J’ai installé une pompe à chaleur Stiebel Eltron avec la société AFM SA et j’ai été très satisfait du travail réalisé. La société a parfaitement répondu à mes attentes. Je recommande vivement !

Bon renseignements, prise en charge rapide, ouvrier souriant pas de mauvaise surprise merci enormement.

Millius à été réactif, rien à redire sur leur intervention si ce n'est un grand merci. Ils nous ont aussi fait un devis pour la remise en état. Efficace et correct, à recommander.
