Aircon Servicing
In a tropical climate like Singapore, your air conditioner isn't just a luxury—it's a necessity. However, like any electrical appliance, aircons are prone to wear and tear, especially when used frequently. Ignoring early warning signs can lead to costly repairs or even complete system breakdowns. At LetsCool Aircon and Services, we often help customers who could have avoided major issues if their aircon had been serviced at the right time.
So, how do you know when your aircon needs immediate attention? Below are the key warning signs that should never be ignored. View more.
1. Weak or No Cool Airflow
If your air conditioner is running but not blowing cold air—or the airflow feels weak—this is one of the most obvious signs something is wrong. It could indicate:
A clogged air filter

A refrigerant leak

A malfunctioning compressor or fan motor

Immediate servicing by a qualified technician from LetsCool Aircon can restore your unit’s cooling efficiency and prevent further damage.
2. Unusual Noises
While all air conditioners ...
... make some noise, any unusual sounds like rattling, grinding, buzzing, or screeching are red flags. These noises may be due to:
Loose components

Worn-out fan belts

Motor issues

Internal debris or obstructions

Early intervention by our team can prevent minor faults from escalating into major mechanical failures.
3. Bad Odours Coming from the Unit
If your aircon emits foul or musty smells, it could mean mould or mildew has built up inside the system—typically due to trapped moisture or a dirty filter. This not only affects indoor air quality but also poses health risks.
LetsCool Aircon offers comprehensive cleaning and chemical wash services to eliminate bacterial growth and keep your home or office air healthy and fresh.
4. Frequent On and Off Cycling
Does your air conditioner turn on and off repeatedly within a short period? This is known as short cycling and may be caused by:
A dirty condenser or evaporator coil

A faulty thermostat

Electrical issues

Our experienced technicians can quickly diagnose and resolve the root cause, ensuring your unit operates smoothly.
5. Water Leaks or Ice Buildup
A well-functioning air conditioner should never leak water or form ice around its components. Leaking water could point to:
A clogged drainage pipe

A cracked drain pan

Faulty insulation or improper installation

On the other hand, ice buildup may result from low refrigerant levels or restricted airflow. Both issues require urgent servicing to prevent further complications.
6. Spiking Electricity Bills
A sudden and unexplained increase in your electricity bill can be linked to an inefficient aircon unit. When filters are clogged or internal parts are malfunctioning, your system works harder than necessary—consuming more energy.
Regular maintenance by LetsCool Aircon and Services ensures your system runs efficiently, saving you money in the long run.
7. Inconsistent Room Temperatures
If certain areas in your home or office are significantly colder (or warmer) than others, your aircon may have:
A malfunctioning thermostat

Damaged ducts

Blocked vents

Our team at LetsCool can inspect and balance your cooling system to ensure consistent airflow across all rooms.
8. Unresponsive Controls or Remote
If the unit doesn't respond to remote commands or switches off unexpectedly, it could be due to:
Faulty circuit boards

Sensor issues

Remote control malfunctions

Delaying service in such cases can lead to a complete system failure. Our technicians are skilled in diagnosing electronic issues across all major brands, including Daikin, Mitsubishi, Panasonic, and more.
Why Immediate Servicing Matters
Delaying aircon servicing can lead to:
Higher repair costs

Shortened equipment lifespan

Poor indoor air quality

Uncomfortable living conditions

At LetsCool Aircon and Services, we recommend getting your aircon checked every 3 to 6 months, especially in Singapore’s humid climate where units operate nearly year-round.
