Ventilation FAQs
Why does ventilation with heat recovery pay off?
It exchanges stale indoor air for fresh outdoor air while keeping most of the heat inside — comfort and lower heating costs.
How loud is such a system?
Well-planned systems run quietly in normal operation. The acoustic planning of the ducts is decisive — that is exactly what we focus on.
How often do filters need changing?
Typically every 3–6 months depending on dust load. We show you how to change them or take over the task in a maintenance contract.
