They may be out of sight and out of mind, but air ducts are essential to your HVAC system. Air duct cleaning can help extend the lifespan of your HVAC unit and keep your home safe from harmful airborne contaminants and further damage. Learn about the many benefits of air duct cleaning and why hiring a professional for the job is best. 

What Is Air Duct Cleaning?

9 tools needed to clean air ducts, including microfiber cloth, power drill, and air compressor

Air duct cleaning is the process of removing dust, debris, and other contaminants from the ducting that moves air through your heating, ventilation, and air conditioning (HVAC) system. Your local air duct cleaner will use tools like vacuums and brushes to dislodge and remove unwanted debris from your air ducts, which helps improve air quality and the efficiency of your HVAC.

Here’s what you can expect when you hire a duct cleaning pro. 

1. Improves Air Quality 

Whether you spend 24/7 inside your home or are always on the go, high air quality is essential to comfortable living. This is especially true if you or your loved ones suffer from respiratory issues such as asthma or other breathing conditions. Air duct cleaning can help remove airborne irritants so that excess dust, pollen, or mold spores don’t enter your lungs. 

2. Extends Life Span of HVAC

Your heating and air conditioning system is likely essential to your everyday. The more care you put into maintaining it, the better it runs. Cleaning out blockages from dust and gunk in your ducts means your system doesn’t have to work as hard to provide airflow, which is less taxing to the system over time. 

Plus, your local air duct cleaning professional can identify issues like leaks or damage to ensure maximum efficiency and a longer lifespan of your HVAC, saving you money in the long run. An efficient system means lower energy bills, too. 

3. Eliminates Odors 

Since you can’t see the buildup that’s accumulated in your ductwork over time, it’s hard to determine if musty or stale odors are caused by your air ducts or something else. The good news is a fresh cleaning can remove lingering smells from pets, cooking, or smoking that you could be unaware of. 

Your cleaner may also identify mold or mildew in your ducts. Not only does it cause a smell, but it can also damage your HVAC system, so it’s best to stay on top of mold remediation

4. Cleaner Space

The less dust and debris blowing through your air ducts, the fewer contaminants can settle onto your kitchen countertops, cabinets, furniture, ceiling fans, and flooring. Having your air ducts cleaned regularly can reduce or eliminate the amount of airborne debris in other areas of your home.

Although nothing can quite replace air duct cleaning, especially after a dusty home renovation or pest infestation, there are other HVAC maintenance practices you can do regularly to keep your air clean from debris and dust. 

  • Change out air filters 

  • Use a portable air purifier or install a whole-house air purifier 

  • Keep vents and registers clean 

  • Dust and vacuum regularly 

  • Use a dehumidifier to control and reduce humidity 

How Much Does It Cost to Clean Air Ducts? 

The cost to clean air ducts ranges from $150 to $800 depending on the type of air ducts you have, how many vents are in your home, and where you live. It’s about $0.15 to $0.30 per square foot to clean air ducts, so if you know the square footage of your home, you can calculate the cost for a general idea. 

Is Air Duct Cleaning Right for You?

The older the home and the older the HVAC unit, the more likely you’ll benefit from air duct cleaning to ensure you stay comfortable in extreme weather conditions and breathe air that’s free of dust and other contaminants. Homes with pets or that have undergone recent renovations need more regular cleaning, as pet dander and dust can accumulate over time. However, if your system shows no signs of mold, mildew, foul smells, or frequent dust, you likely don’t need supplemental cleaning outside of regular maintenance.

Frequently Asked Questions

Signs that you need your air ducts cleaned include a musty or stale smell when your HVAC is running, signs of mold or mildew near vents, higher energy bills with no major changes, dust on your vents, or an increase of pests in your home.

The key drawback of air duct cleaning is that it’s often a temporary solution to a larger problem like damaged or worn-out ductwork. Also, DIYing this project or hiring an inexperienced pro could damage your ducts, especially if they’re flexible.
