Hello!
Short answer: If you replaced the condenser *only*, you should add back 1.5 oz. or so into the condenser inlet OR carefully through the low-side as you are charging it back up. If you have any idea how much came out during reclaiming/recycling add that amount back in as well.
If you did things in a more through manner and have the money it is also best to replace the receiver drier/accumulator assembly along with the condenser. In this situation add back 2 oz. plus whatever you might have lost during reclaim/recycle.
As you recharge: Listen carefully for noise coming from the compressor as it cycles in and out. You may find you need to add a *small amount more*. As in a 1/2 oz. to 1 oz. to quiet things up. But more IS NOT better. Don't overdo it. You should only do that if the compressor is noisy and wasn't noisy before the repair. If you have other leak points in the lines and had lost lots of refrigerant and PAG oil from those leaks you may need to add a bit more.
Additional details: Why consider replacing the receiver drier/accumulator? Generally, it is considered a good idea to replace the receiver driver/accumulator anytime an a/c system has been opened to atmosphere for a while. This is because there is a desiccant bag inside of the part which pulls out moisture and helps prevent the formation of acids and corrosion inside of the a/c system. Exposure to air and moisture will make it less effective. Additionally, this is why it is mandatory to pull down an a/c system under a vacuum for at least 15 minutes (30 minutes is what was taught back when I was trained), close the gauge valves, and let it sit for 15 minutes. Pulling it down under vacuum and letting it sit afterwards does two things - gets out as much oxygen and moisture as possible, and if the vacuum in the system drops as it sits with the gauge valves closed you know you have another leak to fix someplace.
