A guaranteed air handling system

ETT energy recovery air handling systems are contractually guaranteed for one year in France and abroad. In mainland France, the warranty covers parts, labour and travel.

Minimum 12-month warranty

In mainland France, ETT machines are guaranteed for between 1 and 5 years, depending on the type of machine.

All ETT machines in the ULTIMA range come with a 5-year parts, labour and travel warranty, excluding consumables (in mainland France).

You can also take out a full or partial extended warranty, up to a maximum of 7 years for your ETT air conditioning, heating and ventilation system.

A team of specialists, made up of Technical Coordinators, handles warranty claims. The coordinators support and advise our customers throughout the commissioning and warranty period of their installation. They are able to analyse and diagnose technical issues.
