About Indoor Air Quality

Indoor air can be more polluted than outside air.  Dust, pollen, mold spores, animal dander and much more are Indoor air pollutants.

Alliance Environmental uses only the highest quality equipment and products. You can rest assured that you will breathe easier once our service is complete.

All Turbojets can be run horizontally for easy attachment to floor registers or to connect to basement ducts without taking them down stairs.

Why should air ducts be cleaned?

  • Studies have shown that indoor air can be two to five times MORE polluted than outside air.
  • Most disposable filters remove about 10% of these pollutants allowing 90% to enter the air system, even during the construction of a new home.
  • The pollutants contain dust, pollen, mold spores, animal dander and much more.
  • These materials collect in the furnace, air conditioner and duct surfaces, just as they do on the furniture and floor surfaces.
  • The furniture and floor are cleaned regularly but the duct surfaces are hidden from view and can only be reached by specialized duct cleaning equipment.
  • These pollutants can migrate out into the room again, or become a food source for mold and bacteria, which can thrive in this dark comfortable environment from high humidity or moisture from the air conditioner or humidifiers.
  • Biological growth can release mold spores or toxins into the air system.

Can mold grow in a duct system and what problems can it cause?

  • Mold spores require a stable temperature, a food source and moisture to live and reproduce.
  • Dust and dirt that go through the filter are a good food source.
  • The furnace/air conditioner is designed to maintain a comfortable temperature, and moisture is available from humid conditions in the environment, the humidifier in the furnace or the cooling coils in an air conditioner.
  • Live molds can release spores that will trigger allergic or asthmatic reactions, sometimes severe, in about 10% of the population.
  • Mold both living and dead can produce toxins that may cause short term allergic reactions.
  • Long term exposures to low levels of some mold toxins can result in permanent chemical sensitivity to common compounds in the environment.

Only Alliance Environmental Group can give you the best advice on cleaning your air ducts and indoor air using a unique package of services.  Alliance Environmental can use either or both the  ThermaPureHeat system and the Air-Care system.

Will a dirty air system result in higher energy costs?

  • Depending on the amount of contamination and its location, energy consumption could be increased. If the fan blades, evaporator coil or other control components of the system are heavily contaminated, the system may have to run much longer to cool or heat the occupied space, wasting a lot of energy.

Which parts of the air system should be cleaned?

  • There are three major parts to an air system:
    1. The supply and return grills;
    2. The interior surfaces of the supply and return vents;
    3. The furnace/air conditioner air handler.
    4. All three components must be cleaned. If only one or two of the components are cleaned, the contaminates from the third component will rapidly contaminate the ones that were cleaned.

How often should I have my air ducts cleaned?

  • Once an air system is thoroughly cleaned, it should remain clean for three to seven years if properly maintained and a high resistance filter is installed.
  • A standard disposable filter only stops about 10% of the airborne contaminates, allowing 90% of the dust in the room to flow back into the air system.
  • To maintain protection against biological growth, an EPA registered biocide should be applied every 6 to 12 months by Alliance Environmental.

What are the sources of air duct contamination?

  • All inside air was once outside air, so all of the dust, chemicals, pollen, insects and mold spores in the outside air can be pulled into the air system.
  • People shed millions of tiny dead skin cells every hour.
  • Cooking smoke, household insect sprays, personal care products are also a source of pollutants.
  • Many construction materials, carpets, wood products and plastics give off pollutants as well.
  • During construction or remodeling activities, many types of dust are produced and find their way into the duct work.
  • If the duct components were stored outside prior to construction, they may have collected dust, rain water and even mold before they were installed in a system.

What does it cost to have a whole air system cleaned?

  • This can depend on a lot of factors, such as the size of the home, the number of supply ducts, how long since the ducts were cleaned, etc. The whole system should be cleaned and a more efficient filter installed to keep the system clean longer.

Alliance Environmental Group’s Air-Care Steps:

  • Vacuum the interior surfaces of the Furnace/Air Conditioner.
  • Clean the cooling coils with a HEPA vacuum and a coil cleaner.
  • Clean the Blower unit.
  • Use the Automist fogger to decontaminate the interior surfaces with Sporicidin EPA registered Biocide.
  • Wash Register with Dynamite cleaner and rinse.
  • Plug supply duct openings with foam register plugs.
  • Block return by placing the filter in a plastic bag and installing in the unit.
  • Attach the TurboJet negative air machine to the system. It can be attached to a Floor Duct or the Furnace Plenum with an Adapter Plate. The Pogo Pole Hose Adapter can be used to connect to ceiling and wall ducts.
  • The Cobra Power Brush will aggressively remove duct debris.
  • The Sidewinder Air Powered tool will remove duct debris more gently
  • Decontaminate cleaned ducts with Sporicidin, Soot set sealant, and Odor Kill Deodorizer
  • Install Solid Odor Kill in the return to control odors for up to 3 months
  • Remove the bagged filter from the return and install an electrostatic air filter.
