Common Causes: 1) An unbalanced Condenser Fan blower. a) This is a very rare condition, but I’ve personally come across such before. Normally, the outdoor condenser fan has 3 fan blades. Should any of the fan blade breaks off, the fan will be so unbalanced in weight that it causes the entire condenser to vibrate vigorously. If […]

There are generally 3 types of power tripping: 1) It trips the ELCB (Earth Leak Circuit Breaker) or the RCCB (Residual Current Circuit Breaker). That’s the big circuit breaker with the blue lever. It is often installed on the left, the first one. It will be written ELCB or RCCB. If you are interested in what’s […]

Common Causes:Fear not! It may just be a very simple problem. This problem can be cause by a couple of  possibilities (ranking from the most probable): 1) A faulty miniature aircon ON/OFF switch. Most probable (and cheap to repair)2) A faulty aircon remote controller that keeps sending signal repeatedly.3) A faulty aircon PCB (printed circuit board, […]

What causes Aircon Gas Leak? Your aircon shouldn’t leak gas at all; if it was properly set up, gas will not leak even after 10-20 years!Now, lets take a good look at high risk areas where gas leaks often occur. 1) At the locking nut area. Picture of the nuts removed. The ‘o-ring’ seal will leak […]

You’ve spent a fortune renovating your house and after many years when the air conditioners are old. You’ll like to simply replace the air conditioners while keeping all the pipes. But, the pipes are leaking, and you wondered what had gone wrong? Pipe leakage is often caused by acid build up within the gas system […]

Tucked inside your PVC casing are the insulated copper pipes and PVC condensate water pipe. Under normal condition, there shouldn’t be any condensation.When there are abnormal condensation, it could be due to: 1) A dislodged PVC condensate water pipe due to poor installation. I shall try to explain this subject in layman terms, so engineers […]

This is the compressor, the heart of the air conditioning system. As you can see, it looks like two cylinders. The cylinder on the right is a liquid receiver, while the “cylinder” on the left is the compressor. This is a rotary compressor, the entire system is sealed up and compressor oil is poured into the […]

1) Compressor overheating : A compressor can overheat due to:a) A choked condenser or a condenser fan that is spinning too slowly.b) Too much or too little gas in the system. For more details, please read compressor.c) A worn out compressor.d) Compressor oil turned bad, thus generating high friction and heat. Read compressor.e) A choked drier […]

Ice usually form when suction gas pressure has dropped to ~ 40psi to 45psi (on a r22 system), ~ 80psi on a r410 system. As such, it could mean that your system has a problem of gas leak. However, if you see the entire fan coil turning into a block of ice, it is most likely caused […]

Ice forming on the small liquid line is an indication of low gas pressure. Either you have a gas leak or its due to a restricted valve/capillary tube. BUT!!! if it ice is on the suction line (picture below), do not top up gas. It means that the aircon in the room is not fully […]
