Uninstalling a Split Air Conditioner

The split type conditioner has outside and inside units that are not connected to each other, which make the problem of uninstalling a split air conditioner that much simpler.

Next, unscrew the copper pipe which connects the inside and outside units. It is important to put a bucket or tray underneath the units in order to catch spills from the refrigerant. Another solution would be to "bleed" the refrigerant before removing.

Unscrew the inside unit from the wall, and place on a table with newspaper or similar. Remove any wires or parts that might be needed. Leave to empty itself of refrigerant.

After removing the split air conditioner from the room, you may be aware that there is a hole in the wall of your room; if you are intending to replace the split AC unit with another, this hole can be used for the installation. If not, you will need to block this hole with builders’ putty or cement.
