Many customers claim that their "A/C is not getting cold" when the actual issue is too little airflow from the vents. When you take your vehicle in for service, try to demonstrate the problem so the shop has a better understanding before they start the diagnosis.

Small leaks in the A/C refrigerant system are very difficult to find. To make finding leaks easier, a shop should add a special leak detection dye to the refrigerant every time the system is recharged.

As with most computer controlled systems in modern vehicles, the climate control system may need occasional software updates to address various issues. A quality shop will check with the manufacturer to see if there are any Technical Service Bulletins (TSBs) related to the problems you're having and will upgrade the software when possible.

If your A/C is providing little cooling or none at all, it may be that the system is leaking A/C refrigerant. As the system becomes low on refrigerant, you may hear the A/C compressor cycling on and off when the A/C is turned on.

Adding refrigerant to a poorly functioning A/C system without first diagnosing the problem may result in overcharging. This has been known to cause damage to the A/C compressor, resulting in a very expensive (and avoidable) repair.
