Car Air Conditioning Service
Mills-Thom`s Mechanical Repairs are the best mechanics to undertake all of your Automotive Air Conditioning inspections, repairs or servicing in Coffs Harbour and the surrounding areas.
Modern cars are very complex and just like the engine, your automotive 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. Automotive air conditioning uses refrigerant to extract heat from the air within the inside of the car and transfer it to the outside, leaving only cooled or 'conditioned' air to be redistributed. It should be considered essential to study the condition of the rubber seals for any signs of leaks or wearing which could well be allowing a loss of refrigerant.
If this refrigerant starts to leak or evaporate your air con system will begin to deteriorate and have to work harder with a resulting increase in fuel expenditure. Even new cars can lose around twenty percent of their refrigerant gas within 2 years of purchase.
To compensate for this issue it is strongly recommended that the refrigerant in your Car Air Conditioner is refilled completely within four years of the manufacture date and every two to three years after that.
A car air conditioning service every twelve months means you may assist protection from costly breakdowns now and in the future - and a well serviced Automotive Air Conditioner actually saves you money because it burns less fuel.
You should send your vehicle to a qualified workshop such as Mills-Thom`s Mechanical Repairs regularly to make sure the air conditioning system continues performing as it should as well as having the mechanics examine the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and are often able to give you a warning about any items that may need to be replaced in the near future or those that are already worn beyond repair.
Mills-Thom`s Mechanical Repairs in Coffs Harbour are qualified to take charge of 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 - the compressor, a pump driven by a belt to compress and circulate refrigerant gas, a radiator like unit called a condenser (redistributes heat and condenses gas to a liquid), an evaporator to take the heat from the car and dehumidify refrigerant and an expansion device called an orifice tube or a thermal expansion valve (TXV), (depending on the sort of A/C system used).
An automotive air conditioner is designed to extract the excess heat from the air in the vehicle and transfer it out of the car, 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 included in a car air conditioning service?
A typical air conditioner service may include
Make sure air vent temperature is correct
- Check condenser temperature is correct
- Ensure suction line temperature ok
- Adjust pulley and drive belt
- Validate correct operation of thermostats and valves
- Ensure condenser fins are free of dirt or debris
- Check condition of of components and hoses
- 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?
Checking or changing the oil level in the refrigerant passing through the compressor can help 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 fail completely. On top of impacting air conditioner performance, dirty air filters can cause all kinds of health problems too.
A car air conditioner system ought to be examined yearly for any signs of breakdown of the hoses, connections and seals to ensure there is no reduction of refrigerant over time. Regularly servicing your vehicle 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 minimises fuel expenditure.
An automotive air conditioner is designed to extract the excess heat from the air in the vehicle and move it out of the car, 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 still a few crucial differences. As it is mounted on your car, the air conditioning system is subject to a sizable amount of movement and vibration as well as functioning outdoors.
Being exposed to the elements and very harsh operating conditions and being in use intermittently rather than being 'Always On' can cause problems on the connections, seals and hoses. A car air conditioner system ought to be examined annually and 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 become a breeding ground for microbes, bacteria and even fungus due to the moist environment. 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 ability to trap moisture allowing micro-organism development.
Mills-Thom`s Mechanical Repairs mechanics can use specialist ultrasonic technology to exterminate any micro-organisms possibly causing any unpleasant odours 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.
