Your heating, ventilation, and air conditioning system (HVAC) act as a collection source for a variety of contaminants that have the potential to adversely affect your health — contaminants such as mold, fungi, bacteria, and very small particles of dust. The removal of such contaminants from the HVAC system and home is an important step to improve your indoor air quality.
Research by the U.S. EPA has demonstrated that duct and system cleaning can cause your 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 effectively than dirty systems.
To clean your air ducts and ventilation systems, Greenwood Heating employs the Source Removal method of cleaning. Our qualified technicians place your 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. Some lower cost methods merely vacuum the duct. Our system actually scrubs each duct to get the dirt free using a vacuum and high-pressure air from brushes.
The Environmental Protection Agency says that “duct cleaning services typically range in cost from $450 to $1000 per heating and cooling system, depending on the services offered, the size of the system to be cleaned, system accessibility, climactic region, and level of contamination” and type of duct material.
