How to Remove Air-Conditioning Units

Put on heavy work gloves to protect your hands. These also help you get a better grip. Lay down an old towel on the floor under the unit to catch falling debris and prevent scratches to the floor if the unit slides out too quickly.

Unplug the air conditioner and wait a few minutes to ensure that all electrical power has been disconnected. Any lights on the unit should turn off and the fans should stop running. Examine the unit from inside and outside, if possible. Look closely for screws on the front trim. If the unit is too small for the hole or was improperly installed, there may be caulk along the edges.

Use the screwdriver to scrape away any caulk along the edges of the unit. Don't gouge the walls if you plan to replace the unit.

Unscrew the front trim around the unit, if it's screwed on. If your unit doesn't have any visible screws, the trim should snap off easily. If you meet resistance, check your manual to ensure there are no hidden screws. After the trim has been removed, the air conditioner may start to slide forward, so grip it tightly as someone else removes the trim.

Slide the unit slowly forward onto the floor. It will most likely be extremely heavy. The hole left in the wall can house a new unit or be closed off with drywall and planks of wood. Talk to a professional if you choose to close the gap in the wall to ensure proper coverage and insulation.
