Are there any Health Benefits that come from HVAC system cleaning?
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, pollen, dust mites, 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.
Will HVAC system cleaning reduce our Home Energy Bills?
Research done by the U.S. Environmental Protection Agency has demonstrated that HVAC system cleaning may allow system to run more efficiently by removing debris from sensitive mechanical components. Clean, efficient systems are less likely to break down, have a longer life span, and generally operate more efficiently than dirty systems.
How should a residential HVAC system be cleaned?
The most effective way to clean air ducts and ventilation systems is to employ Source Removal methods of cleaning. This requires a contractor to place the system under negative pressure, through the use of a specialized, powerful vacuum. While the vacuum draws air through the system, devices are inserted into the ducts to dislodge any debris that might be stuck to interior surfaces. The debris can then travel down the ducts to the vacuum, which removes it from the system and the home.
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 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.
