Car Air Conditioning Service
On The Move Mechanical Repairs are certified to undertake all of your Automotive Air Conditioner repairs, inspections and servicing in Preston and the surrounding areas.
Modern vehicles are very complex and just like the engine, your vehicles air conditioner 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 take the heat from the air within the inside of the vehicle then expell it to the exterior, leaving only cooled or 'conditioned' air to be recirculated. It is therefore essential to study the condition of the rubber seals for any signs of leaks or damage which may indicate a loss of refrigerant.
As refrigerant levels decrease from evaporation or leaks your air con system will begin to deteriorate and have to work harder increasing the amount of fuel you burn. Even new cars can lose as much as twenty percent of their refrigerant gas within two years of purchase.
For best performance 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.
Having your car's air conditioning serviced every twelve months means you help prevent costly breakdowns now and in the future - and a well serviced Car Air Conditioner actually saves you money because it reduces fuel expenditure.
You should take your car to a qualified workshop such as On The Move Mechanical Repairs regularly to make sure the air conditioning system continues performing as it should as well as having the mechanics appraise 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 renewed in the near future or those that are already worn beyond repair.
On The Move Mechanical Repairs in Preston are qualified to undertake air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
An automotive air conditioning system is made up of of four basic parts - a pump driven by a belt, known as a compressor (to compress and ciculate gas), the condenser to release heat and condense gas to a liquid, an evaporator to exhaust the heat from the car and dehumidify refrigerant and an expansion device which could be a thermal expansion valve (TXV) or an orifice tube, (dependent on the kind of air-con system used).
An automotive air conditioning system is designed to remove excess heat from the air in the vehicle then expell it to the outside, 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 makes up a car air conditioner service?
A typical air conditioner service may include
Ensure air vent temperature correct
- Condenser temperature test
- Confirm suction line temperature correct
- Pulley and drive belt adjusted
- Ensure that valves and thermostats are operating correctly
- Ensure condenser fins are free of dirt or debris
- Inspection of hoses and components
- Evacuation and recharge of refrigerant (where required)
- Use electronic leak detector to ensure no system lines and components leak
Why do I need a car air conditioner system service?
The oil level in the refrigerant passing through the compressor must be checked or changed to avoid it seizing up. Air filters jammed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to stop working altogether. Aside from impacting air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
An air conditioning system must be checked for problems yearly for any signs of issues with the connections, seals and hoses to ensure refrigerant pressure is being maintained over time. Regularly servicing your auto 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 means less fuel is being expended.
An automotive air conditioning system is designed to remove excess heat from the air in the vehicle then exhaust it to the outside, 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 functions in a way like a domestic refrigerator, there are also crucial differences. Seeing how it is mounted on your car, the air conditioning system is subject to a huge amount of movement and vibration as well as operating outdoors.
Being exposed to the elements and very diverse operating temperatures and being run intermittently rather than being 'Always On' can cause failure of the connections, seals and hoses. A vehicle air conditioner must be examined annually and 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 can support the development of microbes, bacteria 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. Modern evaporator units tend to be more efficient, yet have increased capability to trap moisture and allow for micro-organism development.
On The Move Mechanical Repairs mechanics make use of special ultrasonic technology to deal with any micro-organisms that may be the source of 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.
