About Us

With over 40 years of experience in the industry, RSI provides unparalleled service when it comes to design and installation of air conditioning systems in London and the South East.

RSI have extensive experience working in all industry sectors including healthcare, data centers, retail outlets, commercial offices, hotels, banks, schools, museums and government buildings.

As members of the Mitsubishi Business Solution Partner and Daikin D1 schemes we can offer 7 years parts and labour warranty on all of their equipment. We are also happy to provide quotations for Sanyo, Fujitsu, Toshiba and all other mainstream air conditioning manufactures.

We can help you decide the type of equipment that best suits your needs from small splits systems to large VRF systems for multiple rooms or open plan office areas. 

The majority of air conditioning systems will also supply heating during the winter months. These 'heat pump' systems provide one of the most efficient methods available for heating a building.
