Kins Engineering Limited is a Hong Kong–based professional supplier and service provider specializing in mechanical and electrical engineering, air-conditioning systems, and fresh air units. We focus on delivering high-quality air-conditioning installation, maintenance, and fresh air system solutions for residences, offices, retail shops, and schools.
Founded in 1983, we understand the growing concern among Hong Kong residents regarding indoor air quality and energy efficiency. Sealed living and working environments, prolonged use of air-conditioning, PM2.5, pollen, odors, formaldehyde, and carbon dioxide buildup—all of these issues quietly affect family health and the city’s sustainable development.
Therefore, beyond traditional professional installation and regular maintenance of air-conditioning systems, we have also independently developed and manufactured our own brand of fresh air unit. Leveraging our extensive engineering experience and applied science, we are committed to bringing fresh air into every Hong Kong home and commercial space.
Who We Are
Danny Ip
Chief Executive Officer (CEO)
For over 40 years, Danny has been a driving force in revolutionizing air technology. Every system he designs is built from firsthand experience, tested, refined, and reimagined in real-world conditions.
His creation, the Fresh Air Unit (FAU), is based on real-world challenges he encountered in workshops and job sites. While most business owners stay behind desks, Danny thrives on the frontlines, personally engaging with machinery. He breaks conventional rules, and rebuilds them with his own designs, creating a smarter and more adaptable way to manage indoor air.
