Written report, every visitBefore-and-after photos included, so you know exactly what was done.
Transparent, fixed pricingSee exact pricing upfront, before you book, with no surprises on the day.

Every visit covers more than the filter

FilterReplaced with the correct grade for your system, the part most owners think is the whole job.
Fan unitOpened, vacuumed and sanitised. Dust and growth here throws the fan off balance and cuts airflow.
DuctingChecked full-length for disconnections, restrictions and damage.
DiffusersEvery ceiling diffuser cleaned. One blocked outlet drags down the whole system.
Roof cavity intakeChecked for dust, moisture and pest activity where your system draws its air from.
Airflow checkVerified at every vent once everything's back in place, with results in your report.

We only service ventilation systems, we don't sell or install new units, so there's no upsell agenda. Every visit ends with a written report and before-and-after photos, so you know exactly what was done.

One visit. Filter replaced, fan, ducting and diffusers checked. A written report you can keep.

Common questions about HRV filter replacement in Auckland.

What's the difference between a filter replacement and a full service?

+

Not much. We build those checks into every filter replacement now. Your visit already covers the fan unit, ducting, diffusers and intake area, not just the filter itself. A full service becomes a separate job only if we find something that needs hands-on repair on site, like a fan rebalance or a duct reseal, and we'd quote that separately rather than bundle it into a standard visit.

Will I need to be home during the service?

+

Yes. Your ceiling space needs to be accessed for the unit and ducting inspection, and every room needs to be checked for diffuser airflow. Someone needs to be home for the duration of the visit.

How much does HRV filter replacement cost in Auckland?

+

It depends on your system generation and size. A Pre-2022 HRV filter replacement runs $249 to $390 inc GST, and a Post-2022 Classic Pro or AirSense system, which needs a genuine filter and a Filter Key reset, runs $339 to $620 inc GST. See the exact price for your system in the pricing table above. That price covers more than a filter swap: fan unit clean, full ducting inspection, diffuser clean in every room, an airflow check, and a written report with before-and-after photos.

Do you use genuine HRV filters?

+

We fit the correct filter for your system generation every time. Classic Pro and AirSense systems currently have no compatible aftermarket option, so those get a genuine HRV filter and Filter Key reset. Older Pre-2022 systems take a quality compatible filter matched to the correct grade for your fan box. Either way, you get the grade your system actually needs, not whatever's cheapest, and it's confirmed in your written report.

How often should I replace my HRV filter?

+

Most homes are fine on an 18 to 24 month interval, in line with HRV's own service guidance. If you've got pets, allergies, a dusty section, or you've just renovated, 8 to 12 months is more realistic.
