How Duct Cleaning Improves Air Quality

You may not realize how much dust, dirt, and other debris can become trapped inside the ductwork that runs through your walls and ceiling. Because ductwork remains mostly out of your sight, you won’t notice the thick layers of dust that will begin to cost the interiors of the ventilation shafts after only a year without cleaning. You may keep the rest of your house spotless, but inside the ductwork hides a growing source of air contamination that requires professionals to eliminate it.

How Does Duct Cleaning Improve Indoor Air Quality?

Just like modern homes maintain a strong seal against outdoor air, ductwork contains airtight seal along its length to prevent air escaping to assure maximum HVAC efficiency. But there’s a downside to this: the dust and other particles that the HVAC system draws in through the return air vents will start to gather inside the channels with no way to escape… except to get blown out through the exit vents and into the living spaces, where will circulate once more into the return vents. More particles will join it, and the reservoir of pollutants inside the ducts will grow.

Consider this fact: an average six-room home will circulate a total of 40 lbs. of dust through it each year. The majority of this dust will remain inside the ductwork, where normal household cleaning cannot reach it. Without allowing outside air to filter through the home—which is impossible during the colder and hotter times of the year—none of this contamination will dissipate. It will instead lower air quality, leading to allergy-like symptoms, skin- and eye irritation, breathing, and in some cases serious illnesses.

A professional duct cleaning job will remove most of the pollution inside ducts. Professionals use high-powered vacuums to put the ventilation system under “negative pressure” to agitate dust, dirt, and other debris from the duct walls; this makes it easy for the suction to remove the particles. Duct cleaners also address specific areas using rotary brushes for the most thorough cleaning possible.

If you have not yet had duct cleaning for your home, you need to schedule it as soon as possible and put a stop to the decline in indoor air quality. Call Black Hills, Inc. Heating & Air Conditioning and arrange for our trained cleaners to sweep away the hidden dust and dirt from your home.
