AC RECHARGE

[bigblue37]

I have used the harbor freight vacuum pump and manifold gauges in the past several times with excellent success. Like others have said, make sure you pull a vacuum first and let the system sit for a while to ensure there are no leaks. You will also need to pull a vacuum if the system got any air in it whatsoever. Our atmospheric air has moisture in it, which will cause the system to overheat and destroy components. Prior to owning my own ac tools, I’ve used Meineke to service my systems. They’re middle of the road pricing. An important note is that if adding refrigerant you will want to 1. add oil if you replaced any components, and 2. Ensure you add the correct amount of refrigerant, which is usually calculated in ounces. Never trust the built in gauges on the bottles of refrigerant.

Eric the car guy has several videos on YouTube with step be step instructions on how to pull the vacuum and add refrigerant. Recommend watching them if you’re doing it yourself.
