Airduct Frequently Asked Questions

"Are there any health benefits from cleaning my HVAC system?"

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.

"Will cleaning my HVAC system reduce my energy bill?"

Research by the U.S. EPA has demonstrated that HVAC system cleaning may allow systems 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 effectively than dirty systems.

"What is the best way to clean my home's air ducts?"

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 my air duct system 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; After home renovations or remodeling; and, Prior to occupancy of a new home.
