Air Duct Cleaning
Ductwork moves every cubic foot of conditioned air through your home, which also means it moves dust, allergens, and biological growth if it isn’t inspected. We clean, sanitize, and repair ducts so your system isn’t fighting restricted airflow or recirculating contaminants.

What Air Duct Cleaning, Sanitizing & Sealing Involves
Air duct cleaning removes accumulated dust, debris, and in some cases rodent or insect activity from the supply and return runs using negative-pressure vacuum equipment, agitation tools, and a sealed collection system so debris doesn’t just get pushed further down the line.
Sanitizing addresses biological growth, mold or bacteria that can develop in ducts exposed to condensation or humidity, using an antimicrobial treatment applied after the physical cleaning. Sealing closes gaps and disconnected joints in the duct run itself, which is often the bigger factor in both air quality and energy loss, since a leaking duct pulls in attic or crawlspace air regardless of how clean the interior surfaces are.

Duct Repair and Replacement
How Our Air Duct Cleaning Process Works
1. Camera Inspection First
Before any cleaning begins, a technician scopes the duct system to identify actual debris buildup, disconnected sections, or biological growth, rather than cleaning on assumption.
2. Negative-Pressure Cleaning
A powerful vacuum is connected to the duct system while agitation tools loosen debris along the interior walls, pulling contaminants into a sealed collection unit instead of spreading them through the home.
3. Register and Return Vent Cleaning
Supply registers and return grilles are removed and cleaned individually, since these are often the most visibly dirty points in the system and the easiest for dust to reenter through.
4. Sanitizing Treatment (If Needed)
If inspection reveals mold, bacteria, or musty odor sources, an antimicrobial treatment is applied after cleaning to address biological growth rather than just visible dust.
5. Sealing and Final Airflow Check
Disconnected joints or gaps found during inspection are sealed, and airflow is tested at the registers to confirm the system is delivering conditioned air as designed.
How to Know Your System Needs Duct Cleaning
Not every home needs duct cleaning on a fixed schedule. These are the actual signals worth acting on.
Visible Dust Blowing from Registers
If you can see dust or debris exiting a supply register shortly after the system starts, that’s a sign of heavier accumulation than routine filter changes are catching.
Musty Odor When the System Runs
A musty smell that’s noticeable specifically when the AC or heat kicks on, rather than constantly present, often points to moisture or biological growth inside the duct system itself.
Recent Renovation or Pest Activity
Construction dust from a remodel, or evidence of rodents or insects in the attic near ductwork, are both direct reasons to schedule a cleaning rather than wait for a symptom to appear.
Uneven Airflow Between Rooms
If some rooms cool or heat noticeably slower than others, a duct inspection can reveal whether it’s a blockage, a disconnected section, or simply a design issue unrelated to cleanliness.
Duct Repair and Replacement Considerations
Cleaning addresses what’s inside the ductwork. Repair addresses the ductwork itself, torn flex duct, disconnected joints, crushed sections from foot traffic in an attic, or undersized runs that were never adequate for the connected system in the first place. Repair and replacement pricing ranges from $400 to $6,500 depending on how much of the system needs work and whether access is straightforward or requires more extensive attic or crawlspace work.
Sealing leaky ducts is one of the more overlooked factors in both indoor air quality and energy efficiency, since a duct pulling unconditioned attic air undermines the system’s efficiency regardless of how new or well-maintained the equipment itself is. Financing for larger duct projects is available on our financing page, current offers are on our specials page, and if a duct issue is affecting cooling during a breakdown, our emergency AC repair team can help in the meantime.

When to Schedule Duct Cleaning
After a Home Renovation
Construction and drywall dust settle into ductwork during remodeling work, even when vents are covered. A post-renovation cleaning clears this before it recirculates.
Moving Into an Older or New-to-You Home
An unknown duct history is reason enough for an inspection before settling in, especially in a home where the previous owner’s maintenance habits aren’t known.
After Confirmed Pest Activity
Rodents or insects in attic ductwork leave debris and odor that a standard filter change won’t resolve. This warrants inspection regardless of season.
When Household Allergy Symptoms Increase Indoors
If allergy or respiratory symptoms noticeably worsen at home compared to elsewhere, duct condition is one of several factors worth ruling out alongside filter type and household humidity.

How much does air duct cleaning cost?
Duct cleaning pricing depends on the number of vents, system accessibility, and whether sanitizing or repair is also needed. A technician provides an exact quote after the camera inspection.
How often should air ducts be cleaned?
There’s no fixed universal schedule. Homes without pets, recent renovations, or visible dust issues may go several years between cleanings, while homes with any of those factors benefit from more frequent inspection.
Does duct cleaning actually improve indoor air quality?
It can, particularly when there’s confirmed dust accumulation or biological growth inside the ducts. If air quality issues are unrelated to duct condition, such as household humidity or an aging filter, cleaning alone won’t resolve them.
What’s the difference between duct cleaning and duct sealing?
Cleaning removes debris and buildup from inside the ducts. Sealing closes physical gaps or disconnected joints in the ductwork itself, which affects both air quality and energy efficiency by preventing unconditioned air from entering the system.
Can dirty ducts affect my energy bill?
Restricted airflow from heavy debris buildup makes the system work harder to move the same volume of air, and leaking ducts force the system to condition extra outside air pulled in through gaps. Both increase energy use.
How long does a full duct cleaning take?
Most residential duct cleanings take two to four hours depending on the number of vents and duct runs, with additional time if sealing or minor repair is completed the same visit.
Will duct cleaning fix a moldy smell?
If the odor source is biological growth inside the ductwork, cleaning combined with an antimicrobial sanitizing treatment typically resolves it. If the source is elsewhere, such as the evaporator coil or condensate line, that’s addressed separately.
Is duct repair needed if the ducts are just dirty, not damaged?
No. Cleaning and repair are separate services. Repair is only needed when ducts are physically damaged, disconnected, or undersized, which is confirmed during the camera inspection.
Can leaky ductwork make one room hotter or colder than the rest of the house?
Yes. A disconnected or leaking duct run supplying a specific room is one of the most common causes of a single room performing worse than the rest of the house.
Do you clean dryer vents as well as HVAC ducts?
Dryer vent service is handled separately from HVAC duct cleaning due to different equipment and safety considerations. Ask during scheduling if you need both addressed.
