Keeping your aircon clean is important, especially in Singapore’s hot and humid weather. However, many homeowners still ask the same question:
“Should I service all my aircon units together, or just clean the one that looks dirty?”
To help you choose, here is an easy-to-read guide that explains the difference between full-system aircon servicing and single unit cleaning, along with which option gives better comfort and savings.
1. Humidity Makes Your Aircon Work Harder
What Is Full-System Aircon Servicing?
Full-system servicing means cleaning every aircon unit in your home, including the outdoor condenser.
In Singapore, this is recommended every 3–6 months.
Full-System Servicing Includes:
Cleaning all indoor fan coil units
Clearing all drainage pipes
Checking gas pressure
Inspecting the outdoor condenser
Testing airflow and cooling
Simply put: your whole aircon system gets checked and cleaned.
What Is Single Unit Aircon Cleaning?
On the other hand, single unit cleaning focuses on only one aircon unit.
Most people choose this when only one room is having problems.
Single Unit Cleaning Includes:
Basic fan coil cleaning
Washing filters
Flushing the drain pipe
In short: only one part of the system is cleaned.
Full-System vs Single Unit: Which Should You Choose?
Let’s compare both options so you can decide easily.
1. Cooling Performance
Full-System Servicing:
First of all, all rooms cool better at the same time. Every unit gets cleaned, so airflow improves and cooling becomes faster.
Single Unit Cleaning:
Meanwhile, only the cleaned unit works well. The rest may still feel warm or weak.
Winner: Full-System Servicing
2. Long-Term Savings
Full-System Servicing:
Because all aircon units are maintained together, the system lasts longer. This helps you avoid expensive repairs or frequent gas top-ups.
Single Unit Cleaning:
However, the other units may break down later, which leads to more costs.
Winner: Full-System Servicing
3. Preventing Mould, Smells & Leaks
Full-System Servicing:
In Singapore’s humid climate, mould and water leaks are common. When all units get cleaned, these problems are reduced because every drain pipe and coil is cleared.
Single Unit Cleaning:
In contrast, uncleaned units may still drip water or produce odours.
Winner: Full-System Servicing
4. Convenience
Full-System Servicing:
You only need one visit. This is easier and faster for busy families.
Single Unit Cleaning:
On the other hand, you may need more visits later if other units start having problems.
Winner: Full-System Servicing
When Is Single Unit Cleaning Enough?
Single unit cleaning is okay if:
Only one room has issues
You rarely use the other units
You need a quick fix
You want the cheapest option for now
Still, doing full-system servicing at least once a year is important.
So… What’s Better?
Overall, Full-System Aircon Servicing is the better choice for most Singapore homes. It gives you:
✔ Better cooling
✔ Lower electricity bills
✔ Fewer breakdowns
✔ Cleaner air
✔ Longer lifespan for your whole system
Single unit cleaning is only good for simple or temporary problems.
