Car Air Conditioning Service
Cobra Motors are the wise choice to conduct all of your Vehicle Air Conditioner repair, service and inspections in Sunshine North and the surrounding areas.
Todays vehicles are sometimes 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. Automotive air conditioners use refrigerant to remove excess heat from the air in the interior area of the car then expell it to the outside, leaving only cooled or 'conditioned' air behind to be recirculated. It should be considered criticall to conduct an assessment of the condition of the rubber seals for any signs of leaks or wearing which may be causing a loss of refrigerant.
Leaks and evaporation may reduce the refrigerant levels over time meaning your air con system will begin to deteriorate and have to work harder raising the amount of fuel you burn. Even new cars can lose as much as 20% of their refrigerant gas in the first two years.
To allow for this it is strongly recommended that the refrigerant in your Vehicle Air Conditioner is recharged completely within four years of the manufacture date and every two to three years after that.
By getting a yearly Car air conditioning service you can help prevent costly breakdowns now and in the future - and a well serviced Car Air Conditioning system actually saves you money because it expends less fuel.
You should send your vehicle to a qualified workshop such as Cobra Motors on a regular basis to make sure the air conditioning system continues performing at its best as well as having the mechanics go over the condition of the entire car.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection Report with every service and can warn you about any components that may need replacement in the near future or those that are already worn beyond repair.
Cobra Motors in Sunshine North are qualified to perform air conditioning repairs, services and regas on most makes and models (AU37150).
Air Conditioning FAQ's
An automotive air conditioner system is composed of four basic parts - a belt driven pump called a compressor to compress and circulate gas, the condenser to release heat and condense gas to a liquid, an evaporator to withdraw 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 sort of air conditioner system used).
Your car air conditioner system is designed to pull the heat from the air in the interior area of the car then expell it to the exterior, leaving only cooled or 'conditioned' air 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 makes up a car air conditioning service?
A typical air conditioner service may include
Air vent temperature check
- Condenser temperature assessment
- Suction line temperature check
- Adjustments of drive belt and pulley
- Confirm that thermostats and valves are operating correctly
- Ensure condenser fins are free of dirt or debris
- Inspection of components and hoses
- Evacuation and recharge of refrigerant (where required)
- Test system lines and components for leaks with an electronic leak detector
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. When 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 operating completely. Along with impacting air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
A vehicle air conditioner system needs to be examined annually for any signs of problems with the seals, hoses and connections and ensure refrigerant pressure is being maintained over time. Regular service of 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 results in a reduction of fuel expenditure.
Your car air conditioner system is designed to pull the heat from the air in the interior area of the car and carry it to the exterior, leaving only cooled or 'conditioned' air 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 carries out its task in a similar way to a domestic refrigerator, there are still some significant differences. Due to the fact it is mounted on your car, the air conditioning system is subjected to an enormous amount of movement and vibration in addition to having to function outdoors.
Being exposed to the elements and very difficult operating conditions and being run intermittently rather than being 'Always On' can cause failure of the hoses, connections and seals. Your air conditioner ought to be examined once a year in addition to being 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 moist environment can support 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. While modern evaporator units tend to be more efficient they have more fins, meaning an increased capability to trap moisture and allow for micro-organism development.
Cobra Motors mechanics make use of special ultrasonic technology to exterminate any micro-organisms possibly causing any 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.
