Are you looking to improve energy savings in your home or business? Aeroseal HVAC air duct sealing is a great way to do just that. But when it comes to sealing air ducts in humid climates like Miami-Dade County (Florida), there are certain considerations that need to be taken into account. In this article, we'll explore the building codes that apply to attic insulation facilities in the area, the importance of looking for manufacturers that offer warranties for their products, and the preventive maintenance program you should follow to minimize duct contamination.Air duct sealing is a process that seals ducts from the inside by applying an industry-leading, non-toxic solution that forms and fills gaps. The EPA does not recommend cleaning air ducts except when necessary due to the uncertainty surrounding the benefits of duct cleaning in most cases.
Duct tape is not a reliable solution for duct problems, so it's important to look for other options.One of the best ways to prevent air ducts from growing is to clean them regularly. Some service providers may suggest applying chemical treatments (sealants or other encapsulants) to encapsulate or cover the inner surfaces of air ducts and equipment housings, as they believe this will control mold growth or prevent the release of dirt particles or fibers from the ducts. Additionally, a chemical biocide may be applied to the inside of the ducts to eliminate bacteria (germs) and fungi (mold) and prevent future biological growth.Manufacturers of products marketed to coat and encapsulate duct surfaces claim that these sealants prevent dust and dirt particles from inside air ducts from being released into the air. If enough dirt and moisture are allowed to enter the duct system, there may not be a significant difference in the speed or extent of microbial growth in internally lined or bare sheet metal ducts.To find companies that offer duct cleaning services, you can consult the section on duct cleaning in the Yellow Pages or contact the National Air Duct Cleaners Association (NADCA).
Cases in which it might be appropriate to use sealants to encapsulate duct surfaces include repairing damaged fiberglass insulation or combating fire damage to ducts.
