Professional Duct Sealing Services in Des Moines, WA

Your duct system has never been sealed in Des Moines. Or it was sealed at installation with standard duct tape that dried and lost adhesion within a few seasons of thermal cycling in Des Moines, WA. 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 Des Moines. You are not dealing with a dramatic failure. No rooms have lost heating entirely. No ducts are visibly disconnected in Des Moines, WA. 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 Des Moines.

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 Des Moines, WA. It is a proactive efficiency service rather than a reactive repair in Des Moines. 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 Des Moines, WA. The goal is to reduce total system leakage to the lowest achievable level across every accessible joint and connection in the system in Des Moines.

Air America provides complete duct sealing services throughout Des Moines in Des Moines, WA. Pressure testing before sealing to establish the baseline leakage level in Des Moines. Systematic sealing of every accessible joint and connection with correct sealant materials in Des Moines, WA. Aeroseal treatment for inaccessible sections where the leakage warrants it in Des Moines. Pressure testing after sealing to document the improvement with measured numbers in Des Moines, WA. And a guarantee on every sealing service in Des Moines. Call now, we respond fast in Des Moines, WA.

Why Duct Sealing Is Different From Duct Leak Repair in Des Moines, WA

Duct leak repair identifies and addresses specific active problem leaks producing obvious symptoms in Des Moines. It is a targeted response to identified problems in Des Moines, WA. Duct sealing services is the systematic sealing of every joint and connection in the complete duct system as a comprehensive efficiency improvement in Des Moines. 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 Des Moines, WA.

Why Every Duct System Needs Sealing

Why Every Residential Duct System Needs Sealing in Des Moines, WA

How Duct Systems Lose Their Sealing Over Time in Des Moines

A duct system that was correctly sealed at installation with professional sealant materials maintains its sealing effectiveness for the life of the duct in Des Moines, WA. The problem is that most residential duct systems were not correctly sealed at installation in Des Moines. They were assembled with mechanical connections that hold the ducts together but do not seal the gaps at the joint edges in Des Moines, WA. 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 Des Moines.

Why Standard Duct Tape Doesn't Last in Des Moines, WA

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 Des Moines. 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 Des Moines, WA. Standard duct tape adhesive is not designed for this cycling and fails within a few seasons of it in Des Moines. Within three to five years of installation, most standard duct tape on duct joints has failed in Des Moines, WA.

The Cumulative Effect of Unsealed Joints Throughout the System in Des Moines, WA

An individual unsealed duct joint may lose only a small amount of conditioned air in Des Moines. But a residential duct system has dozens of joints, connections, branch takeoffs, and register boot connections in Des Moines, WA. 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 Des Moines. Sealing every joint and connection reduces every individual contribution to the total leakage and produces the cumulative improvement that comprehensive sealing delivers in Des Moines, WA.

What Sealing Improves

What Duct Sealing Services Improve in Your Home in Des Moines, WA

Energy Efficiency and Lower Monthly Bills in Des Moines

Every percentage point of duct leakage eliminated through sealing is a percentage point of conditioned air now reaching the living spaces in Des Moines, WA. 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 Des Moines. Every month after the sealing service, that saving recurs in Des Moines, WA.

Even Temperature Distribution Throughout Every Room in Des Moines, WA

A room at the end of a long supply run with a dozen unsealed joints may receive significantly less conditioned air than designed in Des Moines. 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 Des Moines, WA.

Improved Indoor Air Quality From Return Duct Sealing in Des Moines

Unsealed return duct joints in unconditioned spaces draw air from those spaces into the return airstream in Des Moines, WA. A return duct in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Des Moines. Sealing the return duct joints eliminates these unconditioned air pathways in Des Moines, WA.

Reduced HVAC Equipment Strain and Extended Equipment Life in Des Moines, WA

Sealing the duct system reduces the load the HVAC operates under in Des Moines. The system runs shorter cycles, the blower operates at designed parameters, and the cumulative wear rate decreases in Des Moines, WA.

Our Sealing Process

Air America's Duct Sealing Process in Des Moines, WA

1

Pre-Sealing System Assessment and Pressure Test in Des Moines

Air America performs a pre-sealing system assessment and pressure test before any sealing begins in Des Moines, WA. The pressure test quantifies the total leakage in the system and establishes the baseline for comparing with the post-sealing result in Des Moines. The system assessment identifies any structural duct damage that requires repair before sealing begins in Des Moines, WA.

2

Every Joint and Connection Identified for Sealing in Des Moines

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 Des Moines, WA. Every identified sealing point is documented before any sealant is applied in Des Moines.

3

Correct Sealant Applied to Every Joint in Des Moines, WA

4

Aeroseal Treatment for Inaccessible Sections Where Needed in Des Moines

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 Des Moines, WA. The Aeroseal process seals leaks from inside the pressurized duct system, reaching sections that cannot be accessed for manual sealant application in Des Moines.

5

Post-Sealing Pressure Test and Documentation in Des Moines, WA

After all accessible sealing is complete, Air America repeats the pressure test to measure the post-sealing leakage rate in Des Moines. The before and after measurements document the leakage reduction achieved by the sealing service in Des Moines, WA. Written documentation provided to the homeowner confirms the service was performed and the improvement achieved in Des Moines.

Sealing vs Repair

Duct Sealing vs Duct Leak Repair — Understanding the Difference in Des Moines, WA

Duct Leak Repair in Des Moines

A targeted response to specific active problem leaks causing obvious symptoms in Des Moines, WA. A room that has recently lost heating because of a disconnected duct section. A comfort problem that has developed noticeably and recently in Des Moines. Finds the specific leaks causing the specific symptoms and fixes them in Des Moines, WA.

Duct Sealing Services in Des Moines, WA

The complete duct system addressed as a comprehensive efficiency improvement in Des Moines. Not just the obvious active leaks. Every joint, every connection, every branch takeoff, and every register boot connection throughout the accessible system in Des Moines, WA. The goal is the lowest achievable total leakage across the complete system in Des Moines.

Many duct systems with significant leakage have both structural faults and leaking joints in Des Moines, WA.

FAQ

Duct Sealing Services FAQs in Des Moines, WA

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 Des Moines. It reduces total system leakage, delivering more of the conditioned air the HVAC produces to the living spaces in Des Moines, WA. The result is lower energy bills, more even temperatures throughout the home, and improved indoor air quality in Des Moines.
The clearest indicators in Des Moines are energy bills that seem high relative to your usage, rooms that consistently will not quite reach the right temperature, an HVAC system that runs longer than seems necessary, higher than expected dust levels in the home, and humidity problems during cooling season in Des Moines, WA. Pressure testing is the definitive way to quantify the leakage in your specific system in Des Moines.
Duct leak repair is a targeted response to specific active problem leaks causing obvious symptoms in Des Moines. Duct sealing services address the complete duct system as a comprehensive efficiency improvement, sealing every joint and connection throughout the accessible system in Des Moines, WA. Duct sealing addresses both obvious active leaks and the many smaller unsealed joints that collectively produce significant total leakage in Des Moines.
Mastic duct sealant is the professional standard for most duct joint and connection applications in Des Moines. It remains flexible after curing and maintains its seal through the thermal cycling that duct systems experience during HVAC operation in Des Moines, WA. UL 181-rated foil tape is appropriate for specific sheet metal seam applications in Des Moines. Standard duct tape is not appropriate for any duct sealing application because its adhesive fails within a few seasons of thermal cycling in Des Moines, WA.
Mastic duct sealant maintains its sealing effectiveness for the life of the duct system when correctly applied in Des Moines. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Des Moines, WA. Both materials significantly outlast standard duct tape in Des Moines.
Yes. Sealing the duct system reduces the conditioned air loss the HVAC was experiencing and delivers more of the conditioned air it produces to the living spaces in Des Moines. The reduction in leakage translates directly to reduced energy consumption for the same heating and cooling output in Des Moines, WA.
Duct cleaning before duct sealing allows the mastic sealant to bond to clean duct surfaces in Des Moines. Applying mastic to duct surfaces coated with accumulated dust and debris reduces the bond quality and long-term effectiveness of the seal in Des Moines, WA. Air America recommends cleaning before sealing when both services are needed and can coordinate both in a single visit in Des Moines.
Yes in several ways in Des Moines. Sealing return duct leaks in crawl spaces eliminates the pathway through which crawl space moisture enters the circulated air in Des Moines, WA. Reducing supply duct leakage increases the volume of conditioned air reaching the living spaces, allowing the air conditioner to run longer cycles that remove more humidity per cycle in Des Moines.
Aeroseal is a duct sealing technology that seals leaks from inside the pressurized duct system in Des Moines. Aerosolized sealant particles travel to leak points and seal the gaps in Des Moines, WA. It is the right choice when significant leakage exists in duct sections that cannot be physically accessed for manual sealant application in Des Moines.
A complete duct sealing service for a standard residential system typically takes four to six hours including pre-sealing pressure testing, systematic sealant application, and post-sealing pressure testing in Des Moines. Larger systems with more duct runs and joint points take longer in Des Moines, WA.
Duct sealing service costs in Des Moines range from $300 to $600 for smaller systems, $500 to $1,000 for standard residential systems, $800 to $1,500 and above for larger systems, and $1,500 to $3,000 and above for systems requiring Aeroseal treatment in Des Moines, WA. All pricing confirmed upfront before work begins in Des Moines.
Yes. Every Air America duct sealing service is guaranteed in Des Moines. If the sealing does not produce the expected improvement within the guarantee period, we return and address it at no additional charge in Des Moines, WA.
