Airflow Engineering (SI) Ltd, known simply as ‘Airflow’, is a Christchurch based independent supplier of Heating, Ventilation and Air Movement products.

Airflow Engineering (SI) Ltd started its life as “Derek Thompson HEVAC Sales” in 1988, and grew into Airflow Engineering (SI) Ltd in 1992. 1st May 1994 Derek lost his fight to cancer, a huge blow to the family and business.  Intrepidly taking over Airflow at this time Cherry (Derek's daughter) has owned, operated and established Airflow in the market place.

Airflow has always continued to expand with a wider range of product and services. 2000 saw the company adopt the brand name of ‘AIRFLO’, to highlight its move into a “one-stop” Heating and Ventilation wholesaler, and to brand a range of its own designs. 2001 Airflow invested in a interlock flexible duct-manufacturing machine, proving to be a solid investment. 2001 again saw growth, with expansion into larger and higher profile premises in Carlyle Street, Sydenham. 2005 Airflow continued to grow with new and improved product lines, along with machinery to manufacture Airflo Grease Filters & Airflo Electric Duct Heaters. 2006 Airflow were appointed agents for the Carrier Allied Product range and Woods Fan stockists. 2007 Airflow was appointed SI distributor for Aircon Flange. 2009 we started working with and promoting  Xpelair and Alsynite products, again products where brand name speaks for itself.

2008 saw the start of the 3rd generation to Airflow, Alex, Derek’s eldest grandson, Kevin & Cherry’s son, joins the company as a junior. Airflow employs 6 staff, it is still family owned and operated, and its values reflect just that.
