How to Uninstall a Split Air Conditioner 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. This type simply fixes to the wall with a few screws and a couple of holes. However, there may come a time when the unit ceases to function, either due to age, electrical problems, or debris buildup, and it may be necessary to get rid of it. Or, it may be a good idea to uninstall the AC unit during winter time. Regardless of your reasoning, it is best to get an idea of how you can complete this project safely before you start.
Step 1 - Disconnect the Power
The split type conditioner has outside and inside units that are not connected to each other, which make the problem of uninstalling one that much simpler. However, the most important thing to do before removing 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. It is not safe to uninstall any electrical appliance until this is done.
Step 2 - Take the Inside Unit Down
Next, unscrew the copper pipe which connects the inside and outside units. Put a bucket or tray underneath each side in order to catch spills from the refrigerant or "bleed" the system before removing.
Then, unscrew the inside unit from the wall, and place on a table with newspaper or something similar. Remove any wires or parts that might be needed, and leave it to empty itself of refrigerant.
Step 3 - Remove the Outside Unit
Move to the outside unit. This is sometimes placed higher than the inside one, so be sure to proceed carefully if using a ladder. Remove the pipes and wires from the unit, and unscrew it from the wall (or lift down if it is resting on brackets). Again, remove any parts or pieces you might need to, and take it inside to be empty.
Step 4 - Patch Hole if Necessary
After removing the split air conditioner, you will notice that there is a hole in the wall; if you are intending to replace the unit with another, this hole can be reused for the new installation. If not, you will need to block this hole with builders’ putty or cement.
Whenever you are uninstalling appliances which have electric current, or toxic liquids, it is always best to get the help of a professional. So, when it comes time to dispose of your old split AC, contact your local sanitation department for directions on the proper procedure to follow.
Always make sure safety is first in your mind! Don’t stand on chairs or on tip-toe to reach units. Use a ladder and have a friend nearby if it is out of reach. Again, always ensure that the electricity is disconnected before beginning to remove the wires or unscrew the units. If you feel unsure about anything involved in this process, don't hesitate to call a professional instead.
