Crying windows in winter reveals a need for better ventilation in your home. A home ventilation system improves the health of both your family and home by removing the moist, stale air that cause condensation, mould and mildew damage.
We have worked with many ventilation brands over the years and have selected the two best ventilation brands to work with based on their effectiveness, technology and support.
We have worked with a variety of leading ventilation brands and recommend SmartVent ventilation systems due to the superior performance, features and excellent back-up service. They have a range of systems including temperature and humidity sensing options. Smartvent has positive pressure as well as balanced pressure ventilation options.
Mitsubishi Electric is known for its heat pump systems yet also has a sophisticated home ventilation system called Lossnay. Lossnay is a balanced pressure ventilation system ideal for new air-tight homes.
We provide ventilation advice, quotes and installations in Northland, Auckland, Hamilton & throughout Waikato, Tauranga & Bay of Plenty, Palmerston North, New Plymouth, Wellington, Christchurch, Dunedin & Otago.
We provide ventilation advice, quotes and installation for most of the country with installation teams located in:
We can service your ventilation system to make sure it is working properly and efficiently. A great time to get your ventilation serviced is spring & summer to handle the high pollen season. We'll test and make sure everything is working properly and efficiently, give everything a good clean and tidy, and more. <Read More>
We have financial support available to make installing ventilation systems in your home more affordable. A home ventilation system is an investment in your family's health and protects your home from moisture related damage.
The main component of a ventilation system is the fan. A two-vent system costs around $15 per month running continuously - that's around 2c per hour. A 4-room system costs around 3c per hour. This estimate is based on 27c/kWhr.
Positive pressure systems push out the damp, stale air through gaps around doors and windows in older homes (pre-2000) and positively pressurise fresh, dry filtered air in from either the ceiling space or from outside into your home.
Unlike extractors, a positive pressure system can ventilate multiple rooms and is usually used as a whole home ventilation system, particularly in homes which are not tightly sealed.
They source air from the roof space (winter) or outside (summer) and use a fan with a filter to push air into your house creating a slight positive pressure displacing existing air with fresh air. These systems are good for reducing condensation and moisture which can contribute to mould, they also reduce heating and cooling costs by utilising freely available warmth from the roof space in the daytime in winter, and outside air at night in summer for cooling. This system works effectively in older homes but more airtight homes should consider a heat recovery or energy recovery system that draws the stale air out as it introduces fresh air.

Most ventilation systems rely on having a roof space to run the ducting to the various rooms. If you don't have a roof space your options are limited, however some options are:
Our standard ventilation systems can cover 1-6 rooms using one outlet per room. Additional kits can be utilised to extend to up to 12 rooms. Note that particularly large rooms may need more than one outlet.
Yes, ventilation will significantly reduce condensation but not necessarily eliminate it.
A positive pressure ventilation system introduces warm and dry air to push out moist air created from cooking, showering, breathing, laundry etc.
In the majority of situations a ventilation system will eliminate condensation however in some circumstances mechanical dehumidifiers are required to complete the job.
Many reverse cycle air conditioners (heat pumps) have a dehumidifying function. We recommend you check your heat pump user guide for instructions.
In new or tightly-sealed homes, a balanced system is needed as it removes moist, stale air while at the same time replacing it with fresh air.
Energy & heat recovery systems remove warm and damp air from living spaces and pass it through a heat recovery system (also known as a heat exchanger) to warm up dry, cool air which has been pulled in from outside.
These balanced ventilation systems have 1 fan to supply air to the home and 1 fan to remove air at the same rate - which creates gentle circulation and keeps the air filtered and fresh. There are whole home, single or multi-room solutions available. An Energy and Heat Recovery system is generally a balanced pressure system but can be configured to be either a slight positive or negative pressure system by adjusting the speed of the supply and exhaust air fans.
These ventilation systems are generally a balanced pressure system and work well in modern, tightly sealed homes and are most effective when used in conjunction with properly sized heat pumps.
These systems can be used for whole home or single room applications to maintain indoor air quality and transfer the energy of incoming supply air through a heat exchanger with outgoing exhaust air being expelled from the home.
The difference between the two is the type of material used in the heat exchanger core - HRVs are better in dry environments and ERVs are best in humid environments. Depending on your local climate zone, we can help select the best recovery system for your home.
We have a range of ventilation systems available to suit most budgets starting from $2,129 installed for a SmartVent Lite system.
It doesn’t matter how dirty the air is in your roof space, the high quality filters in the ventilation system will remove dust and any airborne particles to ensure only fresh, filtered air is transferred into your home, keeping it clean and healthy.
Dust, pollen, bacteria, smoke (from cooking) and other airborne particles are filtered by the ventilation system.
SmartVent filters are recommended to be changed every 12 months for maximum effectiveness but your controller will indicate when it is necessary.
Charcoal and HEPA filters usually require 6 monthly changes.
The great aspect about SmartVent filters is that you can easily change them yourself, alternatively we offer a full filter change and service check. Read more here.
Depending on the ventilation system you have, there are filter cartridges, carbon filters or HEPA filters available. They do need changing every 6-12 months depending on the type, and are extremely efficient in preventing the spread of airborne bacteria, odours, pollutants, particles, dust, pollen and allergens.

The ventilation system has proved, frankly, miraculous in eliminating our top priority issues of a) regular, persistent morning window condensation on wintry mornings, and (b) recurrent mould on curtains, behind settees, besides cupboards, and besides bookshelves.
