At NSG Diagnóstico & Soluciones HVAC, we specialise in offering advanced technical solutions for the maintenance, repair and diagnosis of air conditioning systems. Our mission is to optimise equipment performance and facilitate the work of professionals in the sector with practical, accurate and efficient tools.

With extensive experience in the field of industrial refrigeration and air conditioning, we have developed the EEV CHECKER, a unique device designed for the rapid and reliable diagnosis of electronic expansion valves (EEVs). This equipment, created and tested by technicians for technicians, reflects our commitment to innovation, precision and continuous improvement in the HVAC field.

At NSG, we believe that technical excellence and a passion for engineering are the basis for providing a reliable service. Every project, every device and every field test is part of the same goal: to simplify diagnostics and raise the standards of HVAC maintenance.

We are driven by the idea that technology should be an ally to technicians, not a barrier. That is why we work every day to transform the diagnostic experience into a more intuitive, faster and more reliable process.
