Air conditioning, which was once a great luxury, is currently a common feature on most car. While the servicing of modern car air conditioning systems is best left to professionals, you can get the most enjoyment from your air conditioning system if you have some idea a bit about how it works and what defectives you should watch for.

1. Weird smells coming from the air conditioning may be due to bacterial builds up

As your vehicle becomes older, or when the air conditioner system is used infrequently, bacteria, micro-organisms, mold and fungi may start increasing, just behind the dash panel on the evaporator causing some very undesirable odors. Some even allege this can bring about headaches and flu like symptom sometimes referred to as “sick car syndrome.”

This trouble could be resolved by using an anti-bacterial treatment method that ruins the bacteria growth and leaves your car interior smelling fresh again.

2. If you vehicle does not feel cold enough, then you may need to recharge your system

If you feel that your motor vehicle doesn’t feel as cold as your friend’s car, then your system may need servicing. The air conditioning system in your motor vehicle is not usually covered by most manufacturers servicing schedules and the refrigerant gas that is used to operate the system depletes as time go on. Typically most vehicles lose up to 15% per annum. This leakage can be caused when then system is not used during the winter months. Thus allowing the small “O” ring seals to dry bring about a gradual deterioration in system performance. If this continues, eventually the system will not be able to operate at all.

Most problems of this type can possibly be repaired fairly effortlessly by a leak check of your system followed by a complete refill of your air conditioning refrigerant, this is sometimes referred to as a re-gas.

3. Operating your air conditioner all year will help maintain car air-conditioning system.

If you run the air conditioner in the winter it will help to keep the system well lubricated and leak tight. This is because the refrigerant actually carries the oil that lubricates the aircon and most importantly the compressor. It also keeps the seals and hoses moist, thus preventing them from drying and cracking which can lead to leaks.

4. Strange noises coming from the ac system 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 a/c 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 air-con system and if the bearings in your compressor is damaged or if the compressor seizes up it also means that components can become tainted with metal particles A flush of AC would then be needed as well as replacement of the compressor, the receiver/drier and the expansion valve – quite a hefty bill!

5. Worry not about a pool of water forming under your vehicle after using the A/C

If you see a puddle of water on the floor, usually under the passenger area don’t be alarmed. This is a normal feature of the system as it is only water dripping from the air conditioner evaporator. The evaporator has a drain tube fitted to allow the condensation from the evaporator to drain away from the vehicle.

6. Excessive moisture inside the car may be fixed effortlessly

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 vehicle to a point where there are wet carpets or misting/ high humidity type problems These problems can be solved with low-cost auto servicing.

7. Have your air conditioner serviced frequently, even when there are no visible issues.

Just as the other systems of your car need servicing often, the same holds true for the a/c system. The compressor needs oil, otherwise it will seize up. The filter collects debris and moisture. If the filter becomes blocked, then the performance of the system will deteriorate and it can even quit working totally (probably when you need it most!).

Normally the refrigerant gas in a car air conditioner system has to be recharged thoroughly within four years from the manufacture period and thereafter every 2 to 3 years.

An annual car servicing of your car’s air-conditioning system will guard against malfunctions in the compressor and other essential parts of AC system. Regular maintenance will save you money down the road and ensure you comfort in the hottest months.
