Air conditioning in Martigny

Looking for air conditioning in Martigny is most often a reaction to hot summers: the town opens onto the Rhône plain, a dry, sunny valley that is hot in summer. Installing a cooling system in this region takes more than choosing a unit, because the location, the noise and the consents required weigh as much as the technology.

What air conditioning work in Martigny?

Requests revolve around three families of equipment.

• The fixed split air conditioner: an outdoor unit connected to one or more indoor units. It is the most common solution for cooling a bedroom, a living room or an office.
• The reversible heat pump: it heats in winter and cools in summer. It is mainly of interest to those who are already renovating their heating.
• Cooling integrated into an existing system, when the installation in place allows it.

Martigny is a crossroads: the town lies at the bend of the Rhône, on the road to the Great St Bernard and Chamonix. The buildings here are varied. Flats in town-centre apartment blocks, villas on the slopes and commercial premises do not raise the same questions. In a flat, the issue is often finding where to fix the outdoor unit without bothering anyone. In a villa, the problem is rather choosing between one unit per room and a distributed system.

What the plain and the slopes change for your installation

The climate of central Valais plays a direct role. In the Rhône plain, summer heat builds up in homes that are poorly protected from the sun. A poorly insulated roof, large south-facing windows or an exposed top floor are enough to make nights difficult.

Before talking about a unit, it is worth looking at where the heat comes from:

• glazing exposed to the sun, which can be dealt with using external blinds or shutters;
• attics and roofs, whose insulation matters as much in summer as in winter;
• night ventilation, free when the air cools down;
• internal gains: kitchen, electronics, lighting.

Solar protection does not always replace air conditioning, but it reduces the capacity needed, and therefore the size of the unit and its consumption. A good installer will raise this option without being asked.

Between the plain and the slopes, installation conditions differ. On the plain, buildings are often close together and the outdoor unit may end up near a neighbouring window. On the slopes, steep plots sometimes complicate the routing of the lines and access for maintenance. In both cases, ask for a site visit: a remote estimate sees neither the façade nor the neighbours.

Heritage and built environment: check before drilling into a façade

Martigny is home to a Roman amphitheatre and the Pierre Gianadda Foundation, two landmarks that remind us the town has a heritage to preserve. That does not mean your street is affected. But if your building is in a sensitive area or has a protected feature, an outdoor unit visible from the street may run into requirements on appearance.

The useful reflex: ask the municipality whether your building is subject to particular protection or a façade rule. An installer can suggest a discreet location (courtyard, flat roof, side not visible), but it is for the municipality to say what is acceptable.

Permits, noise and consent: the procedures in Martigny

Three questions come up almost every time.

The building permit and energy law

In Switzerland, installing air conditioning may require a permit or a justification depending on the canton, under its energy law. In Valais, the building permit is issued by the municipality in the building zone, and by a cantonal commission outside the building zone. On the energy side, the cantonal energy and hydropower department is the contact, and a cantonal subsidy programme exists. These rules change: confirm what applies to your project with the municipality of Martigny and the cantonal department, without assuming any aid.

If your house is a chalet or a second home, federal legislation on second homes may affect certain municipalities. Again, check the status of your property with the municipality.

Outdoor unit noise

The outdoor unit must comply with the values set by the Noise Abatement Ordinance (OPB). In practice, the location is decisive: distance from neighbouring windows, no reverberation against a nearby wall, a support that does not transmit vibrations. Ask for the quote to state clearly where the unit will be placed.

The landlord and the co-ownership

In an apartment building, the consent of the co-ownership or the landlord is required. A tenant cannot drill into a façade or fix a unit to a balcony without the landlord’s written permission. In condominium ownership, the façade and roof are generally common areas: the meeting of co-owners must decide. Allow time for this discussion before setting a date for the work.

Preparing your request and comparing quotes in Martigny

The more precise your description, the more comparable the quotes will be. Note:

• the type of property (flat, villa, premises) and the floor;
• the rooms to be cooled and their exposure;
• the intended use: cooling only, or heating as well;
• the planned location for the outdoor unit;
• your occupancy status: owner, tenant, co-ownership;
• the solar protection already in place.

A good quote details each item separately: units, installation, refrigerant lines, condensate drainage, electrical connection, commissioning, maintenance. It also specifies the make and model, as well as what is planned to limit noise.

The cost varies with the number of units, the capacity, the difficulty of access, the length of the lines, the masonry or electrical work required and the procedures to be planned. There is no price valid for everyone: only a quote drawn up after a visit reflects your situation. Compare proposals item by item rather than on the total.
