R22 is worth about $20 -$25 per lb

A 2 Ton outdoor air conditioner requires 3 pounds and 14 ounces of R22 refrigerant.

The general rule amount that can be estimated is in the 2-4 pounds per ton of cooling for your system. For example: 3-ton AC or Heat Pump with a 35 foot lineset will need a total of approximately 6-12 pounds of refrigerant, to fully recharge from empty.

A air conditioning man can recover almost all of it. Gas is fully reusable.

yes it is! After all you don’t just want to release Freon into our atmosphere!!! We really would like to hang on to our Ozone layer

If you're in the USA the EPA requires it to be recovered. Plus it's dangerous to do the job with the system under pressure.

Be sure to replace the AC compressor and the freon liquid in your air conditioner before installing it. If you don't do this, you may endanger the filter at the air conditioner. The fact is that the old freon will work poorly and clog the filter and because of this you will have to change the filter often. If this is not done, then get ready to spend money. I once decided not to change the freon and as a result, my filter got clogged and I had to change a few more parts besides the filter. I ordered the parts for the air conditioner from here https://www.airconservicingsingapore.com... and began to repair it instead with his friend. Now I always keep an eye on freon.
