If you’ve noticed dust piling up around your vents or experience frequent allergy or asthma flare-ups indoors, it could be due to dirty ductwork. Musty odors when your HVAC system is running or uneven airflow—like hot and cold spots in different rooms—are also common signs of buildup inside your ducts.

Recently completed construction or remodeling projects can introduce drywall dust, debris, and contaminants into your duct system. And if it’s been more than three years since your last cleaning, it’s a good time to schedule a professional service. Clean ducts lead to better air quality, improved HVAC performance, and peace of mind.
