Car Air Conditioning Service
Wheeler Automotives are certified to perform all of your Car Air Conditioner inspections, repair or servicing in Maddington and the surrounding areas.
Modern cars are tend to be quite complex and just like the engine, a vehicles 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 pull heat from the air in the car then carry it to the outside, leaving only cooled or 'conditioned' air to be recirculated. Therefore it should be considered essential to examine the condition of the rubber seals for any signs of leaks or wearing which could be a sign of a loss of refrigerant.
Reduced levels of refrigerant from leaks or evaporation mean 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 in the first 2 years.
To compensate for this problem it is strongly recommended that the refrigerant in your Vehicle Air Conditioning system 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 yearly means you help protect the air con from costly breakdowns now and in the future - and a well serviced Car Air Conditioner actually saves you money because it minimises fuel consumption.
You should send your vehicle to a qualified workshop such as Wheeler Automotives on a regular basis to ensure the air conditioner system continues performing at its best as well as having the mechanics go over the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and can alert you to any items that may need to be renewed in the near future or those that are already damaged beyond repair.
Wheeler Automotives in Maddington can arrange your air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
A car air conditioning system is made up of of four basic parts - a compressor (Pump driven by the engine,) which compresses and circulates refrigerant gas, a condenser, which behaves similarly to a radiator to dissipate heat and condense gas to a liquid, a heat exchanger called an evaporator to exhaust the heat from the car and remove moisture from refrigerant and an expansion device called a thermal expansion valve (TXV) or an orifice tube, (dependent on the kind of air-con system used).
Your car air conditioning system is designed to remove heat from the air within the interior of the vehicle then carry it to the exterior, 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 is involved in a car air conditioning service?
A typical air conditioner service may include
Assess air vent temperature
- Check condenser temperature
- Ensure suction line temperature correct
- Pulley and drive belt adjustment
- Check that valves and thermostats are operating correctly
- Cleaning of the condenser fins
- Inspect condition of of hoses and components
- Evacuation and recharge of refrigerant (where required)
- Electronically test 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 save it from seizing up. If the air filters are obstructed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit functioning altogether. In addition to inhibiting air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
Your automotive air conditioner system must be examined once a year for any signs of breakdown of the hoses, connections and seals and confirm the refrigerant has not leaked over time. Regular service of your vehicle 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 reduces the amount of fuel being burned.
Your car air conditioning system is designed to remove heat from the air within the interior of the vehicle then send it to the exterior, 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 functions similarly to a domestic refrigerator, there are still a few significant differences. Because it is mounted on your car, the air conditioning unit is subjected to a huge amount of movement and vibration in addition to operating in an outdoor environment.
Being exposed to the elements and very diverse operating conditions and being used intermittently rather than being 'Always On' can cause breakdown of the seals, hoses and connections. A vehicle air conditioner ought to be examined once a year in addition to being properly 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 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. Modern evaporator units tend to be more efficient, but more fins equals increased capability to trap moisture and allow for micro-organism development.
Wheeler Automotives mechanics will use specialist ultrasonic technology to ensure the removal of any micro-organisms that may be causing bad 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.
