Urangan Service Centre are well placed to take care of all of your Automotive Air Conditioning Re-gas, Repairs, Servicing and Inspection needs
Your vehicle should be taken to a reputable workshop such as Urangan Service Centre 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 whole vehicle.
Repco Authorised Service mechanics perform a 65 point Vehicle Inspection with every service and are able to give you a heads up about any components that may need renewing in the near future or those that are already worn beyond repair.
Urangan Service Centre can arrange automotive air conditioning service with a licenced technician in and around Urangan and the surrounding areas.
Air Conditioning FAQ's
Car air conditioners - how does it happen?
An automotive air conditioning system is made up of four basic parts - a compressor (Pump driven by the engine,) which compresses and circulate gas, a condenser, which behaves similarly to a radiator to remove heat and condense gas to a liquid, an expansion device, which could be a thermal expansion valve (TXV) or an orifice tube (depending on the type of air conditioner system used). Systems using orifice tubes also have an accumulator before the compressor to remove moisture from the refrigerant while TXV systems have a receiver-dryer before the evaporator to perform the same crucial task. Both the accumulator and receiver-drier are also used to store refrigerant.
Vehicle air conditioning is designed to pull the heat from the air within the interior area of the vehicle and transfer it out of the vehicle, leaving only cooled or 'conditioned' air to be recirculated. Hot air is passed across a gas filled evaporator, where the heat is easily absorbed by the refrigerant (in gas form), effectively removing the heat from the air in the car.
The now heated gas is pulled through the compressor where it is further heated (via compression). The next stage involves the refrigerant being forced through the condenser to quickly extract the heat from the refrigerant. The refrigerant, now condensed to a liquid, then moves through the expansion device (either a TXV or Orifice tube), which regulates the flow of refrigerant going to the evaporator, changing the high-pressure liquid to a low-pressure mist (gas). A fan blowing over the cold fins of the evaporator produces the cold air being blown into the car and the entire process then begins all over again.
What is involved in a car air conditioning service?
A typical air conditioner service may include some of the following items;
Make sure air vent temperature is correct
- condenser temperature check
- Confirm suction line temperature ok
- Validate correct drive belt & pulley operation
- Ensure that thermostats and valves are operating correctly
- Undertake cleaning of the condenser fins
- Evaluate condition of hoses and components
- Evacuation and recharge of refrigerant (where required)
- Use electronic leak detector to check system lines and components for leaks
Why do I need a car air conditioner system service?
By checking or changing the oil level in the refrigerant you protect the compressor and avoid it seizing up. Air filters clogged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to stop functioning altogether. In addition to inhibiting air conditioner performance, dirty air filters can cause all kinds of health problems too.
Your air conditioning System must be examined annually for any signs of issues with the seals, hoses and connections and ensure refrigerant levels are being maintained over time. Regular service of your 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 usage.
Why does the car air conditioner need to be serviced?
Vehicle air conditioning is designed to pull the heat from the air within the interior area of the vehicle out of the vehicle, 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.
Being exposed to the elements and very diverse operating temperatures and being expected to operate intermittently rather than being 'Always On' can cause failure of the connections, hoses and seals. A vehicle air conditioner should be examined on a regular basis 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 and intermittent use can cause seals to dry and crack, allowing them to leak. Even without leaks, the gas in a car air conditioning system will eventually begin to degrade or evaporate over time and should be recharged where required to keep the air con system in peak running condition.
Can I service my own Air Conditioner?
Only qualified mechanics with the appropriate training should attempt to service a car air conditioner. Specific licences are required to be able to service or repair some types of car air conditioning systems, especially where regas (recharging of the refrigerant) is concerned. Strict guidelines and procedures must be adhered to when handling certain refrigerants, 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, to avoid seriously damaging the system.
Urangan Service Centre can arrange Air Conditioning Service with a Licenced Technician. You can find out more about licensing on the Australian Refrigeration Council (ARC) Website.
What is causing the bad smell in car air conditioning?systems?
The damp environment inside the evaporator core can promote 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. While modern evaporator units tend to be more efficient, they have an increased capability to trap moisture and allow for micro-organism development.
Urangan Service Centre mechanics will use specialised ultrasonic technology to eradicate any micro-organisms that may be the source of 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.
