Ventilation system servicing and maintenance in Auckland: restore air quality and keep your home dry.
We service and maintain positive pressure, balanced & heat recovery ventilation and extractor systems across Auckland. Maintenance only. We don’t sell or install new units, so our only interest is in how well your existing system performs.
Your ventilation system repair & maintenance comes from a company that doesn't sell or install new units.
The Healthy Home Blindspot.
New Zealand Building Guidance recommends a minimum of 0.35 air changes per hour in occupied rooms: the rate at which fresh air replaces stale air. When that rate drops, CO₂ from normal breathing and pollutants from everyday activity build up rather than being displaced. Bedrooms get stuffy overnight. Condensation returns as moisture removal falls behind. The fan is running, but the air quality has quietly declined.
These systems were bought to make homes healthier. When they're not serviced, some stop delivering on that. A few make things worse.This is the Healthy Home Blindspot.

The MiHT Care Protocol.
Every MiHT visit is carried out by a qualified ventilation technician and follows the same five-stage process. It was built around a gap we kept seeing in the industry: homeowners paying for a service with no way to know what they actually got, or whether their systems were any better for it.
PLAN
Tell us which units you want serviced. Your price is calculated instantly.
You see exactly what is included and what it costs before you confirm anything.
Pick a time that suits you and book it yourself. Any time of the day or night.
UNCOVER
Before any work starts, every unit is photographed and its condition recorded. Your system's current airflow performance and component condition are documented before anything is touched. That starting point is what allows us to show you, at the end of the visit, exactly what the service achieved and what, if anything, still needs attention.
RESTORE
Your service follows a documented checklist built on industry best practice. Every booked unit has its key components cleaned thoroughly: filters, fan housings, ducting connections and diffusers. The contaminants that have built up since install or the last clean are removed so your system delivers the air changes it was designed for.
REVIEW
Once the work is done, you receive a written condition report with before and after photos of every unit we serviced. The photos focus on the areas that needed the most attention, and the report shows your system's pre and post service condition so the full improvement is documented. Any issues that need attention are noted clearly, whether that's a repair your system needs or something to keep an eye on at the next service. It is a complete record of your system's condition, yours to keep.
PROTECT
Once your service is complete, we take care of what comes next. Annual Care Plan customers have their next service automatically scheduled. We manage the timing, send the reminders, and book the visit. For one-off customers, we send a reminder when your system is next due so you never have to remember when you last had it serviced. Either way, your system does not get forgotten.

Common questions about ventilation servicing & maintenance in Auckland.
How often should a ventilation system be serviced?
Annual servicing is the standard recommendation for both positive pressure and balanced ventilation systems in New Zealand. If your system hasn’t been serviced in the last 12 months, that’s the starting point.
You can replace the filter on most systems yourself if you have the correct grade for your unit. What a filter change doesn't cover is the fan housing, ducting and diffusers. Organic growth accumulates behind the filter where it isn't visible, and ducting can work loose without any obvious sign at the vent. A professional service covers the full system, not just the filter.
Do you service all brands?
Yes. We service all makes and models of positive pressure, balanced and extractor systems. HRV, DVS, SmartVent, MoistureMaster, Sayr, Mitsubishi Lossnay, Zehnder, Lunos, Alnor, Stiebel Eltron and others.
Do you repair ventilation systems?
Yes, where a repair is needed. Every MiHT service uncovers your system's condition before any work starts and documents it again afterwards. If something needs attention beyond a standard clean, filter change, or airflow check, we tell you exactly what it is and coordinate the repair through a trusted external provider. We do not install new units and we do not carry out electrical repairs ourselves, but we make sure nothing found during a service gets left unresolved.
Does a MiHT service meet Healthy Homes Standards requirements for rental properties?
Yes. The Healthy Homes Standards require functioning ventilation in specific areas of rental properties. A MiHT service confirms your ventilation systems are operating correctly and provides a written condition report that can be kept on file for your records. If you manage multiple properties, a Care Plan schedules servicing automatically across your portfolio.
Is a professional service worth it if the system seems to be working?
Your ventilation system can appear to work while delivering significantly reduced performance. When a system isn’t delivering the required air changes per hour, CO₂ and other pollutants accumulate in occupied rooms even though the fan is running. A full service checks whether the unit is actually operating as it should.
What's the difference between a filter change and a full service?
A filter change addresses one component. A full service covers the entire system: fan units, housings, ducting, diffusers and intake areas. A filter change won't clear the organic growth that's built up behind the filter in the fan housing, and it won't identify ducting that's come loose or been damaged.
Why don't you install ventilation systems?
It's a deliberate choice. Companies that install systems have an interest in recommending new units. We don't. Our business only works if your existing system keeps performing, which means our advice is about getting the most from what you've already bought.
How much does a service cost and what are the Care Plans?
Pricing starts at $249 inc GST for positive pressure systems, $349 for balanced systems and $135 per unit for extractor fans. Final pricing is confirmed at booking based on your system and the number of units. You can book a one-off service or set up an Annual or Biennial Care Plan, which schedules the service automatically each year or every two years. No lock-in.
Do you service ventilation systems across all of Auckland?
Yes. We service positive pressure, balanced and extractor systems across Auckland. Your booking includes travel. No extra charges for location.
Turn a system that has been running unserviced into one that is documented, maintained, and performing the way it should.
