Car Air Conditioning Service
Matlin Auto Repairs are able to take care of all of your Vehicle Air Conditioning inspections, repairs and servicing in Richmond and the surrounding areas.
These days cars are often complex and just like the engine, your car's air conditioning system needs a regular service.
Don’t Melt In Your Car
Send the heat packing. Car air conditioner systems use refrigerant to withdraw the heat from the air in the interior of the vehicle and relocate it to the exterior, leaving only cooled or 'conditioned' air to be redistributed. It is crucial to make a careful examination of the condition of the rubber seals for any signs of leaks or wear which may be a signal of refrigerant loss.
Refrigerant can leak or evaporate over time meaning your air con system will begin to deteriorate and have to work harder raising your overall fuel usage. Even new cars can lose around 20% of their refrigerant gas in the first two years.
To allow for this issue it is strongly recommended that the refrigerant in your Car Air Conditioner system is refilled 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 often assist prevention of costly breakdowns now and in the future - and a well serviced Vehicle Air Conditioner system actually saves you money because it results in a reduction of fuel being burned.
You ought to drop off your car to a qualified workshop such as Matlin Auto Repairs on a regular basis to make sure the air conditioning system continues performing as it should as well as having the mechanics check out the condition of the entire car.
Repco Authorised Car Service mechanics perform a 65 point safety check with every service and can give you a warning about any items that may need renewing in the near future or those that are already damaged beyond repair.
Matlin Auto Repairs in Richmond are qualified to conduct air conditioning repairs, services and regas on most makes and models.
Air Conditioning FAQ's
A car air conditioning system can be classified into four basic parts - a pump driven by a belt, known as a compressor (to compress and ciculate gas), a radiator like unit known as a condenser (to dissipate heat and condense gas to a liquid), a heat exchanger called an evaporator to take the heat from the car and remove moisture from refrigerant and an expansion device called a thermal expansion valve (TXV) or an orifice tube, (subject to the type of a/c system used).
A car air conditioner is designed to absorb the heat from the air inside the vehicle and relocate it to the exterior, leaving only cooled or 'conditioned' air behind 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 is involved in a car air conditioner service?
A typical air conditioner service may include
Assess air vent temperature
- Check condenser temperature ok
- Evaluate suction line temperature
- Adjustments of pulley and drive belt
- Ensure correct operation of valves and thermostats
- Validate condenser fins are clean
- Confirm good condition of of hoses and components
- Evacuation and recharge of refrigerant (where required)
- Electronically check system lines and components for leaks
Why do I need a car air conditioner system service?
To prevent the compressor seizing the oil level in the refrigerant must be checked or changed. Should the air filters get obstructed with dirt and bacteria it will affect the performance of the entire system and it can even cause it to stop functioning completely. Along with impacting air conditioner efficiency, dirty air filters can cause all kinds of health problems too.
A car air conditioner system must be examined yearly for any signs of problems with the seals, hoses and connections to ensure refrigerant is not leaking over time. Regularly servicing your car 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.
A car air conditioner is designed to absorb the heat from the air inside the vehicle then send it to the exterior, leaving only cooled or 'conditioned' air behind 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.
While it functions similarly to a domestic refrigerator, there are also significant differences. Due to the fact it is mounted on your car, the air conditioning system is subject to a large amount of movement and vibration in addition to having to perform in an outdoor environment.
Being exposed to the elements and very harsh operating conditions and being operated intermittently rather than being 'Always On' can cause problems on the connections, seals and hoses. Your automotive air conditioner system should be checked yearly in addition to being 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 evaporator core can be the perfect breeding ground for microbes, bacteria and even fungus due to the damp conditions found there. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. Modern evaporator units may be more efficient but they are often more likely to trap moisture allowing microorganism growth.
Matlin Auto Repairs mechanics have access to special ultrasonic technology to eliminate 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.
