed
- Avoid blocking vents
- Don’t overuse turbo mode
- Ensure proper gas top-up when needed
Frequently Asked Questions (FAQ)
For light users, quarterly is acceptable, but households using aircon daily should service every 2–3 months.
No — chemical wash is recommended only every 6–12 months or when the unit is very dirty.
If you experience leaks, weak cooling, or unusual noises, basic servicing may not be enough — you should book a troubleshooting session.
Skipping servicing leads to higher electrical bills, poor cooling, faster wear and tear, and a higher chance of major breakdowns.
📌 Final Recommendation: How Often Should You Service?
For most Singaporean households, the ideal servicing interval is every 2–3 months, with a deeper chemical wash every 6–12 months depending on usage. If your aircon shows signs like reduced cooling, unusual noises, higher electricity bills, or water leaks, it’s best to schedule troubleshooting immediately rather than wait for the next servicing cycle. A proper maintenance routine helps your aircon deliver colder air, consume less energy, and last significantly longer, ensuring a more comfortable home environment throughout the year.
