If your AC has a refrigerant leak problem, adding refrigerant is not a solution. An experienced and trained technician will be able to perform diagnostic test to locate the leak and fix it.

Bad odour arises from bacteria formed inside a dirty evaporator (indoor fan unit). If the odour is too strong, you may need thorough cleaning done by professional technicians from a reliable and authorised air conditioning company.

The existence of damage to electronic components (electronic circuit board) inside the indoor unit that serves to regulate the evaporative process can result in the AC often turns on and off alone. Problems can be solved by performing component repair and replacement.

In AC units there is usually water condensate inside the evaporator and released through drainage/drainage pipes. Disposal channels clogged with dirt will cause leakage. Another possibility is that the refrigerant is too small, or it could be caused by improper installation of a disposal pipe.

Noise can be caused by:

• The vibrations caused by the evaporator and condenser when they are dirty
• The components inside the AC unit may be loose
• The components inside the AC unit may be damaged

Air conditioner basically consists of 2 parts; Evaporator (indoor fan unit) and condenser (outdoor unit). Evaporator acts as a blower to blow cold air produced by condenser. If there is no cold air coming out of the evaporator then the condenser may not work. Another possibility is:

• The air conditioner unit is too small
• Refrigerant (R22) gas (Freon) may be exhausted
• Dirty condenser resulting in an inability to produce air cold
• The temperature setting is too high
• Dirty evaporator resulting in the weakness of cold air
• Incorrect AC placement

One common cause is the lack of power to the AC unit. Check the electrical panel to ensure that the AC power supply is not cut off. If problem persists, call an electrician, or call NCG Air, and our experienced technicians will be able to solve this electrical problem in your air conditioning units.

Also check if the AC remote control needs new batteries to be replaced.

However, if you wish to keep your air conditioner in good working condition for its life span, it is recommended to sign up for maintenance package provided by reliable and authorised air conditioning company.

You need a condenser (outdoor unit) servicing at least once a year to ensure air circulation in the AC system is not hampered as this may lead to cooling inefficiencies, shorten AC compressor life span and electrical waste. To find out if it is necessary to do this condenser service, consult with an experienced technician from a reliable air conditioning company.
