If temperatures start to drop in the fall, it might be the best time for homeowners and apartment dwellers to seriously consider installing their air conditioning. Indeed, it is the time to contact a professional in the field for an appointment and an initial discussion about your project. Their schedule is generally less busy than in the middle of summer. But we will see that installation is not the only reason for such a call, including
📋 The essentials at a glance: Personally, I consider calling a certified refrigeration technician a legal and technical necessity as soon as your project involves handling refrigerant fluids. Beyond simple installation, the expert ensures the correct sizing of the unit, thus avoiding excessive electricity consumption and premature compressor wear. I recommend consulting a professional as soon as you notice a drop in efficiency or a suspicious noise, to prevent an expensive total breakdown.
Air Conditioning: Knowing When to Call a Professional for Installation, Repair, Maintenance
🗣️ My experience: In 2024, I saw a neighbor try to install his monosplit himself. To save on commissioning fees, he tightened the fittings poorly, causing a slow leak of R32 gas. In less than two months, his air conditioner no longer produced cold air and the compressor burned out. The lesson is clear: saving 200 euros on a professional intervention turned into a direct loss of 1,200 euros to replace the entire unit. The RGE certification is not just a piece of paper; it is a survival guarantee for your equipment.
Professionals specialized in air conditioning, usually coming from the refrigeration and plumbing fields, are spread throughout the territory. Most often, the challenge is not to find one but to find the right one. Need air conditioning in Paris? The best is to approach a professional ideally located geographically to guarantee the fastest possible service. Whether you are in Paris itself or in the Paris region, calling such an expert will be the most effective for one of the following three standard situations:
- the initial installation of your air conditioning system;

- regular maintenance or servicing as a preventive measure.

🌍 Did you know? A professional does not just look at the surface area of your room. They calculate the “thermal load” taking into account the orientation of the windows, the insulation of the walls, and the number of electrical appliances present. A poor calculation can lead to a 25% increase in your annual electricity bill.
The installation project will precisely determine the features, but also the visual appearance of the whole. Indeed, depending on whether the indoor units are ducted or split systems, the implications will be different. In the case of ducted equipment, casing work, plasterboard, and painting will certainly take place. Splits, which are visible units positioned high up, above doors for example, will not require this.

|---|---|---|---|
| New installation | Planned | RGE Refrigeration Technician | Installation, connection, and commissioning |
| Total breakdown (summer) | High | Air conditioning repair technician | Diagnosis and refrigerant recharge |
| Annual maintenance | Low | Maintenance technician | Cleaning, disinfection, and tests |

Repairs: urgent situations where your technician’s professionalism is tested
When a breakdown occurs on your equipment or its settings, it can become urgent to intervene so that the situation does not persist. This is especially true in summer, when temperatures are such that it is essential to have your air conditioning working. In this case, a repair technician can come on site and carry out the necessary diagnosis. This will determine the defective part(s) causing the breakdown and allow for their replacement. This will be done either immediately or scheduled for a later date depending on the complexity of the breakdown and the availability of parts.
Such a situation could likely have been avoided with planned and regular maintenance.
⚠️ Warning: Beware of “free commissioning” or very cheap offers proposed by non-specialized craftsmen. If the circuit vacuuming is not performed according to the rules of the art with a specific pump, residual moisture will create acids that will corrode the motor from the inside in less than two years.

Maintenance or servicing, the ins and outs are the same. Maintenance consists of carrying out regular checks and cleaning of the various components that make up the system. It also involves certain measurements concerning leaks. By intervening in this way, the professional will be able to detect possible future breakdowns in advance and anticipate the replacement of wear parts in particular.
Usually presented in the form of a maintenance contract, servicing involves a commitment from the professional to come and carry out the necessary checks every year.
💡 Practical tip: If your air conditioning is leaking inside, it is often the condensate tray that is clogged with algae or dust. Before calling the repairman, try gently blowing into the external drain pipe. If this is not enough, a professional intervention with pressure unclogging equipment is necessary to avoid damaging the unit’s electronics.
