Car Air Conditioning Service
Chris`s Mechanical are qualified to take care of all of your Car Air Conditioner repair, servicing or inspections in Hawker and the surrounding areas.
Todays vehicles are quite complex and just like the engine, a vehicles air conditioning system has elements that need to be serviced or replaced on a regular basis.
Don’t Melt In Your Car
Send the heat packing. An air conditioner system uses refrigerant to extract the excess heat from the air in the car and exhaust it outside, leaving only cooled or 'conditioned' air to be redistributed. It's therefore crucial that the rubber seals are checked for any signs of leaks or detoriation which may contribute to an ongoing loss of refrigerant.
Losing refrigerant through evaporation or leakage generally means your air con system will begin to deteriorate and have to work harder raising your overall fuel usage. Even new cars can lose as much as 20% of their refrigerant gas within two years of purchase.
To address this situation it is strongly recommended that the refrigerant in your Automotive Air Conditioner is recharged completely within four years of the manufacture date and every two to three years after that.
A car air conditioning service every 12 months means you can assist protection from costly breakdowns now and in the future - and a well serviced Automotive Air Conditioner actually saves you money because it minimises fuel consumption.
You should drop off your car to a qualified workshop such as Chris`s Mechanical on a regular basis to make sure the air conditioning system continues performing in top conditon as well as having the mechanics check the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 point safety check with every service and provide a heads up about any components that may need renewal in the near future or those that are already damaged beyond repair.
Chris`s Mechanical in Hawker are qualified to manage air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
A car air conditioner system could be seen as having four basic parts - a belt driven pump known as a compressor to compress and circulate refrigerant gas, a radiator like unit known as a condenser to remove heat and condense gas to a liquid, an evaporator to take the heat from the car and remove moisture from refrigerant and an expansion device either an orifice tube or a thermal expansion valve (TXV), (depending on the type of A/C system used).
Your air conditioner is designed to pull the heat from the air in the vehicle and exhaust 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 makes up a car air conditioning service?
A typical air conditioner service may include
Validate that air vent temperature is correct
- Ensure condenser temperature correct
- Test suction line temperature
- Validate correct drive belt & pulley operation
- Ensure correct operation of valves and thermostats
- Undertake cleaning the fins of the condesner
- Confirm good condition of of hoses and components
- Evacuation and recharge of refrigerant (where required)
- Use electronic leak detector to ensure no components or system lines leak
Why do I need a car air conditioner system service?
Compressor seizure can be avoided by checking or changing the oil level in the refrigerant. Air filters plugged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to cease to work altogether. As well as degrading air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
A car air conditioner should be inspected annually for any signs of problems with the connections, seals and hoses and confirm there is no leaking of refrigerant over time. Regular service of 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 reduces fuel usage.
Your air conditioner is designed to pull the heat from the air in the vehicle and move 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.
Even though it operates in a way similar to a domestic refrigerator, there are several significant differences. Being mounted on your car, the air conditioning system is subject to a gigantic amount of movement and vibration in addition to operating in an outdoor environment.
Being exposed to the elements and very harsh operating conditions and being operated occasionally rather than being 'Always On' can cause decay of the seals, hoses and connections. An automotive air conditioning system ought to be examined annually in addition to 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 damp environment inside the evaporator core can support the development of bacteria, microbes and even fungus growth. 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.
Chris`s Mechanical mechanics are able to use specialised ultrasonic technology to deal with any micro-organisms that may be causing bad 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.
