Common questions

How often should ventilation filters be changed?

It depends on the system and environment, but most benefit from filter changes every few months. We can set up a schedule so it's never forgotten.

What is MVHR?

Mechanical Ventilation with Heat Recovery supplies fresh air while recovering heat from outgoing air, efficient and common in modern, well-insulated buildings.
