Because we're driving 13 miles to get to a Bellaire call and not restocking mid-job, the truck carries what the housing era actually calls for: drive gears and sprockets for chain and belt units from the 1990s-2010s window, replacement logic boards for the mid-range and higher-spec openers that fit a market with Bellaire's income profile, and the usual wear parts - trolley carriages, limit switches, wall control units. What we don't carry on every run is a part for an opener outside that common range - a very old chain-driven unit using hardware nobody's made in years, or an unusual commercial-grade unit. If your opener falls into either of those, we'll likely need to order the part rather than fix it same-visit, and we'll tell you that up front rather than guess on-site.
