Aircon repair

In a hot and humid place like Singapore, air conditioning is not a luxury — it’s a daily necessity. That’s why thousands of homeowners constantly search online when something feels wrong with their cooling system. From aircon not cold situations to strange noises and blinking lights, these problems usually appear at the worst possible time.

At Letscool Aircon and Services Singapore, we handle these issues every day. Below are the most common aircon problems homeowners Google, what causes them, and the right solution before the damage becomes expensive.

1. Aircon Not Cold — The #1 Complaint

Nothing frustrates homeowners more than turning on the unit and getting warm air.

• Midea Aircon Not Cold

• Daikin Aircon Not Cold

• Mitsubishi Aircon Not Cold

• Panasonic Aircon Not Cold

Common causes:

• Dirty filters and a clogged fan coil

• Low refrigerant (gas)

• Faulty thermostat sensor

• Compressor weakness

• Poor previous aircon installation in Singapore

When airflow is blocked, the system struggles to cool properly. Many people assume they only need an aircon gas top-up, but topping up gas without fixing leaks is only temporary.

Proper fix:

Start with aircon general servicing.
If cooling is still weak, technicians may recommend:

• aircon chemical wash

• aircon steam wash

• or full aircon compressor servicing

Ignoring this problem increases electricity bills and damages the compressor, the most expensive component to replace.

2. Aircon Water Leakage From Indoor Unit

Another very common Google search: water dripping from the aircon.

• Daikin Aircon water leaking

• Midea Aircon water leaking

• Mitsubishi Aircon Water Leaking

• Panasonic Aircon Water Leaking

Why does it happen:

• Choked drainage pipe

• Frozen evaporator coil

• Dirty fan coil unit

• Incorrect installation angle

• Cracked drainage tray

Water leaks are usually a maintenance issue rather than a hardware failure. Dust builds up over time and blocks drainage flow.

Solution:

Routine aircon servicing Singapore prevents this entirely.
If leakage continues, technicians perform:

• aircon chemical overhaul

• Replacement of worn aircon spare parts

This restores proper drainage and airflow.

3. Aircon Light Blinking — What Does It Mean?

Many modern systems warn users by flashing indicator lights. The problem is — homeowners rarely know what it means.

• Daikin Aircon Light blinking

• Mitsubishi aircon light blinking

• Midea aircon light blinking

• Panasonic Aircon Light blinking

Possible reasons:

• Sensor malfunction

• Fan motor failure

• PCB board issue

• Communication failure between the indoor & outdoor unit

Most of the time, blinking lights are linked to an aircon error code stored inside the unit.

What you should do:

Do NOT keep restarting the aircon repeatedly.
Call Aircon Repair Singapore to diagnose using professional tools. Continuing to run the unit can burn the motherboard.

4. Aircon Error Code Appearing on Display

When an error code appears, your aircon is basically telling you: stop using me and fix the problem.

Mitsubishi Aircon Error Code

Midea Aircon Error Code

Panasonic aircon error code

Typical error categories:

• E1/E2 – sensor faults

• EC – gas leakage

• F3 – compressor overload

• H6 – fan motor failure

Each brand has its own code system, but all require inspection.

Technicians from the best aircon servicing Singapore companies will:

• Identify the fault

• Replace faulty aircon spare parts

• Test full operation

A proper repair is cheaper than waiting until a total breakdown.

5. Strange Noise or Smell From Aircon

If your aircon sounds like grinding metal or smells musty, don’t ignore it.

Common reasons:

• Worn bearings

• Loose blower wheel

• Mould bacteria buildup

• Electrical burning

Mould is especially common in humid homes. Besides a bad smell, it affects indoor air quality.

Recommended service:

• aircon steam wash to remove bacteria

• aircon chemical wash for deep cleaning

• Scheduled aircon service contract

Routine maintenance keeps the air fresh and prevents health issues.

6. Aircon Suddenly Stops Working

Sometimes the unit just refuses to turn on — no airflow, no sound.

Possible causes:

• Capacitor failure

• PCB board fault

• Compressor trip

• Power supply issue

If your system frequently shuts down, it may need aircon compressor servicing or professional repair.

Homeowners often delay calling technicians, hoping the problem resolves itself. Unfortunately, waiting usually increases repair costs.

Prevent Problems Before They Start

The majority of aircon breakdowns are preventable. Regular maintenance is always cheaper than emergency repair.

A proper maintenance plan includes:

• Quarterly aircon general servicing

• Annual aircon chemical overhaul

• Checking refrigerant pressure

• Cleaning the drainage system

• Inspecting electrical components

That’s why many homeowners choose an aircon service contract with ongoing maintenance visits.

Save Money With Preventive Care

People usually search Google only when the aircon fails — but preventive care avoids panic situations.

Benefits of regular servicing:

• Lower electricity bills

• Stronger cooling performance

• Longer compressor lifespan

• Fewer emergency repairs

• Eligibility for seasonal aircon promotion

Final Thoughts

Whether it’s aircon not cold, aircon water leaking, aircon light blinking, or an aircon error code, your air conditioner always gives warning signs before major failure.

The key is early action:

• Book aircon servicing singapore

• Repair faults immediately

• Maintain a routine servicing schedule

Waiting too long often turns a simple cleaning into a costly replacement.

If your aircon shows any of these symptoms, professional inspection is the smartest and most affordable solution.
