and FIVE years part warranty for compressor !
B) Raw Material : Technical specification of common used material for installation of air conditioner system.
The Usual Problems
1) Water Leakage at Indoor Unit
Ans : Water leakage occurs when the water drainage pipe is choked with 'algae' and dirt thus causing the water from condensation inside the evaporator unit unable to flow smoothly into the drainage hole in the toilet. This is very normal and unavoidable. This usually occurs after 1.5 years to 2 years of usage. You just need to get a general service to flush through your drainage pipe. ( If you want to save money, then connect your vacuum cleaner head to the end of the drainage pipe. It does help a bit.. )
BUT!!! If this occurs just after a few months of installation and usage, it might mean the installation is not done properly. The drainage pipe might be installed too straight or titled to the wrong side.
2) Water Leakage from the trunking
Ans : Do not confuse this with condensation. Water leakage means water dripping from the trunking. ( condensation is water droplets forming on the trunking and drip little by little ) For such a case, the joints at the water drainage pipe might not have been connected properly or there might be some cracks in the water drainage pipe. Get the installer to check.
3) Condensation on the trunking
Ans : Water droplets forming on the trunking. This occurs when the environment is very humid. For example, the room closest to the outdoor unit is not using the air con but the room further away is using air con. In this case, condensation will occurs in the trunking of the nearer room. But this condensation is normal and pose little problem.
BUT!!! If you noticed the condensation occurs even in the air conditioned room or water kept dripping down, it means the insulation is not good enough. One of the solution is to increase the insulation thickness.
Do also take note, if you intend to conceal or run your trunking inside or behind false ceilings,L-box or wardrobe, please increase the thickness of the insulation to at least 1/2 inches or as recommended by the manufacture
4) Not cold enough
Ans : It can be due to insulation wear off thus exposing the copper pipe to the environment (especially near the outdoor unit) or the refrigerant is insufficent due to poor installation of copper pipe. In either way, get a general service.
Or your air con might be size wrongly. Or too many people in the room. Or the presence of heat source. Or you set your mode to 'FAN' instead of cool. Or your temperature is set too high. Or the air con is blowing at the wrong direction.
BUT!!!! If you have not been cleaning your dust fliter for the past few months, IT IS YOUR FAULT!!! Self maintenance is very important.
5) Compressor very noisy
Ans : If you have used the air conditioner for more than 4 years, that is quite normal as the compressor wear out due to daily usage. In addition, some parts may have loosen.
If you have bought an unknown air con brand, then blame on yourself.
If this occurs at the first 4 years, get someone to check as most manufacturers provide 5 year compressor warranty.
6) Indoor unit very noisy
Ans : The installation of the indoor unit is not done well. Thus when the indoor unit operates, the plastic cover knocks against the casing or the casing against the wall. But sometimes it may also be the uneven wall. This can be solve by slotting thin pieces to insulation sheets to try level the indoor unit.
7) Air con will not ON
Ans : Sensor spoil or remote control spoil. You just have get it repair.
Surely there may be other causes but too many to talk about.
Take note: remote controls are not under any warranty. You have to buy a new one when it spoils.
You can either choose to purchase
- a Univerisal remote controller from hardware stores.
- Original remote controller from the manufacturer or authorised dealer.
- 2nd hand remote controller from any air conditioner retail shops.
8) Water dripping from the outdoor unit
Ans : Many of you will have experienced your neighbour's (above) air con dripping water onto your outdoor unit every night, especially when the night is hot and humid. This is actually very normal as parts of the outdoor unit is cold (due to the refrigderant).
Generally, the above will drip onto you and you drip to the one below. So there should not be much of a complain.
But if you want to solve this problem, u can install a water tray below your outdoor unit.
*Not allowed currently due to "mosquito breeding" issue.
Another solution to wrap insulation sheets around those "cold" areas of the outdoor unit.
General Tips
1) Never install your indoor unit directly above your bed or electrical appliances as you never know when it is going to leak (water).
2) Do not flush the indoor unit to the ceiling as the flat panel indoor units are designed to have its air intake mostly from the top instead of the front.
3) Always try to minimise the piping length and not install the piping behind any cabinets or any inaccessible areas.
4) Do not use strong chemicals to clean the exterior of the indoor units, just a clean, stain free cloth will do. The exterior should only have dust so you need not scrub it.
5) Do not use hot water to clean the dust filter, it will deform the plastic. Use will cold water to flush through or use a vaccum cleaner. Please handle with care. It is fraglie.
6) Leave the dust filter to dry normally. Do not use hair dyer or leave in direct sunlight.
7) Do not attempt to dismantle and clean in the interior of the indoor units yourself as you will caused a lot of air con technicans to lose their jobs. In addition to that, improper assembly will cause excessive noise and vibration or worst, short circuit.
8) When quarreling with your other half, do not use the remote control as a weapon to throw at him/her, remote do not come cheap (on average about $100), try using the pillow instead.
9) Try not to set the temperture at 20'C or below, you are wasting energy. Research shows that 24'C is a comfortable temperature for most human. Surely there got to be exceptions, if a doctor have certified that you have a melting point of 24'C then go ahead set at 20'C.
10) Install your fan coil at a shaded area of the room or home.Why is my indoor unit noisy?
For those whose indoor unit is causing you to lose sleep every night, it might be due to the following reasons
1) The bracket securing the indoor unit to the wall is not screwed tightly thus causing 'rattling' noise when the indoor unit is in operation.
2) At times, due to the uneven wall, the indoor unit can never be mounted 'leveled' . Thus it is important to choose a solid support.
3) After sometime, there will be dust and dirt accumulated on the inner horizontal fan in the indoor unit. This caused virbrations. (due to 'additional' weight distributed unevenly on the fan, resulting in unbalanced force.
** For other models, you might have to dismantle the cover first, which is better left the professional, before you can gain access to the inner fan.
(It is not really that hard, just observed the next time someone comes down to do your air con servicing)
4) If u have used the air conditioner for years, it might be due to the normal wear and tear of the bearing and motor. In this case, you can either change the parts or live with it till you decided to get a new one.
5) It is normal for you to hear creaking noise especially when you on the air con initially. This is due to expansion and contraction of the cover.
