Car Air Conditioning Service
De Jonge Mechanical can arrange all of your Automotive Air Conditioner repairs, service and inspections in Albany and the surrounding areas.
Todays vehicles are very complex and just like the engine, a typical car air conditioning system has elements that need to be serviced or replaced on a regular basis.
Don’t Melt In Your Car
Send the heat packing. Automotive air conditioning systems use refrigerant to remove excess heat from the air in the passenger area of the car then send it outside, leaving only cooled or 'conditioned' air to be recirculated. It's therefore crucial that the rubber seals are studied for any signs of leaks or cracks which could be a sign of a loss of refrigerant.
As refrigerant levels decrease from evaporation or leaks your air con system will begin to deteriorate and have to work harder with a resulting increase in fuel being used up. Even new cars can lose approximately twenty percent of their refrigerant gas in the first two years.
To run in optimum condition it is strongly recommended that the refrigerant in your Car Air Conditioner is recharged completely within four years of the manufacture date and every two to three years after that.
An annual car air conditioner service means you generally assist prevention of costly breakdowns now and in the future - and a well serviced Car Air Conditioning system actually saves you money because it means less fuel is being expended.
You should have your Air Conditioning unit checked on a regular basis to make sure the air conditioning system continues performing correctly as well as having the mechanics review the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and are usually able to alert you to any components that may need replacing in the near future or those that are already damaged beyond repair.
De Jonge Mechanical Pty Ltd in Albany can arrange air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
An automotive air conditioning system is made up of of four basic parts - a pump, driven by a belt, called a compressor (to compress and ciculate refrigerant gas), a radiator like unit called a condenser (redistributes heat and condenses gas to a liquid), a heat exchanger called an evaporator to withdraw heat from the car and remove moisture from refrigerant and an expansion device either a thermal expansion valve (TXV) or an orifice tube, (dependent on the type of A/C system used).
Your car air conditioner is designed to remove the heat from the air in the vehicle then send it outside, leaving only cooled or 'conditioned' air to be recirculated. As hot air is passed across the fins of the evaporator the heat is easily absorbed by the refrigerant (in gas form), effectively removing the heat from the air in the car and taking it outside.
The now heated gas is pulled through the compressor where it is further heated (via compression) to a very high temperature. The refrigerant is then literally forced through the condenser, allowing the cooler outside air to quickly extract the heat from the refrigerant as it is condensed to a liquid. The refrigerant then moves through the expansion device (either a TXV or Orifice tube), which regulates the flow of refrigerant going to the evaporator. At this point the refrigerant expands back into a gas form and the entire process begins all over again.
What is involved in a car air conditioning service?
A typical air conditioner service may include
Make sure air vent temperature is correct
- Condenser temperature assessment
- Check suction line temperature
- Drive belt and pulley correction
- Check correct operation of valves and thermostats
- Clean the fins of the condenser
- Assessment of hose and component condition
- Evacuation and recharge of refrigerant (where required)
- Use electronic leak detector to check system lines and components for leaks
Why do I need a car air conditioner system service?
By checking or changing the oil level in the refrigerant you protect the compressor and save it from seizing up. Should the air filters be plugged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit completely. Along with reducing air conditioner performance, dirty air filters can cause all kinds of health problems too.
An automotive air conditioning system must be checked for problems yearly for any signs of problems with the connections, hoses and seals to make sure refrigerant is not leaking over time. Regularly servicing your automotive air con system keeps refrigerant at optimum levels meaning the system does not need to work as hard and this in turn protects the system from damage and minimises fuel usage.
Your car air conditioner is designed to remove the heat from the air in the vehicle and relocate it outside, leaving only cooled or 'conditioned' air to be recirculated. This is achieved using a special compound called refrigerant, capable of readily absorbing heat as a gas and quickly losing heat as a liquid.
While it carries out its task similarly to a domestic refrigerator, there are some significant differences. Because it is mounted on your car, the air conditioning unit is subject to a colossal amount of movement and vibration as well as performing in an outdoor environment.
Being exposed to the mercy of the elements and very harsh operating conditions and being switched on intermittently rather than being 'Always On' can cause issues with the hoses, connections and seals. A vehicle air conditioner ought to be examined annually as well as being properly serviced every 24 months to ensure there are no problems or refrigerant loss due to failure or leakage from these points.
Simply by cooling the air in your car under normal running conditions, the filters of the air con get dirty. If the system is run infrequently, seals may dry and crack allowing them to leak and the air conditioning system can lose as much as 15% of its refrigerant in a single year. Even without leaks, the gas in a car air conditioning system will eventually degrade or evaporate over time and should be recharged regularly to keep the air con system in peak running condition
Under Australian law, only qualified mechanics with the appropriate licences are able to service or repair car air conditioning systems, especially where regas (recharging of the refrigerant) is concerned. Strict guidelines and procedures must be adhered to when handling refrigerant, which must always be fully recovered and not allowed to escape into the atmosphere during servicing.
Refrigerant can also pose serious health risks if handled incorrectly. Specialist equipment is also required as the air conditioning system is under extreme pressure and must be pulled into a deep vacuum to remove any moisture, which can seriously damage the system.You can find out more about licensing on the Australian Refrigeration Council (ARC) Website.
The evaporator core can become a breeding ground for microbes, bacteria and even fungus due to the damp environment. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. Although modern evaporator units tend to be more efficient, the addition of extra fins leads to an increased ability to trap moisture, allowing micro-organism development.
De Jonge Mechanical Pty Ltd mechanics can use special ultrasonic technology to ensure the eradication of any micro-organisms that may cause unpleasant odours or health issues.Just ask about our MIST service, which will kill any bacteria that may be lurking in your Car’s Air system. These bacteria can cause odours and even make you sick, especially if you have allergies or asthma. A MIST service doesn’t just make your car smell better - it makes it healthier for you and your family.
