In this video I will show you how I troubleshot my ac system. My ac was blowing hot and not cooling at all. My compressor was unable to clutch in. So I figured out why, and added some R134A to my system, which made it a little cooler.

ADDED KEY POINTS

1. Read the back of the can of R134A it tells you how to add the refrigerant properly. There is a specific way to hold it while adding.

2. Holding a can of R134 upright allows vapor to be taken into the low pressure suction side of the system. Which is what you want.

3. Holding a can of R134 upside down may allow liquid to flow into the low pressure suction side of the system. Which is what you do not want.

4. A compressor is not meant to compress liquids. Liquids do not compress, and could cause damage to a compressor if liquid gets into the compressor's cylinder. It should only compress a vapor.

5. Also you may be able to add the R134 can to the low side without jumping out the compressor. Sometimes the R134 can itself has enough pressure to make the compressor come on without having to jump it out at all.

6. I still prefer to make the compressor kick on, because I like to do it that way. Either way you do it try to focus on holding the R134 can properly to ensure you get vapor in the low side and not liquid. I hope that makes sense.

7. Buy an ac recharge system that has a long hose, and not like the setup I used. I could not hold the can in the most optimal position. I found my setup a little awkward.

8. I still think the best way to service an AC system is with professional equipment. Equipment that can recover, pull vacuum, charge accurately, separate and measure oil ( PAG), Check for leaks, and measure pressures correctly.

9. Understand that without proper equipment and using a DIY AC system in your driveway can end up costing you more in the end.
It is fairly easy to damage an ac system, without using proper equipment.

10. I chose to work on my own system because, I am fully aware of the risks involved. I have had a little training on ac systems, I don't consider myself an expert by any means, I am 609 and 608 certified (which doesn't mean much, anybody can pass the test and become 609 certified in no time)

Anyway thanks for your time and have a good day.
