Car Air Conditioning Service
Lismore Automotive Service are the right choice to conduct all of your Car Air Conditioning repairs, servicing or inspections in Lismore and the surrounding areas.
Todays vehicles are very complex and just like the engine, a vehicles air conditioner has components that need to be serviced or replaced on a regular basis.
Don’t Melt In Your Car
Send the heat packing. Car air conditioning uses refrigerant to take the heat from the air in the inside of the vehicle then carry it to the exterior, leaving only cooled or 'conditioned' air behind to be redistributed. Therefore it should be considered essential to scrutinise the condition of the rubber seals for any signs of leaks or detoriation which may point to a loss of refrigerant.
Reduced levels of refrigerant from evaporation or leaks mean your air con system will begin to deteriorate and have to work harder with a resulting increase in fuel being used up. Even new cars can lose around 20% of their refrigerant gas within two years of purchase.
To compensate for 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.
A yearly car air conditioning service means you generally protect against costly breakdowns now and in the future - and a well serviced Automotive Air Conditioning system actually saves you money because it uses less fuel.
You should drop off your car to a qualified workshop such as Lismore Automotive Service on a regular basis to make sure the air conditioning system continues performing at its best as well as having the mechanics appraise the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and can provide a warning about any items that may need replacing in the near future or those that are already worn beyond repair.
Lismore Automotive Service in Lismore are qualified to conduct air conditioning repairs, services and regas on most makes and models (AU10449).
Air Conditioning FAQ's
A car air conditioning system can be broken down to four basic parts - a compressor (Pump driven by the engine,) which compresses and circulate gas, a radiator like unit called a condenser to release heat and condense gas to a liquid, an evaporator to withdraw heat from the car and dehumidify refrigerant and an expansion device known as a thermal expansion valve (TXV) or an orifice tube, (depending on the sort of air conditioner system used).
A car air conditioning is designed to extract excess heat from the air in the interior of the vehicle then carry it out of the car, 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 takes place in a a car air conditioning service?
A typical air conditioner service may include
Assess air vent temperature
- Condenser temperature test
- Suction line temperature check
- Check operation of drive belt & pulley ok
- Check that thermostats and valves are operating correctly
- Cleaning the condenser fins
- Confirm good condition of of components and hoses
- Evacuation and recharge of refrigerant (where required)
- Use electronic leak detector to 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 prevent it seizing up. Should the air filters be 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. Along with inhibiting air conditioner performance, dirty air filters can cause all kinds of health problems too.
A vehicle air conditioning system needs to be checked for problems yearly for any signs of failure of the connections, hoses and seals and confirm refrigerant levels are being maintained over time. Regularly servicing your vehicle 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 reduces fuel expenditure.
A car air conditioning is designed to extract excess heat from the air in the interior of the vehicle and transfer it out of the car, 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 carries out its task in a similar way to a domestic refrigerator, there are still a few significant differences. Due to the fact it is mounted on your car, the air conditioning system is subjected to a tremendous amount of movement and vibration as well as functioning in an outdoor environment.
Being exposed to the elements and very difficult operating conditions and being expected to operate occasionally rather than being 'Always On' can cause decay of the connections, seals and hoses. An automotive air conditioner ought to be checked yearly 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 core of the evaporator 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. While modern evaporator units tend to be more efficient, the addition of extra fins leads to an increased ability to trap moisture, allowing micro-organism development.
Lismore Automotive Service mechanics have the capability to use specialist ultrasonic technology to ensure the extermination of any micro-organisms that may cause 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.
