Car Air Conditioning Service
Palmerston Mechanical Centre are licensed to undertake all of your Vehicle Air Conditioner repairs, servicing and inspections in Palmerston and the surrounding areas.
Todays vehicles are often very complex and just like the engine, a typical car 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. A car air conditioner system uses refrigerant to extract the excess heat from the air in the car and exhaust it to the exterior, leaving only cooled or 'conditioned' air to be recirculated. It should be considered crucial to carry out an appraisal of the condition of the rubber seals for any signs of leaks or failure which could be an indication of a loss of refrigerant.
Reduced levels of refrigerant from leaks or evaporation mean your air con system will begin to deteriorate and have to work harder meaning you are using even more fuel. Even new cars can lose as much as 20% of their refrigerant gas within 2 years of purchase.
To avoid this problem it is strongly recommended that the refrigerant in your Automotive Air Conditioner is recharged completely within four years of the manufacture date and every two to three years after that.
Having your car's air conditioning serviced annually means you generally assist protection from costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioner system actually saves you money because it reduces the amount of fuel being burned.
You ought to take your vehicle to a qualified workshop such as Palmerston Mechanical Centre on a regular basis to make sure the air conditioning system continues performing in top conditon 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 alert you to any components that may need to be replaced in the near future or those that are already damaged beyond repair.
Palmerston Mechanical Centre in Palmerston are qualified to perform air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
An automotive air conditioner system is composed of four basic parts - a belt driven pump known as a compressor to compress and circulate gas, the condenser to dissipate heat and condense gas to a liquid, a heat exchanger called an evaporator to extract heat from the car and dehumidify refrigerant and an expansion device either an orifice tube or a thermal expansion valve (TXV), (depending on the kind of A/C system used).
A car air conditioner system is designed to remove the excess heat from the air inside the vehicle and exhaust it to the exterior, leaving only cooled or 'conditioned' air behind 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 is done during a car air conditioner service?
A typical air conditioner service may include
Check air vent temperature
- Condenser temperature test
- Check suction line temperature ok
- Validate correct drive belt & pulley operation
- Confirm that valves and thermostats are operating correctly
- Clean the condenser fins
- Evaluate condition of of components and hoses
- Evacuation and recharge of refrigerant (where required)
- inspect system lines and components for leaks
Why do I need a car air conditioner system service?
By checking or changing the oil level in the refrigerant you protect the compressor and prevent it seizing up. When the air filters are jammed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit completely. Aside from reducing air conditioner performance, dirty air filters can cause all kinds of health problems too.
An automotive air conditioner should be examined annually for any signs of failure of the connections, hoses and seals to ensure refrigerant is not being lost 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 results in a reduction of fuel being burned.
A car air conditioner system is designed to remove the excess heat from the air inside the vehicle then relocate it to the exterior, leaving only cooled or 'conditioned' air behind 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 similarly to a domestic refrigerator, there are several significant differences. Seeing how it is mounted on your car, the air conditioner is subject to a gigantic amount of movement and vibration in addition to having to perform outdoors.
Being exposed to the elements and very difficult operating conditions and being run intermittently rather than being 'Always On' can cause failure of the connections, hoses and seals. An automotive air conditioning system must be checked annually and properly serviced every 24 months 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 support 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. Newer type evaporator units may be more efficient but they are often more likely to trap moisture allowing microorganism growth.
Palmerston Mechanical Centre mechanics make use of specialist ultrasonic technology to exterminate any micro-organisms that may cause bad odours 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.
