Stats & Charts

Modern industrial engineers typically use predetermined motion time system, computer simulation, along with extensive mathematical tools for modeling, such as mathematical optimization and queueing theory, and computational methods for system analysis, evaluation, and optimization.

Our Solutions & Benefits

Another instance in which air duct cleaning is advantageous to one’s office or home is when air ducts are infested with any animals or vermin. Again, this job may require an exterminator as well as an air duct cleaning company to clean any traces of the animals after the exterminator has removed the animals themselves.

Finally, when dust and debris is visible inside the air ducts, an air duct cleaning service will be beneficial. Better air flow will make for improved efficiency in your heating and cooling system, and in many instances, will improve the quality of your indoor air.

A thorough inspection of the ducts

Consider it a sign of competency when your technician initially inspects the supply and return registers prior to commencing with the cleaning process. This step allows the technician to determine the extent of build-up before cleaning, to know if there are signs your central air ducts need cleaning, as well as check for leaks and other duct issues that require attention.

Use Negative Pressure Vaccum

Creating negative pressure is an effective way to clean your ductworks, so you do not end up inhaling polluted indoor air.

Here are the steps to air duct cleaning process with negative pressure:

  • The vacuum collection device’s hose is hooked to a duct close to the air handler.
  • The cleaning contractor will need to cut a hole in the duct, insert the vacuum hose and seal it tightly
  • The next step is to seal the registers
  • Turn on the vacuum unit to create negative pressure

Agitate The Dust

Your specialist will use strong suction gear to clean the ducts as they go through the air duct cleaning steps.

Problem with settled dust?

You don’t have to worry as your technician is equipped with powerful instruments, including a revolving brush and air whipping tools to stir movement of settled dust.

The supply-side ducts and return vents will be cleaned, and expect your air duct contractor to remove settled dust from the main lines, allowing for more efficient vacuuming.

Clean the HVAC system and the furnace

Reassessing your HVAC system is imperative once the ducts and vents have been cleaned.

Note that the NADCA (National Duct Cleaning Association) suggests cleaning all the HVAC components, including the blower motor, drain pan, and evaporator coil. The cleaning of these components contributes to the improvement of the quality of air circulating in your home.

What is Included

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.

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.

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.

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.

Antimicrobial chemicals are applied by some companies to the interior surface of the air ducts to treat microbial contamination such as fungi (mold), viruses or bacteria. Before any antimicrobial chemicals are used, the system should be thoroughly cleaned. It is critical that any antimicrobial treatment used in your system be registered by the U.S. Environmental Protection Agency specifically for use in HVAC systems. The use of antimicrobial chemicals is an additional service that is not part of a typical air duct cleaning project.
