We all like to have a high powered vehicle, with lots of horsepower. For every guy it is the same with every machine we get. Though we may not come across a 300HP garage door opener (atleast not yet!) Horsepower is important when considering a garage door opener.or HP is very basic information you need to know. The horsepower will assure that the garage door opener has enough power to lift your garage door. Therefore make sure you have checked your garage door, including height, weight, balance and type of garage door.
For most single and double car garage doors (up to 350 lbs), the 1/2 HP is adequate.
The 1/2-horsepower motor is the most common type for residential use. It will work on one or two door garages. For heavier garage doors such as carriage house or solid wood garage doors, the 3/4-HP is ideal choice. The 3/4-HP is for super-heavy garage door (up to 500 lbs), more power is better than not enough. Don’t make the mistake of buying a 1/2-HP opener and installing it only to find out that you need a stronger opener to open your garage door.
