Don't just take our word for it.

Same quality system.
No sales team markup.

The big ventilation brands charge more — not because their systems are better, but because of how they run their businesses. We've installed ventilation systems across Dunedin and the wider Otago region, and we know what Dunedin homes need: reliable, honest solutions that actually work in our cold, damp winters. By cutting out the sales teams, TV ads, and in-home consultations, we pass those savings directly on to you.

No sales team, no commission

No door-to-door reps, no pushy in-home consultations, no referral fees. You get a fixed price online in minutes — no sales visit required.

No big advertising budget

While the big brands sponsor sports teams and run TV campaigns, we grow through word of mouth and honest reviews — and pass that saving on to you.

No wall control panel — and that's okay

Most customers with control panels rarely touch them. Our system automatically adjusts between summer and winter modes — there's nothing to programme or manually switch. It's one genuine area we save on cost, with no impact on how well the system works.

High-quality components, 6-year warranty

We use reliable, high-grade components chosen for the New Zealand climate. Every installation is backed by a 6-year warranty, and we've installed over 1,000 systems across the country.

Home Ventilation Systems Dunedin

Dunedin homes are no strangers to damp and cold — and that's exactly what Better Vent was built for. Our ventilation systems help Dunedin homeowners improve air quality by reducing moisture, condensation, and mould, simply and effectively.

Dunedin's cold, wet winters create the perfect conditions for moisture to build up inside homes, and where there's moisture, mould isn't far behind. Better Vent's system uses a hospital-grade F8 filter and energy-efficient fan to push clean, dry air through your home, helping create a warmer, healthier environment year-round.

It's also designed to work without any input from you. No complicated controls, no seasonal adjustment — just quiet, automatic operation and consistent performance you can count on, even through a Dunedin winter.

Frequently Asked Questions

Common questions about Better Vent and home ventilation in Dunedin.

How much do replacement filters cost?

You can buy new filters from us, online or from Bunnings for $55 plus shipping.

Can I replace the filters myself?

Yes! Replacing filters is easy to do yourself and won't affect your warranty with us.

How often do filters need replacing?

We recommend replacing filters every 2 years.

Why are you more affordable than other ventilation systems in Dunedin?

The same reasons we're more affordable everywhere — no door-to-door sales teams, no TV advertising, and no expensive in-home consultations. We quote online and keep our overheads low, passing those savings directly on to Dunedin homeowners. You get the same quality system as the big brands, at a significantly lower price.

Can you install a control panel on the wall?

We don't offer a wall control panel option. Our system runs fully automatically and therefore doesn't need one. Most customers find they never use them anyway. We can install a wall switch to give you manual on/off control.

Can you install extractor fans and rangehoods as well?

Yes we can! Get in touch and we can give you a price.

Do you offer a Summer add-on?

We don't recommend them. Unfortunately even with a Summer add-on taking air from outside, the air entering your home will be warm as all the ducting is in the hot roof space.

How much does it cost to run?

On average, for a typical 4 outlet system, our system draws less than 10 watts of power. Assuming you pay $0.30/kwh, it costs less than $3 a month to run!

How does the system work?

All positive pressure ventilation systems work in a similar way. Our system takes dry air from your roof space and uses it to displace the damp air in your home. During the day, the fan unit runs at full speed to make the most of the warm roof space air. At night the air is cooler, so the fan runs at a low speed — just enough to avoid condensation forming. There's no cold draughts — most people never notice it's running.

Our automatic smart sensor takes care of everything! And in Summer it turns the fan off so you don't have hot air blowing into the house.
