Duka Ventilation
Experts in fresh air and healthy indoor climates
Duka Ventilation is among the leading experts in Denmark when it comes to creating healthy and fresh indoor climates in private homes. For decades, they have delivered technical ventilation solutions that ensure optimal air exchange and remove moisture and particles from the home.
However, technical products often bring a large volume of questions from curious and quality conscious customers. Exactly how does the system work? Which filter fits my specific model? And which solution is right for my particular house? To ensure these questions are always answered quickly and accurately, Duka Ventilation chose to implement Karla as a digital assistant on their website.
Over 7,900 messages handled with AI
Since implementation, the results have been significant. In the first 4 months of 2026, Karla has already handled 7,903 messages across 1,729 unique conversations. This means that a large portion of routine inquiries are now resolved immediately, whether the customer seeks help on a Monday morning or a Sunday evening.
This has freed up valuable time for Duka's service department, allowing them to focus their efforts on more complex technical cases that require human assessment
"From the start, the people behind Karla have had our needs in focus. In a good and pleasant way, we have worked together to create a solution that assists our service department in a proper and effective manner. We are positively surprised by what it is able to help with."

Data as a driver for a better website
One of the most valuable benefits of the collaboration has been access to Karla's Insights. Through the solution, Duka Ventilation now gains a unique insight into what their customers are actually asking about and what they find confusing in real time. This dataset is actively used to optimize and improve the content on the website itself.
By understanding user knowledge gaps, Duka can continuously adjust their texts, guides, and product descriptions to stay one step ahead of customer needs. The collaboration has demonstrated how AI functions not just as a customer service channel, but as a strategic tool for business development and content optimization. At Karla, we are proud to support Duka Ventilation on their digital journey to create even better experiences for their customers.
