Motor overhaul of Duco HRV units

With many Duco HRV units, the complete installation does not immediately need to be replaced. When mainly the motor, bearings or rotating parts show wear, overhaul is often a cost-effective and sustainable alternative.

Don't know which Duco HRV model you have?

Check the type plate of the HRV unit or send us a photo via WhatsApp. We are happy to help you determine which repair or overhaul is best suited.

Overhaul or replace?

Many Duco HRV units can last for years when the motor is overhauled. This is often more cost-effective and sustainable than replacing the complete installation.
