There are health benefits derived from regularly cleaning our HVAC (or High Voltage Alternating Current) Systems and its air ducts.
It is a fact that heating and air conditioning systems that we use affect the quality of air that we breathe and these systems collect molds, fungi, bacteria and other contaminants. One factor which affects our health is the indoor air quality we breathe indoors, which can be greatly affected by the condition of our air ducts. People with allergies, infants and elderly people who have respiratory problems are best protected with sanitizers that eliminate these microorganisms that contaminate the air. We need to have our air duct cleaned so that the contaminants that have settled in our HVAC systems will be removed and the quality of the air we breathe is pure.
The best way of cleaning an air duct system is to use a particular kind of power vacuum that puts the air duct system under negative pressure. While the vacuum is drawing air through the system, other devices are inserted inside the air duct so that the debris and other contaminants are swept away from the air duct towards the vacuum. Aside from the vacuum, it is necessary to have other materials like brushes, whips, “skipper balls” and other tools to help dislodge debris and contaminants and thus propel them into the vacuum collection devices. When sanitizing air ducts, find out if the company your have hired from the site at machadoair.com are using safe, EPA approved products so that we can be sure that we, our pets, and our environment, are protected Using an atomizer helps to fog the sanitizing product throughout the ventilation system.
The US EPA pegs the cost of duct cleaning service ranging from $450 to $1000 depending on the following factors: services they offer, size of the system to be cleaned, system accessibility, climatic region, level of contamination, and type of duct material.
There are companies which we call “blow-and-go” duct cleaning companies that we should beware of because they render poor quality air duct cleaning services though they charge very low fees. These companies also try to convince customers to make them do other jobs or else they do some extra services that you did not allow. Make sure that the company that you have taken is a member of and in good standing with the National Air Duct Cleaners Association.
