Car Air Conditioning Service
Southern Highlands Service Centre have the skills to perform all of your Car Air Conditioner repair, service and inspections in Mittagong and the surrounding areas.
Todays cars can be very complex and just like the engine, a vehicles air conditioner has components that need to be serviced or replaced on a regular basis.
Don’t Melt In Your Car
Send the heat packing. Your car air conditioner uses refrigerant to extract excess heat from the air within the interior of the vehicle and expell it out of the car, leaving only cooled or 'conditioned' air behind to be redistributed. It is crucial that the rubber seals are inspected for any signs of leaks or decline which may be a sign of refrigerant loss.
Low refrigerant due to leaks or evaporation means your air con system will begin to deteriorate and have to work harder with a resulting increase in fuel consumed. Even new cars can lose as much as twenty percent of their refrigerant gas in the first 2 years.
To avoid this issue it is strongly recommended that the refrigerant in your Vehicle Air Conditioning system is recharged 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 can assist prevention of costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioner actually saves you money because it reduces the amount of fuel being burned.
Your vehicle should be brought to a qualified workshop such as Southern Highlands Service Centre regularly to make sure the air conditioning system continues performing in optimum conditon as well as having the mechanics assess the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 point safety check with every service and can alert you to any items that may need replacement in the near future or those that are already worn beyond repair.
Southern Highlands Service Centre in Mittagong are qualified to take charge of air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
A car air conditioning system contains four basic parts - a pump, driven by a belt and known as a compressor (to compress and ciculate refrigerant gas), a radiator like unit called a condenser (removes heat and condenses gas to a liquid), a heat exchanger called an evaporator to extract heat from the car and remove moisture from refrigerant and an expansion device usually a thermal expansion valve (TXV) or an orifice tube, (depending on the type of A/C system used).
A vehicle air conditioner is designed to pull heat from the air in the car and expell 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 makes up a car air conditioner service?
A typical air conditioner service may include
Check air vent temperature
- Check condenser temperature is correct
- Check suction line temperature correct
- Drive belt and pulley adjusted
- Confirm correct operation of valves and thermostats
- Ensure condenser fins are clean
- Evaluate 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?
By checking or changing the oil level in the refrigerant you protect the compressor and prevent it seizing up. When the air filters are obstructed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit altogether. As well as impacting air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
A vehicle air conditioner system ought to be checked for problems once a year for any signs of breakdown of the connections, hoses and seals and ensure too much regfrigerant is not being lost over time. Regular servicing your vehicle 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 reduces your overall fuel usage.
A vehicle air conditioner is designed to pull heat from the air in the car then transfer 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 functions much like a domestic refrigerator, there are still a few significant differences. Because it is mounted on your car, the air conditioning unit is subject to a tremendous amount of movement and vibration as well as performing in an outdoor environment.
Being exposed to the elements and very intense operating conditions and being in use intermittently rather than being 'Always On' can cause problems on the hoses, connections and seals. Your air conditioning System needs to be checked annually as well as being serviced every 24 months 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 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. Modern evaporator units tend to be more efficient, but more fins equals increased ability to trap moisture allowing micro-organism development.
Southern Highlands Service Centre mechanics make use of specialist ultrasonic technology to ensure elimination of 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.
