Warranty promise
No repair.
No waiting.
For five full years from purchase, every NEXON product is covered by a full replacement warranty. If something goes wrong, we don't repair — we ship a new unit, fast.

FAQ
Frequently asked.
Is the warranty transferable?+
Yes — the warranty follows the serial number, not the original buyer. Useful for new homeowners moving into a property with a NEXON system installed.
Do I need to return the faulty unit before a replacement ships?+
No. For approved warranty claims we ship the replacement first and collect the faulty unit afterward, to minimize site downtime.
Is installer labor covered?+
Replacement unit shipping is fully covered. Labor for swap-out is reimbursed at standard regional rates for certified NEXON installers.
What happens after 5 years?+
The full replacement warranty period ends at 5 years. Extended service contracts are available through your NEXON distributor.
How do I register?+
Installers register through the partner portal. End customers can register their serial number via the contact form within 60 days of install.
