When your vehicle air conditioning stops working properly, it can make your journey uncomfortable. A professional should look at your AC to not only refill the refrigerant but find out why the system is not working and what options there are to fix the issue. This can help to know what to expect.
Prior to your appointment
Write down what symptoms you’re noticing. Are you getting hot air straight away, does it only get cold when driving? Or does it just stop working after a few minutes. Is the airflow poor or blowing strongly but not cold? Any strange noises such as clicking, rattling or squealing. Any strange smells?
If you’re getting any warnings on your dash or the temperature is rising, let them know. Provide them with the year make and model of your vehicle and if you have any service history. If your AC issues started after you had another repair or accident, let the garage know.
1. Review Symptoms/Initial Checks
The technician will usually ask you questions to start with. They will also probably switch your AC on to get an idea of what the issue is. They may carry out some basic checks such as checking the temperature from vents, fan working, compressor engaging, checking for visual damage and checking the correct fuses/switches. If the airflow is poor then there are different issues that could be causing this than if the airflow is strong but not cold.
Not always will the initial symptoms tell you what the problem is. There could be many issues such as a refrigerant leak, electrical issues, blocked airflow or mechanical issues. Further tests may be needed.
2. Diagnose
Depending on your vehicle and symptoms they may perform various tests. This can range from checking pressures, checking hoses and connections, electrical testing, checking the condenser and cooling fans or checking for signs of a leak. Some specialist equipment may be required to find certain leaks or if they’re using new refrigerants.
A professional should carry out the correct process and use the right equipment. They should also not be letting refrigerant escape into the atmosphere. The system should not be opened up unless necessary as it’s under pressure.
3. Explanation/Cost
Once the tests are done ask them to explain what they found and how this is causing your symptoms. Ask for a clear breakdown of costs. This should include what they recommend fixing, parts, labour, diagnostic and anything else. If there’s more than one option ask how much difference it would be to have each one. How reliable and suitable they are.
For example, if there’s a leak in the seal they may need to do something different to if there’s damage to the condenser or compressor. If there’s low refrigerant ask if they found a leak and what should be done. If they just top it up it’s unlikely to be a long term solution.
4. Fix and Check
They may need to replace a part, fix a leak, resolve an electrical issue or unblock the airflow. Depending on what they found they will fix it. Once they’ve fixed it they should check the system works and that there are no issues caused by the repairs. Ask what has been done and if there are any other issues to keep an eye on.
If they need to order a part ask when they can get it. It’s best to get a realistic time frame.
What to do in between
Keep your cabin air filter in good condition. Be aware of any changes in cooling. Don’t ignore any strange smells or noises. Always follow the manufacturers guidelines. Don’t use any additives or recharges unless you know they’re suitable. If you’re getting any smoke, burning smell or overheating stop safely and get a professional.
