How to choose an air duct cleaning company?
Regular cleaning of the heating, ventilation and air conditioning (HVAC) system brings health benefits to all residents.
Heating, ventilation, and air conditioning (HVAC) systems collect mold, fungus, bacteria, and a variety of contaminants that affect the quality of the air that residents and visitors breathe. A dirty air duct contributes to poor indoor air quality and affects the health of the people in the home.
The purpose of cleaning air ducts in living spaces is to remove these contaminants from a home’s HVAC system in order to maintain the best indoor air quality.
The most effective way to clean an air duct and / or ventilation system is to use a special, powerful vacuum that puts the air duct / ventilation system under negative pressure. As the vacuum cleaner draws air through the system, devices are inserted into the ducts to remove debris and debris from the interior surfaces and to move the debris / debris from the home’s air ducts and ventilation systems into the vacuum cleaner.
Vacuum collection alone does not clean the HVAC system. Brushes, air whips, “skipper balls”, and other tools that stir up debris and debris scrub the surfaces within the air duct system, throwing debris and debris into the vacuum collection device (s).
Antimicrobial chemical disinfectants are applied to the inner surface of the air ducts to control microbial contamination … but … before using disinfectants, the system should be thoroughly cleaned. All antimicrobial chemicals used must be EPA registered for use in HVAC systems. Obtain the Material Safety Data Sheet (MSDS) for the chemical. If you still have concerns, call the EPA at 1-800-438-4318. There are no EPA registered antimicrobial products for use on porous system surfaces – such as B. fiberglass surfaces.
When disinfecting air ducts, you want to make sure that the air duct cleaning company is using it safely; effective, EPA approved products that are safe for people, pets and the environment. An atomizer nebulises the disinfectant product throughout the ventilation system.
Allergy sufferers, infants and the elderly are particularly sensitive to microbes that cause respiratory problems, such as bacteria, powdery mildew, fungal algae and house dust mites, which require a highly effective disinfectant to remove odor-causing microorganisms and contaminants related to allergies, mold and bacterial growth. Make sure the disinfectant has been rated by the EPA as a Category IV product with the lowest toxicity rating. Disinfecting air ducts implies toxicity and safety precautions that ensure and ensure that the products do not have any harmful effects on the skin (skin), eye (eyes), inhalation (breathing) or ingestion (swallowing).
There are two common types of vacuum collection systems … those that are truck and trailer mounted versus portable units. Truck / trailer mounted devices are generally more powerful than portable devices. In contrast, portable devices can often be brought directly into a facility, placing the vacuum closer to the ducts. Both types of devices are clean according to industry standards for air ducts. Vacuum units should be connected to a collection facility for safe containment prior to disposal. A vacuum collection device that sucks indoors must be HEPA (High Efficiency Particulate Arrestance) filtered.
The frequency of cleaning air ducts (HVAC) depends on several factors:
- before moving into a new home.
- After home renovations or remodeling.
- Number of smokers in the household.
- Pets that lose hair and flakes of skin.
- Water contamination or damage to the home or HVAC system.
- Residents with allergies or asthma benefit from better indoor air quality.
The US Environmental Protection Agency says that the cost of “sewer cleaning services” is typically between $ 450 and $ 1000 per heating and cooling system, depending on the services offered, the size of the system being cleaned, the system accessibility, the climatic region, the degree of pollution “and the type of duct material.
Consumers should beware of air duct cleaning Asheville companies who make blanket claims about the health benefits of duct cleaning – such claims are unfounded.
Consumers should also beware of “blow-and-go” duct cleaning companies that offer low rates
