Car Air Conditioning Service
Vehicle Tech are the right choice to undertake all of your Vehicle Air Conditioning servicing, repair and inspections in Lilydale and the surrounding areas.
Modern cars are extremely complex and just like the engine, a car 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 system uses refrigerant to extract the excess heat from the air in the interior of the vehicle and carry it outside, leaving only cooled or 'conditioned' air to be recirculated. Therefore it should be considered important that the rubber seals are scrutinised for any signs of leaks or problems 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 increasing your fuel usage. Even new cars can lose around 20% of their refrigerant gas within 2 years of purchase.
To run in optimum condition it is strongly recommended that the refrigerant in your Automotive Air Conditioner is refilled 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 may help protect your system from costly breakdowns now and in the future - and a well serviced Car Air Conditioning system actually saves you money because it results in a reduction of fuel being burned.
Your vehicle should be taken to a qualified workshop such as Vehicle Tech regularly to ensure the air conditioner system continues performing as it should as well as having the mechanics advise you on the condition of the entire car.
Repco Authorised Car Service mechanics perform a 65 point safety check with every service and are able to alert you to any items that may need replacing in the near future or those that are already worn beyond repair.
Vehicle Tech in Lilydale are qualified to perform 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 compressor (Pump driven by the engine,) which compresses and circulates refrigerant gas, a radiator like unit called a condenser to remove heat and condense gas to a liquid, the evaporator (a type of heat exchanger) to exhaust the heat from the car and dehumidify refrigerant and an expansion device called a thermal expansion valve (TXV) or an orifice tube, (dependent on the sort of air-con system used).
An automotive air conditioning is designed to take the heat from the air within the passenger area of the car and carry 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
Air vent temperature assessment
- Condenser temperature test
- Make sure suction line temperature is correct
- Confirm correct drive belt & pulley operation
- Ensure that valves and thermostats are operating correctly
- Undertake cleaning of the condenser fins
- Confirm good condition of of hoses and components
- Evacuation and recharge of refrigerant (where required)
- System line and component evaluation with electronic tester
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. If the air filters are choked with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit operating altogether. In addition to reducing air conditioner performance, dirty air filters can cause all kinds of health problems too.
A car air conditioner system ought to be checked for problems yearly for any signs of issues with the connections, hoses and seals and ensure the refrigerant has not leaked over time. Regular service of your car air conditioner 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 consumption.
An automotive air conditioning is designed to take the heat from the air within 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.
While it operates similarly to a domestic refrigerator, there are various crucial differences. Due to the fact it is mounted on your car, the air conditioning unit is subjected to an enormous amount of movement and vibration in addition to having to perform outdoors.
Being exposed to the elements and very diverse operating conditions and being switched on intermittently rather than being 'Always On' can cause problems on the seals, hoses and connections An automotive air conditioner system must be examined yearly and properly 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 core of the evaporator can become a breeding ground for microbes, bacteria and even fungus due to the moist environment. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. Newer type evaporator units may be more efficient but they are often more likely to trap moisture allowing microorganism growth.
Vehicle Tech mechanics have access to specialist ultrasonic technology to actively target any micro-organisms possibly causing any unpleasant odours or health issues.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.
