Wherever you find an air handling system and building occupants, you’ll find the potential for poor indoor air quality and the need for ventilation duct cleaning. Air duct cleaning can reduce indoor environmental contaminants by removing the breeding ground for microorganisms from the air duct system.
Fungi and bacteria in ventilation systems can contaminate indoor environments and cause a variety of health effects. Many organisms cause allergic-type reactions, such as headaches, runny nose, and itchy eyes. Some fungi and bacteria can cause respiratory infections, especially in immune-comprised individuals.
A study by the National Institute of Occupational Safety and Health indicates that occupants in buildings where ducts have never been cleaned are 60% more likely to develop respiratory ailments.
If you question the need for air duct cleaning, take a look behind the return air grilles in the HVAC system of your home. Many people have found that one glimpse into the air ducts provides all the evidence they need to initiate a thorough cleansing of their HVAC system.
The common household dryer is blamed for more than 15,000 fires a year, up to 30 deaths annually and 300 injuries. When dryer vents become clogged with lint, it makes the dryer work harder. This can cause the dryer to fail; with a gas dryer it can be a fire hazard. A clogged dryer vent will lessen your efficiency, costing you more money to run your dryer. If you have to run your dryer more than one cycle to dry towels, jeans, or heavy linens, your dryer vent may need cleaning.
