About Us

What makes us different

Ranko has a strong commitment to making things right the very first time. Slipshod work leads to the need for maintenance, and therefore further costs to the customer. We believe in the ethics of proper work, and we hold ourselves to our standard instead of comparing it to the industry.

Ranko is involved in a range of installations including electrical and mechanical installations, air-conditioning and ventilation,mechanical and electrical engineering, plumbing and piping, fibre optics, as well as security and surveillance systems.
