Return air ducts are an essential component of any home's heating and cooling system. To ensure that the system works efficiently, it is just as important to seal the ducts as it is to seal the supply lines. Putty, a specialized rubber sealant, or metal tape should be used for this purpose. Building cavities should never be used as return lines, and nail compartments or cavities should also be avoided.
Coated floor beams should not be used either. If the floor joists are inspected and the cavities of the uprights are utilized as return elements, air leaks can occur in the returns and negative pressure fields can be created in the interstitial spaces. When building cavities are employed as return ducts, dust spots on carpet baseboards, odor problems, mold and contaminant transport issues can also arise. Structurally and mechanically, it is possible to access each of these ducts and attempt to repair them so that they don't leak. Unsealed air ducts can lead to poor indoor air quality, as contaminants can enter through poor-quality seals and cause health problems such as asthma or outdoor allergies. If the air ducts in your system are properly sealed, you can solve the most common comfort problems. A correctly sealed air duct also means that the entire air conditioning unit is less likely to be damaged, corroded, or fall out of its installation.
Regular maintenance visits by a local professional should be scheduled to check on how to adjust the unit's air ducts. Aeroseal is a product that is sprayed into the duct system and adheres to the interior to completely seal the air return ducts. The joints, joints and openings of the air treatment system, of the furnace or of the ducts close to the air treatment system or to the furnace must be sealed with both fiberglass mesh and putty due to increased local vibration and bending. When homeowners opt for a distributed heating and cooling system, it works through an air duct system. If your home's air ducts aren't properly and hermetically sealed, the air conditioner may leak to areas of the house where it's not needed. When using flexible ducts, care must be taken to avoid restricting airflow, such as those that occur when the ducts are pinched or bent when bent into a narrow radius.
By sealing air conditioning vents in both the vent and return lines, you can save money and improve the comfort of your home. Sealed air vents maintain a comfortable living environment throughout the home for you and your family.
