Indoor Air Quality

Your Air Ducts Could Be Making Your Family Sick

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.

Air Nova Duct Services uses HEPA-filtered negative pressure equipment and rotary brush systems to completely clean your duct system from the inside — removing years of accumulated contamination.

  • Reduce indoor allergens & dust
  • Improve HVAC efficiency & airflow
  • Eliminate musty odors from vents
  • Lower energy bills by up to 30%

Warning Signs

Does Your Home Need Air Duct Cleaning?

These are the most common signs your air ducts are overdue for a professional cleaning.

Visible Dust Around Vents

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.

Musty or Stale Odors

A musty smell when your HVAC system runs indicates mold or mildew growth inside the duct system. This needs immediate attention.

Worsening Allergies

If family members experience more sneezing, coughing, or allergy flare-ups indoors, contaminated ducts may be circulating irritants throughout your home.

Rising Energy Bills

Clogged ducts restrict airflow and make your HVAC system work harder, consuming significantly more energy to maintain your desired temperature.

FAQ

Air Duct Cleaning — Frequently Asked Questions

Common questions from homeowners in Palo Alto and throughout Los Angeles County.

How often should I get my air ducts cleaned?
The EPA recommends every 3–5 years for most homes. However, if you have pets, allergies, asthma, or recently completed a renovation, annual cleaning may be beneficial. Homes with visible mold or pest infestations in ducts should be cleaned immediately.
How do I know if my air ducts need cleaning?
Look for dust or debris around vent covers, musty odors when the HVAC runs, increased allergy or asthma symptoms indoors, dust settling quickly after cleaning, or visible mold inside vents. If you haven't had them cleaned in 5+ years, it's time.
How long does air duct cleaning take?
Most residential homes take 2–4 hours. Larger homes or heavily contaminated systems may take longer. We'll give you a time estimate after the initial inspection.
Is air duct cleaning worth it?
Yes. Clean ducts improve indoor air quality, reduce allergens, help your HVAC system run more efficiently, lower energy bills, and extend the life of your equipment. For homes with allergy sufferers or pets, the difference is noticeable immediately.
