Car Air Conditioning Service
Petrie Mechanical Repairs should be your first choice take care of all of your Automotive Air Conditioner repair, inspections or servicing in Petrie and the surrounding areas.
These days cars are often 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. A car air conditioner system uses refrigerant to pull heat from the air within the interior of the car then expell it out of the car, leaving only cooled or 'conditioned' air to be recirculated. It's therefore essential to appraise the condition of the rubber seals for any signs of leaks or fractures which may well be allowing a loss of refrigerant.
Leakage of refrigerant and evaporation mean that your air con system will begin to deteriorate and have to work harder with a resulting increase in fuel consumption. Even new cars can lose as much as 20% of their refrigerant gas within 2 years of purchase.
To allow for this it is strongly recommended that the refrigerant in your Automotive Air Conditioner is replenished completely within four years of the manufacture date and every two to three years after that.
A car air conditioning service once a year means you may assist protection from costly breakdowns now and in the future - and a well serviced Automotive Air Conditioning system actually saves you money because it reduces your overall fuel usage.
You should take your vehicle to a qualified workshop such as Petrie Mechanical Repairs on a regular basis to make sure the air conditioning system continues performing in optimum conditon as well as having the mechanics advise you on 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 renewal in the near future or those that are already damaged beyond repair.
Petrie Mechanical Repairs in Petrie are qualified to manage air conditioning repairs, services and regas on most makes and models (AU36361).
Air Conditioning FAQ's
An automotive air conditioning system can be classified into four basic parts - a compressor (Pump driven by the engine,) which compresses and circulate gas, the condenser to remove heat and condense gas to a liquid, a heat exchanger called an evaporator to withdraw heat from the car and dehumidify refrigerant and an expansion device either an orifice tube or a thermal expansion valve (TXV), (depending on the kind of A/C system used).
Your air conditioner system is designed to extract the heat from the air within the interior of the vehicle then expell it outside, 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 makes up a car air conditioner service?
A typical air conditioner service may include
Air vent temperature check
- Ensure condenser temperature correct
- Suction line temperature test
- Drive belt and pulley correction
- Check operation of thermostats and valves
- Ensure condenser fins are clean
- Check 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?
Seizure of the compressor can be prevented by checking or changing the oil level in the refrigerant. Should the air filters become plugged with dirt and bacteria it will affect the performance of the entire system and it can even cause it to stop operating altogether. On top of degrading air conditioner performance, dirty air filters can cause all kinds of health problems too.
An automotive air conditioning system needs to be checked for problems once a year for any signs of failure of the connections, hoses and seals to make sure there is no loss 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 reduces fuel expenditure.
Your air conditioner system is designed to extract the heat from the air within the interior of the vehicle and expell it outside, 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 in a similar way to a domestic refrigerator, there are a few significant differences. As it is mounted on your car, the air conditioner is subject to a large amount of movement and vibration in addition to operating outdoors.
Being exposed to the mercy of the elements and very intense operating temperatures and being expected to function occasionally rather than being 'Always On' can cause decay of the connections, seals and hoses. Your automotive air conditioner system should be checked once a year while 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 can support the development of bacteria, microbes 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, but more fins equals increased ability to trap moisture allowing micro-organism development.
Petrie Mechanical Repairs mechanics have the capability to use specialist ultrasonic technology to remove any micro-organisms possibly causing any 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.
