About
H2O Power Jetting Services
Our company was established on 21 April 2016, built on a strong foundation of experience, skill, and dedication. After many years working in the high-voltage electrical industry and gaining extensive knowledge in air conditioning installation, maintenance, and general works, we decided it was time to create something of our own. That’s how this family business began — founded by Leon Owies, whose passion for quality workmanship and reliable service has guided the company since day one.
A few years later, Leon’s daughter joined him as a 50% shareholder, helping to expand the company with fresh ideas and a shared commitment to excellence. Together, they continue to uphold the values that the business was built on — honesty, professionalism, and a hands-on approach to every project.
From electrical and air conditioning services to general maintenance and repairs, our goal is to provide dependable solutions that meet our clients’ needs and exceed their expectations. As a proud family-run business, we believe in building lasting relationships through quality work and personal service.
