Moving season is in full swing: between July and September, nearly half of all home moves in France are concentrated in this window. And for the past two years, a new question has slipped in among the boxes: "My air conditioner — do I take it or leave it?"
It was almost never asked before 2025. An air conditioner used to be a rare piece of equipment, often installed by the landlord and considered part of the property. But with VAT on reversible air conditioners cut to 5.5% and the residential installed base exploding, hundreds of thousands of households now own a wall-mounted split unit that cost €2,500 to €4,000 and is less than three years old. Leaving it behind stings.
The honest answer is nuanced: it's technically possible, it's legally regulated, and it only makes economic sense about half the time. Let's break it down.
First: who owns the air conditioning?
That's the starting point, and on its own it settles a great many situations.
You're an owner-occupier and you're selling
The indoor and outdoor units are fixed to the structure, connected by refrigerant lines that are either embedded in the wall or run in trunking, with holes drilled through the masonry. French civil law classifies this type of equipment as an immovable by destination (Article 524 of the Civil Code): it is deemed to form part of the sale unless there is an explicit statement to the contrary.
In practical terms: if you want to take your air conditioning with you, it must be written in black and white in the preliminary sale agreement, stating that the property is sold without the air conditioning system, and ideally describing the condition in which the walls will be left. A buyer who discovers at the key handover that the split units have vanished and that three 65 mm holes are gaping in the façade has a perfectly valid grounds for dispute.
Conversely, a portable single-block air conditioner on castors remains a movable item: it leaves with you, no argument.
You're a tenant
If you installed the air conditioning yourself, with the landlord's written consent, everything depends on what that agreement says. In the absence of a clause, Article 7 f) of the Act of 6 July 1989 lays down the principle: alterations made by the tenant become the landlord's property without compensation at the end of the tenancy, unless the landlord requires them to be reversed.
In other words, if the landlord asks nothing of you, you cannot claim any compensation — but nothing stops you from negotiating their consent to remove it, provided you restore the walls to their original condition. This is exactly why the initial installation agreement should always specify what happens to the equipment at the end of the tenancy. A registered letter with acknowledgement of receipt at the time you request permission to install, carefully kept, is worth more than ten verbal conversations.
You're in a co-ownership building
Even as you leave, remember that the outdoor unit occupied a common area or an element visible from outside, authorised by a general meeting. Dismantling doesn't require a new general meeting, but restoring the façade (filling holes, touching up paintwork, removing the wall brackets) is very much down to you. The managing agent can legitimately ask for it.
The step 90% of homeowners overlook: refrigerant recovery
This is where the subject stops being a moving problem and becomes a regulatory one.
An air-to-air heat pump contains refrigerant — nowadays almost always R-32 in recent appliances, sometimes still R-410A in equipment more than five years old. These fluids are fluorinated greenhouse gases covered by European Regulation (EU) 2024/573 (known as F-Gas III) and, under French law, by Articles R. 543-75 et seq. of the Environmental Code.
Three rules follow from this, and they admit no exceptions:
- Venting is prohibited, i.e. letting the refrigerant escape into the open air by unscrewing the fittings. R-32 has a global warming potential (GWP) of around 675: the 1.2 kg contained in a typical split unit is equivalent to roughly 800 kg of CO₂. R-410A goes up to a GWP of 2,088.
- Only an operator holding a certificate of capacity issued by an approved body (I.Care, Cemafroid, Bureau Veritas, etc.) may handle these fluids, with staff holding an aptitude certificate of the appropriate category.
- The refrigerant must be recovered into a dedicated recovery cylinder, then either reused in the same installation or handed over to a treatment channel, with traceability via an intervention record.
Non-compliance is no token matter: deliberate venting carries a fine of up to €75,000 and two years' imprisonment under environmental policing offences. In practice, an individual acting alone will rarely be prosecuted — but a company that agreed to do it would be running a very serious risk, which is why no reputable refrigeration engineer will offer to "just snip it off quickly".
"Pump down": the clean method
In practice, the professional doesn't always recover the refrigerant into a cylinder. On a small-capacity split unit in good condition, they perform a transfer of the charge into the outdoor unit, commonly known as a pump down:
- they close the liquid valve on the outdoor unit;
- they run the appliance in cooling mode for a few minutes, the compressor drawing all the refrigerant from the lines and the indoor unit into the condenser;
- they close the gas valve, then switch off the power supply.
All the refrigerant is then stored in the outdoor unit, which can be transported as it is. It's clean, quick, and it means the original charge can be reused at the new site. That said, the circuit must be leak-tight and the compressor functional: an appliance that's already leaking can't be "pumped down" properly.
A three-way manifold gauge set and a vacuum pump remain professional tools: this isn't weekend DIY, and improvising usually costs you the compressor.
The real cost of moving an air conditioning system
Here are the ballpark figures observed in 2026 for a simple wall-mounted split unit (one indoor unit, one outdoor unit), excluding special cases.
| Service | Price range incl. VAT |
|---|---|
| Removal with refrigerant recovery (pump down) | €200 – €350 |
| Removal with cylinder recovery + traceability | €300 – €500 |
| Filling holes and touching up the façade | €80 – €250 |
| Reinstallation at the new site (new lines, vacuum pull, commissioning) | €600 – €1,200 |
| New refrigerant lines (effectively mandatory) | €25 – €45 / metre |
| Top-up charge if refrigerant has been lost | €60 – €120 / kg |
| Realistic total, single split unit | €1,000 – €1,800 |
A multi-split system (three or four indoor units) quickly climbs to €2,200 – €3,500, because each line has to be removed, replaced and purged again.
The awkward arithmetic
Set that total against the price of a brand-new installation. A 3.5 kW reversible single-split unit, installed in 2026 with VAT at 5.5%, costs between €1,900 and €2,900 depending on brand and complexity. So moving yours costs between 50% and 80% of the price of a new one — for an appliance that will have lost a few years of warranty and whose leak-tightness you no longer fully control.
Rule of thumb used by most installers: beyond five years of age, or for an entry-level appliance, moving it isn't worth it. Under three years, on mid-range or high-end equipment (Daikin, Mitsubishi Electric, Toshiba, Atlantic), it becomes worthwhile — especially if the distances between units are comparable from one home to the other.
And don't forget the hidden variable: the added value on resale or re-letting. A home fitted with a working reversible air conditioner rents and sells better, particularly in south-eastern France, in the Île-de-France region and in upper-floor flats. Leaving the equipment behind and putting a value on it in negotiations sometimes pays better than carting it away.
The five technical points to check before saying yes
Even once the decision to move the appliance has been made, it can run into concrete constraints.
1. The length of the refrigerant lines. Every model has a maximum permissible length (often 15 to 25 m) and a maximum height difference between units (generally 8 to 12 m). If your new home requires 20 m of line where you previously had 4, the refrigerant charge will have to be adjusted, or the appliance may simply become unsuitable.
2. Capacity relative to the new volume. A 2.5 kW unit perfectly sized for a 30 m² living room with a 2.50 m ceiling will be woefully inadequate in a poorly insulated 45 m² loft conversion. Sizing has to be redone; it doesn't travel with you.
3. The condition of the outdoor unit. Bent condenser fins, a rusty casing, a noisy fan: transport always makes existing problems worse. A thorough clean beforehand with condenser fin cleaner and a visual inspection will spare you nasty surprises at recommissioning.
4. Reusing the lines. Technically, removed copper pipework can be reused. In practice, no serious installer does it: the flares have been worked, the refrigeration oil may have been contaminated, and the commissioning warranty is void. Budget for new lines.
5. Authorisation at the new site. Co-ownership rules, local planning regulations, protected heritage areas: the same rules as for a new installation apply. Check before dismantling, not after.
What happens to the 5.5% VAT rate in all this
A frequent question since the reduced rate came into force for reversible air-to-air heat pumps: does the service of moving an existing air conditioner qualify for the 5.5% rate?
The tax logic behind the reduced rate rests on the supply and installation of a high-performance heat-generating appliance in a home completed more than two years ago. A simple removal, or the reinstallation of equipment you already own, comes in principle under home improvement works at 10% VAT, or even 20% for the removal labour alone, depending on the classification the company applies.
In short: don't count on 5.5% for a relocation. Ask for the rate applied to be spelled out on the quote, line by line, and don't hesitate to ask the company on what basis it is applying it. Positions vary from one installer to another, and the tax authorities reserve the right to rule — it's the company that carries the tax risk, not you, but a vague quote is always a bad sign.
Special case: the tenant leaving with a portable air conditioner
All of this machinery falls away if your equipment is a portable single-block air conditioner with an exhaust hose out of the window. It unplugs, it goes in the van, there's no refrigerant to recover and no façade to patch up.
Two useful habits for transport:
- carry it upright, never lying down: the compressor oil can migrate into the circuit and damage the machine on start-up. If you've had to lay it flat, wait 12 to 24 hours before switching it back on;
- empty the condensate tray completely before the journey.
And at the new place, if the window isn't the same configuration, a window sealing kit is what makes the biggest difference to this type of appliance's real-world performance: without a proper seal around the hose, you draw hot outside air back in and efficiency collapses by 30 to 40%.
The checklist before you unscrew anything
- Check who owns the equipment (preliminary sale agreement, tenancy agreement, landlord's written consent).
- Obtain written agreement from the owner or buyer if you're taking the appliance with you.
- Request two quotes from companies holding a certificate of capacity — the number appears on the quote and can be verified on the Cemafroid website.
- Have removal and reinstallation quoted together: it's almost always cheaper than two separate jobs with two different contractors.
- Insist on the intervention record stating the type of refrigerant, the quantity handled and the recovery method. That's your proof of compliance.
- Check technical compatibility with the new home before dismantling.
- Keep the manufacturer's manual and the original invoice: they determine whether the warranty can be maintained and ensure correct settings at recommissioning.
- Get hold of some exterior filler and a set of caps for the holes left in the façade, if making good is down to you.
And if you leave the equipment behind?
That's often the best choice, and it deserves to be turned to your advantage rather than merely endured. Three simple steps:
- Document the installation: invoice, year of installation, make and model, date of the last service, servicing certificate if the equipment exceeds 4 kW (the five-yearly obligation under Article R. 224-59-1 of the Environmental Code applies to air conditioning systems above 12 kW, and it's good practice below that). A tidy file reassures buyers and strengthens your hand.
- Have it serviced before the check-out inventory: filters cleaned, condensate tray drained, outdoor unit clear of obstructions. A set of replacement filters left on site heads off an awkward remark.
- Mention it in the listing: "Reversible air-to-air heat pump installed in 2025, regularly serviced" is a measurable selling point in a market where summer comfort is becoming as decisive a criterion as the energy performance rating.
The instinct of "I paid for it, I'm taking it" is understandable but rarely the most rational. On a recent, mid-range appliance, with a new home that's technically compatible and a company handling removal and reinstallation as a single job, moving it makes sense. In all other cases, the arithmetic points towards selling the home fully equipped and installing new equipment that's better sized, under warranty and at the reduced VAT rate.
And whatever the situation: nobody unscrews a refrigerant fitting themselves. That's not a precaution on principle, it's an environmental offence — and a dead compressor.
