Do You Have A Sick House?

A sick house is a house with a serious air quality problem. An area can be described as "sick" mainly because people who reside inside it for an extended period can develop symptoms of illness such as headaches, watery eyes, nausea, skin disorders, and fatigue. The illness causing factors vary and can include a build-up of air pollutants from household products, building materials, formaldehyde, and/or respirable particles. In humid climates, sick houses are usually houses with a serious moisture problem. Moisture also plays an important role in promoting the growth and spread of mold (mildew). Molds produce spores, tiny encased "seeds," that float in the air. When a home is severely contaminated, thousands of mold spores can be suspended in each cubic foot of air. When people are repeatedly exposed to mold spores, they can develop allergic symptoms.


How Air Conditioners Cause Mold Problems

Visible mildew and mold is easy to identify because of its discoloration and odor. Keeping humidity in a home low can help keep visible mildew from returning, but if mold spores get into the air conditioning system, they can settle in the air conditioning ductwork, along with dust and other contaminants, where you can’t see or smell them. This is a worst case scenario because duct systems in humid climates are incubators for microbial pollutants like mold and bacteria. With the alternating high and low humidity conditions that regularly occur in air conditioning ducts during normal AC use, mold will grow, produce spores, and spread throughout the house.

Inhibiting Mold Growth in Air Ducts

Soil Build-up in Air Ducts

Effective filtering is a huge part of keeping ducts clean. If you have pets, plants, or other unique factors at play in your home, consider upgrading to a newer kind of filter the next time you swap them out. Newer filters can now remove smaller particles, and more of them as compared with the older fiberglass filters. By neglecting to clean or change your filters, the build-up of dust and dirt on air conditioning filters causes air to by-pass the filter and carry organic dirt and spores into the ducts. Leaks around duct joints in attics can also introduce dust and spores. Duct Moisture Moisture in air ducts is nearly unavoidable, as the air leaving the evaporator becomes saturated as part of the AC’s normal process. If you run your air conditioner for the majority of the year, this leaves little time for that saturation and moisture to actually dry up. High moisture can cause any dirt present in the duct to become caked on and provide an environment for mold to grow. The best way to address this issue is to either use the air conditioner less frequently or to clean the ducts regularly to clear out any caked on dirt and moisture.

FACT: Air ducts have more germs than a chicken coop (American Lung Association) 

FACT: A build up of 0.42 inches of dirt on a heating or cooling coil can result in a decrease in efficiency of 21% (EPA)

FACT: 9 out of 10 heating, ventilating, air conditioning systems failures are caused by dust and dirt (Louisiana Coop Extension Service) FACT: 50% of all illnesses are either caused by, or aggravated by, polluted indoor air. (the American Medical Association and the American Medical College of Allergists.) 

FACT: Children and the elderly are especially affected by indoor polluted air. (Dept. of Consumer Affairs) FACT: One out of six people who suffer from allergies do so because of the direct relationship to fungi and bacteria in the air duct system. (Total Health and Better Health Magazine) 

FACT: The proportion of buildings with mold growth in North America is perhaps as high as 20 - 40%. Data from the United States suggests that 40% of buildings are moldy. (Mold Health Guide, Phillip Fry) Since all the air in your home circulates through your air ducts, anytime you use your furnace the dust circulates too. Although the filter in your furnace helps trap some of this dust, much still settles on the inside of your air ducts. Over time, it can build up into a thick layer. Even though it settles, it doesn’t stop circulating in your home. Some of it is picked up by the air flowing through your ductwork and re-enters the air in your rooms. If you look closely at the heat register in a room you don’t use often, you can see the dust on the openings. That’s just a tiny fraction of what lies behind the register and lines every square inch of your ductwork.

Additional Information

NIkki.C : "Tom was very knowledgeable and detailed in explaining the duct cleaning process. It is evident that he is very passionate about his work, and he genuinely cares about producing the best results possible. I have chemical sensitivities and the natural products he used did not make me sick. The company also offers an amazing guarantee. I would definitely recommend and use them again."


Jeniffer.M : "Tom is very professional, and he did a terrific job for me. He explained to me every single detail with no doubt before he did the work. During his work, he is very patient and check everything carefully. Then he cleaned every vent and everything look like new. Since I bought less than one year and I could smell dust  in most of time. His hard working make my house smell good again. And finally we get the good air, thanks to Tom. I appreciated his perfect work."


Monica.R : "Tom and Aaron came on time as discussed. They explained to me in detail what the process entails, as this was my first ever duct cleaning service. They attached the giant blower which was left on for 20-30 min and was shown the dirt that had been pulled from all the vents in my home. They also showed me how my AC unit needed to be sanitized as there was dirt build up around and inside the unit and that they provide that service too. We went to my laundry room and they cleaned out the dryer ducts and cleaned up well, after themselves. I highly recommend this service to all."
