How about contacting them directly and asking for references?

I did that. I've called a few companies that have worked with these in the
past. Unfortunately, I received mixed comments on the installation
process.

Consistently, everyone likes the result. But I've had time quotes varied
from 8 hours to 20-30 hours. That's a little worrisome to me.

I was hoping to get a wider field of commentary here.
