So you have finally decided on getting an automatic garage door opener. After being bombarded with so many garage door openers and options, you ask yourself what exactly should be the size of the opener that you should be using. Allow us to thoroughly answer this question for you as we give you case-to-case basis of which options to consider.
Know Your Garage Door
The first thing that you should be considering is the material by which your door is made. If your door is made of steel, then it should be composed of a three layer steel-insulator-steel component. The insulator is a standard for countries which have varying weather for better heat release and retention. If your door is made of wood, then constant changes in weather can make it retain moisture, thus adding to its mass over time. Take down notes on how heavy or light your door can be as this is a crucial information for the next step.
Make sure that you put in mind the actual size of your garage door. Is it just a sectional door or is it large enough to make it a little harder to lift all by yourself? The door size can also affect the overall mass so we also need to know this information.
First Step: Considering The HP Size
Garage door opener sizes are chiefly translated into HP ratings. The higher the HP, the heavier it can accommodate. For steel garage doors, a 1/2HP motor can lift them as they are within the medium-tier group in terms of mass. However, if your garage door is so much larger than the typical ones, a 3/4HP would be needed. Measure your garage door size and compare this to the product specs of the opener that you are inspecting.
If your door is made of wood, then your opener must be able to adjust to the mass changes due to water retention over time. A 3/4HP motor can compensate for these adjustments that are inevitably to be made later on.
More often than not a 1/2HP motor is the ones that suits best on most doors. After all, you wouldn’t want to pay for the capital cost and operating cost due to electrical bills on an HP rating which you would neither need nor use at the end of the day.
Second Step: Considering The Type
The next thing that you should consider is the type of the garage door opener. There are three common types: Chain, Screw and Rubber Belt. These three are arranged in decreasing overall strength as well as noise output. A chain type is the strongest and most durable yet it produces the most noise while the rubber belt, while producing an optimal strength can be really quiet compared to the other two. However there are certain technologies right now that focuses on enhancing the inherent disadvantages of these types. There are chain types that are less noisier than most models while there are belt driven openers developed nowadays that are as strong and durable as chain-driven panels. Read the corresponding reviews of these models to know what suits you best.
Usually, a steel garage door can be driven efficiently by a belt driver while those that are extremely heavy require chain types. A balance between the two would be a screw type. A door made of wood can be driven by a chain drive or a screw drive due to its weight.
So there you are. In order to pick the most suitable garage door opener size, you must really get acquainted with your door specs in terms of material, size and mass. Carefully review these factors and take them into consideration in reading out the specs of your prospect opener. We hope that we have helped you pick out the best size for your garage door opener through this post.
