Car Air Conditioning Service
Rodney's Mechanical Repair Centre are the smart choice to perform all of your Vehicle Air Conditioner repair, inspections or servicing in Ringwood and the surrounding areas.
Todays vehicles are quite complex and just like the engine, a typical car 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 conditioning uses refrigerant to extract excess heat from the air inside the car then transfer it out of the car, leaving only cooled or 'conditioned' air behind to be recirculated. Therefore it should be considered criticall to assess the condition of the rubber seals for any signs of leaks or wearing which could be a sign of an ongoing loss of refrigerant.
Reduced levels of refrigerant from evaporation or leaks mean 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 20% of their refrigerant gas within 2 years of purchase.
To perform most efficiently it is strongly recommended that the refrigerant in your Automotive Air Conditioning system is replenished completely within four years of the manufacture date and every two to three years after that.
Getting 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 actually saves you money because it reduces fuel usage.
Your vehicle should be brought to a qualified workshop such as Rodney's Mechanical Repair Centre on a regular basis to make sure the air conditioning system continues performing at its best as well as having the mechanics inspect the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 point safety check with every service and are usually able to give you a heads up about any items that may need renewal in the near future or those that are already damaged beyond repair.
Rodney's Mechanical Repair Centre in Ringwood are qualified to take charge of air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
An automotive air conditioning system can be broken down to four basic parts - a pump, driven by a belt and called a compressor (to compress and ciculate gas), a radiator like unit known as a condenser (to dissipate heat and condense gas to a liquid), the evaporator (a type of heat exchanger) to take the heat from the car and remove moisture from refrigerant and an expansion device which could be an orifice tube or a thermal expansion valve (TXV), (depending on the type of A/C system used).
Your car air conditioner is designed to pull the heat from the air in the interior of the car then transfer it out of the car, leaving only cooled or 'conditioned' air 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 comprises a car air conditioning service?
A typical air conditioner service may include
Check air vent temperature
- Confirm condenser temperature ok
- Check suction line temperature is correct
- Corrections of drive belt and pulley
- Validate correct operation of thermostats and valves
- Validate cleanliness of the condenser fins
- Confirm adequate condition of of components and hoses
- Evacuation and recharge of refrigerant (where required)
- Check system lines and components for leaks with an electronic leak detector
Why do I need a car air conditioner system service?
Checking or changing the oil level in the refrigerant you protect the compressor and stop it from seizing up. Air filters jammed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit working altogether. In addition to inhibiting air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
Your automotive air conditioner system should be checked for problems yearly for any signs of breakdown in the connections, seals and hoses and ensure refrigerant is not leaking over time. Regularly servicing your car 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 the fuel being used.
Your car air conditioner is designed to pull the heat from the air in the interior of the car then exhaust it out of the car, 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.
While it operates much like a domestic refrigerator, there are a couple of crucial differences. Because it is mounted on your car, the air conditioning system is subjected to a considerable amount of movement and vibration as well as functioning in an outdoor environment.
Being exposed to the elements and very diverse operating conditions and being expected to operate intermittently rather than being 'Always On' can cause failure of the seals, hoses and connections. A vehicle air conditioner system must be checked annually as well as being properly 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 evaporator core can become a breeding ground for microbes, bacteria and even fungus due to the damp environment. 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.
Rodney's Mechanical Repair Centre mechanics will use special ultrasonic technology to remove 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.
