Improvair Environmental Solutions Pty Ltd

Operating since 1945, Improvair Environmental Solutions (IES) is one of the oldest air conditioning companies in South Africa and part of the Thermaire Investments group, which is fully owned by the French company ENGIE. The company was started in 1945 by Mr. Robert J. S. Caldwell, who began by providing air conditioning for hospital ships for the British Admiralty in Port Elizabeth harbour. Since then, the company has been through a number of name and ownership changes; all assets and liabilities were bought from Murray & Roberts in 2005, and in 2018 ENGIE bought 100% of the shares of the Thermaire Investments Group, which included IES. We have over 70 years of experience within the HVAC industry and work on medium to large scale projects ranging between R 5 million and R 500 million in value. Our 250 staff members across our branches in Johannesburg, Western Cape, KwaZulu-Natal, Mozambique and the UAE enable us to service South Africa and Sub-Saharan Africa, while our in-house manufacturing facilities allow us to manufacture key HVAC components at competitive prices and shorter lead times.
