size motor for garage door?

[line guy]

I have a 12x13 garage door in my pole barn and not sure how to size the right wall mount (jackshft) opener. It is insulated and has a row of windows. Local installer wants $1000+. I dont need all the extras like mobile, wifi, just remote and push button.

A 1 horse reversible motor should be more than adequate.

Any advice you take from me is guaranteed to be worth exactly what you have paid me for it.

Is it possible to find a used unit?

$1000 all inclusive installed isn't too bad. Figure you are paying full list for the opener and a few hours of time for travel and installation.

You can probably find an online deal and DIY for ~$450.

If the door is balanced it should only take 1/2hp opener.

There is a big difference between a commercial opener and a residential opener. It would help if you could give a model or other info. Is it a jackshaft opener? Is it a trolley opener? How many cycles an hour are you planning to use it? Is he replacing the hollow tube with a solid shaft? Too many variables to guess correctly. Plus there is a liability issue so all safety systems must be in place and those take time.

Thanks for all info. Getting more estimates right now. Light use 1 or 2 times a day hollow tube, jackshaft mount, lift master 8500

I just installed a Chamberlain B970, trolley type garage door opener. It is on a 8x10 garage door, fully insulated and stiffners on the panels. it is very quite with a great warranty. Lift force equivalent to 1 1/4 hp with battery back up, belt drive. It is for a much larger door than mine, but for the warranty, could not pass it up. I installed myself.
