How you can select an air duct cleaning company?
You can find health advantages for all residents from regularly washing the Heating, Ventilation, Air Cooling (HVAC) System.
Heating, ventilation, and air conditioner (HVAC) systems collect mold, fungi, bacteria and a number of contaminants that reduce the quality of the air residents and visitors breathe. A dirty air duct plays a role in poor indoor air quality and affects the fitness of people in the residence.
The purpose of residential air duct cleaning would be to remove these contaminants from a home’s HVAC system for the best indoor air quality.
The most effective way to clean up an air duct or ventilation system is to apply a specialized, powerful vacuum which puts the air duct / ventilation system under negative pressure. While the vacuum draws air with the system, items are inserted to the ducts to dislodge contaminants and debris from your interior surfaces, moving the contaminants/debris through the home’s air ducts and ventilation systems in to the vacuum.
Vacuum collection alone fails to clean the HVAC system. Brushes, air whips, “skipper balls” and other tools that agitate contaminants and debris scrub the surfaces within the air duct system and propels contaminants and debris in to the vacuum collection device(s).
Anti-microbial chemical sanitizers are applied to the inside surface of the air ducts to manage microbial contamination…but…before sanitizers are employed, the device should be thoroughly cleaned. All anti-microbial chemicals used must be EPA registered to be used in HVAC systems. Ask to see the chemical’s Material Safety Data Sheet (MSDS). In case you are still concerned, call the EPA at 1-800-438-4318. You can find no EPA registered anti-microbial products to be used on porous system surfaces – including fiberglass surfaces.
When sanitizing air ducts you want to ensure the air duct cleaning company uses safe; effective EPA approved products that are secure for individuals, pets, as well as the environment. An atomizer fogs the sanitizing product through the entire ventilation system.
Allergic people, infants and elderly are particularly sensitive to the microbes that induce respiratory problems like bacteria, mildew, fungi algae and dust mites which require a highly-effective sanitizer to eliminate odor-causing microorganisms as well contaminants associated with allergies, mildew and bacterial growth. Ensure the sanitizer is rated from the EPA being a category IV product with the lowest toxicity rating. Sanitizing air ducts means toxicity and safety safeguards that establish and make certain you can find no harmful dermal (skin), ocular (eyes), inhalation (breathing) or ingestion (swallowing) effects from the products.
There are 2 popular varieties of vacuum collection systems…those mounted on trucks and trailers versus portable units. Truck/trailer mounted tools are generally more robust than portable equipment. By contrast, portable equipment often could be brought right into a facility, seeking the vacuum nearer to the ductwork. Both types of equipment clean to air duct industry standards. Vacuum units needs to be mounted on a collection device for safe containment just before disposal. A vacuum collection device which exhausts indoors must be HEPA (high efficiency particulate arrestance) filtered.
The frequency of air duct (HVAC) cleaning is dependent upon several factors:
*before occupying a new home.
*afterhome renovations or remodeling.
*number of smokers within the household.
*Pets that shed hair and dander.
*Water contamination or harm to the home or HVAC system.
*Residents with allergies or asthma reap the benefits of better indoor quality of air.
America Environmental Protection Agency says that “duct cleaning services” typically range in cost from $450 to $1000 per heating and cooling system, depending on the services offered, the dimensions of the system to get cleaned, system accessibility, climatic region, degree of contamination” and kind of duct material.
Consumers should avoid duct cleaning fremont making sweeping claims about the benefits of duct cleaning – such claims are unsubstantiated.
Consumers must also avoid “blow-and-go” air duct cleaning businesses that charge low fees and do a poor job of cleaning the heating and air conditioning system.

o Make sure the clients are a member in good standing from the National Air Duct Cleaners Association (NADCA).
o Verify that this company is certified by NADCA to execute HVAC system cleaning.
o Ask how much time the business has been doing business and find out if that experience is adequate.
o Ask if the business has the right equipment to effectively perform cleaning, and in case the company did work in homes similar to yours. Demand references from neighbors.
o Inquire whether or not the company is in good standing using the local Better Business Bureau.
o Get proof that this company is properly licensed and adequately insured.
o Make sure that the organization will clean and visually inspect all the air ducts and related system components.

Air duct cleaning companies must meet stringent requirements. All members should have certified Air System Cleaning Specialists (ASCS) on staff, who have taken and passed the NADCA Certification Examination.

Extended Equipment Life 9 from 10 system failures are due to dirt and dirt according to the Louisiana Cooperative Extension Service. One of many functions in the fan, located inside your air handler, is to maintain the nvtiuk exchanger cool. Accumulated dirt and debris can reduce the CFM (cubic feet of air a minute) just as much as 50%! Here is the most typical reason behind cracks in heat exchangers. Having your HVAC system cleaned may prevent pre-mature breakdown & aging of your own cooling and heating system.
Reduce Dusting Air duct cleaning reduces household dust by eliminating the dust where it travels most – using your air duct system.
Energy Savings In accordance with the EPA, a buildup of only.042 inches of dirt on the heating coil might result in a decrease of efficiency of 21%. A clean air conveyance system can help to boost efficiency and for that reason may aid in reducing heating and cooling costs.
