Air conditioning & HVAC services

Installation & design

Design and build, from a single split to a full VRV retrofit across a live building.

We take a system from conception to completion — heat load calculations, in-house CAD design, installation, commissioning and the handover pack. VRV and VRF, fan coils, splits and multi-splits, AHUs, MVHR, ductwork, chilled beams and the pipework and containment that ties it together.

• VRV / VRF design and installation
• Fan coil and cassette systems
• Splits and multi-splits
• AHUs, MVHR and ventilation
• Ductwork, pipework and containment
• In-house CAD and heat load design

Maintenance & repair

Dedicated service and breakdown engineers, minimising down time.

Our aftersales support provides tailored maintenance packages to ensure continued optimum performance and efficiency from our installations. We also take on other people’s systems — in-depth investigational and repair works are our forte, from a failed inverter compressor to a burning smell in an AHU nobody can trace.

• Planned preventative maintenance
• Breakdown and callout cover
• Fault diagnosis and investigational works
• Compressor, PCB and heat exchanger replacement
• System cleaning and validation
• F-Gas compliance documentation

Heat pumps & net zero

Innovative solutions for Net Zero compliance, and the advisory work that gets you there.

Air and ground source heat pumps, heat recovery ventilation, and the energy reduction and decarbonisation advice around them. We have installed full mechanical packages — heat pump, underfloor heating, ventilation and plumbing — on low-carbon homes that went on to achieve a BREEAM Excellent rating.

• Air source heat pumps (ASHP)
• Ground source heat pumps
• Heat recovery ventilation (MVHR)
• Energy reduction and decarbonisation advice
• Replacing redundant chillers with heat pumps
• R22 and legacy refrigerant replacement

Controls, BMS & air quality

Systems that report on themselves, and ventilation that responds to the room.

Integration onto building management systems to aid with minimising energy usage, third-party run and fault monitoring, and centralised controller programming. CO₂ controlled systems influenced by occupancy level keep indoor air quality at an optimum without ventilating an empty floor.

• BMS and BEMS integration
• BACnet and centralised controllers
• Run and fault monitoring
• CO₂ controlled ventilation
• Indoor air quality monitoring
• Thermal imaging surveys

Ventilation & kitchen extract

Extract, supply and the awkward bits in between.

Commercial kitchen extract hoods, ducting, attenuators and fan motors; switch-room and server-room extract complete with fire dampers and power supplies; and ductwork adapted around the things a building throws at you — including a manhole a developer had concreted over and hidden behind the supply air duct.

• Commercial kitchen extract systems
• Attenuators and fire dampers
• Switch room and server room extract
• Supply and extract ductwork
• Air transfer systems
• Testing and commissioning

Strip-out & decommissioning

Getting equipment out safely, and to regulation.

Decommissioning and removal ahead of refurbishment or demolition, with systems recovered, pressure leak tested and re-commissioned to F-Gas regulation where they are going back in. We have stripped out 19 split systems for the demolition of a temporary HS2 office and re-piped 14 live VRV systems so a roof could be replaced over them.

• Decommissioning and safe removal
• Refrigerant recovery to F-Gas regulation
• Re-pipe and relocation works
• Strip-out for refurbishment or demolition
• Pressure and leak testing
• Re-commissioning and handover
