Does Hp Matter On Garage Door Opener
The first is the size of your garage door. If you have a double-wide door or a door that is particularly large and heavy, you will need a opener with more HP. 1/2 HP is typically the minimum for a door opener, with 3/4 HP and 1 HP being common options as well.
The second consideration is how often you plan to use your garage door. If you expect to open and close it several times throughout the day, you will want a opener with a little more horsepower so that it can handle the additional wear and tear.
Finally, consider any special features that you want in a garage door opener. If you want an opener that includes a built-in security system or one that can be operated via your smartphone, you may need to look for a model with a little more horsepower.
In general, however, the average homeowner will be satisfied with a 1/2 HP opener for their garage door.
Horsepower Isnt The Most Important Factor

Horsepower gets our attention and the garage door opener manufacturers know it.
Most people dont really care about smartphone integration or extra safety features like automatic locking. I meantheyre nice innovations, but theyre not going to get me to run out and buy a new garage door opener.
Imagine youre walking through Lowes or Home Depot and you see a new garage door opened with 1 1/4 HP. Your old one has a measly 1/2 HP.
On some level, you start thinking that the bigger motor is going to work less or your garage door is going to open faster.
Then youre hooked.
YOU MUST HAVE IT!!!
But thats wrong.
That extra 3/4 HP doesnt open my garage door any faster and its not the motor that actually does most of the work.
One other thing that wont matter is whether or not you have a high-lift garage door. No matter if you have a standard track or high-lift track, that wont change how powerful a garage door opener you need.
So if garage door opener horsepower isnt that importantthen what is it good for?
