Car Air Conditioning Service
Metcalfe Automotive Centre are qualified to perform all of your Car Air Conditioning repairs, service or inspections in Northmead and the surrounding areas.
Modern vehicles are extremely complex and just like the engine, your automotive air conditioning system has components 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 remove heat from the air within the interior area of the vehicle and relocate it out of the car, leaving only cooled or 'conditioned' air behind to be redistributed. It's therefore very important to perform an evaluation of the condition of the rubber seals for any signs of leaks or detoriation which may be a signal of refrigerant loss.
If refrigerant starts to evaporate or leak your air con system will begin to deteriorate and have to work harder increasing your fuel consumption. Even new cars can lose around 20% of their refrigerant gas within two years of purchase.
To address this problem it is strongly recommended that the refrigerant in your Car 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 yearly means you help prevent costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioner actually saves you money because it uses less fuel.
You ought to bring your vehicle to a qualified workshop such as Metcalfe Automotive Centre regularly to ensure the air conditioner system continues performing as it should as well as having the mechanics appraise 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 give you a warning about any items that may need renewing in the near future or those that are already worn beyond repair.
Metcalfe Automotive Centre in Northmead are qualified to take care of air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
A car air conditioning system could be seen as having four basic parts - a belt driven pump called a compressor to compress and circulate refrigerant gas, a radiator like unit called a condenser (dissipates heat and condense gas to a liquid), a heat exchanger called an evaporator to remove heat from the car and remove moisture from refrigerant and an expansion device usually an orifice tube or a thermal expansion valve (TXV), (depending on the sort of A/C system used).
A vehicle air conditioning system is designed to remove excess heat from the air in the interior of the vehicle and relocate it out of the vehicle, 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 involved in a car air conditioner service?
A typical air conditioner service may include
Air vent temperature evaluation
- Condenser temperature assessment
- Ensure suction line temperature ok
- Drive belt and pulley adjustment
- Operational check of valves and thermostats
- Ensure cleanliness of the fins of the condesner
- Check condition of of hoses and components
- Evacuation and recharge of refrigerant (where required)
- inspect system lines and components for leaks
Why do I need a car air conditioner system service?
Seizing of the compressor can be avoided by checking or changing the oil level in the refrigerant. Air filters overwhelmed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to break down altogether. Aside from impacting air conditioner performance, dirty air filters can cause all kinds of health problems too.
A car air conditioning system must be examined annually for any signs of issues with the seals, hoses and connections and ensure refrigerant levels have not diminished over time. Regularly servicing your car 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 expenditure.
A vehicle air conditioning system is designed to remove excess heat from the air in the interior of the vehicle then send it out of the vehicle, 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.
Although it operates much like a domestic refrigerator, there are various crucial differences. Being mounted on your car, the air conditioning system is subjected to a prodigious amount of movement and vibration as well as operating in an outdoor environment.
Being exposed to the elements and very stressful operating conditions and being switched on occasionally rather than being 'Always On' can cause issues with the hoses, connections and seals. A vehicle air conditioner system must be checked yearly as well as being 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 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. While modern evaporator units tend to be more efficient, they have an increased capability to trap moisture and allow for micro-organism development.
Metcalfe Automotive Centre mechanics make use of specialist ultrasonic technology to eradicate any micro-organisms that may be causing 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.
