Airflow Engineering

We are Uniquely Airflow

Precision in Every Cut. Perfection in Every Design.

Airflow Engineering (SI) Ltd, known simply as Airflow, is a Christchurch-based family business specialising in HVAC solutions, ducted system design, custom manufacturing, sheet metal fabrication and precision fibre laser cutting.

With over 34 years of industry experience, we work alongside installers, builders, manufacturers, contractors and homeowners, providing practical advice, quality products and reliable solutions backed by genuine industry knowledge.

From ducted heat pump systems, zoning solutions, custom plenums and fresh air ventilation through to precision laser-cut components and custom sheet metal fabrication, we bring design, manufacturing and supply together under one roof.

Our strength is in understanding what our customers need and finding the right solution — whether that means supplying a trusted HVAC component, designing something specifically for the job, or manufacturing a completely custom piece.

Serving residential, commercial, industrial and manufacturing sectors throughout New Zealand, we combine experience and innovation with the values of a family business. We believe in doing things properly, being easy to deal with, standing behind what we deliver and taking pride in the details.

That’s what makes us Uniquely Airflow.

Precision in every cut. Perfection in every design. It’s The Airflow Way.
