Chances are you’ve never looked in the air ducts of your HVAC, and if you did, you probably wouldn’t be happy. Well, know this, pollutants in your house accumulate in your air ducts and present a hazard as you breathe in the air that comes out of those ducts; al-lergens, dirt, dust, and microbial material—they all hang out in those seldom-though of air vents. According to Jason Powell, owner of Breathe Clean, air ducts should be cleaned out, on average, every three to five years. “If you wake up in the morning and start sneezing, chances are it’s from something in you air ducts,” explains Powell. He also notes that if you are running a swamp cooler, there is a greater chance of moisture building up in the duct work that can add to mold growing in the vents. “And since dust and other particles settle to the ground, your pets are usually the first to be affected by dirty air ducts.” Jason explains, “The fine dust particles can get into your lungs, leading to a lowering of your immune system. That can lead to more colds or other illnesses that seem to be recurring.” Jason has a process that scrubs your vents clean using negative air and collecting all the nasty stuff in your vents into a High Efficiency Particulate Air (HEPA) filter. He backs up the procedure by providing a before and after look at your air ducts via a high definition camera. Jason half-way joked, “It’s like performing a colonoscopy for your air ducts.” Another important aspect of having clean air ducts is that during the cleaning procedure, Jason can inspect the condition of the duct work. “I see issues in about 40% of the ducts that I inspect that can then be repaired, leading to a more efficiently running system. Look at your air intake filter—when is the last time it was changed? If it looks totally covered with dust, just imagine what the inside of the air ducts must look like. If you’ve lived in your home for several years and never had your ducts cleaned, you might consider it—and start breathing easier!
