Keeping your vehicle’s car air conditioning system at optimum condition is very important in order to maintain the comfort of long drives, especially in warmer months.
Diagnosing the air conditioning problems early can save a lot of time, money and frequent visits to an auto electrician service centre in Sydney. The key is to identify the problem through certain common signs that are noticeable.
In this article, we have compiled general information about some common problems you may encounter and how to troubleshoot them effectively.
Common Air Conditioning Problems and How to Identify Them
Understanding such problems beforehand can save you hefty time and effort. These issues range from simple fixes like recharging the refrigerant to more complex problems like faulty compressors or electrical failures. Each symptom your car exhibits can give you clues about the underlying problem. For example, if your car is blowing warm air instead of cold, it might be due to low refrigerant levels, a common issue in many vehicles. On the other hand, strange noises or a complete lack of air coming from the vents can indicate more severe problems.
Refrigerant Leaks
Refrigerant leaks are a fairly common issue in most vehicles. Low refrigerant levels lead to drastic reductions in cooling efficiency and reduce its overall performance.
Signs to look out for – Warm air blowing from the vents, an A/C system that frequently cycles on and off, or visible dye (if previously added) under UV light.
In such cases, use a UV dye kit or an electronic leak detector to identify leaks. Once the leak is located, a qualified car air conditioning servicing expert can repair it, evacuate the system of old refrigerant, and refill it with new refrigerant.
Faulty Compressor
A faulty compressor can lead to little to no cooling as it is responsible for pressurising and circulating the refrigerant throughout the system.
Signs to look out for – Lack of cold air, unusual noises from the A/C unit, or the compressor clutch failing to engage.
If you notice any of the signs, check the compressor clutch and electrical connections using a multimeter. If faulty, the compressor may need replacement or repair by a professional.
Clogged Condenser
The condenser is generally responsible for releasing the heat from the refrigerant, but it can become clogged or damaged over time.
Common signs you can look out for include – Reduced cooling efficiency, visible condenser damage, or debris blocking the airflow.
Inspect the condenser visually and clear any debris obstructing airflow. In case of severe damage, consider replacing the condenser entirely. You can get in touch with a professional for this.
Electrical Issues
Electrical issues can happen anytime and only upon inspection, you know if basic fixing is required or complete replacement of the component is. Blown fuses, malfunctioning pressure switches, or faulty control modules, can prevent the A/C system from working.
A/C system not turning on, compressor clutch not engaging, or fuses blowing frequently are some of the common signs.
If encountered with any of these, use a multimeter to diagnose electrical faults. Replace blown fuses and faulty switches. Complex electrical issues may require the assistance of a professional auto electrician.
Worn Out Parts
All vehicle parts have a limited lifespan, and it is essential to replace them before they work out completely. Aging or faulty parts like the expansion valve, orifice tube, or the A/C belt can hinder system performance.
If you have been faced with reduced cooling efficiency, poor airflow or compressor failure, then seek professional help for intricate repairs. They will thoroughly inspect and replace worn-out components such as the expansion valve, orifice tube, or belts.
