Hitachi Aircon Not Cold
Is your Hitachi aircon not cold even after a recent servicing? Many homeowners in Singapore face this frustrating issue. You expect your unit to perform better after maintenance, but instead, the cooling is weak or inconsistent. If your aircon not cold problem persists, there could be several underlying reasons. In this guide, Letscool Aircon and Services Singapore explains why this happens and what you should do next.
Incorrect or Incomplete Aircon General Servicing
One common reason your Hitachi unit is not cooling properly is incomplete aircon general servicing. Basic cleaning may remove surface dust from filters and panels, but it may not address deeper internal dirt buildup.
During professional aircon servicing in Singapore, technicians should check filters, fan coils, drainage systems, and refrigerant pressure. If servicing is rushed or not done thoroughly, airflow can remain blocked, resulting in poor cooling performance.

Refrigerant Level Issues (Aircon Gas Top Up Required)
Another major cause of aircon not cold after servicing is low refrigerant levels. If your technician did not check for leaks or skipped an aircon gas top-up, your Hitachi unit may continue blowing warm air.
Low gas levels often cause:
- Weak airflow
- Longer cooling time
- Higher electricity bills
- Ice formation on coils
If your unit also shows an aircon error code or aircon light blinking, it may indicate refrigerant imbalance. A proper gas pressure check and leak inspection during aircon repair singapore is essential.

Dirty Coil – Chemical Wash or Steam Wash Needed
Sometimes, general servicing is not enough. If your unit has not been cleaned for a long time, the evaporator coil may be heavily clogged with dirt and bacteria. In such cases, an aircon chemical wash or aircon steam wash is necessary.
A chemical wash removes stubborn dirt inside the coil system. For older or severely blocked units, an aircon chemical overhaul may be required. This involves dismantling the unit for deep cleaning.
Without proper deep cleaning, your Hitachi aircon not cold issue will persist even after basic maintenance.
Aircon Compressor Problems
The compressor is the heart of your air conditioning system. If the compressor is weak or faulty, the aircon will not produce sufficient cooling even after servicing.
Common compressor-related signs include:
- Loud noise from the outdoor unit
- The unit is running but not cooling
- Frequent tripping
- Aircon light blinking
Professional aircon compressor servicing can diagnose whether the compressor needs repair or replacement. Sometimes, damaged aircon spare parts such as capacitors or relays can affect compressor performance.
If ignored, compressor failure can lead to expensive repairs. That’s why regular inspection under an aircon service contract is highly recommended.
Water Leakage Affecting Cooling Performance
Did you notice aircon water leaking after servicing? A clogged drainage pipe or improper installation can cause water to accumulate inside the unit. When drainage is blocked, airflow efficiency reduces and cooling performance drops.

- Midea Aircon water leaking
- Mitsubishi Aircon Water Leaking
- Panasonic Aircon Water Leaking
Improper servicing may disturb the drainage alignment, leading to water dripping issues. If not fixed early, it can damage internal components and cause aircon not cold again.
Professional aircon servicing Singapore should always include drainage flushing and leak testing to prevent recurring problems.
Installation Errors or Spare Part Issues
In some cases, the problem is not servicing but previous aircon installation singapore mistakes. Poor piping, incorrect gas charging, or improper insulation can reduce cooling performance.
