Indoor environmental contaminants significantly affect the productivity
and efficiency of your facility and employees. 

These contaminants may also be a distraction and deterrent to your customers and clients.

Numerous problems can result from the persistent presence of these contaminants in your facility:

• dust and mold deposits
• allergic sensitivity
• health-related absenteeism
• loss of or damage to records/files
• HVAC equipment breakdown
• respiratory tract infections
• equipment damage
• higher energy consumption
• strong or musty odors

Indoor Environmental Hygiene

Indoor Environmental Hygiene is an increasing concern as modern buildings become more tightly sealed, having less interchange with outside air.  This is good for energy efficiency, but it also provides opportunities for poorer Air Quality and microbial contamination.  Consider the benefits of pursuing a higher standard of Indoor Environmental Hygiene:

• Reducing or Eliminating Odors:  Mold and bacteria growth in HVAC systems or in areas with excess moisture causes musty odors.

•  Reducing Equipment Breakdown/Loss of Records:  HVAC systems run more efficiently and at lower operating temperatures when they are free of dust, dirt and microbial contamination.  Microbial contamination can damage and destroy important records and material necessary to your operations.

• Reducing Absenteeism:  Respiratory tract infections account for much of employee absenteeism; dust and microbial contamination can be a contributor or even cause of these infections. 

HVAC System Hygiene

The Air Quality Systems field technicians employ state-of-the-art equipment to ensure the highest cleaning standards.  All HVAC Hygiene Remediation Project Design and On-site Management is performed under the supervision of NADCA-certified Air Systems Cleaning Specialists (ASCS).

Air Quality Systems practices source removal, the only method recognized by the U.S. Environmental Protection Agency as fulfilling all requirements to clean your air system.  Air Quality Systems uses portable equipment specially designed for ductwork cleaning which provides the air and vacuum pressure necessary to clean your system.

• AQS begins by thoroughly inspecting the HVAC system, designing a remediation plan according to the needs of the facility and the condition of the Air System.

• We sweep the duct work with 200lbs of applied air pressure while the vacuum hose
  pulls 5,000 cubic feet per minute back out of the duct work.  The vacuum
  equipment pulls the dust, mold and debris into a specially sealed compartment .  Our portable Vacuum Systems utilize HEPA (High Efficiency Particulate Air) filters, capable of trapping 99.97% of particles down to .3 microns in size.  Debris in the ductwork is loosened and removed by a combination of our rotary brush unit, air whips, and manual brushes on flex-rod sections, then driven to the portable HEPA vacuum units.

• Heating/Cooling coils and pans are thoroughly cleaned as necessary with detergents and pressure-washed with our portable power wash system.  Wastewater is controlled through the use of a HEPA portable Wet/Dry Vacuum.

• HVAC fan housing and blower units are cleaned with vacuum and compressed air, then pressure-washed as necessary for final cleaning.

• Degraded or contaminated internal fiberglass acoustic insulation in air handlers
  and ductwork is replaced as necessary or coated with an approved
  non-toxic, polymer/latex treatment.

• All supply, return and exhaust diffusers, registers and grills are cleaned.

• At your request, we will use special disinfectants on your systems and ductwork.  If specified, your Air Handling System will be treated with an EPA-registered sanitizing agent to mitigate microbial growth and possible bioaerosol contamination.

• If you have special considerations and/or specifications in the cleaning and care of your HVAC system, we will strive to efficiently and thoroughly make your system clean and suited to your needs.

• Upon completion, AQS provides a post-project inspection of the HVAC System, ensuring that proper hygiene specifications and project goals have been met.
