Car Air Conditioning Service
G-Mac Auto Centre are certified to carry out all of your Automotive Air Conditioner repair, inspections or servicing in Myaree and the surrounding areas.
Todays vehicles can be very complex and just like the engine, a vehicles air conditioner has components that need to be serviced or replaced on a regular basis.
Don’t Melt In Your Car
Send the heat packing. A car air conditioner uses refrigerant to absorb heat from the air in the inside of the vehicle and transfer it to the outside, leaving only cooled or 'conditioned' air behind to be redistributed. Therefore it should be considered important to undertake a check of the condition of the rubber seals for any signs of leaks or failure which could be a warning of a loss of refrigerant.
Reduction of refrigerant through leaks or evaporation means your air con system will begin to deteriorate and have to work harder with a resulting increase in fuel expenditure. Even new cars can lose around 20% of their refrigerant gas within 2 years of purchase.
To avoid this happening it is strongly recommended that the refrigerant in your Vehicle Air Conditioner is refilled completely within four years of the manufacture date and every two to three years after that.
By getting a car air conditioning service every twelve months you may assist preventing costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioner system actually saves you money because it reduces fuel consumption.
You should take your car to a qualified workshop such as G-Mac Auto Centre on a regular basis to make sure the air conditioning system continues performing as it should as well as having the mechanics advise you on the condition of the entire car.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and can alert you to any components that may need replacing in the near future or those that are already worn beyond repair.
G-Mac Auto Centre in Myaree are qualified to conduct air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
A car air conditioning system contains four basic parts - a pump driven by a belt, known as a compressor (to compress and ciculate gas), a radiator like unit called a condenser (dissipates heat and condense gas to a liquid), the evaporator (a type of heat exchanger) to exhaust the heat from the car and dehumidify refrigerant and an expansion device called an orifice tube or a thermal expansion valve (TXV), (depending on the type of air-con system used).
A vehicle air conditioning system is designed to extract excess heat from the air in the inside of the car and transfer it out of the vehicle, leaving only cooled or 'conditioned' air behind 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 does a car air conditioning service consist of?
A typical air conditioner service may include
Test air vent temperature
- Condenser temperature inspection
- Suction line temperature assessment
- Ensure correct drive belt & pulley operation
- Operational check of thermostats and valves
- Ensure condenser fins are clean
- Check condition of of hoses and components
- 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?
Checking or changing the oil level in the refrigerant can prevent the compressor seizing up. Air filters overwhelmed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to stop operating completely. In addition to degrading air conditioner performance, dirty air filters can cause all kinds of health problems too.
Your car air conditioning system needs to be examined annually for any signs of problems with the connections, hoses and seals to make sure refrigerant pressure is being maintained over time. Regularly servicing your car air conditioning 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 consumed.
A vehicle air conditioning system is designed to extract excess heat from the air in the inside of the car then carry it out of the vehicle, leaving only cooled or 'conditioned' air behind 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 in a similar way to a domestic refrigerator, there are a couple of significant differences. As it is mounted on your car, the air conditioner is subjected to a gigantic amount of movement and vibration in addition to functioning outdoors.
Being exposed to the elements and very extreme operating temperatures and being switched on occasionally rather than being 'Always On' can cause decay of the connections, seals and hoses. Your air conditioning System must be checked yearly while 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 be the perfect breeding ground for microbes, bacteria and even fungus due to the moist conditions found there. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. Newer type evaporator units tend to be more efficient, yet have increased capability to trap moisture and allow for micro-organism development.
G-Mac Auto Centre mechanics have access to specialist ultrasonic technology to kill any micro-organisms that may cause bad 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.
