Aircon Service & Repair Questions

The air conditioning system basically comprises of 2 sections. The indoor fan coil and the outdoor condenser. The indoor fan coil simply act as a blower to dissipate the cooling generated by the outdoor condenser. If there is no cool air blowing out from the indoor fan coil, the outdoor condenser might not be working. A qualified technician is needed to troubleshoot on the outdoor condenser. For more info, click on this article “Why is the aircon not cold

A normal air conditioner will have water condensate in the indoor fan coil and discharge through a draining pipe to the nearest drain. The Air Conditioner will start leaking water when the drainage piping is clogged / choked. General aircon servicing normally involves the vacuuming of the drain pipe which may rectify the pipe chokage. For more info, click on this article “Why is the aircon leaking

There are a number of causes to this air conditioner not cold situation

Below are some reason;

  1. The indoor fan coil is dirty resulting in weak dissipation of cool air.
  2. The outdoor condenser is dirty resulting in incapable of producing cooling refrigerant.
  3. There may not be enough refrigerant in the air conditioning system.
  4. There might be some problem with the air conditioning system resulting in non-continuous operation of he system.
  5. The desired operating temperature is set too high.
  6. The air conditioner installed is under-sized.

The smell comes from bacteria formed by microbes in the warm dark humid environment in the indoor fan coil unit. Sometimes when the smell is very bad you may need a more intensive chemical treatment to rectify this problem. For more info, click on this article “Why is the aircon smelly

Chemical overhaul/cleaning is a very thorough way of cleaning the air conditioner. When an air conditioner is badly clogged/ choked and a general service can’t improve the condition, an overhaul is necessary. In an overhaul, the air conditioner is dismantle part by part and chemically wash. For more info, click on this article “Aircon chemical cleaning

By dismantling the fan coil unit, the air conditioning individual components can be washed thoroughly.

If your air conditioning system has a refrigerant gas leak problem, simply adding of refrigerant gas (R22 / R410A) is not a solution. A trained technician should perform pressure testing to trace and repair the leakage point. Upon completion of leaking repair, a correct amount of refrigerant gas should be top up.

You need to service the condenser (outdoor air conditioning unit) at least once a year to make sure the air circulation of the unit is not blocked. It can affect the cooling efficiency, a shorter compressor life and higher electrical consumption. Sometimes, it is subjected to environmental condition, which requires a qualified technician to give recommendations.

There are 2 possibilities. Ice-forming on the discharged pipe is due to insufficient gas in the system. Ice-formation on the suction pipe could be caused by a dirty fan coil unit or, a dirty filter or, the indoor unit blower is not rotating.

The blinking / flashing of indicator light indicate that there is a fault with the air conditioning system. Hence the air conditioner switches off by itself. A qualified technician is needed to diagnose and repair the fault. As this is a protective function to prevent the air conditioner from further damage, it is not advisable to do a electrical power reset to get the aircon temporary working. Continue operation might further damage the air conditioning system. For more info, click on this article “Aircon auto OFF problem

There is a fault with the indoor electronic circuit board. The circuit board controls the operation of the indoor fancoil and damage causes it to lose its operational control. A repair or replacement of the circuit board is necessary. For more info, click on this article “Aircon circuit board (PCB) problem

The fault might lies in the remote controller or the indoor printed circuit board. Try the remote controller on other fancoil and if it work, your remote controller is fine. If the fault lies in the printed circuit board, you need to engage a qualified technician to do repair on the printed circuit board.

When the refrigerant gas in an air conditioning system depletes away and the air conditioner needs to regularly top up refrigerant gas, we can suspect that there is air conditioning refrigerant leaking in the system. Pressure testing work will help to identify which is the leakage area. Normally high pressure is induced into the condenser, fan coil and refrigerant piping to identify where is the leakage. Further repair work will be quoted upon identifying the leakage area.

Note: Pressure testing work is a testing process (not repair work) to identify the leakage area. This work will not be able to rectify the fault but it’s a necessary process to define the scope of repair deriving from the result of the testing work. The leakage area defined herein is an indicative section of the refrigerant system. Our pressure test are unable to pinpoint leakage location.

Faulty air conditioner circuit board (PCB) can be repair in most cases. Many companies lacks the knowledge as well as are unwilling to spend time and effort on repair and testing of the circuit board. Its definitely less time consuming to replace a new circuit board. However the cost of replacing new circuit board is much more expensive. FIX-IT AIR CONDITIONER is among the few aircon companies in Nigeria that provide circuit board repair services. We are committed to cost saving for our customer. For more info, click on this article “Aircon circuit board (PCB) problem”

Air Conditioner Installation Questions

The following are some factors you should consider when choosing an air conditioning system.

  1. Determine the size of the area for which the air conditioner is require to cool.
  2. Determine the cooling capacity required (refer to question 2 under this section).
  3. Determine the brands and types of air conditioning you prefer.
  4. Workout and compare your budget.

An estimate calculation of cooling capacity for a room:

Area of Room [ Length (ft) x Width (ft) ] x 65 = “Cooling Capacity” BTU/Hr

Example: Room size is 12ft by 12ft. Cooling Capacity = (12ft x 12ft) x 65 = 9,360 BTU/hr

The general warranty given by most manufactures for residential aircon units are one (1) year on general parts and five (5) years on compressor. Please contact the respective manufactures to confirm their warranty.

The new R410A refrigerant compressor uses a different type of compressor lubricating oil. If piping is reuse, there could be a mixing of the oils which may lead to change in its properties. This could lead to possible breakdown of compressor. A cleaning must be carry out if piping is to be reuse.
