What we do
Air Conditioning Installers and Controlled Environment Specialists in the UK
TEK carry out the installation of air conditioning, air source heat pumps, and climate control systems to all buildings and offices. We also specialise in the design and build of bespoke systems for specific professional industries, such as close control rooms, cmm rooms and cleanrooms.
We are based in Bristol, but cover the whole of the United Kingdom. We also operate internationally, providing our specialist services to a range of high-profile clients all over the world including Europe, Singapore and Scandinavia. These clients benefit from our experience in creating systems, or whole rooms, that have very tight atmospheric parameters.
TEK can assist you at any stage, from the initial design process through to installation and aftercare. Our AC maintenance packages are not exclusively offered for systems that we installed ourselves – we can provide structured maintenance programmes or one-off servicing to any system, regardless of brand and installer.
As an MCS certified installer, working with TEK to install air source heat pumps may allow you to qualify for government grants through the Boiler Upgrade Scheme.
Our services are carried out exclusively by our in-house engineers, who all hold CSCS Skill Cards and have F-Gas certification. We are registered with SafeContractor, BESA, REFCOM Elite and FSB. We are also approved Daikin D1+ installers, which enables us to offer a 7 year warranty on Daikin products which is exclusive only to approved installers. We can also offer other manufacturers such as Mitsubishi, Toshiba, LG and Samsung.
