How air moves through a central system

Air path: return duct, filter, air handler, supply ducts — one clogged filter drags the whole loop down.

Illustration, not to scale. The local workload: 3 heat or excessive-heat days and 28 winter-storm or freeze days in 2016–2025 — filters, coils and capacitors age faster under long cooling seasons. 13 lightning-damage reports within 10 miles and 249 damaging-wind reports over the same span.
