Most homes should have ducts cleaned every 3–5 years, depending on dust levels, pets, allergies, and recent remodeling. Homes near busy roads or construction zones may need more frequent service.

We recommend an annual cleaning for most homes. Multi-unit properties and heavy-use laundry systems should be cleaned more frequently.

Excessive dust, reduced airflow, allergy triggers, musty odors, or recent construction are common indicators.

Long drying times, hot laundry rooms, burning smells, or lint buildup at the exterior vent usually mean the vent is restricted.

We clean supply lines, return lines, and main trunk lines using negative-air systems and professional agitation tools. This removes dust, debris, and contaminants at the source.
