As a ventilation contractor accredited by the Hong Kong Government and a specialist contractor registered with the Buildings Department, we carry out all projects in strict compliance with the Hong Kong Buildings (Ventilation Systems) Ordinance.
Upon completion, an air conditioning system certificate, a Fire Services Department F.S.251 certificate, and a Class II compliance certificate will be issued in accordance with the law, ensuring the work is performed by licensed professionals.
With over 30 years of experience in Hong Kong’s air conditioning and ventilation industry, we have completed more than 1,000 projects and served over 1,000 clients.
We have earned the long-term trust and recognition of leading educational and medical institutions across Hong Kong, as well as renowned business groups, including The Chinese University of Hong Kong, Tung Wah Group of Hospitals, MTR Corporation, and Prince of Wales Hospital.
With robust technical expertise, we not only undertake the installation of high-capacity central air conditioning (chiller) systems and ductwork for large commercial buildings, but also specialize in high-specification engineering projects for specialized environments requiring precise temperature control (such as the design and installation of the P3 laboratory at the Chinese University of Hong Kong, temperature-controlled cold storage facilities, and cleanrooms in the Ho Sin-hang Engineering Building), with technical capabilities that are unmatched in the industry.
We provide a full range of services, from initial site surveys and design, drafting and code compliance, and permit filing and installation, to ongoing annual maintenance and deep-cleaning services—including the removal of cage-type fans and motors, as well as high-pressure cleaning with chemical solutions. We offer year-round technical support to our commercial contract clients, relieving them of the burden of complex project management.
Schools, museums, and government agencies in Hong Kong have the strictest requirements for fire safety and engineering compliance. The fact that we have been awarded dozens of major projects at The Chinese University of Hong Kong in succession is the best testament to our capabilities.
Commercial projects demand efficiency, energy conservation, and rapid response. We possess cutting-edge expertise in installing high-capacity central air conditioning (chillers) and medical-grade ventilation systems, helping restaurants and other businesses expedite the licensing process.
This demonstrates the long-standing trust the company has earned in the maintenance of high-end residential complexes, condensation prevention and cooling projects, and the day-to-day mechanical and electrical operations and maintenance of large-scale properties.
