01 — Air Conditioning
Air Conditioning
From a single split unit to a multi-storey VRF/VRV system, AMAC designs and installs air conditioning sized to the actual load — not a rule of thumb.
What this covers
VRF/VRV system design
Multi-storey and multi-tenant buildings where dozens of indoor units run independently from shared outdoor plant.
Split and multi-split installs
Single-room and whole-floor systems for offices, retail units, server rooms and domestic properties.
Load calculations
Sizing worked from the building's real heat gains — glazing, occupancy, equipment and orientation — rather than a per-square-metre shortcut.
F-Gas certified handover
Refrigerant handling, leak testing, commissioning and documentation completed to F-Gas requirements.
Which system for which building
A rough guide. The survey decides it properly, but this is the conversation we'll have.
| System | Best for | Zones | Heating too | Capital cost | Watch out for |
|---|---|---|---|---|---|
| Split | Single room, server cupboard, small shop, bedroom | 1 | Yes | Low | One outdoor unit per indoor unit — wall space outside |
| Multi-split | Two to five rooms off one outdoor unit | 2 – 5 | Yes, all in the same mode | Low – mid | Can't heat one room while cooling another |
| VRF heat pump | Open-plan floors, retail units, clinics | Up to 64 | Yes, all in the same mode | Mid | Refrigerant charge in occupied rooms may need leak detection |
| VRF heat recovery | Mixed-use buildings with simultaneous demand | Up to 64 | Yes, per zone | Mid – high | Branch-box design has to be right first time |
| Close control | Comms rooms, labs, pharmaceutical storage | 1 – 4 | Rarely needed | High | Redundancy and alarms are the point — don't value-engineer them out |
Costs are relative, not quoted. Every job is priced after a free survey.
What a proper survey looks at
Heat gain
Floor area, glazing and orientation, occupancy, lighting, equipment and fresh air. Sized to the peak, not the average, so the system isn't short on the day it matters.
Electrical capacity
Incoming supply, spare ways on the board and cable routes. Found at survey, not on install day.
Pipe and condensate routes
How far the refrigerant pipe runs, how many bends, and where condensate drains to. Long or lifted runs affect capacity and are allowed for.
Outdoor unit position
Airflow clearance, noise to neighbours, planning considerations and access for maintenance — and whether it needs a frame, a cage or a roof check.
Typical sectors
Offices, retail, healthcare, education, data and comms rooms, industrial units, and high-specification residential.
Worth knowing
If you already know the room dimensions, the sizing calculator will give you an indicative kW requirement in seconds.
