Best Annual Service in Buffalo NY

Bill from Zenner & Ritter was wonderful! He came to our house and went above and beyond what we expected. He walked our entire house with us and went over changes we could easily make ourselves as well as how Zenner & Ritter could come in and help us. We are very very glad to have called Zenner & Ritter and would highly recommend them.

This company deserves a 10 Star if We could give it, we would! Love the way they follow up prior to having a Tech arrive, plus the picture of who is actually arriving that day. Todd was so professional and knowledgeable! Thank you everyone! When you call, their greeting is Awesome as well! Keep up the amazing job!

Efficient, quick and great work!
