nch office was officially set up on 15th October 2012 Lead by Mr.Willie Sim (Assistant General Manager) until today. Mr.Willie Sim is regarded as one of Sabah’s most capable and dependable VRF specialists, known for combining strong engineering discipline with practical field experience. His work spans government facilities, consultant-led designs, commercial developments, and contractor-driven installations — making him a central technical figure in the state’s VRF market. Recognized for his accuracy in VRF system logic, Mr.Willie is often called upon to validate design assumptions, clarify technical disputes, and support decision-making where performance and reliability are critical. Consultants and JKR officers rely on his ability to explain real operating behaviour — compressor modulation, part-load efficiency, refrigerant balancing, piping constraints, controller configuration, safety requirements, and system protect logic — in a clear and grounded manner. Contractors value him for a different reason: he is hands-on, responsive, and willing to be on-site when issues arise. His approach is straightforward and disciplined — identify the root cause, verify it with measurements, and resolve it with engineering-based solutions. Contractors often describe him as “reliable under pressure” and “able to give exact answers, not general statements.”

Across project stages — from design verification to testing, commissioning, and rectification — Mr.Willie’s consistency sets him apart. He is known for standing by his technical assessments and supporting teams until the system performs as intended. This reliability has positioned him as a preferred technical contact for teams looking to reduce risk and increase confidence in VRF deployment. Today, Mr.Willie’s reputation across Sabah is defined by:

High technical accuracy backed by field validation

Strong credibility with consultants and JKR due to clear, non-sales-driven communication

Strong support for contractors with practical troubleshooting and on-site presence

Reliable assistance during tenders, design reviews, and commissioning

Proven ability to handle complex VRF project demands across government and commercial sectors

With a steady, disciplined working style and a commitment to engineering integrity, Mr.Willie continues to strengthen his standing as a trusted VRF authority in Sabah — someone consultants, JKR, and contractors rely on when system performance truly matters.
