Roman Dihtiarov is a certified appliance and refrigeration technician with more than 12 years of professional, hands-on experience across residential, commercial, and light-industrial equipment. Known for engineering-level diagnostics, advanced system restoration, and precision technical work, Roman has built a reputation as a specialist capable of solving complex cases other service providers decline.

With a formal degree in engineering, Roman combines deep theoretical knowledge with extensive field experience. This dual background enables him to go beyond standard part replacement and instead redesign, adapt, and restore systems using real engineering calculations and advanced diagnostic methodology.

Advanced Technical Expertise

Roman specializes in high-level diagnostics and precision restoration, including:

• Sealed-system engineering: redesign, leak elimination, custom line adaptation, and system optimization
• Factory-authorized compressor replacements (designated subcontractor for LG)
• Component-level electronic repair:
• control board diagnostics
• failure-mode analysis
• micro-soldering and circuit restoration
• Custom part engineering:
• designing 3D CAD models
• preparing precise technical prototypes
• producing unique components on high-performance 3D printers
• Commercial refrigeration and food-service equipment repair
• In-warranty service partner for Dukers
• Precision calibration, electrical safety compliance, and long-term reliability improvements

Roman is one of the few specialists in the region capable of restoring failed systems at the engineering and component level, rather than simply replacing parts. His work significantly reduces repair costs, extends equipment life, and minimizes electronic waste.

International Engineering Background

Roman previously worked under a formal technical contract with Helion AG, one of Switzerland’s leading solar-energy companies. His responsibilities included the installation and servicing of high-voltage solar systems up to 1500V, strict electrical-safety compliance, and precision installation in accordance with Swiss and EU technical standards.

This experience strengthened his expertise in electrical engineering, advanced diagnostics, high-accuracy measurements, and safe operation in high-risk environments.
