“I couldn’t be happier with Ferkus! They are truly a great company and by far the best in the country. They always send reminders when it’s time to check my VMC, which makes everything so easy and stress-free. After each visit, I receive a detailed report with pictures, so I can clearly see the work that was done. Their team is responsive, polite, and very professional. They also show a lot of respect for the house — everything is left clean and tidy after the job. I’ve had awful experiences with other providers in the past, but Ferkus is on a completely different level. Highly recommended!”

“Simply the best company out there! Young team, motivated and competent, they explain the work they do and a team where customer satisfaction is a priority! My ventilation was cleaned and disinfected. Since the old system was broken, I received a quote on request the same day for a new Pluggit system with (according to my own wishes) an additional scenting system. I am thrilled and say a big thank you again to the whole team for the great price, best work and competent and very friendly professionals!”

Einfach beste Firma die es gibt! Junges Team, motiviert und kompetent, erklären die Arbeit die sie tun und ein Team wo Kundenzufriedenheit prioritär ist! Meine Ventilation wurde gereinigt und desinfiziert. Da die alte Anlage hinüber war bekam ich auf Anfrage am Tag selbst ein Kostenvoranschlag für eine neue Pluggit Anlage mit (nach eigenem Wunsch) einer zusätzlichen Beduftungsanlage. Ich bin begeistert und sage dem ganzen Team nochmal ein großes Danke für den super Preis, beste Arbeit und kompetente und sehr sympathische Fachkräfte!
