HRV & Dehumidification Maintenance Services

Like any mechanical system, they need regular servicing to keep performing properly.

Why Maintenance Matters
Why Your Ventilation System Needs Regular Servicing
Over time, filters become blocked, components collect dust, drains can become restricted, and system performance can gradually decline.
When an HRV or dehumidification system is not maintained, it may still appear to be running, but airflow, humidity control, indoor air quality, and energy efficiency can all be affected.
Regular servicing helps identify small issues early before they become bigger problems.
Signs Your System May Need Servicing
- Reduced airflow from vents
- Stale or stuffy indoor air
- Higher indoor humidity levels
- Condensation returning on windows or surfaces
- Musty smells or mould concerns
- Unusual fan noise or vibration
- System alerts or controller issues
- Filters due for replacement
A ventilation or dehumidification system is only effective when it is clean, balanced, and operating correctly. Preventative maintenance helps keep the system working as intended.

Common Questions
What Homeowners Ask Us
-
Portable dehumidifiers are effective in a single room, but they don't address the cause of moisture build-up (lack of fresh air exchange), and they need to be emptied manually. A ducted system distributes through every room and runs automatically.
-
Yes. Systems are routinely retrofitted into existing homes. We design duct runs to work with your ceiling and roof space, keeping building work to a minimum.
-
Most homeowners notice fresher air and less condensation within the first few days, with improvements continuing to stabilise over the following weeks.
-
Very little. The fans are low-wattage, and heat/energy recovery means the system typically reduces heating and cooling costs overall.
