GMR Automotive (AU53313) specialises in taking care of your vehicle's air conditioning (AC) regas, repairs, service, and inspection requirements in and around Caboolture.  We acknowledge that modern vehicles are complex, comprising numerous elements that require regular upkeep to ensure they run optimally. Among these components, the car air conditioner is an often-overlooked yet crucial system that impacts the overall fuel efficiency of your vehicle. This article will discuss the importance of routine AC maintenance in optimising your fuel usage, how car ACs work, and how we at GMR Automotive can assist you. Regular Air Con Maintenance and Fuel Efficiency Like your car's engine, the AC system comprises multiple parts that require routine service or replacement for continuous and effective performance. When refrigerant pressure drops due to evaporation over time or leaks, your AC system's functionality starts deteriorating, and it must exert extra effort to perform. This extra work translates into increased fuel consumption. Typically, evaporative or leakage loss of refrigerant means your AC system will begin to wear and work harder, leading to higher fuel usage. It is, therefore, crucial to routinely inspect the condition of rubber seals for leak or fracture signs indicating refrigerant loss. Conducting an annual car AC service can prevent expensive system breakdowns now and later. A properly serviced AC system ensures passengers' safety by protecting them from toxic substances, prevents overheating, and reduces fuel consumption. Here at GMR Automotive, we value environmental conservation, so we offer licensed car AC regas, repairs, service, and inspection by professional technicians. The Functioning of Car Air Conditioners A car air conditioner system is comprised of four critical components, each playing a unique role in cooling the interior of your car. The basic functionality of a car's air conditioner is to extract heat from the air inside your vehicle and displace it outdoors. This process leaves behind 'conditioned' or cooled air for recirculation. The hot interior air is channeled through a gas-filled evaporator, where the refrigerant (in gas form) absorbs the heat, effectively removing it from the car's air. The now heated gas goes through the compressor, where it gets additionally heated via compression. It is then propelled through the condenser, rapidly extracting the refrigerant's heat. Now transformed into a liquid, the refrigerant traverses the expansion device, either a TXV or Orifice tube, regulating its flow towards the evaporator. The high-pressure liquid turns into a low-pressure gas, and a fan blowing over the cold fins of the evaporator completes the process. GMR Automotive: Your Partner in Maintaining Car Air Conditioning Systems At GMR Automotive, we provide reliable and eco-friendly air conditioner maintenance and repair services for your car, ensuring an enjoyable driving experience and optimal fuel efficiency. Trust us to take care of your vehicle while keeping you and the environment safe. Air Conditioning questions answered How do air conditioners work? A car air conditioner system is composed of four essential parts : A belt-driven pump known as a compressor to compress and circulate gas. A radiator like unit called a condenser to redistribute heat and condense gas to a liquid. An expansion device, which could be a thermal expansion valve (TXV) or an orifice tube (subject to the kind of air-con system used). Some systems have an accumulator before the compressor to remove moisture from the refrigerant while TXV systems have a receiver-dryer before the evaporator performs the same crucial task. Both of these parts also store refrigerant. Car air conditioning is designed to pull the heat from the air within the car's interior area and transfer it outside, leaving only cooled or 'conditioned' air to be redistributed. Hot air is passed across a gas-filled evaporator, where the heat is easily absorbed by the refrigerant (in gas form), effectively removing the heat from the air in the car. The now heated gas is pulled through the compressor where it is further heated (via compression). The next stage involves the refrigerant being forced through the condenser to extract the refrigerant's heat quickly. The refrigerant, now condensed to a liquid, then moves through the expansion device (either a TXV or Orifice tube), which regulates the refrigerant's flow to the evaporator, changing the high-pressure liquid to a low-pressure mist (gas). A fan blowing over the evaporator's cold fins produces the cold air being blown into the car, and the entire process then begins all over again. Does the car air conditioner use more fuel? Yes! Your car air conditioning is using fuel. However, it's actually more fuel efficient to run car air conditioning than it is to have your windows down due to aerodynamic drag. If your air conditioning isn't performing its best, it may use more fuel to run. To avoid this, it's important that you have your air conditioning serviced regularly by professionals, like the ones at GMR Automotive.  What's the cause of the bad smell in car air conditioning? The damp environment can promote 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. Although modern evaporator units tend to be more efficient, they have more fins, meaning an increased capability to trap moisture and allow for micro-organism development. How do I know my car air conditioning is due for a service? If you cannot remember when your air conditioning was last serviced, perhaps it's time to book in with the team at GMR Automotive. You should also book in if: Your air conditioning system is blowing warm air There are damp patches or water stains under your dashboard Your car air conditioning system smells funny Your car air conditioning system is making strange noises There is weak air flow from the car air conditioning system Why does the car air conditioner need to be serviced? Car air conditioning is designed to pull the heat from the air within the interior area of the car 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. The compressor needs the right amount of oil in the refrigerant to prevent it from seizing up. Should the air filters be jammed with dirt and bacteria, it will affect the entire system's performance, and it can even cause it to stop working altogether. On top of inhibiting air conditioner efficiency, dirty air filters can cause health problems. Being exposed to the elements and very diverse operating conditions and being used intermittently rather than being 'Always On' can cause decay of the hoses, connections and seals. A vehicle air conditioning system should be examined regularly 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 air filters get dirty and intermittent use can cause seals to dry and crack, allowing them to leak. Even without leaks, the gas in a car air conditioning system will eventually begin to degrade or evaporate over time. It should be recharged as required to keep the air con system in peak running condition. How often should a car air conditioner be serviced? Your automotive air conditioning system needs to be examined once a year for any signs of problems with the seals, hoses and connections and confirm there is no refrigerant reduction over time. Regularly servicing your automotive air conditioner system keeps refrigerant at optimum levels meaning the system does not need to work as hard. This, in turn, protects the system from damage and minimises fuel expenditure. Can I service my own car air conditioner? Only qualified mechanics with the appropriate training, like the ones at GMR Automotive, should attempt to service a car air conditioner. Specific licences are required to service or repair some types of car air conditioning systems, especially where re-gas (recharging of the refrigerant) is concerned. Strict guidelines and procedures must be adhered to when handling certain refrigerants, which must always be fully recovered and not allowed to escape into the atmosphere during servicing. Refrigerant can also pose serious health risks if mishandled. 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, to avoid seriously damaging the system. You can find out more about licensing on the Australian Refrigeration Council (ARC) Website.

Maintaining Car Air Conditioning Systems for Efficient Fuel Usage: A Guide by GMR Automotive

Keep your cool, without global warming. A proactive car air conditioning approach to protecting our environment.  As Australia begins phasing down HFC use (from January 2018), many new vehicle manufacturers may be switching to new air conditioning systems using the more environmentally friendly refrigerant R-1234yf, instead of R-134a. The benefits of using R-1234yf "Twelve Thirty Four", as R-1234yf is sometimes known, is an HFO type refrigerant delivering high performance, resulting in a more efficient air-conditioning system, fewer emissions and reduced fuel consumption. Hydrofluoroolefins (HFO's) have a double carbon bond meaning they trap less heat in the atmosphere than Hydrofluorocarbons (HFC's) and break down faster. Importantly, R-1234yf systems are specifically engineered to prevent refrigerant leakage and loss, including into the interior of the vehicle. The leakage of refrigerants contributes considerably to greenhouse gases. Why the switch? Older type refrigerants accumulate in the upper atmosphere as greenhouse gases and contribute significantly to Global Warming for a considerable time. In the mid-'90s, the old R-12 (or Freon), which takes a long time to break down into a non-greenhouse gas, was replaced with R134a, which breaks down much quicker. R-1234yf takes that improvement to the next level, breaking down in less than half the time of R-134a (and a fraction of the time R-12 can take). R-134a will remain in use for some time and a licensed mechanic can still service R-134a air con systems, but new vehicles will likely use the new systems with R-1234yf. Some already are. Irrespective of what type of refrigerant your car air conditioner uses, a car service workshop undertaking air conditioner service must have the right knowledge and equipment to handle these gases responsibly. You should always take your car to a mechanic with the skills and specialist equipment to undertake air conditioning service safely and correctly.

Modern radiator coolants not only protect your car from overheating, or the fluid from freezing, they also protect the radiator system from corrosion. GMR Automotive in Caboolture are very knowledgeable and experienced in looking after these systems.  It is recommended that you exchange your radiator coolant fluid every two years or 40,000 km's whichever comes first. However the size of the engine, the climate in your area, the age of your current coolant, and the total miles that have been driven can all affect the need to replace the coolant in your radiator. Knowing when to replenish your radiator fluid isn't always easy - obviously, when it has gone a dirty brown colour it's a sign it probably needs to be flushed and replaced - however even fresh-looking coolant could have lost its corrosion protection properties and without measuring its reserve alkalinity there's no signal that it is no longer protecting your vehicle components, and it could even be doing more damage than good. Maintaining good coolant means your radiator system will be much better protected from corrosion and will have a longer life span, it will help prevent you from having to replace expensive engine components. At GMR Automotive in Caboolture at your request, we will perform a full 65 Point Vehicle Inspection report for free as part of any minor, major or log book service. Part of this inspection includes checking the level and condition of coolant in your system and the written report will advise you if we feel a radiator flush, fluid replacement or any repairs are required to maintain the performance of your vehicle.

Even if it looks clean, your coolant still might need replacing!

Faulty and low charge batteries are to be avoided. Don't wait till you're stranded somewhere on the side of the road, hoping for a jump start. It is easy to have your car, bike, truck battery tested or charged up at GMR Automotive in Caboolture.  Often issues occur because we have all reduced how much we drive or decided to only rely on one car (as petrol prices skyrocket!) and have left the other in the garage. But did you know that batteries can still discharge even when your car isn't in use? - ask GMR Automotive about a battery test today!  Our technicians do a battery load test as part of the 65 Point Vehicle Inspection Report that comes free with every car service. If you have concerns, we can do a stand-alone battery test and inspection right here in Caboolture. Car Battery FAQ How do I know if my battery is getting flat or low? The most obvious sign of a flat battery is when your car won't start, but modern motor vehicles can show symptoms like non-essential functions not operating correctly - things like idle stop-start function not working, or the car's air-conditioning not working effectively.
Other signs you might need a new car battery include: Vehicle is slow to start Engine won't start Dash Lights work, but engine won't start Constantly needing a jump start Film or corrosion on the battery Cracked swollen or leaky battery Rotten egg smell under the hood Do I need a new car battery? The most obvious sign of a flat battery is when your car won't start. Modern motor vehicles can show symptoms like the idle stop-start not working or the car's air-conditioning not working to full capacity.

Other signs include cracked, dirty or leaky batteries, a rotten egg smell under the hood of your car, or regularly needing a jump start or recharge. The best way to know if you need a new battery is to get a car battery test at {{{businessName}}} Does a flat battery use more fuel? Yes! When your car battery is running flat, the alternator works harder to recharge the battery. This added load on the engine means it burns more fuel. Where can I buy a new car battery? Come in and see us! As a Repco Authorised Service Centre, {{{businessName}}} have access to the highest quality batteries to suit most vehicles. Who can test my car battery? {{{businessName}}} can do a battery load test. Phone us or visit the workshop today. Why choose {{{businessName}}} for a battery test? If you have concerns about your vehicle's performance, it is wise to get your battery tested at a full-service workshop like {{{businessName}}} rather than at a parts store. That's because we take into consideration the whole vehicle and can diagnose any deeper issues. There is nothing worse than replacing your car battery only to find the problem actually lies elsewhere… except maybe being told your battery test is fine with no explanation for your ongoing issues! Can my car battery be recharged? Yes, in fact the battery is being recharged by the alternator in your car whenever the engine is running. Sometimes this fix isn't enough, and your battery requires an external recharge. It's best to ask the professionals like our team at {{{businessName}}} about this, as you could void the battery warranty by recharging it yourself. Sometimes external recharging is not the best option because every battery eventually reaches a point in its life where replacement is the only answer to avoid unexpected breakdowns. Can I fit my battery myself? The short answer is yes...But! Modern vehicles are “computers on wheels”, so if you decide to DIY you must follow proper installation procedures to avoid damaging the ECM (Engine Control Module) and TCM (Transmission Control Module). Plus, if the battery gets incorrectly installed, items like the radio, the navigation system and security codes may need to be professionally reset. Talk to {{{businessName}}} today. We can recommend the right battery for your needs and install it for you. 

Ever replaced your battery only to find your car problem wasn't fixed? Don't be left feeling flat, get your battery tested at a full service workshop.

Car Battery Testing and FAQ 

Given their crucial role in maintaining contact between your vehicle and the road, tyres play a significant role in ensuring your car's safety and ability to stop effectively. Ensuring your car receives regular servicing is essential to maintaining its optimal condition. As part of this, it's wise to have your tyres checked to monitor their condition and identify any possible issues. In addition, consulting with your trusted mechanic at GMR Automotive can reveal whether your car would benefit from a wheel alignment or wheel balancing, both of which can greatly enhance your driving experience while ensuring maximum safety for you and your passengers. These low-cost solutions are well worth considering to optimise your vehicle's performance. Opting for tyre services from GMR Automotive can be a wise decision due to a number of reasons. At GMR Automotive, we pride ourselves on our reputation for honesty, experience, and local knowledge as independent business owners. With our range of tyres and specialised equipment, we are fully equipped to handle any new tyre fitting, wheel alignment and balancing needs you may have. Additionally, we stand behind all of our work with the Repco Authorised Service Nationwide Warranty. Although checking your tyres is a task that you can undertake yourself, professionals at GMR Automotive are equipped to examine not only the external surface but also the internal condition of your tyres. They possess an in-depth understanding of the appropriate procedures for disassembly, repair and reassembly, as well as any manufacturer or legal requirements involved. When do tyres need replacing? The wear and tear on vehicle tyres can significantly impact your driving experience. Here are three examples of when it's time to replace them: 1. Tread Wear - A tire’s tread is designed to grip the road and channel water away from the tire surface to prevent hydroplaning. Over time, the tread will wear out, becoming less effective and reducing traction. When the tread is down to 1.6mm or less, it’s time to replace the tyres. 2. Punctures or Tears - Tyres can also be damaged by road hazards like potholes, sharp objects, or debris. If you find a puncture or tear in the sidewall or tread of your tyre, it’s essential to get it checked out as soon as possible. In some cases, it may be repairable, but if the damage is too extensive, you’ll need to replace the tyre. 3. Age - Even if your tyres look good and have plenty of tread left, they may still need to be replaced due to age. Tyres have a lifespan of six to ten years, depending on the type and usage. After this time, the rubber will begin to break down, becoming more brittle and prone to failure, even if they’ve been rarely used. Why check tyre pressure? Tyre pressure is not just important to ensure you get the best fuel economy from your vehicle. Incorrect tyre pressure is a common cause of tyre damage as pressure and wear is directed at areas of the tyre not designed to take it. Perhaps most importantly the pressure of your tyres can have a direct impact on the driveability, and therefore the safety, of the vehicle.  We check your tyre pressures and ensure they are correct at every service, but should you have any concerns about your tyres current pressure or what that pressure should be, please give us a call to discuss. Why do tyres need to be rotated? Tyres will suffer from wear and tear at varying rates. The front and rear tyres for example will wear at different rates as front tyres generally carry more weight than rear ones, meaning faster heat build-up and therefore increased wear. The tyres on either side of your car will also tend to wear at different rates to those on the opposite side. Why should tyres be checked regularly? You should check your tyres yourself on a regular basis to ensure they are in good condition. Be on the lookout for bald or flat spots, tears and cuts in the surface of the tyre and any foreign objects likely to cause problems such as stones, nails and other road debris. You should also have a tyre professional give them a check on a regular basis as they have the knowledge and equipment to properly check the entire tyre and may spot issues you simply don't see. Having your tyres rotated regularly, every 8000 to 10,000 km for example, can help to ensure that all of your tyres wear at a similar rate and in the same places. GMR Automotive will be happy to undertake this task for you and inspect each tyre as they do it, letting you know of any issues that might present a problem or you should otherwise be aware of. We can undertake all types of tyre rotation for you including Cross rotation, straight rotation, 5 wheel rotation and four wheel drive rotation. Will a regular wheel alignment or balance help look after tyres? Regular wheel alignment helps to protect against premature or uneven tyre wear, increases the safety and handling of your vehicle and improves ride performance and fuel efficiency. Wheel balancing helps to minimise vibration through the wheels, thereby minimising premature or uneven tyre wear. Either wheel service (or both) will go a long way in helping to maximise the life of your tyres along with safety and handling benefits. It's essential to keep an eye on your vehicle's tyres, checking the tread depth, air pressure, and visual condition regularly. Knowing when it's time to replace them will keep you safe on the road and help avoid any unexpected breakdowns or accidents. GMR Automotive supply and fit a range of tyres suitable for most vehicle types in our Caboolture car service workshop

GMR Automotive advise that regular tyre inspection ensures safety, improves performance, and prolongs your tyre's life.
