Most people are now aware that indoor air pollution is an issue of growing concern. As an answer to these problems, many of us are seeking our whole house duct cleaning.
My opinion on duct cleaning? If you’re considering having your ductwork cleaned to reduce the dust and potential allergens in your home, forget about it! That’s the job of your furnace systems air cleaner or filter. Once dirt enters into your duct system, the only way it can get out of there is to get past your filter system. As long as you have your filters or better yet, high efficiency air cleaners in place, that problem is solved. What duct cleaning is good for is an overall healthy home approach to cleaner living.
After even as short a period as 10 years, your ductwork may become contaminated with particles of dust, pollen or other debris. If moisture is present, the potential for microbiological growth (e.g., mold) is increased and spores from such growth may be released into the home's living space. Some of these contaminants may cause allergic reactions or other symptoms in people that can become an extreme health hazard.
You may want to consider having the air ducts in your home cleaned if:
• There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system.
• Ducts are infested with vermin, e.g. (rodents or insects)
• Ducts are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers due to an inefficient air cleaning system.
After your ductwork has been properly scrubbed clean, a sealing solution should be used to prevent any uncollected dust from reentering the air stream. In many cases, an anti-microbial sanitizing solution may be applied also.
Depending on your duct systems air filtration equipment, duct cleaning in many cases will promote a cleaner and healthier environment for both you and your family.
