Why is it important to distinguish between replacement, relocation, and new installation?
When an old unit stops working or a decision is made to replace it, the technical scope varies depending on what happens with the outdoor unit and the routing of the refrigerant, electrical, and drainage lines. In the information of the municipal communication sheet for construction works of the Alcalá de Henares City Council the assumption of replacement or renewal of indoor air conditioning installations is considered as long as the authorized technical conditions are maintained, specifying express limits regarding the facade, the structure, the distribution, the common elements, and the protected buildings.
From that informational guideline, it should not be inferred that any new installation or any relocation of the outdoor unit is exempt from procedures. Each property and each project have specific construction and urban planning characteristics that must be confirmed before carrying out the work.
| Action scenario | What changes in the home or premises? | What should be checked before hiring? |
|---|---|---|
| Replacement while maintaining conditions | The units are replaced in the same location, utilizing existing compatible connections and layouts without altering the façade, structure, or common elements. | Confirm that the pipes, drainage, and supply can accommodate the new model and check in the municipal information if the action fits within the interior replacement limits. |
| Change of position of the outdoor unit or new routing | The outdoor unit is relocated to another point (balcony, patio, roof, or facade) or new wall openings and conduits are created. | Define the exact layout and consult beforehand with the Town Hall and, if it affects shared walls or areas, with the homeowners' association. |
| First installation without pre-installation | The location of the indoor and outdoor units, the drainage of condensates, and the electrical connection are designed from scratch. | Agree on a layout of the location and steps before acquiring the equipment to consult its urban and community feasibility. |
| Property in Historic Center or Monument Surroundings | Any intervention in buildings located within the protected area or in the vicinity of a listed property. | Refer the specific inquiry to the municipal Historical Heritage department before installing supports, ducts, or outdoor units. |
In addition to the location, check the criteria for utilizing existing refrigerant pipes before selecting the equipment and finalizing the installation.
Where to direct the municipal inquiry based on the location of the property?
The same inquiry does not apply to all buildings in Alcalá de Henares. Not all facades and buildings in the municipality are subject to historical protection regulations, nor do all replacements receive the same administrative treatment.
According to the section of Processing of Works (OCU Works) and the Urban Planning Office of Alcalá de HenaresConsultations regarding actions on properties located in the Historic Center or in Monument Surroundings are referred to the Historical Heritage Discipline and Licensing service. In contrast, for homes or premises situated outside of those protected areas, guidance on the applicable procedure corresponds to the general Urban Planning channels.
Since the informational sheets on the web include regulatory references from different dates, it is wise not to assume any permission by analogy and to always consult the exact address of the property and the description of the planned installation.
How to describe your installation before consulting the Town Hall, the community, or the installer.
To ensure the consultation refers to your installation, describe how and where you want to place the device. Gathering some basic data in advance facilitates both the administrative consultation and the preparation of an accurate technical budget:
- Current and planned location of the units: Note in which room each indoor split works and where exactly the outdoor unit is supported or hung (terrace floor, support on interior wall, patio, or roof). Indicate if you intend to use the same opening or move it.
- Connection and drainage layout: observe where the ducts run today or if there is built-in pre-installation, where the condensate pipe drains and from which point the system draws power.
- General and non-invasive photographs: Take pictures from a safe position, without disassembling covers or leaning into facade openings. It is useful to photograph the specification label of the current machine, the location where the outdoor unit is installed, and the visible path of the pipes.
- Known conditions and pending questions: separate what you already know (for example, internal rules provided by the property manager regarding schedules or balcony aesthetics) from what you need to confirm during the technical visit (such as the diameter of the existing pipes or the appropriate cooling capacity).
Always distinguish between these. practical preparation notes and the official documentation that the City Council can require when appropriate to initiate a file.
From the preparation of the assembly to the selection of the equipment
Having a clear understanding of whether the project involves a direct replacement of existing connections or a new installation with a different layout helps to identify which tasks should be included in the budget. It also aids in making an economic comparison to determine whether it is worth repairing a fault in the current unit or completely replacing it.

Frequently Asked Questions
No. It is used to describe your case and prepare the consultation. The official documentation and the applicable procedure must be confirmed with the corresponding municipal department; this list is not a form nor does it grant authorization.
You can compare models, but the choice must be contrasted with the planned location and layout. Before purchasing, clarify what is retained, what is modified, and what conditions of the property remain to be confirmed.
No. Only collect what you can observe from a safe position and through the usual access points. Do not remove casings, do not manipulate connections, and do not lean out over the facade. If a label or the exterior is not accessible, indicate this when requesting the inspection.
