Two things drive most of what breaks in Sun Lakes: the age of the stock and the heat. With a median build year of 1990, a lot of hardware here is original or close to it - springs rated for a lifetime of cycles that's long since been used up, openers that have outlived the warranty by twenty-plus years. Layer on a climate that sits in the severe end of the heat band, and you get nylon rollers that go brittle, lubricant that cooks off bearings faster than it would somewhere milder, and steel panels that expand and stick in their tracks on the worst afternoons. Median household income here runs $63,545, and what we see most often from owners at that level is a preference for fixing the spring or the opener rather than replacing the whole door - which is usually the right call unless the track or the panels themselves are the actual problem, not just the parts that move them.
