The right ventilation system clears the condensation, damp and mould that build up in Kiwi homes, and brings in a steady supply of fresh, filtered air. Drier air is easier and cheaper to heat, so your home feels warmer for less. Professionally designed and installed in Auckland and Dunedin.

Ventilation removes the moist, stale air that causes condensation on your windows and mould in your wardrobes and ceilings. By continuously replacing it with drier air, a ventilation system keeps humidity under control across the whole house, not just the rooms where you can see the problem.
Cleaner air is easier to breathe. Centralised systems filter incoming air through high-grade F7 filters that capture up to 90% of fine particles down to 0.4 microns, including pollen, dust and other allergens, with HEPA filtration available for allergy and asthma sufferers. A drier home also means fewer dust mites and less mould, two of the most common triggers in New Zealand homes.
Dry air is far easier to heat than damp air, so a well-ventilated home reaches a comfortable temperature faster and holds it for less. Heat recovery systems go a step further, capturing warmth from the air being expelled and using it to pre-warm the fresh air coming in, so you are not heating your home from cold every time.
The most common home ventilation system in New Zealand. A single fan draws fresh air from the roof cavity, filters it, and distributes it through ceiling diffusers into your living spaces. The gentle pressure this creates pushes the moist, stale air that causes condensation out through gaps around windows and doors.
Best for: most standard homes, homeowners wanting an effective, affordable way to control condensation and dampness, and anyone after a set-and-forget system, with optional heat transfer and tempering add-ons.
The most energy-efficient option, and the best fit for modern, airtight homes. A balanced system uses two air streams: one fan brings filtered fresh air in from outside, while another extracts an equal volume of stale, humid air. As the two streams pass through a heat exchange core, up to 90% of the warmth in the outgoing air is recovered and used to pre-warm the incoming fresh air, so you ventilate without throwing your heating away.
Best for: new builds and well-insulated homes, and anyone who wants maximum comfort and efficiency. Pairs especially well with a ducted heat pump: a Mitsubishi Lossnay system can be linked to your heat pump so fresh air and climate control work together for a drier home that heats faster.
The most targeted form of ventilation, fitted right where the moisture is created. A quality extractor fan removes steam and humidity at the source in bathrooms, kitchens and laundries before it spreads through the house. Modern fans are quiet, efficient, and built to meet New Zealand’s G4 Building Code and Healthy Homes Standards
Best for: bathrooms and kitchens in any home, new builds (where extraction is now required), and rental properties that need to meet the Healthy Homes ventilation standard.
Our customer rarely install ventilation alone. A drier home is cheaper to heat, so ventilation and a heat pump make each other better, and running both on your own solar power makes them cheaper still.
Generate your own power and cut your electricity bill from day one.
Store excess solar power to use at night, and during outages.
Warmer winters, cooler summers, and cleaner air for your family.
Cut your water heating costs by about 60% compared with a traditional electric or gas cylinder.
Charge using solar during the day or overnight on stored solar energy or off-peak grid energy and stop paying at the pump.
At Future Energy, we look at your energy footprint and individual priorities, and provide independent advice on the best solutions.
A home ventilation system continuously replaces the moist, stale air inside your home with drier, filtered air from outside or the roof cavity. This controls the condensation, damp and mould that build up when a household's everyday moisture (up to 3,500 litres a year from cooking, showering and breathing) has nowhere to go. The result is a drier, healthier home that is easier and cheaper to heat.
Positive pressure ventilation uses one fan to push filtered air, usually drawn from the roof cavity, into the home, forcing stale air out through small gaps. It is the most common and most affordable option. Balanced pressure (heat recovery) ventilation uses two fans: one brings fresh air in from outside, the other extracts an equal volume of stale air, and a heat exchange core recovers up to 90% of the warmth from the outgoing air to pre-warm the incoming air. Balanced systems cost more but are more efficient and better suited to modern, airtight homes.
Yes. Condensation and mould are caused by too much moisture in the air with nowhere to escape. A ventilation system removes that humid air continuously and replaces it with drier air, which stops condensation forming on cold windows and walls and removes the damp conditions mould needs to grow. For the best result, ventilation is paired with adequate heating, because warm, dry, well-circulated air is the combination that keeps a home mould-free.
Yes. The Healthy Homes Standards require rental properties to have appropriate ventilation, including extraction fans that vent outside in rooms with a bath, shower or indoor cooktop. New builds must also meet the G4 Building Code, which sets minimum extraction for bathrooms and kitchens. We design compliant ventilation for both rentals and new builds, and several SmartVent systems include a rental property lock so the system cannot be switched off.
Pricing depends on the type of system and the size of your home. An extractor fan installation is the lowest cost, a positive pressure system is the most affordable whole-home option, and a balanced pressure (heat recovery) system sits at the upper end because it uses two fans and a heat exchange core. We give you exact pricing in writing at your free Home Energy Consult, once we have looked at your home's size, layout and roof space.
It depends on your home and what you want to fix. For most existing homes with a condensation problem, a positive pressure system is the effective, affordable answer. For modern, airtight or newly built homes, a balanced pressure heat recovery system gives the best comfort and efficiency. For targeted moisture in bathrooms and kitchens, or to meet Healthy Homes requirements, quality extractor fans are the right tool. We will match the system to your home at the free consultation.
Yes, and it works better when it does. A drier, well-ventilated home is easier to heat, so ventilation reduces the load on your heat pump. A Mitsubishi Lossnay heat recovery system can be linked directly to a Mitsubishi Electric ducted heat pump so the two run as one system. And because ventilation runs on electricity, pairing it with solar means your fresh air and climate control can run largely on your own power.
Modern systems are quiet. A Mitsubishi Lossnay unit runs from as low as 14dB, quieter than a whisper, and quality extractor fans are engineered for low noise. Maintenance is minimal: filters need cleaning or replacing periodically (your system will remind you, or we will show you how), and we recommend a periodic check to keep everything running at its best. We cover all of this at handover, and our service team supports your system long after install.
From green energy loans to interest-free options, we will help you find a payment structure that suits your budget. A drier, better-ventilated home is also cheaper to heat, so the system starts paying you back in lower power bills. Talk to us about finance at your free home consultation.
