Air Duct Cleaning

The Real Dirt About Clean Air Ducts

Cleaning air ducts is a lucrative business. Which is great for the companies that do it, but not so great for their customers. That’s because most of the time, “dirty ducts” are created by leaks that exist in a home’s HVAC system. Dust and other airborne allergens get into the ducts through these leaks, and then are blown throughout the house. In newly built homes, dust and other particles get into ducts when they’re not properly sealed during construction.  As long as these duct leaks go unchecked, simply cleaning the ducts won’t solve the problem. But a duct blaster test will. A Duct Blaster® test determines the leakiness of your duct system. Once revealed, steps can be taken to seal existing leaks, thereby improving the energy efficiency of your home and eliminating potential problems like mold, rot, and temperature fluctuations that can be caused by leaky air ducts. After your home’s HVAC system is secured from leaks, the ducts can be cleaned, and you can breathe a whole lot easier knowing that your home is functioning at a higher level. 


Before you pay for duct cleaning, consider the following:

  • Have you done a Duct Blaster® test  to determine if your ducts are leaking?
  • Are your ducts in conditioned space?
  • Have you considered air-sealing so dust can't come in from areas with poor air quality like the attic, crawlspace or basement?
  • When was the last time you changed your air filter?
  • Is your duct system constructed of “duct board”
  • Are contractors bidding the job offering “negative pressure” duct cleaning?
