The trouble spot in a town like Cowpens is parts availability for the oldest openers. A chain-drive unit installed when a house went up in the early-to-mid 1970s may use a motor or control board that's been out of production for years. We can source a lot of it, but not everything, and if a part's on backorder, that's a wait we can't shrink by driving faster.
The other place this goes sideways: someone assumes the opener is the problem when the door itself - spring, track, or roller - is what's actually failing, and the opener motor is just straining against a door that's hard to lift by hand. If your opener struggles or reverses on its own, lift the door manually first. If it's heavy or won't stay up, that's a door problem, not an opener problem, and fixing the opener alone won't solve it.
