Getting a commercial HVAC system right starts long before the first unit is bolted down. Our Camden-based design service covers the full specification process: room-by-room heating and cooling load calculations, ductwork and pipework routing, plant selection, ventilation rates to current Building Regulations, and controls strategy. Whether you are fitting out a Camden restaurant, refurbishing an office near Euston, or upgrading plant in a listed building, we produce designs that installers can price and build from with confidence.
Load calculations & system specification
Every design starts with accurate heat gain and heat loss calculations — occupancy, glazing, equipment loads, kitchen extract and solar gain all modelled properly. From there we specify the right system: VRF/VRV heat recovery for multi-zone offices, ducted splits for retail, or comfort cooling paired with mechanical ventilation for hospitality. Oversized plant wastes energy and short-cycles; undersized plant fails on the hottest day of the year. We size it correctly, and document it.
Ductwork design & coordination
Ductwork is where most HVAC projects go wrong. We design supply, return and fresh-air duct runs with correct velocities, attenuation and access for maintenance, coordinated against ceilings, lighting and fire dampers. For Camden’s many older and listed buildings we plan discreet routing and condenser locations that satisfy planners and landlords while still performing.
From design to commissioning
Because we also install and maintain commercial systems, our designs are practical — we specify equipment our engineers know, from Daikin, Mitsubishi Electric, Toshiba, LG and Fujitsu, and we stay involved through installation, commissioning and TM44 compliance. You get one accountable team from first sketch to handover.
