While technology permeates every aspect of work, skilled technical and manual trades are experiencing a boom. Electricians, industrial maintenance specialists, refrigeration and air conditioning technicians, welders, mechanics, and photovoltaic installers are not only weathering the wave of automation; they are gaining value. The reason? The combination of practical skills, professional judgment, and on-site presence makes their work very difficult to replace with AI.

We're not talking about repetitive tasks, but rather professionals capable of diagnosing, installing, and maintaining physical systems in real-world contexts. As Xavier Alandes, director of Tecnio (the first Center for Advanced Technical Training), often explains, complete automation is still a long way off because these jobs involve situational decision-making, with safety requirements and adaptation to each environment. AI already helps with planning, documentation, and monitoring, but technical responsibility and execution still rest with experts.

Why technical professions are growing in the face of AI

Artificial intelligence and digitization bring efficiency to documentation, calculation, and control, but the differentiating value of traditional trades remains where a professional is needed in person: installations, commissioning, complex diagnostics, and work involving regulations and safety. It is in these areas that demand and remuneration are increasing.

• On-site intervention: Electrical, hydraulic or thermal assemblies are carried out in homes, businesses and factories with changing conditions, so the adaptation on the ground it's key.
• Diagnosis and safety: interpreting noises, vibrations, voltage drops, leaks or load losses requires technical judgment, adequate measurements and strict compliance with regulations.
• System integration: With the energy transition, aerothermal energy, photovoltaics and home automation require teams to be coordinated and verify its efficiency on the whole.
• Local value chain: These are proximity services that they do not relocate easily and sustain the productive fabric of neighborhoods and industrial estates.

AI adds planning capabilities, but responsible and safe execution remains in the hands of specialists. This translates into a market with significant opportunities for those who are well-trained, have a practical approach, and are directly oriented toward employment.

The professions that will be strengthened by AI

When we talk about "manual labor," it's important to clarify: these are jobs with a high technical component and a real impact on energy efficiency, safety, and sustainability. In some cases, such as skilled plumbing, for urgent or highly specialized services, rates can reach close to €200/hour , while in other professions more exposed to digital tasks, some functions could indeed be automated by AI.

• Low voltage electrician: installation of lines and mechanisms, assembly of panels, home automation integration, preventive and corrective maintenance, with a focus on REBT and quality of supply.
• Industrial maintenance (mechanical and electromechanical): production lines, power transmission, lubrication, alignments and strategies TPM to reduce stops.
• Industrial refrigeration and air conditioning: cold rooms, air conditioners, aerothermal energy, fluorinated gas management and energy optimization with measurement and balancing.
• Welding: MIG/MAG, TIG and arc processes applied to boilermaking, structures and piping, with control of deformations and cord quality.
• Mechanics: maintenance of machinery and industrial vehicles, diagnosis with instrumentation and repair procedures.
• Installation of solar panels: Basic sizing, assembly, wiring, regulations and safety in working at height, with special attention to the commissioning and monitoring.

All these profiles share something in common: they require practical skills , the ability to read technical documentation, use measuring tools, and the capacity to work with standards and procedures. Demand is steady and rising due to the energy transition and industrial modernization.

How long does it take to be working?

Effective training programs combine workshops, regulations, and real-world practice : content from the REBT (Low Voltage Electrotechnical Regulations), RITE (Regulations for Thermal Installations in Buildings), machine safety, occupational risk prevention, and company internships. The idea is to learn by doing from day one to consolidate skills in assembly, maintenance, and troubleshooting.

A very common approach is to start with an intensive course and then add qualifications or professional certifications in the chosen field (electricity, air conditioning, refrigeration, industrial maintenance, welding, or photovoltaics). With an applied approach and instructor guidance, the transition to employment can happen in 4–5 months , especially if training is provided in reading schematics, using instrumentation, and preparing technical documentation.

The key is exposure to real-world installation and maintenance environments , working with blueprints, troubleshooting, and mastering commissioning procedures. This way, students gain confidence and shorten their time to entering the workforce.

Where to train: specialized centers, approvals, and certifications

There are centers that have redesigned technical training to accelerate employability. One of them is Tecnio , conceived as Spain's first Advanced Technical Training Center, with the mission of connecting talent with real jobs in energy, industry, construction, and renewables. Its approach is practical, personalized, and flexible, closely aligned with the needs of companies.

Their offerings include training in electricity, maintenance, air conditioning, and renewable energy , with programs developed by active professionals and direct collaboration with leading brands. They have state-of-the-art technical rooms and workshops—with approximately 700 m² of space in Madrid —a job placement service, and agreements with companies such as Vaillant, Saunier Duval, ABB, Simon, and Daikin to facilitate job placement.

Tecnio is also officially accredited by the Community of Madrid to offer Vocational Training for Employment (center code 28588 ). They prepare students for in-demand certifications such as the Electrician's License (REBT) , the RITE certification , and the Photovoltaic Installer qualification , along with specialized courses in industrial refrigeration and air conditioning. This allows students to complete their training with the accreditations required by regulations and access better-paying jobs.

An important aspect is the support provided: individualized follow-up, assessment of practical skills , and workshops where participants work with real instruments and materials. This methodology reduces the gap between the classroom and the workplace and accelerates employability.

Other avenues and job offers beyond industry

In addition to the electrical, thermal, and industrial sectors, there is a wide range of trades available to start, strengthen, or update skills in local areas. Depending on the training offered by different schools, you can find courses in cashiering, butchery, organic farming, warehousing, solar panel installation , and freight handling , among others.

These programs address real needs in commerce, logistics, and services, enabling students to advance their careers with practical training. The idea is clear: to train for a stable profession with promising future prospects, connecting student motivation with market demand.

For those seeking options related to logistics or gardening , there are also short modules to update skills and quickly re-enter the workforce. The key is to identify where the local demand is and choose programs with internships or job placement services.

Privacy, commercial communications, and data transfer: what you need to know

Many schools include sections on data protection and consent in their forms. For example, entities in the sector such as INENKA Formación de Postgrado, SL —with tax identification number B25842592 and registered office at C/ Domènech Cardenal 2, office 1º4º, 25230 Mollerussa— state that the data provided is used to send commercial communications related to their offerings and other communications that may be of interest.

The legal basis is usually the data subject's consent , and it is noted that the individual can exercise their ARSOPL rights (access, rectification, erasure, objection, portability, and restriction of processing) by providing sufficient identification and writing to the center's contact email address (in the case mentioned, [email protected] ). Furthermore, the option to accept or decline receiving marketing information from other companies within the same group is typically offered.

Another common option allows you to authorize sharing your email address with external partners to generate advertising audiences, clarifying that this doesn't mean receiving more emails, but rather improving segmentation. Before checking anything, it's advisable to read the Privacy Policy and make sure you understand what each option entails.

Cookies and user control on the web

Users can usually accept or reject the use of cookies via visible buttons—for example, "Accept" and "Reject"—as well as configure their preferences. Choosing one option or the other should not prevent access to essential information, although it may affect certain functionalities or content personalization.

Market trend and seasonality of demand

The need for skilled tradespeople remains constant throughout the year, but there are seasonal peaks. In air conditioning and refrigeration, for example, this is noticeable with the arrival of heat or intense cold; in photovoltaics, it's seen during subsidy periods or surges in self-consumption. Some publications highlight this reality with articles like "Looking for a job this season?" and specific time markers (such as a date and time like 09/26/2025 11:23 ) to guide candidates on when to start their search.

To take advantage of this dynamic, it's advisable to plan your training to finish just before peak demand. This way, your internship or first professional experience will coincide with the time when hiring is highest and it's easier to secure a contract.

How to choose your training itinerary well

Before enrolling, consider three aspects: the workshop and practical hours , the real-world connections with companies (job placement services and partnerships), and the official certifications it prepares you for. Ask to see the facilities, inquire about the equipment and materials used, and request examples of technical documentation used in class.

Another key criterion is the teaching staff: active instructors who provide real-world case studies , typical mistakes, and diagnostic procedures make all the difference. And in terms of duration, intensive programs focused on professional competence are better than highly theoretical modules without sufficient practical application.

Tips to speed up job placement

While you study, build a solid foundation in reading schematics , using a multimeter, clamp meter, and other measuring tools. Document your practical experience with photos and technical notes; these will help you in your interviews.

If the center offers job placement or internships, prioritize companies where you can experience a variety of situations: system start-ups, preventive and corrective maintenance, and emergency services. This exposure accelerates your learning curve and builds operational confidence.

Finally, maintain an impeccable attitude of safety and compliance : PPE, lockout/tagout, pre-checks, and signed reports. A reputation as a reliable and methodical technician is often what guarantees you continued work.

Authorizations and regulations that open doors

Among the most valued accreditations are the REBT (for electrical installers), the RITE (for thermal installations), and the photovoltaic certification . These certifications demonstrate your mastery of the regulations, installation procedures, and required safety conditions.

Completing your profile with training in industrial refrigeration and air conditioning makes you more versatile: from balancing and charging to the management of fluorinated gases, always with a focus on energy efficiency and compliance with environmental regulations.

Professional opportunities and conditions

Career opportunities include electrical installations, air conditioning and refrigeration companies, industrial line maintenance , metallurgy and structures (welding), maintenance services for residential communities, and solar energy companies . With experience and specialization, technicians often move into team leader roles , maintenance managers, or start their own businesses.

Regarding working conditions, in addition to the sector's base salary, on-call shifts and emergency work typically result in higher pay. For example, in urgent or specialized plumbing or electrical jobs, many qualified professionals earn high hourly rates , and the market rewards availability and quality of service.
