Signs Your St. Louis Home Needs Air Duct Cleaning
St. Louis’s humid summers and high seasonal allergens mean ducts get dirty faster. Watch for these warning signs:
Visible dust when HVAC runs is a clear sign cleaning is overdue.
If indoor allergies are worse than outdoors, dirty ducts are likely the cause.
Stale smells indicate mold or bacteria growing in your ductwork.
Clogged ducts force your HVAC to work harder, increasing costs by 20-30%.
Always clean ducts in a previously-owned home — you don’t know their history.
The EPA recommends cleaning every 3-5 years under normal conditions.

Frequently Asked Questions About Air Duct Cleaning in St. Louis
Get answers to the most common questions St. Louis homeowners ask before booking their air duct cleaning service.
How much does air duct cleaning cost in St. Louis?
Residential air duct cleaning in St. Louis typically ranges from $299 to $499 for a standard home, depending on square footage and number of vents. We offer free in-home estimates so you always know your exact price before we begin. There are never any hidden fees.
How often should I have my air ducts cleaned?
The EPA and NADCA recommend cleaning every 3 to 5 years under normal conditions. However, St. Louis homeowners with pets, allergies, or young children benefit from cleaning every 2 to 3 years. You should also clean ducts after any major renovation or if you have recently moved into a previously owned home.
Does air duct cleaning really make a difference?
Yes, when done professionally with HEPA equipment. Dirty ducts circulate dust, pet dander, mold spores, and bacteria throughout your home every time the HVAC runs. Our customers consistently report fewer allergy symptoms, fresher air, and reduced dust buildup on surfaces after a thorough cleaning.
How long does air duct cleaning take?
A typical residential job takes 2 to 4 hours depending on the size of your home and number of vents. Commercial properties may take 4 to 8 hours. We work efficiently without cutting corners, and we never leave your home without completing a thorough post-cleaning walkthrough.
Is AL Air Duct Cleaning licensed and insured in Missouri?
Yes. AL Air Duct Cleaning is fully licensed, bonded, and insured in the state of Missouri. All technicians are background-checked and trained to NADCA standards. We have been serving St. Louis homeowners and businesses since 2019.
