MVHR design, installation & commissioning
MVHR quietly supplies filtered outdoor air to bedrooms and living rooms while removing stale, humid air from bathrooms, the laundry and kitchen.
HiPer Haus designs the system around your building, installs it carefully and measures every airflow before handover.
The right MVHR approach depends on the building stage, available space and the people who will live there.
01 · New build or major renovation
We size the system, plan the duct routes and coordinate the details with your builder and designer before structure, ceilings and cabinetry make the decisions for you.
Plan a new-build system02 · Existing home
Some homes suit a central ducted retrofit. Others are better served by decentralised through-wall units. Access, room layout and the building envelope decide which approach makes sense.
Discuss an existing home See the Nairne retrofit03 · Builder, architect or designer
We provide design information, coordinate penetrations and duct routes, install the system and document the commissioned airflows for handover or certification.

At Wynn Vale, the Zehnder Q350 and ComfoTube ductwork were coordinated inside a Pro Clima Intello airtight dropped ceiling. The system stayed within the thermal envelope, remained accessible and avoided last-minute clashes with the structure and insulation.
HiPer Haus designed, installed, balanced and commissioned the system. The project team received measured airflow data rather than an assumption that the factory settings would be close enough.

Commissioned airflows
MVHR is not a box that can be selected in isolation. The unit, ducts, terminals, controls, building envelope and commissioning all have to work together.
Airflow rates, occupancy, room use, unit location and service routes are considered together.
The equipment is selected for the home, not because it happens to be sitting on a supplier shelf.
Routes, terminals, silencers, external grilles and airtight penetrations are resolved before site work.
The unit, ductwork, controls and terminals are installed as one system, with access for future maintenance.
Every supply and extract terminal is measured and balanced against the design — not left at a factory setting.
You receive the operating settings, commissioning information and a clear plan for filters and maintenance.
Nobody wants to remember which windows to open at 11pm in July. A well-designed MVHR system quietly handles the ventilation in the background.
Filtered outdoor air is supplied to bedrooms, living rooms and other occupied spaces.
Stale air is removed continuously from bathrooms, the laundry and kitchen zone.
The air does not mix, but much of the heat is transferred before the stale air leaves the building.
Jonathen Hindry
Founder, HiPer Haus
I’m Jono. My background combines more than 25 years on the tools with MVHR design, airtightness testing and Passive House construction.
That matters because good ventilation is decided in the details: where a duct crosses the air barrier, whether a silencer can actually fit, how the filters will be changed and whether the measured airflow matches the design.
01
We look at the plans, household, airtightness target and the available routes through the building.
02
We size the airflows, select the system and issue a coordinated layout for the project team.
03
The unit, insulated ductwork, terminals, controls and external connections are installed carefully on site.
04
We measure and balance every terminal, document the result and show you how to operate the system.
