Air-conditioning technician visit: how to prepare your home, and what you are left with afterwards

4 Nov 2026 - 04 min read

You have booked your air conditioner service. On the day, a few minutes of preparation are enough for the visit to run without wasted time: a clear path, access to the outdoor unit arranged in advance, the right documents to hand.
This guide goes through, in order, what helps before, during and after the air-conditioning technician's visit, whether you live in a flat or a house.
When booking: the right information
The more precise the booking, the better the technician can plan. Remember to state:
- the number of units: how many indoor units (the appliances in the rooms) and how many outdoor units. The price depends on it: €130 including VAT for one indoor and one outdoor unit, €40 per additional indoor unit, €70 per additional outdoor unit;
- where the outdoor unit is: balcony, terrace, garden, courtyard, façade or roof. A unit mounted high on a façade or sitting on a roof sometimes needs special access, which is best mentioned from the start;
- the make and model, if you know them: they appear on a label, often on the side of the indoor unit or on the outdoor unit's rating plate;
- the age of the property: in France, VAT is 10% for a home completed more than two years ago and 20% otherwise, as set out on service-public.fr.
You choose a morning or afternoon slot. The day before or on the day, you receive a message before the technician arrives.
Clearing access to the indoor units
The technician works from a stepladder, facing the unit, and fits a collection sheet underneath. So a little space is needed.
- Clear about one metre in front of and below each unit: light furniture, plants, picture frames, fragile objects.
- Move electronic devices sitting directly underneath (television, computer, speaker), even though protection is fitted.
- If the unit is above a bed, remove the duvet or cover it.
- For a ducted unit or a ceiling cassette, locate the access hatch and check that it opens.
There is no need to wash the filters the day before. Their condition helps the technician understand how the unit is used and advise you on the right cleaning frequency.
Arranging access to the outdoor unit
This is often where time is lost. Depending on the location:
- on a balcony or terrace: move furniture and planters away from the unit;
- in a garden or courtyard: plan the way through, and the key to the gate or store if it is locked;
- on a flat roof in a shared building: let the caretaker or managing agent know, and get the key or access approval before the visit;
- on a façade, with no access from your home: say so when booking so that a solution is planned.
Cleaning requires water. An accessible tap (kitchen, bathroom or outdoor tap) and a nearby socket make the job easier.
Electricity, pets, remote control
- The consumer unit must be accessible: the air conditioner is switched off during the work. If the breakers are not labelled, that is fine, the technician will identify them with you.
- Pets are calmer in another room with the door shut: rinsing, vacuuming and coming and going unsettle them.
- The remote control, with working batteries, makes it possible to test the unit in all its modes after cleaning.
Documents and questions to prepare
Gather what you have on the installation: manual, installation invoice, report or log from previous visits. If your installation is subject to leak checks, keep the latest certificate too. Under the EU F-Gas Regulation (EU) 2024/573, this check depends on the refrigerant charge expressed in tonnes of CO2 equivalent: from 5 t CO2e for most equipment, which is about 7.4 kg of R-32 or 2.4 kg of R-410A. Most air conditioners in a flat are below that; some multi-split systems and shop installations can be above it. The charge is shown on the outdoor unit's rating plate.
Also note what you have noticed: an unusual noise, a smell on start-up, dripping water, a code on the display, a room that no longer cools as before. If the unit seems to be struggling, an indoor thermometer and hygrometer left in the room for a few days gives concrete figures to share.

During the visit
On arrival, the technician asks where the units are, listens to your comments, then fits the protection: a sheet under the unit and overshoes for moving around your home. For a simple system of one indoor and one outdoor unit, allow generally one to two hours depending on the unit's condition and ease of access; each additional unit makes the visit longer.
Your presence is useful at the start, to show the way around, and at the end, for the debrief. In between you can get on with your day, including working from home in another room: the vacuum and rinsing make a little noise, nothing more.
If the technician finds a fault beyond routine servicing, it is explained to you. No repair is carried out without your written approval of a quote. The quote is free and sent to you within 48 working hours.
What you are left with afterwards
- A clean home: protection removed, rinse water disposed of, floor checked.
- Clear explanations, without jargon: the unit's condition, what was done, the settings recommended for your use.
- The digital maintenance log for each unit, sent after the visit: date, work carried out, observations and photos. Keep it, it serves as a history, including if you sell or let your home.
- The invoice, with payment on site at no extra cost (cash or bank transfer), or online by card, with 3.5% bank fees passed on at cost.
Then our active vigilance takes over: we get back in touch before the next season and before any leak-check due date.
