Drier air. Clear windows. A healthier home all winter.
Reply within one working day, often the same morning.
If you’re wiping streaming windows every winter morning, finding mould creeping across south-facing walls or opening wardrobes that smell musty, your home has a moisture problem – and a Palmerston North winter makes it worse every week. A home ventilation system fixes the cause: it continuously replaces the damp, stale air inside your home with drier, filtered air, so moisture leaves before it can condense.
We supply and install the SmartVent positive pressure range – Lite+, Positive3 and Positive Advance – with systems sized from a single room to twelve, covering homes up to 560 m², every one backed by SmartVent’s 5-year warranty. These are the same systems our parent team Budget Electrical installs every week, fitted and certified here by our own registered electricians.
And because we’re a heating and ventilation team in one, you get straight answers about the whole picture: ventilation to dry your home, a heat pump to warm it, and servicing and filter replacement for whatever system you already own – HRV and DVS included. One expert team, across Palmerston North, Feilding, Ashhurst and the wider Manawatū.
A positive pressure system works by drawing drier air from your roof cavity, filtering it, and gently pushing it through ceiling outlets into the rooms that need it - which forces the damp, stale air out through the home's natural gaps. It only works properly when it's sized to your floor area, the outlets serve the right rooms, and the sensors are set up correctly. That's the job we do.
No more streaming windows. No musty wardrobes. No mould creeping back every July.
The Lite+ is a centralised positive pressure system with temperature and humidity sensing at two points – inside your home and in the incoming air stream – so it automatically adjusts airflow to the conditions instead of blowing blindly. Low-temperature protection, boost control, a daily scheduler and a filter change alert are all built in.
For landlords, the Lite+ has a feature the damp-rental problem was waiting for: a rental property lock. Tenants can adjust comfort settings but can’t switch the system off – so the home stays dry, and the mould complaints stop. With almost a third of New Zealand rental homes reported as feeling damp, it’s a small investment in protecting a big one.
The range scales from a single bedroom to a twelve-room home (up to 560 m²), and every system carries SmartVent’s 5-year warranty. If the budget is tight or the property is an investment, this is the honest recommendation – the Lite+ simply isn’t compatible with the comfort add-ons, and we’ll tell you if that matters for your home.
The Positive3 watches temperature and humidity in three places, inside your home, in the roof cavity and outside – using wireless sensors that sit exactly where they should rather than where the cabling allows. From those readings it runs dew point control: introducing precisely enough drier air to keep your windows above the temperature where condensation forms.
It’s built to run quietly and cheaply: energy-efficient brushless EC fans, acoustically and thermally insulated ducting, and full control from the SmartLife phone app or the wall controller. The rental lock, boost mode, scheduler and filter alerts carry over from the Lite+.
This is also where the comfort add-ons open up: a tempering heater (1 kW or 2 kW) to take the chill off incoming winter air, a heat transfer option to move warmth from your heat pump or fire into the bedrooms, and a flexi air source for summer. Sized from one room to twelve, 5-year warranty – for most Palmerston North family homes, this is the system we end up recommending.
SmartVent Positive3 · Most family homesThe Positive Advance is SmartVent’s market-leading system. Four wireless temperature and humidity sensors measure conditions throughout the home, in the roof cavity and outside, continuously calculating the dew point and deciding exactly how much fresh air to introduce before condensation can form on your windows.
Where the Positive3 is smart, the Advance is set-and-forget: weekly scheduling instead of daily, an intuitive wall controller plus the SmartLife app, and automation that manages the whole home’s moisture without you touching a thing. The same quiet EC fans and insulated ducting, the same tempering heater, heat transfer and flexi air source add-ons – with the most complete control in the range.
It suits larger family homes, two-storey layouts and anyone who wants the moisture problem handled permanently and invisibly. And our honest rule applies here like everywhere: the free home assessment decides which tier your home actually needs. If a Positive3 will keep your windows clear, we won’t sell you an Advance.
SmartVent Positive Advance · Full automationA ventilation system only fixes your damp problem if it’s sized, ducted and set up properly. An undersized system churns away without ever clearing the moisture. Outlets in the wrong rooms ventilate the hallway while the bedrooms stay damp. And a controller that’s never configured just moves air around at random.
Our home ventilation service is built around three commitments.
A ventilation install is largely an electrical job – fans, controllers, wireless sensors and often a tempering heater, all wired into your home. Ours are installed and certified by our own registered electricians, the same team that fits these systems every week as Budget Electrical.
That means the wiring is done once, done right and signed off properly – no second contractor, and no shortcuts hidden in your roof cavity.
The free assessment looks at your floor area, room count, roof cavity and where the moisture actually comes from – then we recommend the tier and size your home needs. SmartVent’s range runs from one outlet to twelve, so there’s no forcing your house into the wrong system.
Outlets go where they earn their keep: the bedrooms where your family breathes all night, not just the easy spots. And if the Lite+ will solve it, we won’t quote you an Advance.
No handover until the system is commissioned: sensors placed where they read true, airflow checked at every outlet, dew point control configured, and the schedule programmed with you – including the rental lock if you’re a landlord.
Then we stay useful: SmartVent’s 5-year warranty registered, filter replacement and servicing when it’s due – for your new SmartVent or the HRV or DVS you already own.
Every home ventilation quote is a fixed, itemised installed price, system, ducting, outlets, electrical work and GST. What moves the number is your floor area, the number of outlets, roof cavity access, duct routes and any comfort add-ons. The free home assessment settles all of it before you commit.

We walk the house with you – where the condensation shows, where the mould starts, floor area, room count and the roof cavity the system will live in.
Lite+, Positive3 or Positive Advance, sized to your home with outlets in the rooms that need them. You get a fixed, itemised quote – system, install, electrical and GST.
Most homes are done in a single visit. We confirm the day before and turn up when we say we will.
The unit and insulated ducting go into the roof cavity, ceiling diffusers are cut cleanly, and every room is left tidy – drop sheets down, dust vacuumed, packaging gone.
Fans, controller, sensors and any tempering heater are wired and certified by our own registered electricians. No second contractor needed.
Wireless sensors placed where they read true – living areas, roof cavity, outside, then airflow checked at every outlet and dew point control configured for your home.
SmartLife app connected, schedules programmed with you, filter alerts explained – and the rental lock set up if the home’s an investment property.
SmartVent’s 5-year warranty registered, and filter replacement and servicing when the system says it’s due. One local team, one call.
It depends on your floor area, how many rooms need outlets, roof cavity access and whether you add comfort options like a tempering heater. That’s why we quote after a free home assessment – the price you approve is fixed and itemised, covering the system, installation, certified electrical work and GST.
As context: a ventilation system usually costs far less than the repainting, curtain replacement and mould treatment that damp quietly causes – and it protects the house every day after.
That’s precisely what it’s designed to do. SmartVent’s dew point control measures conditions inside, outside and in your roof cavity, then introduces just enough drier, filtered air to keep surfaces above the temperature where moisture condenses. Windows clear within days of installation in most homes. Severe cases, unheated homes, failed joinery, sometimes need heating in the mix too, which is exactly the conversation the free assessment sorts out.
HRV and DVS are brand names most Kiwis know – like SmartVent, they’re positive pressure home ventilation systems. We install the SmartVent range because of its sensor-driven dew point control, energy-efficient EC fans and 5-year warranty – and we service and replace filters on existing HRV and DVS systems across Palmerston North, so whichever brand is in your ceiling, we’re your local team.
As a guide: Lite+ for rentals and tighter budgets, Positive3 for most family homes, and Positive Advance for larger homes and set-and-forget automation with four sensors. All three scale from one room to twelve. The free assessment matches the tier to your actual home – never the other way around.
No – it dries it, which makes the house cheaper to heat, because drier air warms faster and holds warmth better. If incoming winter air feels cool, a tempering heater add-on takes the chill off, and a heat transfer option can move warmth from your living-area heat pump into the bedrooms. Ventilation and heating work best as a pair: one dries, one warms.
This is one of the strongest cases for a system. Almost a third of New Zealand rental homes are reported as feeling damp, and the SmartVent rental property lock means tenants can adjust comfort settings but can’t switch the system off – so the home stays dry between tenancies and inspections. It’s a one-day install that gets ahead of mould complaints, protects your paint and joinery, and shows tenants (and the Tenancy Tribunal, if it ever comes to that) you’ve taken moisture seriously.
