It is recommended that your air-conditioning is serviced annually, as you can lose 5-10% of refrigerant per year. What is more important is the system absorbs moisture which when mixed with the oil inside the system, it becomes acidic causing internal corrosion. This internal moisture is removed by a standard air conditioning service when the refrigerant is replaced.

Is your car making you sick? The air-conditioning system may also need to be disinfected to eliminate mouldy smells which are caused by mildew and fungi. It is excellent for refreshing smoked-in vehicles, older cars and trucks.

Every 2 to 3 years the filter drier within your air-conditioning system should be replaced. The filter dryer improves the efficiency of the system under full heat load (very hot days) providing far more effective cooling with improved fuel efficiency.

The filter dryer has three important functions within the air-conditioning system; the first function is to remove moisture. It should be pointed out that a filter drier is fully saturated with as little as 5 droplets of moisture. The second function is that they contain a filter. This fine filter becomes restricted or blocked in normal operation. The third function of the filter drier is its receiving or storing function

Interesting facts about your car air conditioning system

1.

Odd smells coming from the air conditioning may be caused by bacterial build-ups. As your car becomes older, or when the air conditioning system is used infrequently, bacteria, microorganisms, mould and fungi may start growing, just behind the dash panel on the evaporator causing some very unpleasant odours. Some even claim this can result in headaches and flu symptoms sometimes referred to as “sick car syndrome.” This problem can be solved by using our anti-bacterial ultra sonic clean treatment that destroys the bacteria growth and leaves your car smelling fresh again.

2.

Running the air conditioning system traps harmful pollutants and other allergy instigators through its moist evaporator core thus making it healthier driving in all conditions.

3.

Running your air conditioning year round will help maintain the system if you run the air conditioning in the winter, it dehumidifies to air inside the vehicle and defogs the windows quickly as well as to help to keep the system well lubricated and leak tight. This is because the refreigerant actually carries the oil that lubricates the system and most importantly the compressor. It also keeps the seals and hoses moist, thus preventing them from drying out and cracking which can lead to leaks.

4.

Strange noises coming from the air conditioning should be attended to immediately. If your air-con system suddenly starts making noises you have not heard before it is very advisable to have a qualified vehicle air conditioning specialist to have a look at it. Some noises could be early symptoms of a compressor failure (the compressor is the air conditioning pump). The compressor is usually the most expensive part on the system ranging from approximately $500-$2500+ and if the bearings in your compressor break down or if the compressor seizes up it also means that other components can become contaminated with metal particles. A flush of the system would then be needed as well as replacement of the compressor, the receiver/drier and the expansion valve – quite a hefty bill!

5.

Excessive moisture inside the car can be fixed easily. Sometimes the drain tube from the evaporator may become blocked or detached allowing the condensation to build up inside your evaporator. If this occurs water will just build up inside your car to a point where there are damp carpets or misting/high humidity type problems. These problems can be solved with low-cost servicing.

6.

It has been proved that air conditioning can save you money. At speeds 40kph+ 65% of cars consume more petrol with the windows rolled down than with the air conditioning turned on. This is due to the wind drag, having the cars windows open creates almost a wind stock effect, and this loads up your engine, thus consuming more petrol. The faster you go, the more wind you drag and the worse the consumption. (Try this one out on your next trip).

7.

Have your air conditioning serviced regularly, even if there are no visible problems. Just as the other systems of your car need servicing on a regular basis, the same is true for the air conditioning system. The compressor needs oil, or else it will seize up. The filter collects debris and moisture. If the filter becomes blocked, then the performance of the system will deteriorate to a point where it will work inefficiently, loading the compressor up, this in turn creates a larger load on the engine, consuming more fuel, left without checking it will quit working entirely (probably when you need it most!) Normally the refrigerant gas in a car air conditioning system has to be recharged completely within three years from the manufacture date and hereafter every year. An annual service of your car’s air conditioning system will guard against malfunctions in the compressor and other vital parts of the system. Regular maintenance will save you money in the long run and guarantee you comfort in the hottest months.
