Disconnecting and Moving a Ductless Air Conditioner

Ductless air conditioners are high-efficiency cooling appliances that work in a single room or an open space encompassing two or more rooms, such as a den adjacent to a kitchen. There is significantly less energy loss because the system does not move cool air through ducts, where energy is wasted. A ductless air conditioner works with an outdoor condenser, which is routed directly through the wall where the AC unit is installed. With most systems, there is a small hole in the wall behind the AC unit for routing the hoses and electrical cord outdoors.

Instructions

- 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.
- 10
  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.
