At 7,283 households and a median income of $100,222, Manchester runs higher on income than the $80,694 median for the broader service area, and the newer housing stock reflects that: more double garages, more insulated steel doors versus bare aluminum, and more openers with safety sensors built in from the factory rather than retrofitted after the 1993 federal mandate. The area still sits in the same cold climate band as the rest of our coverage, which means winter cold-snaps are still the top cause of stiff springs and frozen track calls here, same as anywhere else we go. The difference is less in the weather and more in the door itself - a 30-year-old sectional door with factory safety sensors behaves, and fails, differently than a 60-year-old one-piece door on retrofit hardware a few miles away.
