Should You Have the Air Ducts in Your Home Cleaned?
A lot of people are now conscious that indoor air pollution is an situation of developing concern and increased visibility. Quite a few businesses are advertising goods and services intended to improve the quality of your indoor air. You have likely noticed an advertisement, received a coupon inside the mail, or been approached straight by a firm offering to clean your air ducts as a means of enhancing your home’s indoor air high-quality. These services typically – but not normally – variety in cost from $450 to $1,000 per heating and cooling program, based on:
the solutions provided
the size of your system to be cleaned
level of contamination
When you determine to possess your heating and cooling system cleaned, it essential to make confident the service provider agrees to clean all elements of the program and is certified to perform so.
Duct cleaning generally refers towards the cleaning of several heating and cooling technique components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, as well as the air handling unit housing (See diagram).
If not effectively installed, maintained and operated, these components may perhaps become contaminated with particles of dust, pollen or other debris. If moisture is present, the prospective for microbiological growth (e.g., mold) is improved and spores from such development may be released into the home’s living space. A few of these contaminants may possibly result in allergic reactions or other symptoms in folks if they are exposed to them. In the event you determine to possess your heating and cooling program cleaned, it can be essential to make confident the service provider agrees to clean all components on the program and is certified to complete so. Failure to clean a element of a contaminated technique can outcome in re-contamination from the entire program, hence negating any possible rewards. Approaches of duct cleaning vary, despite the fact that requirements have already been established by sector associations concerned with air duct cleaning. Ordinarily, a service provider will use specialized tools to dislodge dirt and also other debris in ducts, then vacuum them out with a high-powered vacuum cleaner.
Furthermore, the service provider may possibly propose applying chemical biocides, developed to kill microbiological contaminants, towards the inside on the duct perform and to other method components. Some service providers might also suggest applying chemical remedies (sealants or other encapsulants) to encapsulate or cover the inside surfaces on the air ducts and gear housings because they think it’ll manage mold growth or avert the release of dirt particles or fibers from ducts. These practices have however to be completely researched and also you must be totally informed ahead of deciding to permit the usage of biocides or chemical therapies in your air ducts. They must only be applied, if at all, right after the technique has been appropriately cleaned of all visible dust or debris.
Note: Use of sealants to encapsulate the inside surfaces of ducts can be a different practice than sealing duct air leaks. Sealing duct air leaks might help save energy on heating and cooling bills. For more details, see EPA’s Power Star web page.
