Spring cycle calculation limits
On a 1986-era door, springs are also just old. Torsion springs are rated for a number of cycles, and a door original to a house built that year has had close to forty years to use them up, even with light use. Mountainaire is a smaller area - something like 494 households - so we're not pulling from a deep well of recent service history here the way we might in a denser part of the service area.
