Southlake built its housing in the growth decades and built it large: planned subdivisions of big-footprint houses, most with two systems and many with three, zoned ductwork serving wings that live different lives at different hours. The mechanical consequence is arithmetic. More systems per roof means more starters, more boards, more charges to drift, and a failure somewhere in the count most summers.

The calls follow the count. A zone that will not answer its thermostat while the rest of the house holds. A far wing losing ground every evening because its system has been cooling at partial strength since June. Zoned dampers and their controls aging into their second decade alongside the equipment they serve. West-facing glass in the big plans gains heat faster than a milder sizing assumed, and August collects that debt every year in the same rooms.

Winter asks the multi-system house its own question: which of its systems carries the sleeping wing on a norther night, and has that one been resting since spring. The 2021 freeze graded every multi-system house in the corridor at once, and the ones that held were the ones whose weakest link had already been found.
