Car Air Conditioning Service
Dufty Automotive Services are well placed to manage all of your Vehicle Air Conditioning servicing, repair or inspections in Leumeah and the surrounding areas.
Todays vehicles are sometimes complex and just like the engine, an automotive 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. Your car air conditioner uses refrigerant to remove heat from the air in the passenger area of the car then move it to the exterior, leaving only cooled or 'conditioned' air behind to be redistributed. It is criticall that the rubber seals are appraised for any signs of leaks or wear which may be contributing to a loss of refrigerant.
Evaporation or leaking of thisrefrigerant 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 allow 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.
By getting a Car air conditioning service every twelve months you often help protect the system against costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioning system actually saves you money because it consumes less fuel.
You should send your car to a qualified workshop such as Dufty Automotive Services regularly to make sure the air conditioning system continues performing at its best as well as having the mechanics assess 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 give you a heads up about any components that may need to be replaced in the near future or those that are already damaged beyond repair.
Dufty Automotive Services in Leumeah are qualified to manage air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
An automotive air conditioning system is composed of four basic parts - the compressor, a belt driven pump to compress and circulate gas, the condenser to release heat and condense gas to a liquid, the evaporator (a type of heat exchanger) to take the heat from the car and dehumidify refrigerant and an expansion device either a thermal expansion valve (TXV) or an orifice tube, (dependent on the sort of air-con system used).
Your car air conditioning system is designed to withdraw the heat from the air within the inside of the car then move it outside, leaving only cooled or 'conditioned' air behind to be recirculated. 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 conditioner service usually consist of?
A typical air conditioner service may include
Inspect air vent temperature
- Assess condenser temperature
- Ensure suction line temperature correct
- Drive belt and pulley adjustment
- Operational check of valves and thermostats
- Validate condenser fins are clean
- Confirm good condition of of components and hoses
- Evacuation and recharge of refrigerant (where required)
- Electronically inspect system lines and components for leaks
Why do I need a car air conditioner system service?
Preventing compressor seizure is achieved by checking or changing the oil level in the refrigerant. Air filters plugged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to give out altogether. On top of inhibiting air conditioner performance, dirty air filters can cause all kinds of health problems too.
An air conditioning system ought to be examined once a year for any signs of problems with the hoses, connections and seals to ensure there is no leaking of refrigerant over time. Regularly servicing your automotive 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 minimises fuel consumption.
Your car air conditioning system is designed to withdraw the heat from the air within the inside of the car then carry it outside, leaving only cooled or 'conditioned' air behind 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.
Even though it operates similarly to a domestic refrigerator, there are still a few significant differences. As it is mounted on your car, the air conditioning system is subject to a tremendous amount of movement and vibration as well as having to function outdoors.
Being exposed to the elements and very diverse operating temperatures and being expected to run intermittently rather than being 'Always On' can cause decay of the seals, hoses and connections. A vehicle air conditioner must be checked once a year while 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 damp environment can promote the development of bacteria, microbes 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. Modern evaporator units may be more efficient but they are often more likely to trap moisture allowing microorganism growth.
Dufty Automotive Services mechanics can use special ultrasonic technology to exterminate any micro-organisms that may be causing bad 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.
