Breathe cleaner air. Roofsky Air Duct Cleaning Service removes dust, allergens, mold spores, and debris from your air duct system — improving indoor air quality and HVAC efficiency throughout San Mateo County.
Indoor Air Quality
The EPA estimates indoor air can be 2–5 times more polluted than outdoor air. Your HVAC system circulates air through your home 5–7 times per day — and if your ducts are dirty, it's recirculating dust, allergens, mold spores, and pet dander every single time.
Roofsky Air Duct Cleaning Service uses HEPA-filtered negative pressure equipment and rotary brush systems to completely clean your duct system from the inside — removing years of accumulated contamination.
Warning Signs
These are the most common signs your air ducts are overdue for a professional cleaning.
Dust or debris buildup around your vent grilles, or dark rings forming on the ceiling near vents, is a clear sign of contamination inside the ducts.
A musty smell when your HVAC system runs indicates mold or mildew growth inside the duct system. This needs immediate attention.
If family members experience more sneezing, coughing, or allergy flare-ups indoors, contaminated ducts may be circulating irritants throughout your home.
Clogged ducts restrict airflow and make your HVAC system work harder, consuming significantly more energy to maintain your desired temperature.
