I original called Metro to repair a broken cable. While the repairman was at my house I arranged for two new garage doors to be replaced as well as one new opener. I ordered one 8 foot and one 16 foot door. I also asked that the opener for my existing 16 foot door be relocated to the new 8 foot door, keeping the new opener on the 16 foot, most used door.
The doors and opener were ordered and a crew came out to remove and install. After the installation, I noticed the new opener was much louder than the opener I had relocated. I was told by the installers that my existing door opener has a DC motor and is belt driven making it much quieter.
I wish the original sales person had noticed that and informed me of options for the new opener or at least told me of the upcoming situation before I made the decision to move the existing opener to the 8 foot door.

With all that said, the installers were very, very experienced, professional and did a great job of installation. I told my neighbor to ask for them when they have their doors replaced.
