Clear condensation, mould and stale air from your Wellington home
Modern Wellington homes with aluminium joinery and double glazing hold warmth in well, but they also seal in cooking steam, shower moisture and stale air with nowhere to escape.
Left unchecked, that trapped moisture shows up as condensation on windows, black mould in corners, musty smells, damp bedding and indoor air that can aggravate asthma and allergies.
Abode installs balanced ventilation systems such as the Mitsubishi Lossnay, which extract moist, stale air and replace it with fresh, filtered air. Heat recovery keeps warmth inside during winter instead of losing it through an open window, improving air quality while helping manage condensation and moisture. When paired with a correctly sized heat pump, a balanced ventilation system creates a healthier, more comfortable home all year round.

Ventilation Systems - Overview:
Abode Air Conditioning Ltd designs and installs home ventilation systems, including balanced heat recovery ventilation and positive pressure ventilation, for Wellington homes.
- Balanced heat recovery ventilation using Mitsubishi Lossnay units with heat exchanger cores
- Positive pressure ventilation suited to older timber-framed homes with natural gaps
- Whole house ventilation or single-room solutions matched to each layout
- Ducted installations designed around ceiling cavities, roof pitch and under-floor access
- Free site consultation with engineer-designed air ventilation system recommendations
- Annual servicing covering filters, ducting checks, airflow testing and core cleaning
Balanced home ventilation systems
- Whole house ventilation systems that reduce condensation, mould and mildew
- Heat recovery ventilation delivers fresh, dry air without opening windows
- Free consultation with ventilation designed around your home's layout
Home ventilation systems installed across the Greater Wellington region, including Hutt Valley, Porirua, Kapiti, Levin and Masterton.
Common signs of a ventilation problem
Mould around window frames, mildew on ceilings, condensation on the glass in the morning, damp cold pillows and stuffiness in newer homes all point to stale, moist air with nowhere to go. Over time, excess moisture settles into bedding, furnishings and building materials, affecting both comfort and indoor air quality.
Mould spores affect breathing, damp fabric never dries and the house feels heavy.
Home ventilation systems tackle the cause by moving moist air out and drawing dry, filtered air in. Filters capture dust, pollen and particulates before air enters living spaces, which matters where asthma, hay fever or allergies exist.
Where whole-home heating and cooling is considered, ventilation is often planned alongside residential climate control.

Balanced ventilation with heat recovery for airtight homes
Older timber-framed houses breathe through gaps around doors, windows and floors, so positive pressure systems like HRV and DVS work there: filtered air in, stale air out through gaps.
Newer airtight homes with aluminium joinery and double glazing differ. Often there aren't enough gaps for stale air to escape, so positive pressure systems may be less effective in airtight homes. Balanced ventilation extracts stale air and adds equal fresh filtered air, suiting modern homes.
Opening a window in Wellington's winter freshens air but loses heat. Heat recovery solves that: the Mitsubishi Lossnay transfers warmth from stale to fresh air. Every install suits the home's layout, using our in-house HVAC design approach.

Free consultation, engineered design and annual maintenance
Not sure whether a whole-house ventilation solution or single-room fix suits your situation? A free, no-obligation consultation and site visit is available year-round. We assess the building, review visible signs, check cavities for ducting and recommend the right system.
If ducted ventilation isn't practical because of the home's construction or roof space, we'll recommend an alternative solution that better suits the property.
Most installations take one to two days. Once installed, servicing at least every 12 months covers:
If ducted ventilation isn't practical because of the home's construction or roof space, we'll recommend an alternative solution that better suits the property.
Most installations take one to two days. Once installed, servicing at least every 12 months covers:
- Cleaning or replacing filters
- Checking ducting for disconnections
- Confirming airflow at each outlet
- Cleaning Lossnay heat exchanger cores
- Reviewing motor and controls
Site delivery around your operating hours
Commercial air conditioning installation shouldn't halt operations. Abode liaises with your project manager rather than running the job, and prefers being among the first trades because ducting and equipment are bulky. To minimise disruption, work can be scheduled around business hours:
- After-hours shifts, like a Mana job from 5pm over two nights
- Weekend or public holiday work
- School and kindergarten jobs during term breaks
- Floor-by-floor phasing in hotels and apartments
Electrical work is handled by qualified in-house electricians and every installation includes a Code of Compliance certificate.
Home ventilation systems continuously replace stale, moist indoor air with drier, filtered air. This reduces condensation on windows, lowers humidity, removes airborne pollutants and helps prevent mould growth.
Filters capture dust, pollen and particulates before the air reaches your living spaces, which is particularly helpful in households affected by asthma, hay fever or allergies.
Positive pressure ventilation pushes filtered air from the roof cavity into the home, forcing damp air out through gaps around doors and windows. Heat recovery ventilation is a balanced system that draws fresh air in while extracting stale air, using a heat exchanger to transfer warmth between the two airstreams so most of the indoor heat stays inside.
Heat recovery ventilation helps by recovering warmth from outgoing air and reducing indoor humidity, so a heat pump or heater works less hard to keep rooms comfortable - dry air heats faster than damp air.
Positive pressure systems can also draw on warm air trapped in the roof cavity during sunny days, depending on the home.
Most residential installations take one to two days, depending on the number of rooms, ceiling access and system type. Positive pressure systems are generally quicker, while balanced heat recovery ventilation involves more ducting and a dedicated unit.
Roof space, ceiling cavities and room layout are surveyed beforehand so ductwork is planned accurately.
Filters should be checked and cleaned or replaced at least every 12 months, and the main unit benefits from an annual service to review motor performance, ducting and controls.
Heat recovery ventilation systems also have a heat exchanger core that needs periodic cleaning to maintain airflow and heat transfer. Disconnected ductwork and poor airflow are also checked during servicing.
