HVAC solutions for DIY and professional installation
For ZET I built a website where homeowners, DIY enthusiasts and professionals can each find a clear path to a service, the online store or a quote.
4.9/5 on Google26 reviewsThree audiences, one brand, no confusion
ZET is an HVAC specialist based in Diepenbeek with more than 45 years of experience in installation and maintenance. The company sells and installs air conditioning, heating, plumbing and ventilation systems for renovations and new construction. It serves homeowners, DIY enthusiasts and professionals. Self-installers can find complete kits in the online store at zet-shop.be and get specialist advice in the Diepenbeek showroom.
Each audience arrives with a different question. The site needed to direct everyone to the right destination within two clicks: a service, the online store or a quote.
“Someone looking for a heat pump is not necessarily looking for self-installation instructions, and vice versa.”
A clear path for every service and audience
Technology helps people choose. It doesn’t try to take center stage.
- 01
Find the right service quickly
Air conditioning, heating, plumbing, ventilation, installation and maintenance each have a page with information tailored to the audience.
- 02
A dedicated path for self-installers
The self-installation guidance links clearly to the online store at zet-shop.be, so visitors immediately know where to go.
- 03
Share incentive updates quickly
SvelteKit and Storyblok let the ZET team publish news, promotions and incentive information themselves, which matters in a market that changes monthly.

No invented success percentages. The reporting combines consistent PageSpeed measurements with final Search Console data and compares like-for-like periods.
