Integrated technical installation with electrical panel, automation, controlled mechanical ventilation, heat pump and underfloor-heating manifold.
Integrated electrical distribution, automation, ventilation, heat-pump and underfloor-heating system.

Integrated electrical engineering

Energy, climate
and control.
Engineering that connects it all.

We design and install electrical and solar systems, air conditioning, heat pumps, underfloor heating, mechanical ventilation, automation and security for homes, businesses and industrial facilities.

The group

Two companies, two specialities. One point of contact.

AFELTrónica

Electrical engineering · since 1980

  • Electrical installations
  • Solar energy
  • KNX home automation
  • Networks
  • Security & CCTV
  • Automation

When a project brings together electrical, energy and climate systems, both teams work in coordination.

ColdSystem

A company in the same group as AFELTrónica

Climate control, from installation to support.

Supply and installation of thermal comfort and indoor air quality solutions for homes, businesses and industry, with maintenance and technical support after installation.

Solutions for your space

  • Air conditioning

    Heating and cooling for indoor spaces, with temperature control tailored to each zone.

  • Heat pumps

    Solutions for heating and, depending on the system, domestic hot water.

  • Underfloor heating

    Heat distributed evenly through the floor for consistent comfort throughout the room.

  • Controlled mechanical ventilation

    Controlled ventilation brings fresh air indoors to improve indoor air quality.

Maintenance

Equipment care to keep systems working properly and identify when further work is needed.

Technical support

Diagnosis and technical intervention to restore climate control systems to working order.

Energy, comfort & indoor air quality

From sunlight to comfort, everything connected.

AFELTrónica delivers electrical installations, solar energy and home automation. ColdSystem adds its climate control and indoor air quality expertise, with both teams coordinating the integration of the systems.
