Car Air Conditioning Service
Christmas trading hours: Col Harrison Automotive will be closed on Christmas eve December 24 and public holidays December 25-26 and January 1. Schedule your car service online to ensure trouble free motoring during holiday season!
Col Harrison Automotive are licensed to conduct all of your Vehicle Air Conditioner inspections, repair or servicing in West Ryde and the surrounding areas.
Todays cars are quite complex and just like the engine, servicing your car's air conditioner regularly is very important.
Don’t Melt In Your Car
Send the heat packing. Your air conditioner system uses refrigerant to withdraw heat from the air in the vehicle and move it outside, leaving only cooled or 'conditioned' air behind to be redistributed. Therefore it should be considered essential that the rubber seals are appraised for any signs of leaks or weakness which may indicate a loss of refrigerant.
If refrigerant starts to evaporate or leak 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 around twenty percent of their refrigerant gas in the first two years.
To perform in top condition it is strongly recommended that the refrigerant in your Car Air Conditioner is refilled 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 may assist protection from costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioner actually saves you money because it results in a reduction of fuel being used up.
You ought to bring your vehicle to a qualified workshop such as Col Harrison Automotive on a regular basis to make sure the air conditioning system continues performing in optimum conditon as well as having the mechanics advise you on the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 point vehicle inspection report with every service and are usually able to give you a heads up about any items that may need renewal in the near future or those that are already worn beyond repair.
Col Harrison Automotive in West Ryde are qualified to take care of air conditioning repairs, services and regas on most makes and models (AU10851).
Air Conditioning FAQ's
An automotive air conditioner system can be classified into four basic parts - the compressor, a belt driven pump to compress and circulate 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 dehumidify refrigerant and an expansion device known as an orifice tube or a thermal expansion valve (TXV), (subject to the sort of a/c system used).
Your air conditioner system is designed to withdraw the heat from the air in the inside of the car and move it outside, 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 does a car air conditioner service consist of?
A typical air conditioner service may include
Evaluate air vent temperature
- Check condenser temperature is correct
- Check suction line temperature is correct
- Drive belt and pulley adjustment
- Confirm correct operation of valves and thermostats
- Validate cleanliness of the condenser fins
- Confirm good condition of of components and hoses
- Evacuation and recharge of refrigerant (where required)
- Use electronic leak detector to ensure no system lines and components leak
Why do I need a car air conditioner system service?
Seizure of the compressor can be prevented by checking or changing the oil level in the refrigerant. Air filters clogged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to fail to function altogether. In addition to inhibiting air conditioner performance, dirty air filters can cause all kinds of health problems too.
Your automotive air conditioner system needs to be checked for problems once a year for any signs of breakdown in the connections, seals and hoses to make sure too much regfrigerant is not being lost over time. Regular service of your automotive 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 minimises fuel consumed.
Your air conditioner system is designed to withdraw the heat from the air in the inside of the car and expell it outside, 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 carries out its task much like a domestic refrigerator, there are some significant differences. Due to the fact it is mounted on your car, the air conditioning unit is subject to a sizable amount of movement and vibration as well as functioning outdoors.
Being exposed to the mercy of the elements and very intense operating temperatures and being expected to operate intermittently rather than being 'Always On' can have a detrimental effect on the connections, hoses and seals. Your car air conditioning system must be examined annually 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 moist environment. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. Although modern evaporator units may be more efficient, having more fins means they are often more likely to trap moisture allowing microorganism growth.
Col Harrison Automotive mechanics make use of special ultrasonic technology to eliminate 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.
