General Duct Cleaning Info
The quality of indoor air is one of the top five environmental dangers to the general public. Indoor air quality is effected by pollutants that are trapped and then circulated throughout the house or building through the air duct system. According to the American Lung Association and the EPA the average person spends 60 percent to 90 percent of their time indoors and is then exposed to the indoor air quality. Duct cleaning removes dust, dust mites, and other contaminants from the air duct system and prevents them from being circulated continuously.
Allergies and AsthmaAir conditioning ducts have shown to become an ideal place for spores and other micro fungus to develop and grow. Due to the dark nature of the duct and the available nutrients from outside pollutants the duct can become a breeding ground. Allergies are becoming a common problem among Americans and with over half of all available time being spent indoors the increase of allergies is expected to be related to fungi and bacteria growing in air duct systems. Asthma is similar to allergies in that the number of those who suffer from asthma is rising. The Chicago Tribune reported in 2004 that 86 percent more people suffered from asthma in 1996 than they did in 1980. This increase is again attributed to more pollutants entering home and building air duct systems and the increase amount of time people spend indoors.
Dirty ducts have been linked to illness, such as; strep,headaches, fatigue, itchy eyes and nausea. Also asthma and legionella pneumonia have been linked to large amounts of accumulated dust and mold.
Heating and Cooling Benefits
Simply put, a clean system runs better than a dirty system. Dirt & dust equal stress on mechanical components. Just changing your furnace filter is a waste a time if you also don’t have clean ducts. Picture your HVAC system as a circulatory system. If the entire system isn’t cleaned the dirt leftover will just re-circulate through the system, contaminating everything again instantly. It’s sort of like changing your oil filter in your car without changing the oil.If an air duct is allowed to become overly dirty it can hinder the flow of air as it passes through the ducts. Even a minor build up of dirt on a cooling coil can reduce the systems efficiency significantly. Reduced efficiency of the heating and cooling systems results in the system running longer, and increased energy costs as well as more wear and tear on the equipment. Cleaning out air ducts can save money on the next years heating and cooling bill and help pay for the duct cleaning.
Interesting Air Duct Cleaning Facts
People want to know the facts about Indoor Air Quality (IAQ) and if air duct cleaning will do much to improve the quality of the air we breath. The facts stated below should help you understand that duct cleaning is an important step in improving IAQ. Duct cleaners across the USA agree that cleaning air ducts helps to significantly reduce the source the source of contaminants and various pollutants which may trigger adverse health reactions.
Heating and air conditioning ducts which are dark, damp and rich in “nutrients” provide an excellent breeding ground for mold, fungi and dust mites. These allergens can spread rapidly since the air ducts are used to heat and cool the house. Poor ventilation allowing fresh outside air indoors and dirty filters are also major contributors to unhealthy contaminates in the home. Mold and fungi can cause “discomfort”, infections and commonly trigger allergic reactions.
While it is true that air duct cleaning alone does not cure health conditions like Asthma, allergies and other respiratory related conditions, vent cleaning does however, play an important role in prevention and treatment. By cleaning your HVAC system you will remove allergens like dust, and pet dander from the duct work as well as residue from cigarette smoke. While the EPA does not have any recommendations for how often your air ducts should be cleaned, your furnace manufacturer does. Most furnace manufacturers recommend having your furnace cleaned and inspected annually, which begs the question; If my furnace should be cleaned every year, what about my air ducts? We dont recommend that you need your ducts cleaned annualy though. The proper time frame is every 3-5 years, depending on factors like pets, smoking and location of house.
Indoor Air Quality Facts
- The EPA has claimed that indoor air pollutants have been found to be 70 times more polluted than outdoor air. Since we spend 60-90% of our time inside our home, it is essential that that air be the cleanest. (American Lung Association & EPA)
- Indoor air pollution is ranked among the top 5 environmental dangers to the public. (EPA)
- Studies have shown that two out of three indoor air quality problems involve the HVAC/Air Duct System.
- Children and the elderly are especially affected by polluted indoor air. (Department of Consumer Affairs)
- Volatile Organic Compounds (VOCs) in indoor air can be 2 to 5 times greater than in outdoor air. (EPA)
- 20% of all illnesses are either caused by, or aggravated by, polluted indoor air. (American College of Allergists)
- The average 6-room house collects 40 pounds of dust each year. (Discover Magazine)
Facts About Allergies
More than 50 million Americans suffer from allergies.- One out of six people who suffer from allergies do so because of the direct relationship to fungi and bacteria in air duct systems. (Total Health and Better Health Magazines)
Facts About Dust Mites
- Each person can shed up to 700,000 skin scales per day creating an abundant food source for dust mites.
- About 40,000 dust mites can “thrive” in only one ounce of dust
- Approximately 10 to 15 percent of the population suffers from an allergy related to dust mites.
