General aircon service
Air conditioners are essential in Singapore’s hot and humid climate, and the fan coil unit plays a vital role in delivering cool air inside your home or office. However, many people forget that regular maintenance is necessary to keep the system efficient. One of the most common questions homeowners ask is: How often should I perform aircon general servicing for my fan coil?
Regular aircon servicing Singapore helps prevent common issues such as aircon not cold, aircon water leaking, and even system faults like aircon light blinking or an aircon error code. In this guide, Letscool Aircon and Services Singapore explains the recommended servicing schedule and why routine maintenance is important.
Why Fan Coil Servicing Is Important
The fan coil unit is responsible for circulating cool air throughout your room. Over time, dust, dirt, and moisture accumulate inside the unit. If not cleaned regularly, this buildup can reduce cooling efficiency and cause system problems.
Regular aircon general servicing ensures that the internal components remain clean and functional. Professional technicians will clean filters, inspect coils, check drainage systems, and ensure the unit operates smoothly.
Without proper maintenance, you may face issues like:
-
Weak airflow
-
Bad odors from the aircon
-
Aircon not cold
-
Increased electricity bills
Scheduling routine aircon servicing in Singapore helps maintain comfort while extending the lifespan of your air conditioning system.

Recommended Servicing Frequency for Fan Coil Units
So, how often should you service your fan coil unit? The answer depends on usage.
Typical servicing schedule:
-
Residential homes: Every 3–4 months
-
Heavy usage homes: Every 2–3 months
-
Offices or commercial spaces: Every 1–2 months
Frequent servicing ensures dust and mould do not accumulate inside the unit. Many homeowners in Singapore sign up for an aircon service contract to ensure regular maintenance without forgetting the schedule.
With a reliable aircon service contract, professional technicians from Letscool Aircon and Services Singapore can inspect and maintain your system regularly.
Signs Your Fan Coil Needs Immediate Servicing
Even if you follow a regular servicing schedule, sometimes your air conditioner may require immediate attention.
Here are common warning signs:
-
Aircon not cold even when set at low temperatures
-
Aircon water is leaking from the indoor unit
-
The aircon light is blinking unexpectedly
-
An aircon error code appears on the display
-
Strange noises from the fan coil
When these problems occur, it is best to contact professionals for aircon repair in Singapore. Early detection prevents further damage and avoids costly replacements.
In some cases, technicians may need to replace worn aircon spare parts or perform aircon compressor servicing to restore proper cooling.
When Is a Chemical Wash or Steam Wash Needed?
While aircon general servicing handles basic cleaning, deeper cleaning methods are sometimes required.
If your fan coil unit has excessive dirt buildup or mould growth, technicians may recommend:
Aircon Chemical Wash
This process removes stubborn dirt, bacteria, and clogged debris from internal components.
Aircon Steam Wash
An eco-friendly cleaning method that uses high-temperature steam to eliminate bacteria and dust.
Aircon Chemical Overhaul
A more intensive cleaning process where the unit is dismantled for deep cleaning and inspection.
These procedures are commonly recommended when problems such as aircon water leakage or weak cooling persist despite regular servicing.
The Role of Gas Top-Up and Compressor Servicing
Sometimes, poor cooling performance is not related to dirt but to refrigerant levels. When the refrigerant drops, the air conditioner cannot cool efficiently.
In such cases, technicians may perform an aircon gas top-up to restore proper cooling capacity.
Additionally, the outdoor unit compressor plays a critical role in the cooling cycle. If cooling issues continue, aircon compressor servicing may be required to ensure the compressor operates properly.
Regular aircon servicing in Singapore allows technicians to detect these issues early before they lead to major repairs.
