Pollution is no longer synonymous with just the outdoors. In fact Indoor Air Quality (IAQ) has become an important issue and concern today due to many contributors; inadequate ventilation, building materials, air borne contaminants: asbestos mold, bacteria, fiberglass, algae, dust, debris, moisture, and fungus just to mention a few that gather and circulate in the duct work. Such conditions can lead to SBS “Sick building syndrome”. The term “sick building syndrome” (SBS) is used to describe situations in which dwelling or building occupants experience acute health side effects that appear to be linked to time spent in a building or home. The complaints may be localized in a particular room or zone, or may be widespread throughout the dwelling or building. In contrast, the term BRI “building related illness” is used when symptoms of diagnosable illness are identified and can be attributed directly to airborne building contaminants.

Your air ducts may need to be cleaned if the following applies to you

  • Recent remodeling was done in the home? It may have left ducts filled with sawdust and drywall in the home/air ducts.
  • If the ducts haven’t been cleaned for several years. Your HVAC system may benefit from a good duct cleaning. Removal of cobwebs and debris can increase efficiency by as much as 40 percent.
  • Dust accumulation soon after house keeping- this would be a good reason to have your ducts cleaned, dust and debris may be interrupting the airflow.
  • Visible mold, rodent droppings and dead insects also tell you that professional cleaning is needed.

Side Effects of not Cleaning Your HVAC system

  • Health – Poor indoor air quality directly affects those occupants and even visitors exposed to it. Severity depends on how long they are exposed, AIR DUCT HOSE DIAGRAM, the level of contamination in the areas they are in and their level of existing health issues. READ more about SBS below.
  • Financial – The financial affect can be extremely costly. From lost time and productivity from staff due to illnesses related to the SBS, to increased payroll (overtime) due to higher maintenance complaint calls, to increased utility bills and/or repair cost to the HVAC unit for not functioning or working properly.
  • System Functionality and/or Lifespan- HVAC systems not regularly maintained and ducts not cleaned can contribute to the systems malfunctions, effectiveness, and lifespan of the unit itself.

How It’s Done

Air duct cleaning is done using vehicle mounted equipment. The attached vacuum is connected to a hose which connects to your air handler (furnace, a/c unit). Another one connects to the main supply and return air ducts putting your ducts under negative pressure. The technician addresses each vent to loosen/dislodge dirt and debris which is drawn to the hose connected to the air duct. The dirt and debris is then removed through the vacuum’s suction system in the vehicle. Our technicians are skilled and trained to perform this procedure using state of the art equipment such as Hepa Vacuum Systems which are 99.97% efficient, along with rotor brushes, air whips, high powered air nozzles, skipper balls (forward and reverse), octopus whips, predator whips just to mention a few.

This process is safe for your system and for your indoor environment. Our techs use the necessary precautions such as drop clothes and boot covers, to ensure your home is not compromised by the procedure, equipment and solutions used. Our clients are pleasantly surprised how clean the process is. We have gained a tremendous amount of experience by performing projects in a wide variety of industries and building types. We have also invested a lot of time and money to ensure our customers are getting quality workmanship and services.

We invite you to visit our Consumer Warning “News” prompter to learn more about the importance of why this procedure must be done properly and the risks involved, if not done correctly by a certified reputable company.
