Most of the housing stock in this part of the service area went up in the 1980s and 90s, and Catalina Foothills sits right in that band with a median build year around 1985. Doors from that era were sized and hung for lighter panel weight and simpler spring counterbalance than what's standard now, and a lot of those original openers were never rated for insulated steel replacements that got installed later. That mismatch is the single most common reason a homeowner here calls for a new install instead of a repair - the door was replaced at some point but the track, drum, or opener bracket underneath is still the 1985 part, and it's carrying more than it was built for.
Heat is the other driver. This is a severe-heat climate band, and repeated summers of that kind of temperature swing dry out lubrication and stress plastic idler bearings and nylon rollers faster than they'd wear in a milder climate. On a door that's already outliving its original hardware, that heat load is often what finally ends the setup rather than starts a new problem on its own.
