Car Air Conditioning Service
Schwarz Motor Repairs are well placed to carry out all of your Automotive Air Conditioner inspections, repair and servicing in Loxton and the surrounding areas.
Todays cars are sometimes complex and just like the engine, a vehicles air conditioner system has elements that need to be serviced or replaced on a regular basis.
Don’t Melt In Your Car
Send the heat packing. Your air conditioner system uses refrigerant to absorb heat from the air inside the vehicle then exhaust it to the exterior, leaving only cooled or 'conditioned' air behind to be recirculated. It is therefore essential that the rubber seals are scrutinised for any signs of leaks or detoriation which may be an indication of refrigerant loss.
Refrigerant can leak or evaporate over time meaning your air con system will begin to deteriorate and have to work harder which means you burn more fuel. Even new cars can lose as much as 20% of their refrigerant gas in the first two years.
To avoid this situation 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 an annual Car air conditioner service you help protect the air con from costly breakdowns now and in the future - and a well serviced Car Air Conditioner actually saves you money because it lowers your fuel consumption.
You should drop off your vehicle to a qualified workshop such as Schwarz Motor Repairs on a regular basis to make sure the air conditioning system continues performing efficiently as well as having the mechanics review the condition of the entire car.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and can provide a warning about any components that may need replacement in the near future or those that are already damaged beyond repair.
Schwarz Motor Repairs in Loxton are qualified to perform air conditioning repairs, services and regas on most makes and models (AU31293).
Air Conditioning FAQ's
A car air conditioning system can be classified into four basic parts - a pump, driven by a belt, called a compressor (to compress and ciculate refrigerant gas), a condenser, which behaves similarly to a radiator to redistribute heat and condense gas to a liquid, an evaporator to remove heat from the car and dehumidify refrigerant and an expansion device which could be an orifice tube or a thermal expansion valve (TXV), (depending on the sort of A/C system used).
A vehicle air conditioning system is designed to take the excess heat from the air within the interior of the vehicle then exhaust 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 makes up a car air conditioning service?
A typical air conditioner service may include
Air vent temperature test
- Condenser temperature test
- Ensure suction line temperature correct
- Confirm correct drive belt & pulley operation
- Ensure correct operation of thermostats and valves
- Condenser fins cleaned
- Ensure adequate condition of of hoses and components
- 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?
Seizing of the compressor can be prevented by checking or changing the oil in the refrigerant. Air filters plugged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to stop working altogether. On top of reducing air conditioner performance, dirty air filters can cause all kinds of health problems too.
Your car air conditioner needs to be checked for problems annually for any signs of decay of the connections, hoses and seals and confirm refrigerant levels have not diminished over time. Regularly servicing your car air conditioner 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.
A vehicle air conditioning system is designed to take the excess heat from the air within the interior of the vehicle and send 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.
Although it operates in a similar way to a domestic refrigerator, there are still some significant differences. Being mounted on your car, the air conditioning unit is subjected to a prodigious amount of movement and vibration in addition to functioning in an outdoor environment.
Being exposed to the mercy of the elements and very extreme operating conditions and being operated intermittently rather than being 'Always On' can cause failure of the connections, hoses and seals. A car air conditioner system needs to be examined once a year in addition to being properly 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 damp environment inside the evaporator core can support the development of microbes, bacteria and even fungus growth. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. Modern evaporator units tend to be more efficient, but more fins equals increased ability to trap moisture allowing micro-organism development.
Schwarz Motor Repairs mechanics make use of specialised ultrasonic technology to ensure the removal of any micro-organisms possibly causing any 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.
