With 6,105 households in Cinco Ranch, most of them built out within a fairly tight window around the mid-to-late 1990s, we keep logic boards, drive gears, and start capacitors for that generation of chain and belt drive openers on the truck, because we see the same failures often enough to justify it. A $157,395 median household income here also means we see more owners replace an opener outright rather than keep nursing an old chain drive through one more repair, so we stock current belt-drive units too. What we don't carry on the truck is every proprietary board for newer smart-home-integrated openers - those sometimes need a manufacturer-specific part we have to order, and we'll tell you up front if that's the case rather than string out a visit.
