Heating, ventilation and air conditioning (HVAC) collect mold, fungi, bacteria and a variety of contaminants that reduce the quality Air residents and visitors breathe. A dirty air duct contributes to poor air quality inside and affects people's health in the residence.
Collection vacuum alone does not clean the HVAC system. Brushes, air whips, "skipper balls" and other tools that stir contaminants and debris scrub surfaces within the duct system and air contaminants and debris propelled into the device vacuum collection (s).
Anti-microbial chemical disinfectants are applied to the inner surface of air ducts to control contamination microbial … but … before disinfectants are used, the system should be thoroughly cleaned. All anti-microbial chemicals used are be EPA registered for use in HVAC systems. Ask to see the chemical's Material Safety Data Sheet (MSDS). If you're still interested, 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 disinfecting air ducts you want to make sure the cleaning company of air ducts uses safe, effective EPA approved products that are safe for people, pets and the environment. A mist spray the disinfectant through the complete ventilation system.
Allergic people, infants and the elderly are particularly susceptible to bacteria that cause problems as respiratory bacteria, molds, fungi, algae and dust mites that require a very effective disinfectant to eliminate microorganisms causing odors and contaminants associated with allergies, mold and bacterial growth. Make sure the disinfectant is rated by the EPA as a product of class IV with the lowest toxicity rating. Disinfection of air ducts means of toxicity and safety guarantees that establish and ensure that no harmful dermal (skin), ocular (eye) (inhalation breathing) or ingestion (swallowing) the effects of its products.
There are two popular types of collection systems vacuum … those mounted on trucks and trailers from units mobile. Truck / trailer equipment is generally more powerful than portable equipment. However, portable equipment can often be directly in an installation, locate the void closer to the ducts. Both types of equipment to clean air standards driven industry. Units vacuum must be connected to a device for safe collection of containers before disposal. A collection device vacuum exhausts inside must be HEPA (high efficiency particulate arrest) filtered.
The frequency of the air duct (HVAC) cleaning depends on several factors:
* Held before a new home.
* Afterhome renovations or remodeling.
* Number of smokers in the household.
* Pets that shed hair and dander.
* Water contamination or damage to the home or HVAC system.
* Residents with allergies or asthma have a better quality of indoor air.
The United States Environmental Protection Agency says that "duct cleaning services "typically range in cost from $ 450 to $ 1,000 per heating and cooling, depending on the services offered, size of system cleaned, system accessibility, climatic region, the level of contamination "and type of adhesive material.
Consumers must beware of business cleaning air ducts making sweeping claims about the benefits of duct cleaning - such claims are baseless.
Consumers should also beware of "Blow-and-go" business cleaning air ducts that impose costs down and make a bad work cleaning the heating and cooling system. These companies are also trying to convince consumers of unnecessary services or provide services without permission of the consumer. Contact officials of the Better Business Bureau and local, federal and state elected to report the company.
Interview at least 3 HVAC air duct cleaning and local contractors and conduct a free inspection system and provide a price to clean the system HVAC.

* Make sure the company is a member in good standing of the National Air Duct Cleaners Association (NADCA).
* Check that the company is certified by NADCA to perform HVAC system cleaning.
* Ask how long the company in business and determine if this experience is sufficient.
* Ask if the company has the right equipment for the efficient cleaning, and the company has done work in homes similar to yours. Ask for references from neighbors.
* Ask if the company is in good standing with the local Better Business Bureau.
* Get proof that the company is properly licensed and adequately insured.
* Ensure that the company will clean and visually inspect all air ducts and related system components.
* Avoid advertisements for "house specialties, all 99" and other gadgets for sale.
