In today's 2018's air-tight homes, indoor air quality is a growing concern.
Most household dust contains dust mites, mold, mildew, pollen, and animal dander. Many of these contaminants are circulated through the central air systems in most homes and can aggravate the systems of asthma and allergies.
Air Duct Cleaning is especially useful for those of us who do not like dust on everything. The reason that dust accumulates on ceiling fans and other furniture is that the air ducts in the home are dirty. Poor quality air filters in the return (where the air sucks into the system) is usually the culprit. Once the dust gets into the system, it spreads throughout the ducts, and as a result, blows the dust out the registers and into the rest of our home.
