Air Conditioner Refrigerant
All of us have probably heard about the ozone layer which is located 35 miles above the ground. This upper layer of our earth's atmosphere protects the earth from the sun's ultraviolet rays by reflecting them back to space. UV rays are harmful to the plant, marine life and human beings on the earth.
How does air conditioner relate to the ozone layer? It was discovered in the mid 1980s that the commonly used air conditioner refrigerant has a damaging impact on the ozone layer. At that time, the refrigerants that used then were known as CFC(chlorofluorocarbons) and HCFCs(hydrochlorofluorocarbons). CFCs are a family of chemicals that contain chlorine, fluorine and carbon. The chlorine content in these compounds cause the depletion of the ozone layer.
This discovery prompted the signing of Montreal Protocol of 1987, an agreement signed by 180 nations that target to phase out the production of CFCs by 1995 and HCFCs by 2030. New refrigerants that are being used to replace these CFCs are HFCs(hydrofluorocarbons) and refrigerant blends(Azeotropic, Zeotropic). In summary, the 4 commonly used refrigerants that you can find today are:
CFCs
HCFCs
HFCs
Refrigerant blends
The future commonly used refrigerants will be in the last two categories. Among the currently widely used ones are R-134a, R407C and R410A.
CFC Refrigerants
These refrigerants were developed more than 70 years ago and are harmful to our respiratory systems and the ozone layer. Their production was stopped since 1995 but are still being used widely in existing residential air conditioning units as many equipments have a lifetime of up to 30 years. Today's refrigerants used are from reclaimed units that are no longer in operation. The common ones still used are:
R-11
R-12
R-113
R-114
R-115
HCFC Refrigerants
These air conditioner refrigerant is considered partially halogenated as they consists of methane or ethane in combination with chlorine and fluorine. They are shorter lifespan and are less destructive to the ozone layer compared to CFCs. They are an interim solution to a totally "free from chlorine" refrigerant that are being developed. Their production are scheduled to be phased out totally in 2030. The common ones used are:
R-22
R-123
R-22 is used extensively in residential, commercial and industrial applications.
The schedule of phaseout :
2015 - Production freeze and use limitations
2020 - Prohibited for new air conditioning and refrigeration use
2030 - Total phaseout
HFC Refrigerants
These air conditioner refrigerant contain no chlorine atom and is not destructive to the ozone layer though they have a slight effect on global warming. R-134a is used in new systems that are specially designed for its use. The common HFCs are:
R-134a
R-124
The 1997 Kyoto Protocol puts R-134a as one of the 6 greenhouse gases that must be reduced. There is no phaseout date for this refrigerant and it is expected to be highly used in the HVAC industry.
Refrigerant Blends
These air conditioner refrigerant are also known as "azeotropic" and"zeotropic". Their use is increasing as they are environmental friendly. The setback is that the total air conditioning systems production cost is higher. However, as more manufacturers switch to this type of refrigerants, the cost/unit will drop eventually. The common refrigerant blends used in the air conditioning industry are:
R-410A
R-407c
R-410A are used as a replacement refrigerant for residential air conditioning applications.
R-407C are used as R-22 replacement.
Recovery, Recycling and Reclaiming of Refrigerants
Laws have been passed to prevent the release of CFC refrigerants into the atmosphere. The steps taken are:
Recovery
The act of removing the refrigerant from a system and store it in an external container. No testing or processing is needed in any way.
Recycling
Refrigerant is cleaned for reuse by oil separation and passes though devices such as core filter-driers. This procedure reduce the moisture, matter and acidity of the refrigerant for reuse. It is usually done for jobs on the field or service shops.
Reclaiming
Reprocess the refrigerant to new product specifications which may include distillation process. This can only be done by manufacturing plants where chemical analysis is required. Highly equipped local service shops may have this facility as well.
Consumer Role
How can consumer like you play your part in the effect to keep our earth green? You can do that by purchasing air conditioning systems that uses new refrigerant such as R-134a, R-407C or R-410A. Most equipments are labelled with stickers that indicate the type of refrigerant used. Examples are "ozone friendly" sticker, "R-410A" sticker,..
Do your part to preserve mother nature...

Frequently Asked Question For Air Conditioner
Q. What type of air conditioner are we usually using in Malaysia now?
A: In Malaysia we usually use split type air conditioner. Split type means there is an outdoor unit and indoor unit for a set air conditioner. The outdoor unit carries compressor, and etc within it and it is usually installed at outdoor of our residential. Indoor unit is the unit providing cooling air in the designated room which comprises circuit board and etc within it.
Q. Currently in Malaysia there are a lot of air conditioners brand are pushing on inverter type air conditioner which is known as more energy saving than normal split type air conditioner. So what does exactly inverter mean?
A: An inverter air conditioner uses an inverter circuit(mainboard) to regulate the rotational speed of the compressor to match the output of the compressor to the cooling pump load. This reduces the number of times the compressor stops and starts as the load varies, so saving on electricity bills and reducing noise levels compared to non-inverter models
Q. How long is the warranty period for each air conditioner?
A: Generally in Malaysia, most air conditioners come with ONE year warranty (parts & labor for repair excluding servicing) and FIVE years part warranty for compressor.
Note : 1hp to 2.5hp the compressor warranty is 5 years
Above 2.5hp the compressor warranty is 1 year
For Daikin Brand air conditioner their compressor warranty up to 20hp is 5 years.
Q. What is the average life span for an air conditioner?
A: The average life span of an air conditioner is about 6-7 years, but it can be prolonged through proper maintenance by qualified technicians on a regular basis.
Q. Can we do the general service by ourselves and how often?
A: Cleaning of fan coil and the cover of the air condition can be done easily but to take out the water tray will be tough for some people. To vacuum the drainage system and to check the refrigeration level cannot be done without proper equipment.
Basically, it is recommended that residential air conditioner is to be service and check every 3 months and every month for commercial air conditioner. The duration of how often to service the air conditioners is varies with the different usage pattern and environmental factors. Please seek the assessment from a qualified technician.
Q. What is the reason when the aircond is operating but it doesn't provide any cold air?
A: The air conditioning system consists of two sectors with different functions. The indoor fancoil and the outdoor condenser. The indoor act as a blower to dissipate the cooling generated by the outdoor condenser. If there is no cool air blowing out from the indoor fancoil, it may cause by the following factors.
1. Air filters dirty
2. Object blocking the air inlet/outlet of the indoor/outdoor units.
3. Aircond temperature is set too high.
4. Windows and doors are opened.
5. Airflow direction is not appropriately set.
6. Remote control is not in the cooling mode.
7. Parts may be faulty.
8. Fan motor is clog with dust. Thus, cool air is being blocked, therefore cannot be blown out.
9. The air conditioner installed is undersized
10. Not enough refrigerant in the air conditioning system. Please contact a qualified service
technician to attend to your air conditioner.
Q. Why is the air conditioner leaking water?
A. Water from the air condition is discharged out through a drainage pipe that is run from the fan coil unit to the nearest drain. Water will start to leak from the fan coil if :
1. The drainage / pan or pipe could have been blocked due to some dirt being accumulated at
these area.
2. Aircond could be dirty
3. Poor gradient of the drainage pipe. Installer use smaller pipe size for the drainage pipe
Q.Why does water drip from the condenser (Outdoor unit)?
A. It is normal for water to drip from the condenser as condensation takes places when the warm air surrounds the piping condensate.
Q. Why does ice-form on the copper pipe of the condenser (outdoor) unit?
A. There are two possibilities. Ice-forming on the discharged pipe (the smaller sized one) is due to insufficient gas in the system. Ice-formation on the suction pipe (the bigger one) could be caused by a dirty fan coil unit or, a dirty filter or, the indoor unit blower is not rotating. A qualified technician should engaged to have the air conditioner repair.
Q. Why does the air conditioner produce a foul smell?
A. This is due to the smell of the room, furniture, or cigarettes being absorbed into the unit and is discharged together with the airflow. Please contract qualified serviceman to service your air conditioner in the event the air con produce a foul smell.
Q. What happen if I do not service my aircon?
A. The life span of the air conditioner will be shortened, coolness decreases with usage and water leaking problem may occur as a result of a choke drainage system. The inefficient operation will then cause the electricity consumption to increase.
Q. Do we need to service the Condensing (outdoors) unit? If, yes, how often?
A. You need to clean the condensing unit at least once a year to make sure the air circulation of the unit is not blocked. If you didn't service the outdoor condenser, then it can affect the cooling efficiency, shorter compressor life and even increase your electrical bill. Sometimes, it is subjected to environmental condition, which requires a qualified technician to give recommendations.
Q. When does the air conditioner needs Chemical overhaul and chemical cleaning ?
A. When your air conditioner starts blowing badly smell from the indoor fancoil, you should engaged a qualified technician to do chemical cleaning. The smell comes from the bacteria formed by microbes in the warm dark humid environment in the indoor fancoil unit. Chemical overhaul is need when your air conditioners is badly clogged / choked whereby the general servicing can not improve the condition. In an overhaul, the air conditioner is dismantle part by part and chemically wash.
Q. What should be done, if there is a refrigerant leakage problem?
A. If your air conditioner system has a refrigerant leakage problem, simply adding of refrigerant (R22 / R410A) is not a solution. A qualified technician should be engaged to trace and repair the leakage. Upon completion of the repair , a correct amount of refrigerant should be top up
