Car Air Conditioning Service
Power Drive Automotive Repairs are your best choice to carry out all of your Car Air Conditioner repairs, servicing or inspections in Knoxfield and the surrounding areas.
Modern cars are extremely complex and just like the engine, a vehicles 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. Automotive air conditioning uses refrigerant to absorb heat from the air within the inside of the vehicle and send it out of the vehicle, leaving only cooled or 'conditioned' air to be recirculated. It should be considered important to scrutinise the condition of the rubber seals for any signs of leaks or issues which may be a sign of refrigerant loss.
Evaporation occurring over time or leaks may diminish refrigerant pressure meaning your air con system will begin to deteriorate and have to work harder increasing your fuel consumption. Even new cars can lose as much as 20% of their refrigerant gas within 2 years of purchase.
To avoid this happening it is strongly recommended that the refrigerant in your Car Air Conditioning system is replenished 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 assist in protecting the air-con against costly breakdowns now and in the future - and a well serviced Car Air Conditioning system actually saves you money because it results in a reduction of fuel expenditure.
Your vehicle should be inspected by a qualified workshop such as Power Drive Automotive Repairs (AU17234) on a regular basis to make sure the air conditioning system continues performing correctly as well as having the mechanics check out the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 point vehicle inspection report with every service and can provide a warning about any items that may need renewing in the near future or those that are already damaged beyond repair.
Power Drive Automotive Repairs in Knoxfield are qualified to perform air conditioning repairs, services and regas on most makes and models (AU17234).
Air Conditioning FAQ's
An automotive air conditioning system can be broken down to four basic parts - a pump driven by a belt, known as a compressor (to compress and ciculate gas), a radiator like unit called a condenser to remove heat and condense gas to a liquid, an evaporator to extract heat from the car and remove moisture from refrigerant and an expansion device either an orifice tube or a thermal expansion valve (TXV), (subject to the sort of air-con system used).
Your car air conditioning system is designed to remove the excess heat from the air in the interior area of the vehicle and send 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 comprises a car air conditioner service?
A typical air conditioner service may include
Air vent temperature assessment
- ensure condenser temperature correct
- Suction line temperature evaluation
- Drive belt and pulley adjusted
- Validate correct operation of valves and thermostats
- Ensure cleanliness of the fins of the condesner
- Assess 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 passing through the compressor can help avoid it seizing up. Air filters clogged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit operating altogether. In addition to impacting air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
An automotive air conditioner system needs to be checked for problems yearly for any signs of problems with the hoses, connections and seals and confirm there is no reduction of refrigerant over time. Regularly servicing your automotive air con 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 lowers your fuel consumption.
Your car air conditioning system is designed to remove the excess heat from the air in the interior area of the vehicle and send 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 operates in a similar way to a domestic refrigerator, there are a few significant differences. Seeing as it is mounted on your car, the air conditioner is subjected to a vast amount of movement and vibration as well as performing outdoors.
Being exposed to the mercy of the elements and very stressful operating temperatures and being expected to run occasionally rather than being 'Always On' can cause failure of the hoses, connections and seals. An automotive air conditioner system ought to be checked once a year in addition to being fully 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 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. Modern evaporator units tend to be more efficient, but more fins equals increased capability to trap moisture and allow for micro-organism development.
Power Drive Automotive Repairs mechanics make use of special ultrasonic technology to ensure elimination of any micro-organisms that may be the source of 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.
