Car Air Conditioning Service
Renmark Auto Service are the logical choice to carry out all of your Automotive Air Conditioning repair, servicing and inspections in Renmark and the surrounding areas.
Todays vehicles are extremely 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. Automotive air conditioner systems use refrigerant to remove the heat from the air in the vehicle and move it to the outside, leaving only cooled or 'conditioned' air behind to be redistributed. It is very important to scrutinise the condition of the rubber seals for any signs of leaks or detoriation which may indicate a loss of refrigerant.
When this refrigerant has started to leak or evaporate your air con system will begin to deteriorate and have to work harder meaning more fuel is being consumed. Even new cars can lose approximately 20% of their refrigerant gas within 2 years of purchase.
For optimum performance it is strongly recommended that the refrigerant in your Automotive Air Conditioner is replenished completely within four years of the manufacture date and every two to three years after that.
A yearly car air conditioning service means you often help prevent costly breakdowns now and in the future - and a well serviced Automotive Air Conditioner actually saves you money because it consumes less fuel.
You should drop off your car to a qualified workshop such as Renmark Auto Service on a regular basis to ensure the air conditioner system continues performing efficiently as well as having the mechanics evaluate 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 warn you about any components that may need to be replaced in the near future or those that are already worn beyond repair.
Renmark Auto Service in Renmark are qualified to perform air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
An automotive air conditioning system contains four basic parts - a pump driven by a belt, known as a compressor (to compress and ciculate gas), a radiator like unit called a condenser to redistribute heat and condense gas to a liquid, the evaporator (a type of heat exchanger) to extract heat from the car and dehumidify refrigerant and an expansion device which could be a thermal expansion valve (TXV) or an orifice tube, (dependent on the kind of A/C system used).
An automotive air conditioner system is designed to take the excess heat from the air within the interior of the vehicle and move 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 is included in a car air conditioner service?
A typical air conditioner service may include
Air vent temperature test
- ensure condenser temperature ok
- Suction line temperature inspection
- Adjustments of drive belt and pulley
- Validate correct operation of thermostats and valves
- Cleaning the condenser fins
- Confirm adequate condition of of components and hoses
- Evacuation and recharge of refrigerant (where required)
- System line and component inspection with electronic tester
Why do I need a car air conditioner system service?
The oil level in the refrigerant passing through the compressor must be checked or changed to avoid it seizing up. Should the air filters become plugged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit working completely. Aside from reducing air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
Your vehicle air conditioner system ought to be checked for problems yearly for any signs of problems with the connections, hoses and seals to make sure refrigerant levels have not diminished 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 reduces fuel consumption.
An automotive air conditioner system is designed to take the excess heat from the air within the interior of the vehicle then expell 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.
Even though it carries out its task similarly to a domestic refrigerator, there are still significant differences. Because it is mounted on your car, the air conditioner is subject to an extensive amount of movement and vibration in addition to having to operate in an outdoor environment.
Being exposed to the elements and very intense operating conditions and being expected to function intermittently rather than being 'Always On' can cause issues with the seals, hoses and connections. An air conditioning system must be checked once a year and 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. While modern evaporator units may be more efficient, having more fins means they are often more likely to trap moisture allowing microorganism growth.
Renmark Auto Service mechanics have the capability to use special ultrasonic technology to actively target any micro-organisms that may be causing unpleasant 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.
