In the fall of 2016 we ordered a new French Door and 2 front bay windows from Centennial. We were "wowed" by their saleswoman who showed us how their technology is superior. There were also not a lot of negative reviews on line. We should have known better.
The installer that Centennial used is no longer working for the company (or so we are told). Both the front windows had major drafts, and the French Door actually had pieces missing from the install (thus, they said, explaining why the door leaked when there was any combination of rain and wind). They have been back to my house 3 times, and they still have not fixed the problem. There are currently puddles in my kitchen.
Their warranty is as good as the people who stand behind it. Getting through to the service department is almost impossible, and you are greeted by a voice message indicating that they will call you back in 24-48 hours (don't count on that). Contacting the website help desk can usually speed up the process, but then again...dont' count on it. They must be REALLY busy with repairs.
When managers call you they seem concerned, but they never follow up to see if you are happy.
We are now at the lawyer stage. I advise you find another company and save yourself the grief that we have experienced.
