Describe use instead of guessing lifespan
Tell the technician whether the garage is mainly for occasional parking or is the household’s usual entrance. Several people using the opening can change the number of daily cycles. An estimate of your use is planning information; it is not proof of how many cycles the existing spring has completed.
Keep compatibility first
DASMA explains that spring life is affected by installation, condition and use, and that spring cycle life is not the same as the life of the complete door. A higher rating does not excuse the wrong spring selection for the assembly. Ask how the proposed replacement suits the door.
Compare the written terms
Request the part description, applicable warranty and maintenance guidance alongside any cycle figure. Avoid treating a quoted number as a prediction of an exact failure date. Repairs and spring adjustments belong with a trained technician because the system is under significant tension.
Your questions
Does twice the cycle rating mean exactly twice as many years?
No. Actual use and conditions prevent that simple calendar promise.
Can I choose a spring by its color or length alone?
No. Correct selection requires the relevant door and spring specifications.
