Air conditioners are among the most expensive things you move, and the easiest to damage. A rushed removal can lose the gas, bend copper pipes or crack the outdoor unit. Here is how to shift an AC safely – split or window – when you move home or office.
Always use a trained AC technician
Removing and installing a split AC involves refrigerant gas and electrical work. Ask your movers whether they have their own AC technician, or book a reliable local one for both houses.
Shifting a split AC: the right way
- Pump-down: the technician runs the AC in cooling mode and closes the service valves so the gas is collected in the outdoor unit. This saves the gas for re-use.
- Switch off power and disconnect the electrical wiring.
- Disconnect the copper pipes carefully and cap both ends so dust and moisture do not get in.
- Remove the indoor unit from its mounting plate and the outdoor unit from its stand.
- Keep the outdoor unit upright during transport – laying the compressor flat can cause problems.
Packing and transport
- Wrap the indoor unit in bubble wrap and a blanket; protect the plastic louvres.
- Wrap the outdoor unit and protect the fins at the back, which bend easily.
- Load units upright and strap them so they cannot slide.
- Keep remotes, screws and brackets in a labelled bag.
Re-installation tips
- Choose a shaded, ventilated spot for the outdoor unit.
- Use new copper pipe if the old one is too short or damaged.
- The technician should vacuum the lines before opening the valves.
- Test cooling and check for leaks before the technician leaves.
Window AC
Window ACs are simpler: unplug, remove from the frame, keep upright and protect the fins. Still, carry them with two people – they are heavy and awkward.
Frequently asked questions
Will I need a gas refill after moving?
Not if the pump-down was done properly and there are no leaks. If pipes were cut or left open, a refill may be needed.
Should I move old ACs to another city?
For very old or inefficient units, compare the cost of moving and re-installation with buying a new one.
