One of the most common air conditioning service questions is, “When do I need an air duct cleaning?” The concern comes as a direct result of homes becoming more energy efficient and environmentally friendly. Roughly 40% of the average home’s energy usage is from heating and cooling. Efficiency requires air sealing the home to keep energy from escaping. As a result, this can trap pollutants in your house.

Over time, dirt, dust, pollen, mold spores, and bacteria get trapped in your home and reduce your home’s indoor air quality. Will air duct cleaning improve the indoor air quality? Many will say no, there is no improvement. However, that is not exactly accurate. A correct answer is more complicated because of limited studies. Ultimately, needing an air duct cleaning is more than just because the ducts look dirty.

You should get an air duct cleaning when:


  • There are visible signs of mold,
  • Pests and rodents are inside the ducts, or
  • When dust and dirt are coming from the supply registers.


If you do need an air duct cleaning, this is not a do it yourself project. Your air conditioning system relies on your duct work. Ducts that become poorly connected and leak reduce your system’s efficiency and will increase energy costs.
