The Environmental Protection Agency (EPA) conducted research to measure dust levels and HVAC system efficiency in test homes over a one-week period during the cooling season. The results showed that duct cleaning did not have a significant impact on dust levels or system performance. The governments of the United States and Canada, as well as health professionals who have studied duct cleaning, do not recommend it as a routine measure. However, the CMHC researchers found that when duct cleaners also cleaned the fan blades, there was a slight decrease in airborne particles.
A professional duct cleaning service can provide many benefits to homeowners. It allows the technician to inspect the ducts for any leaks or kinks, especially in flexible ducts. This is because much of the dirt in the air ducts adheres to the surfaces of the ducts and does not necessarily enter the living space. In addition, air duct cleaners may also clean heating and cooling equipment such as heat exchangers, cooling coils, condensate drain buckets, fan motors, blades, and fan housings. The technician will begin by shaking the duct walls and removing contaminants such as dust, dirt, pollen, bacteria, and other unpleasant substances that are stuck to the duct walls.
They will use powerful vacuuming tools to clean the ducts and may also use inspection tools such as a simple mirror or periscope or even a CCTV camera system with flexible cables to reach hard-to-reach parts of the air duct system. If you or someone in your family has asthma or allergies, you may be considering hiring a reputable and specialized duct cleaning company such as Calvey Heating And Air Conditioning to clean your home's air ducts. To combat negative experiences with air duct cleaning services, the National Air Duct Cleaning Association (NADCA) created a standardized method for cleaning air ducts. While duct cleaning may not significantly improve air quality or reduce heating costs, it can help reduce allergens and improve indoor air quality.
