Car Air Conditioning Service
D & D Mechanical & 4WD are qualified to perform all of your Car Air Conditioning servicing, repair and inspections in Goolwa and the surrounding areas.
Modern vehicles are complex and just like the engine, a typical automotive 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. Car air conditioning systems use refrigerant to extract the heat from the air inside the car and send it to the exterior, leaving only cooled or 'conditioned' air behind to be recirculated. It should be considered important that the rubber seals are checked for any signs of leaks or decay which could indicate a continuing loss of refrigerant.
Leakage of refrigerant and evaporation mean that your air con system will begin to deteriorate and have to work harder increasing the amount of fuel you burn. Even new cars can lose as much as twenty percent of their refrigerant gas within two years of purchase.
To compensate for this situation it is strongly recommended that the refrigerant in your Automotive Air Conditioner is recharged completely within four years of the manufacture date and every two to three years after that.
Having your car's air conditioning serviced once a year means you generally protect against costly breakdowns now and in the future - and a well serviced Car Air Conditioner system actually saves you money because it reduces fuel usage.
Your car should be inspected by a qualified workshop such as D & D Mechanical & 4WD (AU26921) regularly to make sure the air conditioning system continues performing in optimum conditon as well as having the mechanics examine the condition of the entire car.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and are usually able to provide a warning about any items that may need replacing in the near future or those that are already damaged beyond repair.
D & D Mechanical & 4WD in Goolwa are qualified to carry out air conditioning repairs, services and regas on most makes and models (AU26921).
Air Conditioning FAQ's
A car air conditioner system contains four basic parts - the compressor, a belt driven pump to compress and circulate refrigerant gas, a radiator like unit called a condenser (redistributes heat and condenses gas to a liquid), the evaporator (a type of heat exchanger) to remove heat from the car and remove moisture from refrigerant and an expansion device which could be a thermal expansion valve (TXV) or an orifice tube, (subject to the kind of air-con system used).
Your car air conditioner is designed to withdraw the heat from the air in the passenger area of the car and send it out of the car, 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 is done during a car air conditioner service?
A typical air conditioner service may include
Evaluate air vent temperature
- Condenser temperature test
- Suction line temperature assessment
- Drive belt and pulley correction
- Ensure correct operation of thermostats and valves
- Confirm condenser fins are free of dirt or debris
- Inspect condition of of hoses and components
- Evacuation and recharge of refrigerant (where required)
- Use electronic leak detector to asses 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. If the air filters are plugged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to cease functioning altogether. On top of impacting air conditioner performance, dirty air filters can cause all kinds of health problems too.
An automotive air conditioning system must be inspected annually for any signs of decay of the connections, hoses and seals to make sure there is no reduction of refrigerant over time. Regular service of 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.
Your car air conditioner is designed to withdraw the heat from the air in the passenger area of the car and transfer it out of the car, 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.
Even though it functions in a similar way to a domestic refrigerator, there are a few crucial differences. Being mounted on your car, the air conditioning system is subjected to a considerable amount of movement and vibration as well as operating outdoors.
Being exposed to the elements and very stressful operating temperatures and being switched on occasionally rather than being 'Always On' can cause issues with the hoses, connections and seals. A car air conditioning system must be inspected annually and 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. Although modern evaporator units may be more efficient, having more fins means they are often more likely to trap moisture allowing microorganism growth.
D & D Mechanical & 4WD mechanics are able to use specialised ultrasonic technology to kill any micro-organisms that may cause bad smells 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.
