ServicesA-02
Five disciplines, carried under one contract
Each of these is a full scope we deliver ourselves, from calculation through to the test record. Most projects use more than one, which is the reason they are not sold separately.
- 01
HVAC Design & Heat Load Calculations
Air-conditioning and ventilation systems sized from a calculated load rather than from a catalogue, through to equipment selection and duct design.
- Heat-load calculations
- HVAC system design
- Duct and piping design
- AHU, chiller and VRF selection

Testing & Qualification
The measurements that prove a room performs: HEPA integrity, velocity, air changes, differential pressure and the IQ/OQ/PQ documentation behind them.
- HEPA integrity (PAO/DOP) testing
- Air velocity and air-change verification
- Differential pressure testing
- IQ/OQ/PQ documentation

ProcessA-04
Requirement to handover, in five phases
Each phase closes on a document before the next one opens. That sequence is what makes the last phase possible at all. A performance result on an installation that was never formally verified cannot be defended in an audit.
01
Requirement
What the rooms have to hold, what happens inside them, and which standard governs. Usually from a layout, a URS or a walk-through of the existing facility.
Requirement summary and applicable standard
02
Engineering & Design
Heat load, air volumes, classification and pressure relationships are calculated first. Equipment, ducting and enclosure are selected from those numbers, not before them.
Design package, drawings and equipment schedule
03
Execution
Fabrication, installation and site coordination for the HVAC and the enclosure together, phased around whatever else is happening in the building.
Installed system and as-built drawings
04
Testing & Validation
Balanced first, then measured: velocities, air changes, differential pressures, filter integrity, temperature and humidity, each recorded against a location and a date.
Test records and IQ/OQ/PQ documentation
05
Handover & AMC
Documentation handed over, operators shown the system, and a maintenance scope agreed that keeps the rooms in the state they were signed off in.

Why AirvonA-05
What single-contract delivery actually changes
Most facility problems we are called in to fix are handover problems: the consultant drew it, someone else built it, and nobody owned the gap between the two.
- 01
Single-point accountability
Design, execution, commissioning and support are coordinated through one engineering team. There is no gap between the consultant who drew it and the contractor who built it, because they are the same people.
- 02
Documentation-driven delivery
The qualification requirement is fixed at design stage and carried through, so the paperwork an auditor asks for is produced by the project rather than assembled after it.
- 03
Tested before handover
Systems are balanced, measured and recorded before completion. Velocities, air changes, differential pressures and filter integrity are figures on a page, not assurances.
- 04
Lifecycle support
Rooms drift out of qualification quietly. AMC and retrofit scopes are built around filter management, rebalancing and re-qualification, so the facility keeps holding what it was signed off holding.
Engineering insightsA-06

Start a projectA-07
Have a layout, URS or BOQ? Send it to our engineering team.
Area, classification if you know it, and what happens inside the room is enough to start. If the building does not exist yet, the architectural plan is enough.
Or call us directly. Most projects start on the phone
What happens next
- 01
An engineer reads it
Not a form handler. Within one working day.
- 02
We ask three or four questions
Usually the ones that decide the whole design, before they decide the cost.
- 03
You get a written scope
With the standards it would be built against. No cost, no obligation.
