Car Air Conditioning Service
Marks Mechanics are ready to undertake all of your Car Air Conditioning repairs, service and inspections in Townsville and the surrounding areas.
We are licensed by ARC (authorisation#AU07715) and provide professional air conditioning service and regas.
Todays cars are often very complex and just like the engine, servicing your car's air conditioner regularly is very important.
Don’t Melt In Your Car
Send the heat packing. Automotive air conditioner systems use refrigerant to extract the heat from the air inside the vehicle and transfer it outside, leaving only cooled or 'conditioned' air to be recirculated. Therefore it should be considered essential to examine the condition of the rubber seals for any signs of leaks or fractures which could indicate a loss of refrigerant.
Losing refrigerant through evaporation or leakage generally means your air con system will begin to deteriorate and have to work harder increasing your fuel usage. Even new cars can lose as much as 20% of their refrigerant gas in the first 2 years.
To compensate for this situation it is strongly recommended that the refrigerant in your Automotive Air Conditioning system is recharged completely within four years of the manufacture date and every two to three years after that.
Getting your car's air conditioning serviced every 12 months means you assist in protecting the air-con against costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioner actually saves you money because it results in a reduction of fuel consumed.
Your car should be brought to a qualified workshop such as Marks Mechanics regularly to make sure the air conditioning system continues performing in optimum conditon as well as having the mechanics inspect the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and are often able to alert you to any items that may need replacement in the near future or those that are already worn beyond repair.
Marks Mechanics in Townsville are qualified to perform 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 compressor (Pump driven by the engine,) which compresses and circulates refrigerant gas, the condenser to remove heat and condense gas to a liquid, the evaporator (a type of heat exchanger) to exhaust the heat from the car and remove moisture from refrigerant and an expansion device either an orifice tube or a thermal expansion valve (TXV), (subject to the sort of air conditioner system used).
A car air conditioning is designed to extract the excess heat from the air in the passenger area of the car and transfer it outside, leaving only cooled or 'conditioned' air to be redistributed. 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 takes place in a a car air conditioning service?
A typical air conditioner service may include
Air vent temperature test
- Confirm condenser temperature correct
- Suction line temperature inspection
- Corrections of pulley and drive belt
- Ensure correct operation of thermostats and valves
- Ensure cleanliness of the condenser fins
- Inspect condition of of hoses and components
- Evacuation and recharge of refrigerant (where required)
- Use electronic leak detector to ensure no components or system lines leak
Why do I need a car air conditioner system service?
Seizing of the compressor can be prevented by checking or changing the oil in the refrigerant. Should the air filters become jammed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to cease to work completely. On top of impacting air conditioner performance, dirty air filters can cause all kinds of health problems too.
A vehicle air conditioner system ought to be examined yearly for any signs of failures in the connections, seals and hoses and confirm refrigerant is not being lost over time. Regularly servicing your vehicle 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 reduces the amount of fuel you burn.
A car air conditioning is designed to extract the excess heat from the air in the passenger area of the car then transfer it outside, leaving only cooled or 'conditioned' air to be redistributed. This is achieved using a special compound called refrigerant, capable of readily absorbing heat as a gas and quickly losing heat as a liquid.
Even though it carries out its task in a similar way to a domestic refrigerator, there are some crucial differences. Being mounted on your car, the air conditioner is subject to an astronomical amount of movement and vibration in addition to having to operate outdoors.
Being exposed to the mercy of the elements and very diverse operating temperatures and being run occasionally rather than being 'Always On' can have a detrimental effect on the connections, hoses and seals. Your air conditioning System should be examined annually while being properly serviced at least every two years 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 moist 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 they have more fins, meaning an increased capability to trap moisture and allow for micro-organism development.
Marks Mechanics mechanics make use of specialist ultrasonic technology to eliminate any micro-organisms that may cause unpleasant odours or health concerns.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.
