What Causes It Around Here
Most of the houses we get called to in Pueblo West went up around 1999 - a different build era than much of Pueblo proper, where a lot of the stock dates to the 1960s and 70s. That matters for openers because it usually means the unit on your ceiling right now is the original one, installed when the house was framed, not a replacement from some later remodel. An opener that old is coming up on the end of its working life even if it still runs most days.
The second factor is the climate band this area sits in, which is classified cold-severe. That kind of cold is hard on an opener's circuit board, its gear set, and especially its drive belt or chain if the lubricant inside has thickened up over two decades of winters. A unit that struggles to pull a cold, stiff door on a January morning isn't broken so much as worn down by repeated cold starts over many years. Put the two together - original equipment plus two-plus decades of hard winters - and the opener is usually the weak link before the door itself ever has a problem.
