Sunier AG Sanitär + Heizung — Mühlestrasse 9, 8344 Bäretswil, Switzerland

I contacted Mr. Sunier via email regarding information about a former business area of Sunier AG. Mr. Sunier responded immediately the following day. He was absolutely competent, helpful, and offered no added value, as the services were provided. Outstanding correspondence and suggests a serious and conscientious company philosophy, and thus also high quality. Thank you again, and keep up the good work! Stay healthy.

Sunier AG has been handling all plumbing and heating work in my 9-unit apartment building for years. Their last major project was replacing the entire heating system. The process went like this: Sunier AG provided a consultation, scheduled the work, ordered the system, delivered it, and installed it. I give them 5 stars. Completely satisfied!

Sunier installed a geothermal heat pump, a new boiler, and underfloor heating in our detached house. Both the service and the value for money were excellent. The staff were very friendly.

I have rarely received such top-notch service from a tradesman, from start to finish. Many thanks to Mr. Jörg Fischer. I can wholeheartedly recommend this company to everyone. R. Glauser
