Hello,

I need to replace my old wooden garage door with a steel insulated door. I also need a new opener to go with it. The sales rep is trying to sell me a Liftmaster with 3/4 HP. The door is only 7x8.

With that much power I would expect it might open too fast and possibly do damage when it stops. My thought is that a 1/2 HP is more than adequate. LIFTMASTER is having a promotion on the 3/4 HP unit for almost the same price as a 1/2 HP.

Anyone have any experience with a much more powerful opener than required?

Thank you.
