Car Air Conditioning Service
Geoff Nichols Engines Mechanical & 4x4 are the logical choice to carry out all of your Car Air Conditioner servicing, repair and inspections in Singleton and the surrounding areas.
Todays vehicles are often very complex and just like the engine, a car air conditioner 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 uses refrigerant to absorb the heat from the air within the interior of the car then relocate it out of the vehicle, leaving only cooled or 'conditioned' air to be redistributed. It should be considered crucial to evaluate the condition of the rubber seals for any signs of leaks or damage which could point to a loss of refrigerant.
Leaks and evaporation may reduce the refrigerant levels over time meaning your air con system will begin to deteriorate and have to work harder with a resulting increase in fuel being burned. Even new cars can lose as much as 20% of their refrigerant gas in the first two years.
To allow for this it is strongly recommended that the refrigerant in your Automotive Air Conditioning system 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 can help protect against costly breakdowns now and in the future - and a well serviced Car Air Conditioner actually saves you money because it reduces the amount of fuel you burn.
Your car should be inspected by a qualified workshop such as Geoff Nichols Engines Mechanical & 4x4 on a regular basis to make sure the air conditioning system continues performing efficiently as well as having the mechanics review the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection report with every service and are able to give you a warning about any components that may need replacing in the near future or those that are already damaged beyond repair.
Geoff Nichols Engines Mechanical & 4x4 in Singleton are qualified to perform 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 - the compressor, a belt driven pump to compress and circulate refrigerant gas, a radiator like unit known as a condenser to release heat and condense gas to a liquid, an evaporator to exhaust the heat from the car and remove moisture from refrigerant and an expansion device called an orifice tube or a thermal expansion valve (TXV), (depending on the kind of air conditioner system used).
An automotive air conditioner system is designed to take the heat from the air within the interior of the car then relocate it to the exterior, 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 takes place in a a car air conditioning service?
A typical air conditioner service may include
Ensure air vent temperature correct
- Check condenser temperature
- Suction line temperature assessment
- Adjustments of pulley and drive belt
- Ensure that valves and thermostats are operating correctly
- Clean the fins of the condenser
- Assess 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?
By checking or changing the oil level in the refrigerant you protect the compressor and prevent it seizing up. When the air filters are plugged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit working completely. On top of inhibiting air conditioner performance, dirty air filters can cause all kinds of health problems too.
Your vehicle air conditioner must be examined yearly for any signs of issues with the connections, hoses and seals and confirm refrigerant is not leaking 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 results in a reduction of fuel being burned.
An automotive air conditioner system is designed to take the heat from the air within the interior of the car and send it to the exterior, 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.
Although it operates similarly to a domestic refrigerator, there are still several significant differences. Due to the fact it is mounted on your car, the air conditioner is subjected to an extensive amount of movement and vibration in addition to having to function outdoors.
Being exposed to the mercy of the elements and very intense operating conditions and being run occasionally rather than being 'Always On' can cause issues with the connections, hoses and seals. An automotive air conditioner system needs to be checked annually while being properly 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 core of the evaporator can be the perfect breeding ground for microbes, bacteria and even fungus due to the moist conditions found there. 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.
Geoff Nichols Engines Mechanical & 4x4 mechanics will use specialised ultrasonic technology to deal with any micro-organisms that may be the source of bad 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.
