Car Air Conditioning Service
Rawson Motors can carry out all of your Automotive Air Conditioner repairs, inspections and servicing in Officer and the surrounding areas.
Modern cars are very 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. Car air conditioning uses refrigerant to pull the heat from the air within the interior area of the car and exhaust it outside, leaving only cooled or 'conditioned' air behind to be recirculated. Therefore it should be considered essential to conduct an inspection of the condition of the rubber seals for any signs of leaks or cracks which could be causing a loss of refrigerant.
Evaporation or leaking of thisrefrigerant means your air con system will begin to deteriorate and have to work harder with a resulting increase in fuel usage. Even new cars can lose around twenty percent of their refrigerant gas within 2 years of purchase.
To compensate for this issue it is strongly recommended that the refrigerant in your Vehicle Air Conditioner system is recharged completely within four years of the manufacture date and every two to three years after that.
Getting your car's air conditioning serviced yearly means you often help prevent costly breakdowns now and in the future - and a well serviced Automotive Air Conditioner system actually saves you money because it minimises fuel consumption.
You should drop off your vehicle to a qualified workshop such as Rawson Motors on a regular basis to ensure the air conditioner system continues performing correctly 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 are usually able to give you a warning about any items that may need renewing in the near future or those that are already damaged beyond repair.
Rawson Motors in Officer are qualified to undertake air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
A car air conditioning system is made up of of four basic parts - a compressor (Pump driven by the engine,) which compresses and circulates refrigerant gas, a condenser, which behaves similarly to a radiator to release heat and condense gas to a liquid, an evaporator to exhaust the heat from the car and dehumidify refrigerant and an expansion device usually a thermal expansion valve (TXV) or an orifice tube, (subject to the sort of air conditioner system used).
Your car air conditioning is designed to take the excess heat from the air within the passenger area of the car 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
Check air vent temperature is correct
- Confirm condenser temperature ok
- Check suction line temperature ok
- Drive belt and pulley correction
- Check correct operation of thermostats and valves
- Ensure condenser fins are clean
- Ensure adequate condition of of components and hoses
- Evacuation and recharge of refrigerant (where required)
- System line and component check with electronic tester
Why do I need a car air conditioner system service?
Compressor Seizure can be prevented by checking or changing the oil level in the refrigerant. Should the air filters get blocked with dirt and bacteria it will affect the performance of the entire system and it can even cause it to break down completely. As well as impacting air conditioner performance, dirty air filters can cause all kinds of health problems too.
A vehicle air conditioning system ought to be examined annually for any signs of failure of the seals, hoses and connections and confirm refrigerant levels are being maintained over time. Regularly servicing your air conditioning 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 lowers your fuel consumption.
Your car air conditioning is designed to take the excess heat from the air within the passenger area of the car and exhaust 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.
While it functions much like a domestic refrigerator, there are still some significant differences. Due to the fact it is mounted on your car, the air conditioning unit is subject to a vast amount of movement and vibration in addition to operating in an outdoor environment.
Being exposed to the elements and very stressful operating conditions and being expected to operate occasionally rather than being 'Always On' can cause decay of the seals, hoses and connections. An automotive air conditioning system must be checked once a year in addition to being 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. Modern evaporator units tend to be more efficient, but more fins equals increased ability to trap moisture allowing micro-organism development.
Rawson Motors mechanics make use of specialised ultrasonic technology to kill any micro-organisms that may cause bad smells 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.
