Car Air Conditioning Service
MD Auto Care are qualified to deal with all of your Vehicle Air Conditioner inspections, repair and servicing in Golden Square and the surrounding areas.
These days vehicles are often complex and just like the engine, your vehicles 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. A car air conditioner system uses refrigerant to absorb heat from the air in the interior of the car and expell it outside, leaving only cooled or 'conditioned' air to be recirculated. Therefore it should be considered essential that the rubber seals are appraised for any signs of leaks or decay which could be an indication of a loss of refrigerant.
Loss of refrigerant from evaporation or leakage means your air con system will begin to deteriorate and have to work harder raising the amount of fuel you use. Even new cars can lose around twenty percent of their refrigerant gas within 2 years of purchase.
To perform most efficiently it is strongly recommended that the refrigerant in your Automotive Air Conditioner system 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 can help protect against costly breakdowns now and in the future - and a well serviced Automotive Air Conditioner system actually saves you money because it burns less fuel.
Your vehicle should be inspected by a qualified workshop such as MD Auto Care (AU37017) regularly to ensure the air conditioner system continues performing at its best as well as having the mechanics evaluate the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and are able to alert you to any items that may need to be replaced in the near future or those that are already damaged beyond repair.
MD Auto Care in Golden Square are qualified to manage air conditioning repairs, services and regas on most makes and models (AU37017) .
Air Conditioning FAQ's
A car air conditioning system can be classified into four basic parts - a compressor (Pump driven by the engine,) which compresses and circulate gas, a radiator like unit known as a condenser to redistribute heat and condense gas to a liquid, the evaporator (a type of heat exchanger) to remove heat from the car and remove moisture from refrigerant and an expansion device known as an orifice tube or a thermal expansion valve (TXV), (dependent on the type of A/C system used).
Your car air conditioning is designed to remove the heat from the air within the interior of the car and expell it to the outside, 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 happens during a car air conditioning service?
A typical air conditioner service may include
Air vent temperature test
- Confirm condenser temperature ok
- Check suction line temperature ok
- Check correct drive belt & pulley operation
- Check correct operation of thermostats and valves
- Confirm condenser fins are clean
- Ensure adequate condition of of components and hoses
- Evacuation and recharge of refrigerant (where required)
- System line and component inspection with electronic tester
Why do I need a car air conditioner system service?
Avoiding compressor seizure is achieved by checking or changing the oil level in the refrigerant. When the air filters are jammed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to fail to work completely. As well as inhibiting air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
A vehicle air conditioner needs to be checked for problems yearly for any signs of breakdown of the connections, hoses and seals to ensure refrigerant is not leaking over time. Regular service of 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 conditioning is designed to remove the heat from the air within the interior of the car then expell it to the outside, 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.
Even though it operates much like a domestic refrigerator, there are still various significant differences. Seeing as it is mounted on your car, the air conditioning unit is subjected to a large amount of movement and vibration as well as having to function in an outdoor environment.
Being exposed to the elements and very stressful operating temperatures and being expected to run intermittently rather than being 'Always On' can cause breakdown of the hoses, connections and seals. An automotive air conditioner needs to be inspected annually in addition to being fully serviced 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 moist environment can support the development of microbes, bacteria and even fungus growth inside the evaporator core. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. While 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.
MD Auto Care mechanics are able to use special ultrasonic technology to destroy any micro-organisms that may be causing bad 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.
