Air Duct Cleaning
Are there any health benefits that come from HVAC system cleaning?
Heating, ventilation, and air conditioning (HVAC) systems have been shown to collect a variety of contaminants such as mold, fungi, bacteria and very small particles of dust that have the potential to affect overall health, The removal of such contaminants from the HVAC system and home should be considered one component in an overall plan to improve indoor air quality.
How can I determine if the HVAC system cleaning was effective?
The best way to determine if the HVAC system cleaning was effective is to perform a visual inspection of the system before and after cleaning. If any dust or debris can be seen during the visual inspection, the system should not be considered cleaned. While you can perform your own visual inspection using a flashlight and mirror, a professional cleaning contractor should be able to allow you better access to system components and perhaps the use of specialized inspection tools. In addition, following the Homeowner's Guide to Air Duct Cleaning can help to ensure a top quality job.
How often should residential HVAC systems be cleaned? Frequency of cleaning depends on several factors, not the least of which is the preference of the homeowner. Some of the things that may lead a homeowner 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.
