How often should air ducts be cleaned?”


Whether you live in Washington DC, Maryland, or Northern Virginia, your HVAC system plays a huge role in your home’s air quality, energy efficiency, and overall comfort.

But dust, debris, allergens, and contaminants build up inside the ductwork over time — and cleaning them regularly is essential.


Here’s exactly how often your air ducts should be cleaned and why it matters.




⭐

Recommended Air Duct Cleaning Frequency



According to HVAC professionals and indoor air quality experts:



✔ Air ducts should be cleaned every 3–5 years.



This is the standard recommendation for most homes.

However, many DC Metro residents may need it more often due to:


  • Urban pollution

  • Older HVAC systems

  • High humidity

  • Heavy traffic/pet dander

  • Renovations & construction dust

  • Seasonal pollen (MD & VA)



So depending on your home and lifestyle, you may need cleaning every 2–3 years instead of every 5.




🔍

Signs You Need Air Duct Cleaning Sooner



If you notice any of these signs, your air ducts likely need cleaning NOW:


  • Dust blowing out of vents

  • Visible dust buildup on vent covers

  • Musty or dirty odors when HVAC runs

  • Uneven airflow in rooms

  • Increased allergies or respiratory issues

  • HVAC filters clog faster than normal

  • You recently renovated your home

  • You moved into an older house

  • You have multiple pets



These issues are VERY common in DC row homes and Maryland/Virginia single-family homes.




🏡

How Often Should DC, MD & VA Homes Be Cleaned?




Washington DC (NW, NE, SE, SW)



Older buildings + humidity + city pollution =

➡️ Every 2–3 years



Maryland (PG, Charles, Montgomery, Anne Arundel)



Higher pollen + suburban dust + pets =

➡️ Every 3 years



Northern Virginia (Arlington, Fairfax, Alexandria)



Newer systems but high pollen =

➡️ Every 3–4 years


If you have pets, allergies, or a large household, shorten these by 1 year.
