Do return air ducts need to be sealed?

Return air ducts must be sealed and unobstructed. Sealing return air ducts is just as important as sealing supply ducts. Sealing all the connections of the duct sections with putty, a specialized gummy sealant or metal tape prevents air leaks. Sealing can prevent it from “backing up”.

This occurs when flue gases, such as carbon monoxide, from gas appliances, such as water heaters, dryers and ovens, return to the living space, rather than being expelled to the outside. If you properly seal the air ducts, their normal operation can minimize this risk. If the system's air ducts are properly sealed, common comfort problems can be solved, such as a room being too hot in summer or too cold in winter. Aeroseal is a product that is sprayed into the duct system and basically adheres to the interior to completely seal the return air ducts.

Sealed air ducts maintain a comfortable living environment throughout the house for you and your family. You should schedule regular maintenance visits with your local professional and ask about how to adjust the unit's air ducts. You can do this structurally and mechanically, trying to reach each of these ducts and try to repair them so they don't leak. Contaminants can enter ducts through inadequate seals and cause health problems, such as asthma or outdoor allergies.

If the air ducts in your home are not properly and hermetically sealed, the air conditioner may escape to areas of your home where it is not needed. When homeowners choose to install a distributed heating and cooling system, it works through an air duct system. The entire air conditioning unit is less likely to be damaged, corroded, or fall off your appliance if it has a properly sealed air duct, which must also be maintained through regular checks by a local professional. In addition to worrying about damage to the wallet, unsealed air ducts could lead to poor indoor air quality.

By sealing HVAC ducts in both return and return pipes, you can save money and improve the comfort of your home.
