What is Duct Sealing?

Duct Sealing is a service in which we remove the duct work from your air conditioner, apply a high velocity mastic sealant, reinforced with fiberglass mesh, reattach the duct work using high tension strapping, and secure the insulation around each duct. Then we seal all seams where the air handler meets the supply plenum and return plenum. Furthermore, we endure that all duct work is properly strapped and ensure there are no sags in the duct runs.

Why is Duct Sealing Important?

Duct Sealing is important for several reasons. Ever wonder why people have their duct work cleaned regularly? Because duct work is very “leaky” and these leaks allow unfiltered air and attic debris such as insulation and dirt to infiltrate the system. This is also primarily why the evaporator coil gets dirty. It’s actually very senseless to have duct work cleaned and leave the system unsealed to become recontaminated. Another very important reason is that these leaks literally equate to dollars being wasted on conditioned air leaking into the attic. The list of benefits could go on, but these are the primary reasons duct sealing is important.

How Often Should My Duct Work Be Sealed?

Aside from having components replaced, if the duct work is correctly sealed, this should last fifteen to twenty years before they should be resealed.
