Question 1

Why does my home get so much condensation?

Accepted Answer

Condensation forms when warm, moist air inside your home meets a cold surface, such as a window or wall. In New Zealand, this is especially common in winter when homes are heated but poorly ventilated. Cooking, showering, and even breathing add moisture to the air, and without a way for that moisture to escape, it builds up and settles on cold surfaces.

Question 2

How does mould start growing in my home?

Accepted Answer

Mould needs three things to grow: moisture, a food source (like dust, wood, or paint), and the right temperature. New Zealand homes provide all three in spades during winter. Once relative humidity consistently sits above 60 to 70%, mould spores that are naturally present in the air will start to colonise surfaces. Ventilation reduces that humidity and deprives mould of the moisture it needs.

Question 3

Is a damp home actually a health risk?

Accepted Answer

Yes. Research consistently links damp, mouldy homes to respiratory conditions including asthma, rhinitis, and bronchitis. Children and the elderly are particularly vulnerable. Beyond respiratory health, mould produces mycotoxins that can cause fatigue, headaches, and skin irritation. Addressing the root cause, excess moisture, is the most effective way to protect your family's health.

Question 4

What is a home ventilation system?

Accepted Answer

A home ventilation system draws filtered air from outside (typically from the roof space, which is warmer than outside air in winter) and distributes it through your home. This positive pressure pushes stale, moist air out through gaps around doors and windows. The result is a continuous cycle of fresh air that keeps humidity levels in check and reduces condensation and mould.

Question 5

How is HomeVent different from just opening windows?

Accepted Answer

Opening windows works, but it's impractical in winter. You lose heat along with the moisture. HomeVent systems use the drier, naturally warmer air from your roof cavity, which means you're ventilating without the heat loss. The air is also filtered before it enters your living areas, removing dust and pollen that you'd get from an open window.

Question 6

Will HomeVent work in my type of home?

Accepted Answer

HomeVent systems are designed to work in most New Zealand homes, including older villas, brick-and-tile homes, and modern builds. The key requirement is an accessible roof space. During your free assessment, our consultant will determine the right system size and configuration for your specific home layout and needs.

Question 7

Does HomeVent meet the Healthy Homes Standards?

Accepted Answer

HomeVent aligns with the ventilation requirements of New Zealand's Healthy Homes Standards. It continuously brings filtered air in from outside and creates gentle positive pressure that pushes damp, stale air out, exactly the kind of effective mechanical ventilation the standards are designed to encourage. For rental properties, it's a simple, set-and-forget way to help meet your ventilation obligations while keeping the home drier and healthier. During your free assessment we'll confirm the right configuration for your property.

Question 8

How long does installation take?

Accepted Answer

A standard HomeVent installation typically takes between 2 and 4 hours, depending on your home's size and layout. Our certified installers work efficiently to minimise disruption, and the system is fully tested before they leave. Most homeowners are pleasantly surprised by how quick and tidy the process is.

Question 9

Do I need to be home during the installation?

Accepted Answer

Yes, we ask that an adult be present during installation. Our installer will need access to your roof space and the rooms where ceiling vents are being fitted. Once the system is installed, they'll walk you through how to use the control panel and answer any questions you have.

Question 10

Will installation damage my ceiling or walls?

Accepted Answer

Installation involves fitting small ceiling vents (typically around 150mm diameter) in each room. These are neatly finished and blend into your ceiling. No wall penetrations are needed. Our installers take care to keep your home clean and tidy throughout the process, and leave the site as they found it.

Question 11

How much does a HomeVent system cost?

Accepted Answer

System pricing varies depending on the size of your home and which system is recommended for your situation. We provide a free, no-obligation quote after your home assessment. Our consultant will explain exactly what's included and there are no hidden fees. Contact us or find an installer near you to get started.

Question 12

What does it cost to run the system day to day?

Accepted Answer

HomeVent systems are designed to be extremely economical to run. Most systems cost just $20 to $40 per year in electricity, roughly 5 to 10 cents per day, thanks to our high-efficiency EC motors. When you factor in savings from reduced heating costs and avoided mould remediation, the system typically pays for itself within a few years.
