The usual lifespan of a garage door opener is 10 to 15 years, but with proper maintenance of the rollers and springs, you may get 20 years or more out of it. Even if yours is still operational, there are compelling reasons to consider replacing it. Newer versions provide enhanced safety, security, and convenience, which may be reason enough to purchase a new garage door opener. For example, if your garage door opener lacks a safety reversing feature, or if the one it has no longer works, replacing the opener is strongly advised as a precautionary step.
