Two things line up badly in Irvine, and together they explain most of the install calls. First, the climate band here is severe cold, which means winters put real stress on a garage door system - metal contracts, old seals crack, springs rated for milder climates fatigue faster. Second, a large share of the housing stock dates to right around 1959, near the start of the area's 1959-1988 building run, so a lot of doors are at or past the end of a normal service life with no insulation layer to begin with. Put a sixty-some-year-old uninsulated steel door through a run of hard winters and the failure isn't a surprise, it's just a matter of which part goes first - the seal, the panel, or the opener trying to compensate. That combination is why a new install request in Irvine usually isn't optional by the time the call comes in.
