Most of the housing stock across this service area went up between 1945 and 1988, with the median build year sitting around 1972, and the bulk of it across the eleven communities we cover is 1960s and 70s construction. Openers from that era, or replacements installed to match that era's hardware, were built for lighter doors and simpler track geometry than what's common now.
That matters here specifically because the climate band for this area is classified as cold and severe. A garage attached to a house built in 1968 usually wasn't insulated with the door cavity in mind, so the opener's gear housing, logic board, and sensor wiring sit through the same temperature swings as the outside air. Grease stiffens, plastic gears get brittle, and contacts on the wall control corrode faster than they would in a heated space.
Put those two things together - older mechanical setups plus genuinely cold winters - and you get a service area where opener failures cluster around first hard frost and again in late winter thaw-refreeze cycles, not evenly through the year.
