How to Pull a Vacuum and Charge a Cars A/C System with Refrigerant

In this video I cover how to pull a vacuum and recharge your cars air conditioning system. We had just changed out the A/C Compressor on a Subaru Impreza that was on its way to failing and decided to do a separate video for correctly adding refrigerant.

Here's a link to the Video where we replace the A/C Compressor:

An important but often overlooked aspect is checking the high and low pressure vs Ambient temperature to check for a full charge, I cover this as well in this video. I also cover how the new cans of refrigerant have a check valve in them and are not pierceable. You must either use a special valve with these cans or manipulate the valve so that the flow remains open.

Having a good working A/C in the summer is important! But. it's also as important to have a good A/C/ compressor during winter. Defrosting your windshield relies on the A/C compressor to dehumidify the cabin air so it can effectively defrost your windshield!
