- 1). Contact an electrician to discuss wiring for the new air conditioner location. You can disconnect and move the unit yourself, but a licensed electrician should be hired to install wiring at the new AC location outside the home. In some locations, only a licensed electrician may install new household wiring.
- 2). Shut off the circuit breaker for the ductless air conditioner. Disconnect the condenser and drain hose clamps from the outside unit with a screwdriver or a wrench, if the clamps are attached with nuts and bolts. You can see the connection points where the hoses enter the house through the exterior wall.
- 3). Remove the terminal box on the condenser with a screwdriver, and disconnect the electrical cord from the terminals inside. Use a screwdriver or wrench, depending on whether the terminals are attached with screws or nuts threaded onto bolts.
- 4). Remove the wall-mounting screws on the AC unit inside the house. The unit pulls off the wall and can be lowered to the floor.
- 5). Disconnect the hoses from the back of the AC unit.
- 6). Loosen the two screws on the electrical terminals, and disconnect the two wires from the back of the unit.
- 7). Prepare masonry compound according to the package instructions, and fill in the exterior wall hole with the material and a trowel. Let the compound dry overnight.
- 8). Patch the hole in the interior wall with spackling compound. Use a putty knife to create a smooth repair on the wall. Let the compound dry overnight before you paint over it.
- 9). Move the outdoor condenser unit to the new location with the help of a friend. The unit is heavy and bulky. Reconnect the condenser and drain hoses to the unit.

Place the indoor AC unit in the new location next to the exterior wall where the condenser is now located. - 11
Shut off the circuit breakers to the house before you drill. You do not want to risk drilling into a live wire. - 12
Cut a 1-inch diameter hole through the wall with a power drill and masonry bits. Work slowly to prevent cracking the masonry or brick. - 13
Route the condenser, drain hoses, and electrical cord through the hole, and reconnect to the back of the indoor unit. - 14
Use a caulk gun to fill the gap in the exterior wall hole around the hoses and wires with outdoor caulk.
