Furnace and A/C removal
Posted 17 July 2012 - 11:19 PM
Could someone please comment. Is it necessary to evacuate the freon from the system even though the A/C it's going to be reused.

The Evaporator Coils are inside the house, inside the Furnace Air Handler
How are you going to take either or both without disconnecting them ?

Start the system in COOL.
Once the suction pressure starts pulling down,CLOSE the high side valve.
When the low side gets to "0" psi quickly close the suction valve and DISCONNECT power.
Cut your copper refrigerant lines near the condenser and seal the cut lines with tape.
Same for the inside lines at the air handler.
When the unit has been re-installed add a filter drier to the high side tubing, pull a good vacuum on the lines and the A/H..
If no leaks are present,open the high side valve to release the captured refrigerant.
Then open the low side valve.
