An opener that is too weak for your door strains itself, and one that is oversized wastes money. We size it correctly the first time.
Installing a new opener is straightforward in principle, mount the unit, connect the rail, and wire it up, but getting the setup right depends on matching the opener's lifting capacity to your specific door and correctly setting its force and travel limits. Skipping this step is one of the most common reasons a new opener wears out early or fails a safety reversal test.
We size the opener based on your door's weight, material, and whether it is insulated, since an insulated steel door needs considerably more lifting force than a lightweight aluminum one. Installing an opener that is undersized for the door forces the motor to work harder on every cycle, which shortens its lifespan considerably.
Once the opener is mounted, we set the travel limits so the door fully opens and closes without straining against the track at either end, and we calibrate the force sensitivity so the door reverses appropriately if it meets resistance. This force setting is a genuine safety feature, not just a comfort setting, and we test it directly rather than leaving it at a factory default.
Safety sensors are aligned and tested as part of every opener installation, since a door that will not reverse when something is in its path is a real hazard, particularly in households with children or pets.
It depends on your door's weight, which varies with material and whether it is insulated. We assess this directly rather than guessing based on door size alone.
Force limits control how much resistance the opener will push against before reversing. Set correctly, the door will stop and reverse if it meets an obstruction, which is an important safety feature.
In most cases yes, as long as the door's track and hardware are in good working condition. We check this during the initial assessment before installation.
