Car Air Conditioning Service
Prompt Auto Repairs are certified to perform all of your Vehicle Air Conditioner repair, service and inspections in Coconut Grove and the surrounding areas.
Todays vehicles are sometimes 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. Automotive air conditioners use refrigerant to extract excess heat from the air in the passenger area of the car then carry it outside, leaving only cooled or 'conditioned' air to be redistributed. It should be considered important that the rubber seals are evaluated for any signs of leaks or decline which may contribute to an ongoing loss of refrigerant.
Evaporation occurring over time or leaks may diminish refrigerant pressure meaning your air con system will begin to deteriorate and have to work harder raising your fuel consumption. Even new cars can lose around 20% of their refrigerant gas within two years of purchase.
To allow for this it is strongly recommended that the refrigerant in your Vehicle 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 twelve months means you assist in protecting the air-con against 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 Prompt Auto Repairs on a regular basis to ensure the air conditioner system continues performing in optimum conditon as well as having the mechanics check the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and provide a heads up about any items that may need to be renewed in the near future or those that are already damaged beyond repair.
Prompt Auto Repairs in Coconut Grove are qualified to carry out air conditioning repairs, services and regas on most makes and models (AU33713).
Air Conditioning FAQ's
A car air conditioning system can be broken down to four basic parts - the compressor, a belt driven pump to compress and circulate gas, a condenser, which behaves similarly to a radiator to remove heat and condense gas to a liquid, a heat exchanger called an evaporator to extract heat from the car and remove moisture from refrigerant and an expansion device called an orifice tube or a thermal expansion valve (TXV), (dependent on the type of air conditioner system used).
Your car air conditioner system is designed to remove the heat from the air in the interior area of the car then carry 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 happens during a car air conditioning service?
A typical air conditioner service may include
Air vent temperature check
- Ensure condenser temperature correct
- Suction line temperature check
- Drive belt and pulley adjustment
- Check operation of valves and thermostats
- Check condenser fins are clean
- Assess condition of of components and hoses
- Evacuation and recharge of refrigerant (where required)
- System line and component evaluation with electronic tester
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. Should the air filters become obstructed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to fail to work altogether. Along with degrading air conditioner performance, dirty air filters can cause all kinds of health problems too.
An automotive air conditioner system must be checked for problems annually for any signs of decay in the connections, seals and hoses and confirm refrigerant levels have not diminished over time. Regular service of your vehicle 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 results in a reduction of fuel being used up.
Your car air conditioner system is designed to remove the heat from the air in the interior area of the car then send 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.
While it carries out its task in a way similar to a domestic refrigerator, there are still some significant differences. Being mounted on your car, the air conditioning unit is subject to a sizable amount of movement and vibration as well as performing outdoors.
Being exposed to the mercy of the elements and very intense operating conditions and being expected to operate intermittently rather than being 'Always On' can have a detrimental effect on the seals, hoses and connections An automotive air conditioner needs to be examined yearly and 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 moist environment can support the development of bacteria, microbes and even fungus growth inside the evaporator core. 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.
Prompt Auto Repairs mechanics employ specialised ultrasonic technology to get rid of any micro-organisms possibly causing any unpleasant 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.
