About Us

HVCA Air conditioning Member Logo



AlterTherm has been a specialist provider for over 35 years and has achieved an outstanding reputation for our experience and the quality of our projects.  Our enviable client base is testament to our being a market leader for the supply and installation of air-conditioning and ancillary works

Renowned for both the particularly large and the exceptionally difficult projects AlterTherm has proved itself as a market leader in every aspect.  With a carefully managed framework of in-house engineers no job is too large or too small

AlterTherm offers an all inclusive service from design & planning of the installation through to service & maintenance & all aspects of after sales and service 

Having completed tens of thousands of Hotel Bedrooms for example, AlterTherm is exceptionally experienced in working to tight schedules within 'live' buildings and many Blue Chip clients have and do rely on AlterTherm to minimise off-line rooms or other premises which usually means a vast cost saving to the client

Holding all the required credentials, and more, AlterTherm has a strong commitment to Health & Safety; Environmental Protection; Employee Welfare & Advancement; and Anti-Discrimination.  This is further demonstrated by the Client partnership programs we are part of e.g. 'The Planet 21' program
