Does Air Duct Cleaning Defeat a Dusty Home?

February 19, 2014

Here’s a question we hear often from Kansas City homeowners, “My home is constantly building up with dust! Will professional air duct cleaning help?”

It’s hard to say without actually seeing your air ducts. Several other things could be causing your home to build up with dust, including:

  • Dirty air filter
  • Dust buildup on the supply vents
  • Vacuum cleaners that kick up dust when you use them

But if your air ducts are clogged with excessive amounts of dust and debris, then yes, air duct cleaning helps, according to the Environmental Protection Agency (EPA).  
However, a dust build up in the duct is a symptom of a much larger problem... 

Fight the source, not the symptom

Time alone can’t cause that much dust buildup in your ducts.

Cleaning the air ducts without addressing the source(s) is like trying to get water out of canoe without addressing the leak first!
Speaking of leaks, the biggest cause of excessive dust in ducts is leaks and holes in the ducts. That’s especially true for ducts in your attic or crawl space. These leaks will suck in dust like nobodies business and push it through your vents into your home.
Before getting your ducts cleaned, have a professional contractor examine your ducts and seal them if there are any leaks or holes.
If you don’t seal the leaks, dust will build up in your ducts right after having them cleaned.

How to find the best air duct cleaner in the Kansas City area

OK, down to brass tacks. If your ducts need cleaning, make sure you find a good cleaner. Make sure they follow standards set by National Air Duct Cleaners Association (NADCA).  

Yes, there’s an association for everything nowadays!
The NADCA has several resources for homeowners, including Duct cleaning FAQs.

Whoever you hire, make sure they don’t  want to spray chemical biocides inside your ducts. The EPA warns that this can hurt more than help because it aggravates respiratory symptoms of asthma and allergy sufferers. 
The air sweep method is much safer. It’s a compressed-air hose connected to a truck-mounted vacuum system. The hose is fed into your ducts and carries away the dust and debris in your ducts. 
For more information about duct cleaning, read the EPA’s article, “Should You Have the Air Ducts in Your Home Cleaned?”

How much does air duct sealing cost?

Like we mentioned before, air duct cleaning will only be effective in the long run if you plug the leaks. Santa Fe can seal your ducts for $120 for the first joint and then $30 for each additional.  Ask one of our experts for more information about duct sealing.
