Is your Midea aircon not cold even after running for hours? This is one of the most common problems faced by homeowners in Singapore. When your air conditioner is not cooling properly, it can make your room uncomfortable, especially in Singapore’s hot and humid weather.
There are several reasons why a Midea aircon is not cooling, and some problems are simple to fix, while others require professional repair. In this guide, we will explain everything clearly so you can understand the cause and decide the best solution.
How Does a Midea Aircon Cooling System Work?
Before fixing the issue, it is important to understand how your Midea air conditioner works.
An aircon cools your room by:
- Absorbing warm air from the room
- Passing it through cooling coils filled with refrigerant gas
- Releasing cool air back into the room
- Pushing heat outside through the compressor and condenser
If any part of this process fails, your Midea aircon may not blow cold air.
Common Reasons Why Midea Aircon Is Not Cooling
Dirty Air Filter
A clogged air filter blocks airflow. When air cannot pass through properly, your Midea aircon will not cool efficiently.
Solution:
Clean the air filter every 2–4 weeks.
Low Refrigerant Gas (Gas Leak Problem)
If your Midea aircon is not cold, low refrigerant gas could be the reason. Gas does not reduce normally — it usually means there is a leakage.
Signs of gas leak:
- Weak cooling
- Ice formation on pipes
- Hissing sound
⚠ Gas top-up alone is not a permanent solution. Proper leakage repair is required.
Compressor Not Working
The compressor is the heart of the aircon. If it fails, the unit may run but not cool.
Symptoms:
- Outdoor unit not running
- Loud noise
- Air blowing but not cold
This requires professional Midea aircon repair.
Wrong Thermostat Setting
Sometimes the issue is simple:
- Temperature set too high
- Fan mode instead of cool mode
- Timer activated
Always check the remote settings first.
Dirty Condenser Coil
The outdoor unit may collect dust and dirt, which reduces heat release efficiency. This makes the aircon not cold in Singapore’s hot weather.
Professional chemical cleaning may be required.
Faulty Fan Motor
If the indoor or outdoor fan motor fails, airflow becomes weak, and cooling reduces.
You may notice:
- Weak air flow
- Strange noises
- Overheating
Blocked Drainage System
If drainage is clogged, it may affect performance and cause water leakage along with cooling issues.

How to Fix Midea Aircon Not Cold (Basic Troubleshooting)
Before calling a technician, try these steps:
✅ Clean the air filter
✅ Check temperature setting (Set to 22–24°C)
✅ Ensure cool mode is activated
✅ Check circuit breaker
✅ Look for visible water leakage
If the problem continues, professional inspection is recommended.
When Should You Call a Midea Aircon Repair Specialist?
You should contact a technician if:
- Aircon not cooling after cleaning
- Gas leakage suspected
- Compressor not working
- Error codes appear
- Water leaking continuously
Professional technicians can properly diagnose and fix the issue without damaging internal components.
How Much Does It Cost to Fix a Midea Aircon in Singapore?
Repair cost depends on the problem:
- Minor servicing: Lower cost
- Gas top-up with leak repair: Moderate
- Compressor repair: Higher cost
It is always better to do a proper inspection before deciding.
How to Prevent Midea Aircon From Losing Cooling Again
To maintain strong cooling performance:
✔ Service every 3–6 months
✔ Clean filters regularly
✔ Do annual chemical wash if needed
✔ Check for unusual noise early
✔ Avoid overusing at very low temperatures
Regular maintenance prevents major Midea aircon not cooling problems.
Frequently Asked Questions
Why is my Midea aircon not cold but the fan is working?
If your Midea aircon is not cold but the fan is working, the issue is usually related to low refrigerant gas, a faulty compressor, or dirty cooling coils. The fan may circulate air normally, but without proper cooling function, the air will not be cold. A professional Midea aircon repair can diagnose the exact cause.
What causes a Midea air conditioner to stop cooling suddenly?
A Midea air conditioner not cooling suddenly can be caused by gas leakage, electrical faults, sensor failure, or a tripped circuit breaker. In Singapore’s hot weather, overloaded systems may also stop cooling. Early troubleshooting helps prevent major air conditioner repair costs.
Does low gas make my Midea aircon not cooling?
Yes, low refrigerant gas is one of the most common reasons for a Midea aircon not cooling. However, gas does not reduce naturally — it usually indicates a leak. Proper leakage repair should be done before any gas top-up to ensure long-term cooling performance.
How do I reset my Midea aircon when it is not cold?
To reset your Midea aircon not cold issue, turn off the unit and switch off the power supply for 5–10 minutes. Restart the system and check cooling mode settings. If the problem continues, professional Midea aircon repair in Singapore may be required.
Why is my Midea aircon running but not blowing cold air?
If your Midea aircon is running but not blowing cold air, possible causes include compressor failure, refrigerant leakage, or blocked condenser coils. The system may operate normally, but the cooling cycle is incomplete, requiring proper inspection and repair.
How much does it cost to fix a Midea aircon not cooling in Singapore?
The cost to fix a Midea aircon not cooling in Singapore depends on the problem. Minor servicing costs less, while gas leak repair or compressor replacement is higher. A proper diagnostic check ensures accurate pricing and avoids unnecessary repairs.
Is gas top-up enough if my Midea aircon is not cold?
Gas top-up alone is usually not enough if your Midea aircon is not cold. If there is a refrigerant leak, topping up gas without fixing the leak is only a temporary solution. Proper leakage detection and repair ensure long-lasting cooling.
Can a dirty filter cause Midea aircon cooling problems?
Yes, a dirty air filter restricts airflow and reduces cooling efficiency. When airflow is blocked, your Midea aircon may not cool properly. Regular cleaning every few weeks helps maintain strong cooling performance and reduces the need for repair.
Why is my Midea aircon compressor running but no cold air?
If the compressor is running but there is no cold air, the issue may involve low refrigerant levels, faulty valves, or internal compressor damage. Professional air conditioner repair is necessary to prevent further system failure.
When should I call a technician for Midea aircon repair?
You should call a technician if your Midea aircon is not cooling, leaking water, making unusual noise, or showing error codes. Early professional repair prevents higher costs and ensures safe, efficient operation in Singapore’s climate.
