average life of a garage door opener
Estimates on longevity are based around usage, but most experts believe the average garage door should last between 15-30 years, depending on construction quality, maintenance and local climate conditions. Automatic garage door openers normally provide 10-15 years of reliable service. One of the most important components in a garage door assembly is the spring mechanism, which includes the torsion springs and tension springs. A standard garage door spring has a design life of 20,000 cycles while tension springs should last between 5,000 to 10,000 cycles. A cycle represents opening and closing the door one time. Obviously, the more the door is used, the sooner the springs will break down. Below you can see the life expectancy of a 10,000 cycle spring determined by daily use: 1  2 times daily = about 14 years.  4 times daily = about 7 years.
