Car Air Conditioning Service
LeFevre Auto Repairs can perform all of your Automotive Air Conditioner repairs, inspections or servicing in Osborne and the surrounding areas.
Modern cars are complex and just like the engine, your vehicles air conditioner system 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 system uses refrigerant to extract heat from the air in the interior of the vehicle and send it out of the vehicle, leaving only cooled or 'conditioned' air to be redistributed. Therefore it should be considered crucial to study the condition of the rubber seals for any signs of leaks or fractures which could indicate a loss of refrigerant.
Leaking refrigerant or low refrigerant due to evaporation means 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.
For optimum performance it is strongly recommended that the refrigerant in your Car Air Conditioner system is refilled completely within four years of the manufacture date and every two to three years after that.
A yearly car air conditioning service means you can assist prevention of costly breakdowns now and in the future - and a well serviced Automotive Air Conditioning system actually saves you money because it reduces your overall fuel usage.
You should drop off your vehicle to a qualified workshop such as LeFevre Auto Repairs regularly to make sure the air conditioning system continues performing efficiently as well as having the mechanics appraise the condition of the entire car.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and are often able to give you a heads up about any items that may need replacing in the near future or those that are already damaged beyond repair.
LeFevre Auto Repairs in Osborne are qualified to carry out air conditioning repairs, services and regas on most makes and models (AU17979).
Air Conditioning FAQ's
A car air conditioning system is composed of four basic parts - a pump, driven by a belt and called a compressor (to compress and ciculate gas), a condenser, which behaves similarly to a radiator to remove heat and condense gas to a liquid, an evaporator to extract heat from the car and dehumidify refrigerant and an expansion device either a thermal expansion valve (TXV) or an orifice tube, (depending on the sort of A/C system used).
A vehicle air conditioner system is designed to withdraw the heat from the air in the interior area of the vehicle and send it to the exterior, leaving only cooled or 'conditioned' air behind 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 happens during a car air conditioner service?
A typical air conditioner service may include
Test air vent temperature
- Condenser temperature test
- Suction line temperature evaluation
- Pulley and drive belt adjustment
- Check correct operation of thermostats and valves
- Clean the condenser fins
- Check condition of of components and hoses
- 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?
The oil level in the refrigerant passing through the compressor must be checked or changed to avoid it seizing up. When the air filters are blocked with dirt and bacteria it will affect the performance of the entire system and it can even cause it to fail to work altogether. On top of reducing air conditioner performance, dirty air filters can cause all kinds of health problems too.
Your air conditioning System needs to be examined yearly for any signs of failures in the connections, seals and hoses to make sure there is no leaking of refrigerant over time. Regularly servicing your vehicle air conditioner 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 fuel consumption.
A vehicle air conditioner system is designed to withdraw the heat from the air in the interior area of the vehicle then relocate it to the exterior, leaving only cooled or 'conditioned' air behind 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.
Although it carries out its task in a way similar to a domestic refrigerator, there are also significant differences. As it is mounted on your car, the air conditioning unit is subject to an epic amount of movement and vibration in addition to having to function in an outdoor environment.
Being exposed to the elements and very stressful operating conditions and being run intermittently rather than being 'Always On' can cause breakdown of the connections, seals and hoses. Your car air conditioner should be inspected annually as well as 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 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 may be more efficient but they are often more likely to trap moisture allowing microorganism growth.
LeFevre Auto Repairs mechanics are able to use specialist ultrasonic technology to destroy any micro-organisms that may be the source of bad smells 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.
