Looking to replace the windows in my home. Should I choose Lowe's to install them? First time using them to do home improvement.

No

I've only ever heard positive things about Lowe's

Yes you can get Lowes to put your windows they will do a good job

We used their contractors to install carpet for us a few years ago. It was a couple of young guys and they were pretty good and professional

I don't know about their installers, but I would still shop around with reputable contractors.
