Heating, ventilation, and air
conditioning (HVAC) systems have been shown to act as a collection
source for a variety of contaminants that have the potential to
affect health, such as mold, fungi, bacteria, and very small
particles of dust. The removal of such contaminants from the HVAC
system and home should be considered as one component in an overall
plan to improve indoor air quality.

Frequency of cleaning depends on several
factors, not the least of which is the preference of the home owner.
Some of the things that may lead a home owner to consider more
frequent cleaning include:
 Smokers in the household.
Pets that shed high amounts of hair and dander.
Water contamination or damage to the home or HVAC system.
Residents with allergies or asthma who might benefit from
a reduction in the amount of indoor air pollutants in the home's
HVAC system.
After home renovations or remodeling.
Prior to occupancy of a new home. |
