Need to remove old central air unit
 

:D I have purchased a new central air unit and I need to remove the old central air unit. How do i depressurize the compressor?

Today, you need a licensed pro with recovery equipment. The days of 'lettin it fly' are over.

can 't you tell him how to do it, without loosing any freon? Just do a condenser pump down? Is that not legal either?

install gauges, back seat (close)Liquid line, close off suction side 1/4 to 1/2 way. operate condenser. the gauge preasure readings wil steadaly drop toward 0 psi.when you get to 0psi close off the suction side quickly the rest of the way and shut off condenser. your done

If you can, keep the unit and bring it to a junk yard if you have one near by. You won't get rich but you can make a few bucks on the copper etc in the unit. Mind you, if you have a pick up truck that makes it easier and less hassle.
