Below are the 5 main reasons why your aircon is not cooling your house, and what you should do about it.
1. Dirty Aircon Filters and Fan Coil Unit
One of the most common reasons for aircon not cold is dirty air filters. Over time, dust, dirt, and debris accumulate inside the fan coil unit, restricting airflow. When airflow is blocked, cool air cannot circulate properly throughout your home.
Signs to look out for:
- Weak airflow from the aircon
- The room takes longer to cool
- Musty or dusty smell when aircon is running
Solution:
Regular aircon servicing in Singapore is essential. At Letscool Aircon, our general servicing includes thorough filter cleaning to restore airflow and cooling efficiency.
2. Low or Leaking Refrigerant Gas
Refrigerant gas is responsible for absorbing heat and producing cool air. If your system has a gas leak or low gas level, your aircon will blow air but won’t cool effectively.
Common symptoms:
- Aircon runs continuously but room stays warm
- Hissing sound from the unit
- Ice forming on copper pipes
Solution:
Aircon Gas topup without fixing leaks is not recommended. Our technicians at Letscool Aircon perform proper leak detection and professional aircon repair Singapore to ensure long-term performance.
3. Faulty Compressor or Outdoor Unit Issues
The compressor is the heart of your air conditioning system. If it is faulty or the outdoor unit is dirty or overheating, the aircon cannot cool efficiently.
Warning signs:
- Outdoor unit not running
- Loud or unusual noises
- Aircon trips frequently
Solution:
A detailed inspection by experienced technicians is required. Letscool Aircon provides expert diagnostics and repair for all major brands, ensuring your system runs smoothly again.
4. Incorrect Aircon Size or Poor Installation
If your aircon unit is too small for the room size or was installed incorrectly, it will struggle to cool your house effectively, no matter how long it runs.
Common issues include:
Aircon cools only part of the room
Uneven temperature distribution
High electricity bills
Solution:
A professional site survey is crucial. Letscool Aircon offers free site surveys to recommend the correct aircon capacity and ensure proper installation for maximum cooling efficiency.
5. Lack of Regular Maintenance
Many homeowners only call for service when the aircon stops working completely. However, skipping routine maintenance leads to performance issues, higher energy consumption, and unexpected breakdowns.
Problems caused by poor maintenance:
Reduced cooling performance
Water leakage
Shorter aircon lifespan
