Frequently asked questions

Answers to the most common questions.

What is the difference vs. a full installation?+
In a full installation our technicians mount everything. With the DIY package you (or your tradesperson) mount, saving 40% on average in labour. Engineering, materials package and commissioning stay with us.
Do I need professional skills?+
For the HRV unit itself no, just mount it per our drawing. For the ductwork it helps to have a plumber or installer you know follow our layout plan.
What does a DIY package cost on average?+
Between € 4,000 and € 7,000 incl. materials + adviser + commissioning, depending on brand + home size. Fixed price after on-site intake. We deduct the ISDE subsidy of € 400 per unit.
What if I get stuck during installation?+
Call or WhatsApp us, we help by phone. In exceptional cases we send a technician (actual time only).
Do you work with contractors and HOA managers?+
Yes, this is well suited for project construction. For large projects we offer a tailored rate. Call us for a quote.
