THE MAIN REASONS FOR CLEANING AIR CONDITIONING DUCTWORK:

Blowing dirt
Dirt buildup
Microbial growth
Clogged air passages
Odors

HVAC (Heating, Ventilation, and Air Conditioning) cleaning has been around since the advent of air conditioning. But in recent years, it has taken on a greater importance. With the buzz phrase "Indoor Air Quality" seeping into the public consciousness, more people are becoming aware of the quality of air in the buildings they inhabit.

A Japanese study showed that when dust accumulations in a duct exceed 0.8 millimeters, particles can begin to blow out. Resulting problems can range from more dust on the furniture to blasts of dirt in a surgery room when the air conditioning comes on.

The dirt within a duct is a hodgepodge of whatever is floating in the air. Common particles include flakes of human skin, animal hair and dander, fungi spores, vehicle emissions particles, and soil dust. Since all of these can act as allergens to sensitive people, a buildup of these in a duct system can provide a potential pool of irritants to those who suffer from allergies.

In extreme cases, dirt buildup can become so heavy that the movement of air through the duct is restricted, resulting in less air output at increased energy costs.

Microbial growth in HVAC systems tends to occur wherever dampness is found. In California and the West, this is normally restricted to the air handler. (In humid climates, the entire duct system may be susceptible.) Microbial growth can result in higher air concentrations of microscopic organisms (fungi, bacteria, algae, etc.). This can result in illness or symptoms of illness (headache, nausea, sore throat, etc.) in building occupants. In extreme cases this has resulted in legal threats or action by building inhabitants.

Standard duct cleaning procedures can dramatically reduce or eliminate microbial growth. More information on HVAC cleaning can be obtained at the Website of the National Air Duct Cleaners Association: www.nadca.com
