Air Conditioning Systems
Provide Good Conditions for Mold Growth!
The environment
in air conditioning systems (heat, moisture, dust) provides the
perfect conditions for microbial growth, which includes mold,
mildew, fungi, and bacteria.
(Reference this article : Life
Cycle of Mold) This contamination is very common in
the South where humidity is high and the air conditioning systems
are used almost year-round. Penicillium, claudosporium and
aspergillus are among the common microbes that can be food in homes,
schools and offices.
The first
indication of the presence of microbial growth is a foul, musty odor
which may be strongest when the ventilations system is running. If
the growth remains unchecked, headaches, itchy eyes, rashes and
respiratory problems may be expected by those who are prone to
allergies.
Carbon containing
materials that are abundant both indoors and outdoors may provide
the essential nutrients for growth. Sources of moisture are usually
the limiting and most important factor. They can come from high
humidity levels, condensation, and water intrusion due to a number
of events such as indoor leaks and floods. Temperature and light may
affect fungal growth, but are usually not a limiting factor since
most fungi can grow in light and total darkness.
Molds can cause a variety of
reactions in hypersensitive individuals ranging from allergic
responses to neurological damage. Molds may proliferate in almost
any indoor environment where excessive amounts of water and organic
matter persist.
The key factor in limiting mold
exposure indoors is to prevent growth through moisture control,
maintenance, and proper cleaning methods.
Prevention of
these conditions is the best measure to prevent mold inside the HVAC
system, but proper remediation once it has occurred is recommended
to provide the best indoor air quality.
