Car Air Conditioning Service
Black Widow Automotive have the skills to conduct all of your Automotive Air Conditioner service, repair and inspections in Wallan East and the surrounding areas.
Modern vehicles tend to be quite complex and just like the engine, a vehicles air conditioner system has components that need to be serviced or replaced on a regular basis.
Don’t Melt In Your Car
Send the heat packing. An air conditioner uses refrigerant to remove the heat from the air in the interior area of the car and sending it outside, leaving only cooled or 'conditioned' air behind to be recirculated. It's therefore crucial that the rubber seals are checked for any signs of leaks or decay which may well be allowing 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 increasing the amount of fuel you use. Even new cars can lose approximately 20% of their refrigerant gas in the first two years.
To avoid this happening 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.
Having your car's air conditioning serviced annually means you generally protect against costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioning system actually saves you money because it minimises fuel consumption.
Your car should be brought to a qualified workshop such as Black Widow Automotive on a regular basis to make sure the air conditioning system continues performing as it should as well as having the mechanics assess the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 point safety check with every service and can provide a warning about any components that may need renewing in the near future or those that are already worn beyond repair.
Black Widow Automotive in Wallan East 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 - the compressor, a pump driven by a belt to compress and circulate refrigerant 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 exhaust the heat from the car and dehumidify refrigerant and an expansion device either an orifice tube or a thermal expansion valve (TXV), (dependent on the kind of air-con system used).
Your car air conditioner system is designed to remove the heat from the air in the passenger area of the car and sending it to the outside, 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 is done during a car air conditioner service?
A typical air conditioner service may include
Check air vent temperature
- Check condenser temperature is correct
- Check suction line temperature correct
- Pulley and drive belt adjusted
- Operational check of valves and thermostats
- Check condenser fins are clean
- Ensure adequate condition of of hoses and components
- Evacuation and recharge of refrigerant (where required)
- Leak test system lines and components with an electronic leak detector
Why do I need a car air conditioner system service?
Seizing of the compressor can be prevented by checking or changing the oil in the refrigerant. When the air filters become jammed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit operating completely. As well as degrading air conditioner performance, dirty air filters can cause all kinds of health problems too.
Your vehicle air conditioning system must be inspected annually for any signs of issues with the connections, hoses and seals to ensure too much regfrigerant is not being lost over time. Regularly servicing 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 results in a reduction of fuel usage.
Your car air conditioner system is designed to remove the heat from the air in the passenger area of the car then expell it to the outside, 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.
Although it carries out its task in a way similar to a domestic refrigerator, there are still various crucial differences. Being mounted on your car, the air conditioner is subject to an extensive amount of movement and vibration in addition to operating outdoors.
Being exposed to the elements and very difficult operating conditions and being expected to run occasionally rather than being 'Always On' can cause breakdown of the connections, hoses and seals. Your automotive air conditioning system ought to be inspected annually while being fully 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 moist environment can support the development of microbes, bacteria 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. Although modern evaporator units tend to be more efficient, they have an increased capability to trap moisture and allow for micro-organism development.
Black Widow Automotive mechanics will use specialised ultrasonic technology to ensure the eradication of 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.
