Homes have been found to have 10 to 100x higher pollution levels than the outdoors, and Americans spend up to 90% of their time indoors. Because the ventilation (HVAC) system heats, cools and circulates the air in your home, house dust, pet dander and the like gets trapped and collects inside the system resulting in decreased efficiency and an increased possibility the ventilation system is circulating and adding to the indoor air pollution in your home.
If left for a long period of time, a dirty ventilation system may be the largest cause of house dust and allergy problems, as well as the leading cause of ventilation system failure. MBM is an authorized dealer of Goodman, Amana, Carrier and Trane heating and cooling systems. MBM Cleaning and Restoration is also a NADCA and VSMR certified company that uses Negative Air Pressure and HEPA Filters in their proven cleaning process. In addition to brushing and vacuuming your ventilation system, MBM cleans the coil, blower and plenum box as well as decontam-inating and sanitizing the entire system.>> See complete air duct cleaning procedures here
A clean system restores capacity and lessens running time (clean systems save money!) reports the Louisiana Cooperative Extension Services (LCES). A well-maintained system may reduce your utility bill by as much as $30.00 per month (over $300.00 per year).
A well-maintained system improves humidity control and reduces running time according to the Air Conditioning Contractors of America (ACCA) of Greater Houston.
Cleaning and maintaining the ventilation system on a yearly basis (read up on Dryer Vents here), using a NADCA certified and HEPA filter using company (as recommended by the EPA), can significantly reduce house dust and microbial contamination as well as save money in energy and repairs. For particularly sensitive individuals and those living in very high humidity environments, the system should be cleaned every six months.
A clean ventilation system can be used to help decrease allergy and asthma symptoms. Air-conditioning can keep humidity to 50% or less to significantly slow the growth of dust mites, molds and mildew (read up on Filters here).
The EPA reports a buildup of less than a 16th of an inch, 0.042 inches of dust, on a heating or cooling coil can result in a decrease of efficiency of 21%. 9 out of 10 system failures are caused by dust as reported by the Louisiana Cooperative Extension Services (LCES).
Ventilation systems in areas of high humidity may become damp. Such systems are perfect environments for molds, mildew and other microbes and microorganisms to flourish. When such a system is then turned to heat in the less humid winter season, the dust and contaminates dry and become air born. Such a system becomes a seasonal contaminator, growing, releasing and circulating contaminants over and over again.
Along with house dust and molds, construction debris is also a major contributor to buildup in the ventilation system. Newly constructed homes should have their systems cleaned before move in and systems should also be cleaned immediately after home improvement projects.Seriously consider having the ventilation system cleaned in any home that is new to you.
There are many different types of molds and, except for causing asthma symptoms in sensitive individuals, most molds are relatively harmless and easy to get rid of. However, there are some molds which are harmful to all individuals and an extreme case of contamination of even mild molds can cause symptoms in most people.
Finding mold contamination early is the key. Molds thrive particularly in dark, warm, damp places. Be especially observant of kitchens, bathrooms, closets, basements, and crawl spaces. Contact a microbial remediation-certified service provider like MBM if you suspect you may have mold in your home.
