We’ll Find the Problem Fast There’s never a convenient time for your car not to start. Whether you’re stuck at home, at work, or out and about in Bunbury, a non-starting vehicle can quickly disrupt your entire day. At Autotech Bunbury, we specialise in fast, accurate breakdown diagnostics to identify why your car won’t start—and get you back on the road as quickly as possible. As an RAC Authorised Roadside Assistance Contractor, we’ve seen every type of starting issue and know exactly what to look for. Common Reasons Your Car Won’t Start A vehicle that won’t start can be caused by a range of issues—some simple, others more complex. Our team uses professional diagnostic tools and real-world RAC experience to pinpoint the fault quickly. The most common causes include: Flat or failing battery 
The number one cause of breakdowns. Batteries can fail without warning, especially if nearing the end of their lifespan. Starter motor failure 
If you hear a clicking sound but the engine won’t turn over, the starter motor may be the issue. Alternator or charging system problems 
A faulty alternator won’t keep the battery charged, leading to repeated starting issues. Fuel system faults 
Problems with fuel delivery can prevent your engine from firing up. Ignition or electrical faults 
Modern vehicles rely heavily on electronics—faults here can stop your car starting entirely. Engine immobiliser or key issues 
Sometimes the issue isn’t mechanical at all, but related to your vehicle’s security system. RAC Breakdown Experience You Can Trust As a trusted RAC contractor, Autotech Bunbury is often the team called when vehicles won’t start at the roadside. That hands-on experience gives us a major advantage—we don’t just guess, we diagnose based on real breakdown scenarios we see every day.

Our Breakdown Diagnostic Process When you bring your vehicle to Autotech Bunbury, we: Perform a full battery and electrical system test Check the starter motor and alternator performance Scan the vehicle using advanced diagnostic equipment Inspect related systems (fuel, ignition, immobiliser) Clearly explain the issue and recommended repair We focus on accuracy first, so you’re not paying for unnecessary parts or guesswork.

Autotech Bunbury (AU36994) are the right choice to undertake all your Car Air Conditioning Regas, Servicing, Repair or Inspection needs in Bunbury and the surrounding areas. Keeping your vehicle’s climate system working efficiently isn’t just about comfort - it can sometimes influence how much fuel your car consumes over time. In this article, we break down the mechanics behind AC fuel use, common symptoms of under-performing systems, and practical maintenance tips to help you stay cool without wasting fuel. How Air Conditioning Uses Fuel Car air conditioning systems use engine power to drive the compressor and circulate refrigerant. When systems are operating inefficiently — for example, due to low refrigerant levels or worn components — they place extra load on the engine, which can increase fuel use. This doesn’t necessarily mean huge spikes in consumption, but over time and in hot conditions, inefficiencies can add up. What Causes Reduced AC Efficiency Common reasons your air conditioning may be working harder than needed include: Low refrigerant from leaks Worn seals or hoses Clogged cabin filters Aging compressor components When these problems go unchecked, the system may run longer or harder to reach the same cooling effect, which in turn uses more fuel than necessary. Signs Your AC Isn’t Running Efficiently These signs can alert you that your climate system isn’t operating optimally. Watch for these indicators: Warm or inconsistent airflow Noticeable drop in cooling power Odd smells from vents Higher than expected fuel consumption Routine Care Helps Efficiency Regular inspection of your air conditioning system — including checking refrigerant levels, seals, and filters — can help maintain performance. Simple preventative care can improve comfort, protect components from faster wear, and reduce the added fuel demand of a struggling AC. When to Seek Professional Advice If you notice persistent problems or suspect your cooling system isn’t performing as it should, it’s wise to have it evaluated by a qualified technician. For details on comprehensive car air conditioning services in Bunbury, including regas, inspection, and repair, visit our Air Conditioning service page. Getting your car's air conditioning serviced every 12 months means you often help prevent costly breakdowns now and in the future, keep passengers safe by helping to prevent the build-up of potentially harmful substances and a well serviced car air conditioner actually saves you money because it results in a reduction of fuel usage. Autotech Bunbury care about the environment and have Arctick Authorisation (AU36994) to reliably and responsibly conduct car air conditioner regas, servicing, repair or inspection. Book your car air conditioning service with the experts at Autotech Bunbury today! Air conditioning FAQ 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 Autotech Bunbury.  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 Autotech Bunbury. 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 Autotech Bunbury, 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.

Do These Service Checks Before You Leave Bunbury As the festive season draws near and many of us in the Bunbury area begin planning road trips, it’s the perfect time to give your vehicle a thorough service check. At Autotech Bunbury, we emphasise that the holiday period brings unique driving conditions — hotter weather, heavier loads, and longer distances — meaning your car deserves extra attention before you hit the road.    Why a full service matters now Long‐weekend drives, packed cabins, coastal cruising or heading into rural South-West WA all place extra demands on your car. The summer months in Australia are prone to heat stress, stronger UV exposure, and seasonal weather changes. According to the Bureau of Meteorology (BOM), summer is also a period for increased thunderstorms, heatwaves and unstable weather-patterns. A well-timed servicing ensures that minor issues don’t escalate mid-trip, and you leave home confident your car is ready for the extra load, the heat, and the journey ahead. Key areas to check Cooling system & air conditioning 
The hot climate of a South-West WA summer means your engine and cabin comfort are on full throttle. A properly serviced A/C system prevents fatigue and discomfort, and a fully functioning cooling system protects the engine. Battery & electrical system 
Heat affects battery performance; if your car has been sitting or the battery is more than three years old, servicing or testing it is wise. At Autotech Bunbury in Bunbury, we routinely test and condition batteries as part of our service programs. Tyres, wheels & alignment 
 A heavily laden vehicle or towing a trailer amplifies the importance of correct tyre pressures, tread depth and wheel alignment. Poor alignment can increase wear, fuel consumption and risk of blow-out under heat stress Fluid levels and filters 
Oil, coolant, brake fluid and air filters all play vital roles. Heat accelerates breakdown or contamination of fluids, so they must be correctly maintained. During a road trip you don’t want to face avoidable issues because a filter was clogged or a fluid degraded. Lights, wipers and visibility 
Long daylight hours, glare off sand and water, and seasonal showers demand good lighting, clean windscreen surfaces and reliable wipers. If your holiday route includes coastal fog or late afternoon drives, these checks are even more important. Brakes, suspension & under-carriage  
A fully loaded car or one towing a boat/trailer places extra stress on brakes and suspension. Ensure the components are sound, and that there are no underlying wear issues that could compromise control while driving on rural or winding roads. The added bonus of expert servicing Choosing a full service at Autotech Bunbury means more than quick checks — the team in Bunbury are backed by national standards, use up-to-date diagnostic systems and offer a nationwide warranty on their work. That means peace of mind not just locally, but for your entire trip. Planning your trip: service + strategy Start your service well ahead of departure - don’t leave it to the last minute. While our team in Bunbury can often accommodate short-notice appointments, a booked slot ensures calibrations, inspections and any required repairs are handled without rush. Also, factor in your load: extra passengers, luggage, possible towing, and climate control all draw on your vehicle’s systems. A service tailored to heavy-load travel will make a real difference. Referring to BOM forecasts before you depart adds another layer of preparedness — anticipate heat-spells, thunderstorms or heavy traffic and plan for rest stops, shaded parking and breaks. This Christmas, let your car be part of the celebration rather than the disruption. By giving your vehicle a full service at Autotech Bunbury in Bunbury, you’re not just being responsible - you’re investing in a smoother, safer, more comfortable trip for everyone on board. And don't forget that Autotech Bunbury are an RAC contractor and offer a Towing and Recovery Service which will remain available throughout the Christmas Holidays... Whether you’re heading towards the coast, the hinterland or simply enjoying family time nearby, your car’s condition matters…
