HEPA filters?
Better filtration going forward — still need interior clean if already dirty.
Dirty Filter vs Needing a Deep Clean
Filters protect the coil — they don’t clean what’s already growing inside.
A new filter stops new dust only. Odor, mold, and weak airflow usually mean the coil and blower need professional cleaning.
Filter maintenance
Wash or replace every 2–4 weeks in peak season.
When filter isn’t enough
Smell persists, visible coil mold, or dust still blowing — book deep clean.
