About Us

Our History

Thermaire Investments (Pty) Ltd., was established in South Africa in 1945 under the name Thermaire, as an air-conditioning company supplying air-conditioning to hospital ships for the British Admiralty. The business was later owned by JSE listed construction giant, Murray & Roberts, who changed the name to Improvair.

Since then, the company has been through a number of name and ownership changes and all assets and liabilities were bought from Murray & Roberts in 2005 by private owners. The owners changed the name to Thermaire Investments and introduced various trading divisions namely: Improvair Environmental Solutions (IES), Ductshop, Viking Air Conditioning and Switched-On Solar.

Viking was sold to Swedish company System Air in 2017, marking the start of Thermaire’s restructuring to better position the group as an expert HVAC contractor, while shifting away from the manufacturing side.



In 2018, energy company, ENGIE, acquired 100% of Thermaire Investments’ respective shares. As a global energy company and expert operator in Renewables and Energy Storage, Lighting, Heating and Cooling Systems, and Energy Management and Controls, ENGIE acquired the company in line with its acquisition strategy to grow its presence in the African market.

IES, Ductshop and Switched-On Solar, along with Thermaire subsidiary companies: Improvair Mozambique Limitada, Consorcio Improvair Soclima Limitada and Thermaire FZE in Sharjah United Arab Emirates, today make up the group.


ENGIE acquires Ampair (Pty) Ltd.

ENGIE also acquired 100% shareholding of South African company Ampair (Pty) Ltd., who are specialists in refurbishments, planned preventative maintenance and breakdown and repair of HVAC plants.


Together, Ampair and Thermaire are able to provide turnkey HVAC solutions to customers across the Middle East and Africa, and are expanding their portfolio to provide turnkey Mechanical, Electrical and Plumbing (MEP) solutions for large projects across these regions.
