Your duct system has never been sealed in Greenbelt. Or it was sealed at installation with standard duct tape that dried and lost adhesion within a few seasons of thermal cycling in Greenbelt, MD. Or you have had the system assessed and been told that duct leakage is contributing to the efficiency and comfort issues you have been experiencing in Greenbelt. You are not dealing with a dramatic failure. No rooms have lost heating entirely. No ducts are visibly disconnected in Greenbelt, MD. But the system is losing conditioned air through dozens of unsealed joints and connections throughout the duct network, and that loss is showing up on every energy bill and in the comfort of every room that is slightly too warm in summer or slightly too cool in winter in Greenbelt.
Duct sealing is the systematic application of correct sealant materials to every joint, connection, and seam in the duct system to eliminate conditioned air loss in Greenbelt, MD. It is a proactive efficiency service rather than a reactive repair in Greenbelt. Where duct leak repair addresses specific active problem leaks that are causing obvious symptoms, duct sealing services address the complete duct system as a comprehensive efficiency improvement in Greenbelt, MD. The goal is to reduce total system leakage to the lowest achievable level across every accessible joint and connection in the system in Greenbelt.

Duct leak repair identifies and addresses specific active problem leaks producing obvious symptoms in Greenbelt. It is a targeted response to identified problems in Greenbelt, MD. Duct sealing services is the systematic sealing of every joint and connection in the complete duct system as a comprehensive efficiency improvement in Greenbelt. It addresses both the obvious leaks and the dozens of smaller unsealed joints that are each losing a small amount of conditioned air that adds up to significant total leakage across the complete system in Greenbelt, MD.
A duct system that was correctly sealed at installation with professional sealant materials maintains its sealing effectiveness for the life of the duct in Greenbelt, MD. The problem is that most residential duct systems were not correctly sealed at installation in Greenbelt. They were assembled with mechanical connections that hold the ducts together but do not seal the gaps at the joint edges in Greenbelt, MD. Whatever initial sealing was applied was often standard duct tape that fails within a few seasons from the temperature cycling that duct systems experience in Greenbelt.
Standard duct tape uses a rubber-based adhesive that performs well at room temperature but dries out and loses adhesion when repeatedly exposed to the temperature extremes that supply ducts experience during HVAC operation in Greenbelt. A supply duct carrying 55-degree air through a 130-degree attic in summer cycles through a 75-degree temperature range with every cooling cycle in Greenbelt, MD. Standard duct tape adhesive is not designed for this cycling and fails within a few seasons of it in Greenbelt. Within three to five years of installation, most standard duct tape on duct joints has failed in Greenbelt, MD.
An individual unsealed duct joint may lose only a small amount of conditioned air in Greenbelt. But a residential duct system has dozens of joints, connections, branch takeoffs, and register boot connections in Greenbelt, MD. The small loss at each unsealed joint accumulates across the complete system to produce the 20 to 30 percent total leakage that the Department of Energy estimates for typical residential duct systems in Greenbelt. Sealing every joint and connection reduces every individual contribution to the total leakage and produces the cumulative improvement that comprehensive sealing delivers in Greenbelt, MD.
Every percentage point of duct leakage eliminated through sealing is a percentage point of conditioned air now reaching the living spaces in Greenbelt, MD. For a home spending $200 per month on heating and cooling with 25 percent duct leakage, sealing that reduces leakage to 10 percent saves approximately $30 per month in Greenbelt. Every month after the sealing service, that saving recurs in Greenbelt, MD.
A room at the end of a long supply run with a dozen unsealed joints may receive significantly less conditioned air than designed in Greenbelt. Sealing every joint in the run ensures each room receives its designed conditioned air volume, reducing the temperature variation between rooms that unsealed duct systems produce in Greenbelt, MD.
Unsealed return duct joints in unconditioned spaces draw air from those spaces into the return airstream in Greenbelt, MD. A return duct in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Greenbelt. Sealing the return duct joints eliminates these unconditioned air pathways in Greenbelt, MD.
Sealing the duct system reduces the load the HVAC operates under in Greenbelt. The system runs shorter cycles, the blower operates at designed parameters, and the cumulative wear rate decreases in Greenbelt, MD.
Air America performs a pre-sealing system assessment and pressure test before any sealing begins in Greenbelt, MD. The pressure test quantifies the total leakage in the system and establishes the baseline for comparing with the post-sealing result in Greenbelt. The system assessment identifies any structural duct damage that requires repair before sealing begins in Greenbelt, MD.
With the system pressurized from the pre-sealing test, Air America technicians systematically work through the accessible duct system to identify every unsealed or inadequately sealed joint, connection, branch takeoff, and register boot connection in Greenbelt, MD. Every identified sealing point is documented before any sealant is applied in Greenbelt.
Air America applies the correct sealant to every identified sealing point throughout the accessible duct system in Greenbelt. Mastic duct sealant for most joint and connection applications in Greenbelt, MD. UL 181-rated foil tape for specific sheet metal seam applications in Greenbelt. The correct sealant for every specific application applied at the correct coverage for a lasting seal in Greenbelt, MD.
Where pressure testing indicates significant leakage beyond what manual sealing of accessible sections can address, Air America provides Aeroseal duct sealing treatment for the inaccessible duct sections in Greenbelt, MD. The Aeroseal process seals leaks from inside the pressurized duct system, reaching sections that cannot be accessed for manual sealant application in Greenbelt.
After all accessible sealing is complete, Air America repeats the pressure test to measure the post-sealing leakage rate in Greenbelt. The before and after measurements document the leakage reduction achieved by the sealing service in Greenbelt, MD. Written documentation provided to the homeowner confirms the service was performed and the improvement achieved in Greenbelt.
Mastic is a water-based sealant specifically formulated for duct system applications in Greenbelt, MD. It remains flexible after curing, maintaining its seal through the expansion and contraction that duct systems experience during thermal cycling in Greenbelt. It does not dry out, crack, or lose adhesion from temperature cycling in Greenbelt, MD. Mastic is the professional standard and the primary material Air America uses on every duct sealing service in Greenbelt.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Greenbelt. It maintains its adhesion through the temperature cycling of duct system operation, unlike standard duct tape whose adhesive fails within a few seasons in Greenbelt, MD. Air America uses it for specific sheet metal seam applications in Greenbelt.
Aeroseal seals joints from inside the duct system in Greenbelt, MD. Aerosolized sealant particles travel with the airstream to leak points where they accumulate and seal the gap in Greenbelt.
