Our Process
A proven 4-step methodology that guarantees every HVAC system we deliver performs to specification from day one.
Site Assessment
Our engineers conduct a thorough on-site survey — measuring spaces, assessing heat loads, reviewing existing infrastructure, and identifying the optimal HVAC solution for your building.
Engineering Design
We produce detailed 2D and 3D design drawings, airflow calculations, equipment schedules, and energy efficiency reports — all fully compliant with Kenyan building codes.
Fabrication & Supply
Ductwork is fabricated in-house at our Nairobi workshop. Equipment is sourced from leading global brands and delivered ready for installation on your project schedule.
Installation & Commissioning
Our certified installation teams work to strict timelines. On completion, every system is fully commissioned, tested, and handed over with as-built drawings and user training.
