Furnace and A/C removal

Recommended Posts


My friend is replacing his furnace and a/c with a new one. He wants me to have the old one, but he said I would need to hire a license tech to remove it from his house and evacuate the system. I thought evacuating the system's freon is unecessary since I'm reusing the A/C and not taking it to the dump. I thought it would benefit me to keep the freon within it.

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.

A split system needs to be evacuated of gas before moving. Take the copper and everything because his new system gonna need differing size of copper anyway.

The Compressor and Condenser Coils are outside of the house...

The Evaporator Coils are inside the house, inside the Furnace Air Handler

How are you going to take either or both without disconnecting them ?

most of the refrigerant can be "captured" inside compressor. are you sure its worth the expense to move to your home? the system is being replaced for a reason.

Install your refrigerant gauges on the condenser.

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.
