  • Duct Cleaning

    How you can select an air duct cleaning
    company?

    There are health benefits for all occupants from regularly cleaning
    the Heating, Ventilation, Air Conditioning (HVAC) System.


    Heating, ventilation, and air conditioning (HVAC) techniques collect mold,
    fungi, bacteria as well as a variety of contaminants that reduce
    the high quality of the air residents and website
    visitors breathe. A dirty air duct contributes to poor
    indoor air quality plus affects the health of people in the residence.


    The purpose of residential air duct cleaning is to remove these
    contaminants from a home's HVAC system to get the best indoor air quality.


    The most effective way to clean an air duct and/or ventilation system is to
    use a specialized, effective vacuum which puts the air
    duct / ventilation system under unfavorable pressure.
    While the vacuum draws air through the system, devices are inserted into the
    ducts to dislodge pollutants and debris from the interior surfaces,
    moving the contaminants/debris from the home's air
    ducts and ventilation techniques into the vacuum.


    Vacuum collection alone does not clean the HVAC system.
    Brushes, air whips, "skipper balls" and other tools that agitate
    contaminants and debris scrub the areas within the air duct system and propels contaminants and debris to the vacuum
    collection device(s).

    Anti-microbial chemical sanitizers are applied to the interior surface area of the air ducts to control microbes contamination...

    but... before sanitizers are utilized, the system should be
    thoroughly cleaned. Almost all anti-microbial chemicals used
    must be ENVIRONMENTAL PROTECTION AGENCY registered for use in HVAC systems.
    Request to see the chemical's Material Safety Information Sheet (MSDS).

    If you are still concerned, call the EPA
    at 1-800-438-4318. There are no EPA registered anti-microbial
    products for use on porous system surfaces -
    such as fiberglass surfaces.

    When sanitizing air ducts you would like to make sure the air duct cleaning firm uses safe; effective EPA approved products that are safe for people,
    pets, and the environment. An atomizer fogs the sanitizing product throughout the whole ventilation system.


    Allergic people, infants and elderly are especially
    sensitive towards the microbes that cause respiratory problems such as
    bacteria, mildew, fungi algae plus dust mites which require a highly-effective
    sanitizer to eliminate odor-causing microorganisms
    as well contaminants associated with allergies, mildew and bacterial growth.
    Make sure the sanitizer can be rated by the EPA as a class IV product
    with the lowest toxicity rating. Sanitizing air ducts indicates toxicity
    and safety safeguards that will establish and ensure there are
    no harmful dermal (skin), ocular (eyes), breathing (breathing) or ingestion (swallowing) results from
    the products.

    There are two popular types of vacuum collection systems...
    those mounted on trucks and trailers versus portable units.
    Truck/trailer mounted machines are generally more powerful than portable tools.
    By contrast, portable equipment often can be brought directly into a facility, picking out the vacuum closer to the ductwork.
    Both types of equipment clean to air flow duct industry standards.
    Vacuum systems should be attached to a collection device to get
    safe containment prior to disposal. Vacuum pressure collection device which exhausts indoors must be HEPA (high
    efficiency particulate arrestance) filtered.

    The frequency associated with air duct (HVAC) cleaning depends on several factors:


    *before occupying a brand new home.
    *afterhome renovations or renovating.
    *number of smokers in the home.
    *Pets that shed hair and dander.
    *Water contamination or damage to the home or HVAC system.

    *Residents with allergies or asthma benefit from better indoor air quality.


    The United States Epa 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, climatic region,
    level of contamination" and type of duct material.

    Consumers ought to beware of air duct cleaning companies making sweeping claims about
    the health advantages of duct cleaning - such claims
    are unsubstantiated.

    Consumers also needs to beware of "blow-and-go"
    air duct cleaning companies that charge low charges and do a
    poor job of cleaning the particular heating and cooling system.
    These companies also try to persuade consumers into
    unneeded solutions or provide service without the customer's permission. Contact
    the Better Business Bureau and local, federal, and condition elected officials to
    report the business.

    Interview at least 3 local surroundings duct
    and HVAC cleaning companies and to perform a free system inspection and to provide a price to clean the particular HVAC system.


    Narrow your listing of potential contractors:

    o Make sure the organization is a member in good standing of the National Air
    Duct Cleaners Association (NADCA).
    o Verify that the company is certified by NADCA to
    perform HVAC system cleaning.
    o Ask how long the company has been in company and determine
    if that experience is adequate.
    o Ask if the company has got the right equipment to effectively carry out cleaning, and if
    the company has done operate homes similar
    to yours. Ask for references from neighbors.
    o Inquire whether or not the company is in good standing using the local Better
    Business Bureau.
    o Get evidence that the company is properly licensed and adequately insured.


    o Be sure that the company is going to clean and
    visually examine all of the air ducts and related system components.

    o Avoid advertisements for "$99 whole house specials"
    along with other sales gimmicks.

    NADCA Members indication a Code of Ethics stating they will do
    everything possible to shield the consumer and to follow NADCA Criteria for air duct cleaning.
    Air flow duct cleaning companies must meet up with stringent requirements.
    All members must have certified Air System Cleaning Specialists (ASCS) on staff, who have used and passed the
    NADCA Qualification Examination. Passing the exam
    shows extensive knowledge in HVAC design and cleaning methodologies.
    Air System Cleaning Specialists are also required to carry on their industry education by going
    to seminars to keep their NADCA accreditation status current.



    Find out as much as you can about the air duct cleaning business before you hire the company.


    *Ask the company to display proof of NADCA membership plus certification?
    *Ask how long has the service provider been in the residential HVAC system cleaning
    business?
    *Ask the service provider provide you with evidence of the
    current Worker's Compensation and General Liability
    Insurance coverage (Ask for Certificate of Insurance)
    *Ask the contractor to display the proper licenses required by your city and condition to perform the
    work they are proposing. (Not all cities or states require licenses)
    *Ask the contractor give you 3 to 5 customer references with phone numbers from air duct
    services offered in the last 30 days?
    *Ask the service provider to conduct a thorough inspection of the system PRIOR
    to performing any work and alert you to any issues. This is required by the current NADCA Assessment, Cleaning & Restoration associated with HVAC Systems (ACR) Standard.


    *Ask the contractor to provide you with the means to conduct a visual inspection anytime
    during the cleaning? (Mirror and flashlight, camera or other remote visual systems.
    )
    *Ask the service provider if it will be cleaning the complete system, including coils and fans?

    *Ask the company if it will actually do the work? (Some companies subcontract the
    work to independent contractors; apply the same hard guidelines for subcontractors as well.
    )
    *Ask the contractor to give you the guaranteed price before the
    inspection. This might expose you to extra costs mainly because finding
    mold in the system, broken fiberglass insulation, cleaning or dealing with cooling coils may become
    add-on costs.

    The amount of time it takes an air flow duct
    cleaning company to clean a residential HVAC system depends on:

    *the size of the home
    *the number of techniques
    *the extent of the contamination
    *the number of HVAC cleaners performing the task

    Ask the 3 HVAC companies you trust the most to inspect your body and give
    you a completion time calculate for your system of how long the job should take;
    as well as all of the steps each contractor plans to
    implement throughout the job.

    Remember, we are breathing countless germ-carrying dust and mold contaminants from air
    ducts that cause allergies, asthma--even terminal illnesses.
    In every homes, the air ducts gather dust, dirt, human skin flakes plus pet dander, becoming holding tissue for allergens, mold spores, germs and
    other contaminants. The problem begins even before you move into a newly-built house, with the buildup of drywall dust, sawdust and other debris in system that provide a
    perfect environment for the development of germs and allergens.
    This problem worsened in the 1970's, as new construction techniques made buildings more tightly sealed,
    which restricts the particular flow of fresh air. Every day, households breathe air that is continually circulated through contaminated ductwork by your HVAC system.
