Sometimes your AC system might not be working as good as it should. Sometimes this is due to a low system charge. In this video I walk you through the steps of topping off your AC system to get it to cool better.
Keep in mind the pressures in this video may not be the same as what you might see on your vehicle. The pressures are dependent on the system your working on, the relative temperature, and relative humidity.
**Note** This is not likely to work in all situations. Also, be sure and follow safe procedures when working with refrigerant.

Some of you may note a different cameraman. Don’t worry, Brian is still working with me, he was just off when we shot this video.
