Car Air Conditioning Service
Combined Automotive Services are the best mechanics to handle all of your Car Air Conditioner repair, service or inspections in Milton and the surrounding areas.
Todays vehicles are very complex and just like the engine, your vehicles air conditioner system has elements that need to be serviced or replaced on a regular basis.
Don’t Melt In Your Car
Send the heat packing. Your air conditioner system uses refrigerant to remove the heat from the air in the interior area of the car and transfer it out of the vehicle, leaving only cooled or 'conditioned' air to be recirculated. It's therefore essential to perform an evaluation of the condition of the rubber seals for any signs of leaks or decay which may be a sign of refrigerant loss.
When this refrigerant has started to leak or evaporate your air con system will begin to deteriorate and have to work harder raising your overall fuel usage. Even new cars can lose around twenty percent of their refrigerant gas in the first two years.
To perform in optimum condition it is strongly recommended that the refrigerant in your Automotive Air Conditioner is replenished completely within four years of the manufacture date and every two to three years after that.
Getting your car's air conditioning serviced every twelve months means you assist in preventing costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioner actually saves you money because it reduces the amount of fuel you use.
You should take your car to a qualified workshop such as Combined Automotive Services on a regular basis to ensure the air conditioner system continues performing at its best as well as having the mechanics evaluate the condition of the entire car.
Repco Authorised Car Service mechanics perform a 65 point safety check with every service and are often able to provide a warning about any items that may need renewal in the near future or those that are already worn beyond repair.
Combined Automotive Services in Milton are qualified to conduct air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
A car air conditioning system can be classified into four basic parts - the compressor, a belt driven pump to compress and circulate refrigerant gas, a radiator like unit known as a condenser to release heat and condense gas to a liquid, a heat exchanger called an evaporator to remove heat from the car and dehumidify refrigerant and an expansion device which could be a thermal expansion valve (TXV) or an orifice tube, (dependent on the type of air-con system used).
A vehicle air conditioner system is designed to absorb heat from the air in the interior of the car and transfer it out of the car, 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 takes place in a a car air conditioner service?
A typical air conditioner service may include
Air vent temperature inspection
- Check condenser temperature correct
- Ensure suction line temperature correct
- Corrections of drive belt and pulley
- Check that valves and thermostats are operating correctly
- Clean the condenser fins
- Ensure good condition of of hoses and components
- Evacuation and recharge of refrigerant (where required)
- Electronically inspect system lines and components for leaks
Why do I need a car air conditioner system service?
Checking or changing the oil level in the refrigerant you protect the compressor and stop it from seizing up. If the air filters are obstructed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit working completely. Along with reducing air conditioner performance, dirty air filters can cause all kinds of health problems too.
A car air conditioning system needs to be checked for problems annually for any signs of decay of the seals, hoses and connections to make sure refrigerant is not being lost over time. Regularly servicing your car 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 results in a reduction of fuel consumed.
A vehicle air conditioner system is designed to absorb heat from the air in the interior of the car and carry it out of the car, 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.
Even though it carries out its task in a way similar to a domestic refrigerator, there are still a number of significant differences. Because it is mounted on your car, the air conditioning unit is subject to an enormous amount of movement and vibration in addition to having to perform in an outdoor environment.
Being exposed to the elements and very stressful operating conditions and being used occasionally rather than being 'Always On' can cause issues with the connections, hoses and seals. Your air conditioning System needs to be inspected annually as well as 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 be the perfect breeding ground for microbes, bacteria and even fungus due to the moist conditions found there. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. Newer type evaporator units tend to be more efficient, yet have increased capability to trap moisture and allow for micro-organism development.
Combined Automotive Services mechanics can use specialised ultrasonic technology to ensure the destruction of any micro-organisms that may cause unpleasant smells 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.
