How does home ventilation work?

Home ventilation systems work by pushing out hot or stale air and drawing in cooler, fresher air from outside. This can happen passively through vents or actively with systems like whole house fans, attic exhaust fans, or swamp coolers. These systems create airflow that reduces heat buildup, prevents mold and moisture issues, and boosts indoor air quality. At Done, we design and install ventilation solutions tailored to the needs of Colorado homes.
