What we can offer

Kereen has successfully delivered high quality mechanical projects within the commercial sector.  The majority of these projects have seen the installation and design of energy efficient heating and cooling systems including the use of specialised equipment from heatpumps, air conditioning, to combined heat and power units. 

Having secured a regional agency with Mitsuibishi Electric, Europe’s largest heatpump suppliers, access to their design and after sales team has been paramount in the delivery of specialised craftsmanship with these market leading products. 

Our Team has a proven track record of sharing expert systems experience and knowledge with engineers and architects to assist  at every stage of the build process from consultation and design to installation, commissioning, and maintenance within the semi-commercial areas  for private and government contracts including large residential properties, nursing homes, car showrooms, warehouses, retail outlets, dairy farms, pig farms, and social housing 

We believe in providing our customers with the most energy-efficient system, using the highest quality products resulting in substantial savings and protecting our environment and its inhabitants.
