Cooling & Heating · Ductless RelocationMini-Split Relocation
Mini-split relocation is a refrigeration job, not a carpentry one: the charge is pumped down into the outdoor unit, the lines are disconnected, the equipment is moved, and every flare joint is cut off and remade before the system is pressure-tested, evacuated and reopened. It is worth doing on a unit under about ten years old. On an older one, compare the quote with a new single-zone system at $4,000–$7,000.
Three situations bring most relocation calls. A renovation takes out the wall the head hangs on, or changes the room so the head now blows at a bed or a desk. The head sits on a problem wall, such as an interior partition with a pumped drain that keeps failing. Or the outdoor unit is exactly where the new deck, addition or walkway is going.
The refrigerant stays in the system during a move. With the unit running in cooling, the technician closes the liquid service valve and lets the compressor draw the refrigerant out of the indoor coil and the lines into the outdoor unit, then closes the suction valve and cuts the power. Only then are the flare nuts undone and the open lines capped against moisture. If the compressor will not run, the charge is recovered into a cylinder by an ODP-carded technician and weighed back in afterward.
Flare joints are remade, never reused. Copper hardens where it was flared and tightened, so each end is cut back to clean tube, deburred, flared again and tightened to the manufacturer's figure with a torque wrench. The line set itself is reused only if it reaches the new position without strain or kinks. Otherwise a new one-piece run goes in, since a brazed splice hidden behind line cover is one more joint to leak; AC line set replacement describes that work.
Length is the constraint people do not expect. Every model has a minimum and a maximum line length and a maximum height difference between the two units, all printed in its installation manual. The factory charge covers a set length, commonly around 7.5 metres, and a longer run needs extra refrigerant weighed in at a stated number of grams per metre. Moving the outdoor unit also moves its disconnect and circuit, which is work for a licensed electrical contractor under an ESA notification.
Relocation makes sense when
- The unit is under about ten years old and has had no refrigerant or board faults
- A renovation, deck or addition needs the wall or the ground the equipment occupies
- The head blows directly on a bed, desk or dining table
- A pumped drain on an interior wall keeps failing and an exterior wall is available
- The outdoor unit sits under a roof valley that buries it in ice and meltwater
How it works
We check the new wall for a drain route and the outdoor spot for clearances, measure the line length against the model's limits, and confirm what the electrical move involves. Send photos of both locations and the model number to start.
The charge is pumped into the outdoor unit, the lines and cable are disconnected and capped, and the equipment is taken down. During a renovation the units can sit sealed until the new wall is finished.
New flares are torqued, the lines are held under nitrogen pressure, and the circuit is pulled to a deep vacuum that must hold with the pump isolated. Then the service valves are opened, any added charge is weighed in, both modes are run, and the old wall opening is sealed against weather.
Common questions
Can I move the indoor head myself and have you reconnect it?
You can take down a mounting plate and patch a wall, but the refrigerant side belongs to a certified technician. In Ontario anyone opening a refrigerant circuit needs an ODP card, and releasing refrigerant is prohibited. Undoing a flare on a charged system empties it. Can I install a mini-split myself in Ontario explains where the line sits.
Will relocating the unit void the warranty?
Manufacturer warranties cover parts that fail from defects, and most require installation and service by a licensed contractor. A properly done move does not change that, though it will not restart or extend the coverage either. Keep the invoice showing the pressure test, vacuum and charge figures with your original paperwork, and check the terms on your registration card.
Can the head go on an interior wall?
Yes, with two costs. The line set gets longer, which may mean added refrigerant, and the condensate can no longer fall by gravity to the outside, so it needs a condensate pump or a sloped drain to a plumbing connection. Pumps work, but they are the part most likely to fail later, so an exterior wall is the first choice whenever the room allows it.
How long is the system out of service?
A simple move of one head or the outdoor unit is usually done in a day, including the pressure test and the vacuum, which cannot be rushed. During a renovation it is often two visits: one to pump down and remove the equipment before demolition, and one to reinstall when the new wall is closed and painted.
Where should the outdoor unit go?
On a wall bracket or stand above the snow line, clear of the roof drip line, with the airflow clearances from the manual, and away from bedroom windows, yours and the neighbour's. Municipal noise and setback rules can apply in narrow side yards. AC unit placement rules in Ontario covers the distances.
