A century of slow growth followed by a construction boom
Holly Springs stayed small for generations after its 1877 incorporation — about 300 people by 1880 — before recent decades brought rapid subdivision growth, so the town now has an unusually sharp contrast between its oldest homes near the original crossroads and its newest construction.
HVAC sizing across Holly Springs' old-to-new construction gap
Older homes near Holly Springs' historic crossroads typically need ductwork retrofits and different load calculations than the newer, tighter-built subdivisions surrounding them, so system sizing should be based on the specific home's construction era, not the town's overall growth story.

Energy-code baseline for Holly Springs' older homes
North Carolina's energy code sets duct-sealing and insulation standards that many of Holly Springs' oldest homes, built long before the code existed, don't currently meet; confirm what's required for a full system replacement on an older property.
