Heat-recovery ventilation (HRV & MVHR)
Balanced whole-home systems that bring in filtered fresh air, extract stale moist air and recover heat that would otherwise be lost—particularly valuable in modern airtight homes.
Ventilation & Cooling · Wānaka & Queenstown
Air a home can breathe.
Fresh, filtered air and steady summer temperatures. Balanced ventilation and cooling that keep a healthy home calm and dry, without noise or draughts.
Balanced ventilation, MVHR heat recovery and cooling for new and existing homes across Wānaka and Queenstown, designed with the heating as one system.
The better a home is built, the more its air must be designed. High-performance homes are sealed tight, so fresh air, moisture control and summer cooling have to be planned, not left to open windows. We design ventilation alongside the heating so the whole climate of the home works together.
What we do
Demand-controlled & home ventilation
Systems designed around the home and its occupants, including demand-controlled ventilation that responds to moisture and occupancy while helping reduce condensation, mould and indoor pollutants.
Ambient & radiant cooling
Water-based cooling through underfloor pipework or active ceiling panels, using the heat pump in reverse to remove heat quietly without the draught of a conventional air-based system.
Air conditioning
High-wall units or forced air delivered through ceiling and wall vents, selected and sized where an air-based heating and cooling system is the best fit.
Ventilation servicing & filter care
Maintenance for home ventilation systems, including filter replacement and help diagnosing reduced airflow, excess noise and other performance issues.
