Car Air Conditioning Service
Macgregor Auto Service are qualified to deal with all of your Vehicle Air Conditioning inspections, repair and servicing in Macgregor and the surrounding areas.
Todays vehicles can be very complex and just like the engine, you need to get a regular service on your air conditioning system.
Don’t Melt In Your Car
Send the heat packing. Your car air conditioner system uses refrigerant to remove excess heat from the air in the interior area of the vehicle then send it outside, leaving only cooled or 'conditioned' air behind to be recirculated. It should be considered critical to inspect the condition of the rubber seals for any signs of leaks or decline which could point to a loss of refrigerant.
If this refrigerant starts to leak or evaporate 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 in the first two years.
To address this problem it is strongly recommended that the refrigerant in your Vehicle Air Conditioner system is refilled completely within four years of the manufacture date and every two to three years after that.
By getting a yearly Car air conditioning service you can assist prevention of costly breakdowns now and in the future - and a well serviced Car Air Conditioner actually saves you money because it reduces your overall fuel usage.
Your car should be taken to a qualified workshop such as Macgregor Auto Service regularly to make sure the air conditioning system continues performing efficiently as well as having the mechanics review the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and can give you a warning about any items that may need replacing in the near future or those that are already worn beyond repair.
Macgregor Auto Service in Macgregor are qualified to undertake air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
An automotive air conditioner system contains four basic parts - the compressor, a belt driven pump to compress and circulate gas, a radiator like unit called a condenser (removes heat and condenses gas to a liquid), the evaporator (a type of heat exchanger) to remove heat from the car and dehumidify refrigerant and an expansion device either a thermal expansion valve (TXV) or an orifice tube, (dependent on the kind of A/C system used).
Your car air conditioner system is designed to pull the heat from the air within the interior area of the vehicle then send it outside, 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 comprises a car air conditioner service?
A typical air conditioner service may include
Air vent temperature inspection
- Test condenser temperature
- Evaluate suction line temperature
- Confirm operation of drive belt & pulley ok
- Validate correct operation of thermostats and valves
- Confirm condenser fins are free of dirt or debris
- Inspect condition of of hoses and components
- 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?
Checking or changing the oil level in the refrigerant you protect the compressor and stop it from seizing up. Should the air filters become clogged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to stop functioning altogether. Along with degrading air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
A vehicle air conditioner system must be inspected annually for any signs of issues with the connections, hoses and seals to make sure there is no reduction of refrigerant over time. Regularly servicing 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 reduces the amount of fuel you burn.
Your car air conditioner system is designed to pull the heat from the air within the interior area of the vehicle then expell it outside, 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 operates much like a domestic refrigerator, there are a couple of crucial differences. Seeing how it is mounted on your car, the air conditioning unit is subjected to an epic amount of movement and vibration as well as operating in an outdoor environment.
Being exposed to the elements and very extreme operating temperatures and being switched on occasionally rather than being 'Always On' can cause failure of the connections, seals and hoses. Your car air conditioner should be inspected annually while 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 moist environment inside the evaporator core can promote the development of bacteria, microbes and even fungus growth. 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.
Macgregor Auto Service 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.
