How to Uninstall a Split Air Conditioner


A wall-mounted split air conditioner is considered one of the best ways of cooling a room without damaging windows or doors. The split type air conditioner simply fixes to the wall, with a few screws and a couple of holes. However, there may come a time when the split conditioner ceases to function, either due to age or dirt, and it may be necessary to uninstall the split air conditioner.

Sometimes, it is also an idea to uninstall the AC unit during winter time.

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.

The most important thing to do before uninstalling any AC unit is to ensure that the power supply is turned off—unplug it at the mains, or take off the wires from the connection box as the first job. It is not safe to uninstall any product without this being done.

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.

Move to the outside unit. This is sometimes placed higher than the inside unit, so be sure to remove carefully if using a ladder. Remove the pipes and wires from the unit, and unscrew from the wall (or lift down if it is resting on brackets. Remove any parts or pieces desired, and take inside to be emptied or 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.

Safety First

Whenever you are uninstalling appliances which have electric current, or toxic liquids, it is always best to get the help of a professional engineer or electrician. When getting rid of the old split air conditioner unit, remember that these items contain refrigerant, which means that it is necessary to dispose of it by calling the local sanitation department first. 

However you wish to uninstall the split air conditioner, take as many safety precautions as you can: don’t stand on chairs, or on tip-toe to reach units. Always use a ladder if it is out of reach. Always ensure that the electricity is disconnected before beginning to remove the wires or unscrew the units. If you feel unsure about this aspect of uninstalling a split air conditioner, it is best to locate an expert and hire them to uninstall the unit for you.
