Well every comment here is close. I currently fix and install garage doors and openers.

If it's Styrofoam insulation then you are probably fine but if it's actual wall insulation then it's probably going to be an issue. Every bit of weight counts but it's ok to add extra tension to springs if a bit of extra weight is added. If you remove weight then they have to come back and remove the extra tension anyway.

If you can manually lift the door without much struggle then it will probably take 5-10 years before the opener breaks it's sprocket or grind the gears away. If the opener is 15 years or older then just leave it since that's when they start having issues anyway. Good springs last 6-8 years.

If I can ask, do you have any recommendations on styrofoam vs those reflective air gap insulation options on garage doors? I live in North Texas and have been contemplating adding some form of cheapish DIY insulation to my garage as it can get very chilly in the winter. Appreciate any advice a professional can offer.

Hollow steel door? I would imagine Styrofoam is best. I have seen what I think is the reflective stuff but I can't imagine it making that much of a difference with how thin it is.
