Keep your indoor air clean, your home energy-efficient, and your MVHR unit running smoothly with expert servicing from Earthwise Construction.

We service all major MVHR systems and are a certified partner for Zehnder. We offer two types of MVHR servicing: ongoing maintenance plans for Zehnder units and one-off services for all other MVHR brands.

How often should you service your MVHR system?

• Every 6 months: Replace filters
• Every 12 months: Service to clean key components
• Every 4 years: Deeper clean including internal parts where accessible
• At 10 years: Ductwork should be cleaned using a specialist cleaning system

We tailor the service to your unit’s age, type, and access — helping you meet manufacturer guidance and maintain healthy airflow.

Zehnder MVHR Servicing Plans

For Zehnder MVHR owners, our two tailored service plans include regular maintenance and free filters delivered twice a year.

One-Off MVHR Servicing (All Brands)

We also provide one-off servicing for all other brands. This is ideal for systems outside warranty or where regular care is still essential.

What does a service include?

• Remove and clean all air valves, with access-based duct cleaning
• Remove and wash heat exchanger
• Clean fans, bypass flaps, and defrost pre-heater (where applicable)
• Internal cleaning of the MVHR unit
• Clean intake/exhaust grilles (if accessible)
• Change filters (if requested/set provided)
• Complete and leave a maintenance log
• Perform firmware update (Zehnder ComfoAir Q only)

⏱️ How long does it take?
Typically, 2 hours. We’ll need access to a bathroom or utility room to clean parts on-site.
