Car Air Conditioning Service
Autofix Mechanical Repairs can take charge of all of your Car Air Conditioner repair, servicing or inspections in Kelmscott and the surrounding areas.
Todays cars are very complex and just like the engine, a vehicles air conditioning 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 take the excess heat from the air in the interior of the car then relocate it out of the car, leaving only cooled or 'conditioned' air behind to be recirculated. It should be considered important that the rubber seals are inspected for any signs of leaks or wearing which may be a sign of refrigerant loss.
Evaporation occurring naturally over time or leaks may reduce refrigerant pressure meaning your air con system will begin to deteriorate and have to work harder raising the amount of fuel you burn. Even new cars can lose as much as twenty percent of their refrigerant gas in the first 2 years.
To compensate for this issue it is strongly recommended that the refrigerant in your Vehicle Air Conditioning system is refilled completely within four years of the manufacture date and every two to three years after that.
Getting your car's air conditioning serviced annually means you generally assist prevention of costly breakdowns now and in the future - and a well serviced Automotive Air Conditioner system actually saves you money because it results in a reduction of fuel consumed.
You should take your vehicle to a qualified workshop such as Autofix Mechanical Repairs on a regular basis to ensure the air conditioner system continues performing efficiently as well as having the mechanics go over the condition of the entire car.
Repco Authorised Car Service mechanics perform a 65 point safety check with every service and are usually able to provide a warning about any components that may need replacement in the near future or those that are already worn beyond repair.
Autofix Mechanical Repairs in Kelmscott are qualified to carry out air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
A car air conditioning system can be broken down to four basic parts - a belt driven pump called a compressor to compress and circulate gas, a radiator like unit called a condenser to redistribute heat and condense gas to a liquid, a heat exchanger called an evaporator to exhaust the heat from the car and dehumidify refrigerant and an expansion device usually an orifice tube or a thermal expansion valve (TXV), (subject to the kind of air conditioner system used).
An automotive air conditioner is designed to withdraw heat from the air within the inside of the vehicle then relocate it outside, 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 does a car air conditioning service involve?
A typical air conditioner service may include
Air vent temperature assessment
- Evaluate condenser temperature
- Suction line temperature test
- Check correct drive belt & pulley operation
- Check operation of valves and thermostats
- Ensure condenser fins are free of dirt or debris
- Assess condition of of hoses and components
- Evacuation and recharge of refrigerant (where required)
- Use electronic leak detector to ensure no system lines and components leak
Why do I need a car air conditioner system service?
Compressor seizure can be avoided 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 stop functioning altogether. As well as reducing air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
Your car air conditioner must be examined annually for any signs of issues with the seals, hoses and connections and ensure refrigerant is not leaking 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.
An automotive air conditioner is designed to withdraw heat from the air within the inside of the vehicle and expell it outside, 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 functions much like a domestic refrigerator, there are a few crucial differences. Seeing how it is mounted on your car, the air conditioner is subjected to an extensive amount of movement and vibration in addition to functioning in an outdoor environment.
Being exposed to the elements and very difficult operating conditions and being expected to function intermittently rather than being 'Always On' can cause decay of the seals, hoses and connections. A car air conditioner should be examined once a year while being 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 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. Newer type evaporator units tend to be more efficient, yet have increased capability to trap moisture and allow for micro-organism development.
Autofix Mechanical Repairs mechanics have access to specialist ultrasonic technology to destroy any micro-organisms that may be causing 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.
