Craig installed our air con unit recently and what a fantastic service!! He was respectful, polite and friendly. We were kept up to date regularly before the fitting and nothing was too much trouble. Craig didn’t stop from arriving to leaving (not even for a brew). The unit is almost silent, not at all imposing and looks very modern and stylish. Would highly recommend!! A*****

From Our Website

The Sub Zero team are happy to undertake many different commercial projects of varying size and application. We are happy to design systems from plans provided by customers or one of our surveying team will happily arrange to visit your site and walk you through the many options available. Commercial projects may vary from a simple split system in a small office to a more complex VRF system spread over 3 or 4 floors of a building, whatever the requirement Sub Zero will help and guide you through the process.


Something as simple as a blocked filter or blocked condensor coil can reduce your systems efficiency by upto 60%. Restricted airflow can cause serious mechanical failure costing hundreds of pounds in repairs or often leads to water damage to interior decoration or equipment. The Kyoto Protocol 1997 is an international treaty which is committed to reductions in emissions that contribute towards global warming or climate change. HFC (Hydroflourocarbon) refrigerants are one of the 6 greenhouse gases that the Kyoto protocol applies to and we must take steps to ensure emissions are kept to a minimum.


Sub Zero offer design and installation packages to meet any bespoke requirement from a simple single unit providing comfort cooling through to sophisticated, complex heat recovery VRF projects. All of our systems are designed with environmental factors in mind, we only install the latest energy-efficient equipment using the latest environmentally friendly refrigerants in line with the latest F-Gas regulations. In an ever-changing industry the Sub Zero team remains focussed and committed to ensuring our customers meet industry regulations at all times.
