Pressure tested before sealing to quantify the leakage. Every leak point identified and sealed with correct materials. Pressure tested after to confirm measured improvement. Guaranteed.

Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Travelers Rest. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Travelers Rest, SC. Maybe you have even been told your HVAC system is undersized and needs to be replaced in Travelers Rest. Before you spend money on a larger system, consider what happens when a correctly sized system is running against a duct network that is losing 20 to 30 percent of its conditioned air through unsealed joints and connections in Travelers Rest, SC. The system appears undersized because it is losing a significant portion of what it produces before that conditioned air reaches the rooms in Travelers Rest. A new system with the same leaky ducts loses the same percentage and produces the same disappointing results in Travelers Rest, SC.

Duct leakage is the loss of conditioned air through gaps, holes, and unsealed joints in the duct system in Travelers Rest. It happens at every unsealed duct joint, at every connection between duct sections, at branch takeoffs and splitter boxes, and at the connections where duct registers meet the boot at the ceiling or floor in Travelers Rest, SC. In most residential duct systems, these joints were installed with mechanical connections and no sealant, or with standard duct tape that dries, cracks, and loses adhesion within a few seasons of thermal cycling in Travelers Rest. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Travelers Rest, SC. For a home spending $200 per month on heating and cooling, that is $40 to $60 per month delivered to the attic or crawl space rather than to the living spaces in Travelers Rest.

Professional Duct Sealing in Travelers Rest, SC

Duct sealing is the application of correct sealant materials to every unsealed joint, connection, and seam in the duct system to eliminate conditioned air loss in Travelers Rest. It is a different service from ductwork repair in Travelers Rest, SC. Ductwork repair addresses physical structural damage to the duct system. Duct sealing addresses air leakage through the joints and connections of a structurally sound duct system in Travelers Rest. A duct system can be structurally intact with no disconnections, no torn flexible duct, and no collapsed sections, and still lose 20 to 30 percent of conditioned air through unsealed joints in Travelers Rest, SC. That is the problem duct sealing addresses in Travelers Rest.

What Duct Sealing Is and What It Addresses in Travelers Rest, SC

Duct sealing is the process of identifying and sealing every air leakage point in the duct system in Travelers Rest. It addresses the conditioned air loss that occurs through gaps and unsealed connections throughout the duct network in Travelers Rest, SC. The result is a duct system that delivers more of the conditioned air the HVAC produces to the rooms it is intended to reach, reducing energy consumption, improving comfort, and in the case of return duct leakage, improving indoor air quality in Travelers Rest.

Why Duct Sealing Is Distinct From Ductwork Repair in Travelers Rest, SC

Ductwork repair addresses physical structural faults including disconnected sections, torn flexible duct, and collapsed runs in Travelers Rest. Duct sealing addresses air leakage through the joints and connections of a structurally sound system in Travelers Rest, SC. A system may need repair for structural faults, sealing for joint leakage, or both in Travelers Rest. ISA Air Duct assesses the specific condition of the system and recommends the correct service for what is actually found in Travelers Rest, SC.

What ISA Air Duct's Sealing Service Covers in Travelers Rest

ISA Air Duct's duct sealing service covers pre-sealing pressure testing to quantify the leakage, systematic identification of every leak point through the accessible duct system, application of correct sealant materials to every identified leak point, and post-sealing pressure testing to confirm and quantify the improvement in Travelers Rest, SC. Complete sealing of every accessible joint and connection in the system in Travelers Rest.

Where Leakage Occurs

Where Duct Leakage Occurs and Why It Develops in Travelers Rest, SC

At Duct Joints and Connections in Travelers Rest

Every point where two duct sections connect is a potential leakage point in Travelers Rest, SC. In sheet metal duct systems, the longitudinal seams in individual duct sections and the transverse joints where sections connect are leakage sources if not sealed with mastic or appropriate tape in Travelers Rest. In most residential installations, these joints were mechanically connected without sealant in Travelers Rest, SC. The gaps at the joint edges allow conditioned air to escape into the surrounding space with every HVAC cycle in Travelers Rest.

At Branch Takeoffs and Splitter Boxes in Travelers Rest, SC

Branch takeoffs are the fittings that split conditioned air from the main trunk line to the individual branch duct runs in Travelers Rest. They are connection points with multiple edges and angles that are particularly prone to leakage if not correctly sealed in Travelers Rest, SC. Splitter boxes in zoned systems have multiple connection points that represent significant potential leakage area in Travelers Rest. ISA Air Duct pays specific attention to branch takeoffs and splitter boxes during leak identification because they represent some of the largest individual leakage points in typical residential systems in Travelers Rest, SC.

At Register Boot Connections in Travelers Rest

The register boot is the fitting that connects the branch duct run to the floor, ceiling, or wall opening where the register grille mounts in Travelers Rest, SC. The connection between the flexible duct and the boot collar and the connection between the boot and the surrounding framing are both common leakage points in Travelers Rest. Conditioned air escaping at the boot level leaks into the wall or floor cavity rather than through the register into the room in Travelers Rest, SC.

In Flexible Duct Collar Connections in Travelers Rest, SC

Flexible duct connects to sheet metal fittings, boot collars, and plenum connections using a mechanical connection where the flexible duct liner and outer jacket are secured to the fitting with zip ties or straps in Travelers Rest. Without mastic sealant applied to the connection before securing, the connection leaks at the gaps between the duct liner and the fitting surface in Travelers Rest, SC. Mastic sealing of flexible duct collar connections is a standard component of ISA Air Duct's sealing service in Travelers Rest.

Why Leakage Develops in Systems That Were Initially Sealed in Travelers Rest

Systems that were initially sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion in Travelers Rest, SC. Standard duct tape is not rated for the temperature cycling that duct systems experience during normal operation in Travelers Rest. Within a few seasons, standard duct tape on duct joints fails and the underlying joint gap opens to leakage again in Travelers Rest, SC. Mastic sealant and UL 181-rated foil tape are the materials that maintain their sealing effectiveness through the thermal cycling of long-term HVAC operation in Travelers Rest.

What Leakage Costs You

What Duct Leakage Costs You Every Month in Travelers Rest, SC

20–30%
Conditioned air lost through leakage in typical residential systems (DOE estimate)
$40–$60
Per month wasted for a $200/mo heating & cooling budget at 25% leakage
$600–$900
Annual wasted energy spending at 25% leakage for $200–$300/mo budgets
18–36
Months to payback for a $500–$1,000 sealing service through energy savings

The Department of Energy's Estimate on Residential Duct Losses in Travelers Rest, SC

The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leaks, holes, and poorly connected ducts before that air reaches the living spaces in Travelers Rest. This estimate is based on testing of real residential duct systems across a range of ages and construction types in Travelers Rest, SC. In systems with particularly poor initial installation or significant seal failure, the loss can be higher in Travelers Rest.

How Leakage Causes Uneven Heating and Cooling in Travelers Rest, SC

Supply duct leakage in the spaces between branch duct connections and the registers means the rooms furthest from the air handler receive less conditioned air than they were designed to receive in Travelers Rest. The conditioned air that leaks out of the supply duct before reaching the register is air that does not reach the room in Travelers Rest, SC. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in Travelers Rest. The room that is always too hot in summer and too cold in winter is often a room at the end of a leaky supply run in Travelers Rest, SC.

What Return Duct Leakage Does to Indoor Air Quality in Travelers Rest

Return duct leakage draws air from the surrounding space into the return airstream in Travelers Rest, SC. In an attic, that means drawing hot, dusty attic air into the air handler in summer in Travelers Rest. In a crawl space, that means drawing crawl space air including moisture, mold spores, and whatever else is in the crawl space environment into the system and distributing it throughout the home in Travelers Rest, SC. Return duct sealing eliminates this pathway and keeps the circulated air to what is drawn from the living spaces in Travelers Rest.

The Hidden Equipment Cost of Running a Leaky Duct System in Travelers Rest, SC

An HVAC system compensating for duct leakage losses runs longer cycles, works against the pressure imbalance that leakage creates in the duct system, and conditions more total air volume than the living space requires in Travelers Rest. The cumulative effect is accelerated component wear across the blower motor and other system components in Travelers Rest, SC. Sealing the duct system reduces the load the HVAC operates under and extends the equipment service life in Travelers Rest.

How We Seal Your System

How ISA Air Duct Finds and Seals Every Leak Point in Travelers Rest, SC

1

Duct System Pressure Testing — Quantifying the Leakage in Travelers Rest

ISA Air Duct performs duct system pressure testing before sealing to quantify the total leakage in the system in Travelers Rest, SC. A calibrated fan is connected to the duct system and the system is pressurized to a standard test pressure in Travelers Rest. The airflow required to maintain that pressure is measured in Travelers Rest, SC. The measured airflow represents the total leakage rate of the system and provides the baseline for comparing before and after sealing performance in Travelers Rest.

2

Leak Location — Finding Every Specific Leak Point in Travelers Rest, SC

With the system pressurized, ISA Air Duct technicians systematically locate every specific leak point in the accessible duct system in Travelers Rest. A pressurized leaking duct system produces audible air movement and detectable airflow at leak points that can be located systematically in Travelers Rest, SC. Every identified leak point is marked for sealing in Travelers Rest.

3

Correct Sealant for the Specific Joint Type in Travelers Rest

ISA Air Duct selects the correct sealant for each specific leak point based on the duct type, the joint configuration, and the access conditions in Travelers Rest, SC. Mastic duct sealant for most duct joints and connections in Travelers Rest. UL 181-rated foil tape for specific sheet metal seam applications in Travelers Rest, SC. The correct material for the specific application in Travelers Rest.

4

Systematic Sealing of Every Identified Leak Point in Travelers Rest, SC

ISA Air Duct systematically seals every identified leak point in the accessible duct system in Travelers Rest. Mastic applied at the correct thickness to cover the full joint gap and bond to the duct surfaces on both sides in Travelers Rest, SC. UL 181-rated tape applied with adequate overlap and firm pressure for full adhesion in Travelers Rest. Every leak point addressed before the post-sealing test in Travelers Rest, SC.

5

Post-Sealing Pressure Test — Confirming the Improvement in Travelers Rest

After sealing is complete, ISA Air Duct repeats the pressure test to measure the post-sealing leakage rate in Travelers Rest, SC. The before and after measurements quantify the leakage reduction achieved by the sealing in Travelers Rest. The post-sealing test confirms the sealing produced meaningful improvement and provides documented evidence of the result in Travelers Rest, SC.

Sealant Materials

What ISA Air Duct Uses to Seal Duct Leaks in Travelers Rest, SC

Mastic Duct Sealant — The Correct Choice for Most Applications in Travelers Rest

Mastic is a water-based sealant specifically formulated for duct system applications in Travelers Rest, SC. It remains flexible after curing, which means it maintains its seal through the expansion and contraction that duct systems experience during thermal cycling in Travelers Rest. It bonds well to sheet metal, flexible duct liners, and fibrous duct board in Travelers Rest, SC. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Travelers Rest. Mastic is the correct sealant for most duct joint applications and the material ISA Air Duct uses on the majority of duct sealing work in Travelers Rest, SC.

UL 181-Rated Foil Tape — For Specific Seam Applications in Travelers Rest, SC

UL 181-rated foil tape is a pressure-sensitive tape specifically tested and rated for HVAC duct applications in Travelers Rest. Unlike standard duct tape, UL 181 foil tape maintains its adhesion through the temperature cycling of duct system operation in Travelers Rest, SC. It is appropriate for specific sheet metal seam applications where a clean, smooth seal is needed in Travelers Rest. ISA Air Duct uses UL 181-rated foil tape where its specific properties make it the correct choice for the application in Travelers Rest, SC.

Why Standard Duct Tape Is Never Used in Travelers Rest

Standard silver duct tape is not rated for duct system applications in Travelers Rest, SC. Its rubber-based adhesive dries and loses adhesion from the temperature cycling that duct systems experience during normal operation in Travelers Rest. Standard duct tape on duct joints fails within a few heating and cooling seasons in Travelers Rest, SC. Joints sealed with standard duct tape appear sealed when the tape is first applied and are open to leakage again within a few years in Travelers Rest. ISA Air Duct never uses standard duct tape for duct sealing work in Travelers Rest, SC.

Aeroseal Duct Sealing for Inaccessible Ducts in Travelers Rest, SC

Aeroseal is a duct sealing technology that seals leaks from the inside of the duct system in Travelers Rest. Aerosolized sealant particles are introduced into the pressurized duct system and travel with the airstream to leak points where they accumulate and seal the gap in Travelers Rest, SC. Aeroseal is particularly effective for sealing leaks in inaccessible duct sections that cannot be reached for manual sealant application in Travelers Rest. ISA Air Duct provides information on Aeroseal duct sealing for systems where inaccessible duct sections represent significant leakage that manual sealing cannot address in Travelers Rest, SC.

FAQ

Duct Sealing FAQs in Travelers Rest, SC

Duct sealing is the application of correct sealant materials to every unsealed joint, connection, and seam in the duct system to eliminate conditioned air loss in Travelers Rest. It matters because the Department of Energy estimates typical residential duct systems lose 20 to 30 percent of conditioned air through leakage before it reaches the living spaces in Travelers Rest, SC. That loss is paid for on every energy bill and experienced as comfort problems in every room the leaky ducts fail to serve correctly in Travelers Rest.
The clearest indicators in Travelers Rest are energy bills that seem high relative to your usage, rooms that consistently will not reach the right temperature, an HVAC system that runs continuously without achieving setpoint, higher than expected dust levels in the home, and humidity problems that seem to come from the HVAC system in Travelers Rest, SC. Pressure testing by a professional is the definitive way to quantify the leakage in your specific system in Travelers Rest.
A duct leakage test connects a calibrated fan to the duct system and pressurizes it to a standard test pressure in Travelers Rest. The airflow required to maintain that pressure is measured in Travelers Rest, SC. The measured airflow represents the total leakage rate of the system and is typically expressed as a percentage of the total system airflow in Travelers Rest. ISA Air Duct performs pressure testing before and after every duct sealing service in Travelers Rest, SC.
Ductwork repair addresses physical structural damage including disconnected sections, torn flexible duct, and collapsed runs in Travelers Rest. Duct sealing addresses air leakage through the joints and connections of a structurally sound system in Travelers Rest, SC. A system may need both repair and sealing, or one without the other, depending on its specific condition in Travelers Rest.
Mastic is a water-based sealant specifically formulated for duct system applications in Travelers Rest. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience during operation in Travelers Rest, SC. Standard duct tape uses a rubber-based adhesive that dries and loses adhesion from temperature cycling, failing within a few seasons in Travelers Rest. Mastic does not dry out, crack, or lose adhesion from temperature cycling in Travelers Rest, SC.
Aeroseal is a technology that seals duct leaks from the inside of the system in Travelers Rest. Aerosolized sealant particles are introduced into the pressurized duct system and travel to leak points where they accumulate and seal the gap in Travelers Rest, SC. It is particularly effective for sealing leaks in inaccessible duct sections that cannot be reached for manual sealant application in Travelers Rest.
Yes. Sealing duct leaks reduces the conditioned air loss the system was experiencing and delivers more of the conditioned air the HVAC produces to the living spaces in Travelers Rest. The reduction in leakage translates directly to reduced energy consumption for the same heating and cooling output in Travelers Rest, SC.
Yes for systems with return duct leakage in unconditioned spaces in Travelers Rest. Return duct leaks in attics and crawl spaces draw unconditioned air including dust, moisture, and whatever contaminants are in those spaces into the return airstream in Travelers Rest, SC. Sealing return duct leaks eliminates this pathway and keeps the circulated air to what is drawn from the living spaces in Travelers Rest.
Mastic duct sealant is expected to maintain its sealing effectiveness for the life of the duct system when correctly applied in Travelers Rest. UL 181-rated foil tape is expected to maintain adhesion for 20 years or more in normal duct system conditions in Travelers Rest, SC. Both materials significantly outlast standard duct tape in duct system applications in Travelers Rest.
Duct cleaning before sealing allows the sealant to bond to clean duct surfaces in Travelers Rest. Applying mastic to duct surfaces coated with dust and debris reduces the bond quality and long-term sealing effectiveness in Travelers Rest, SC. ISA Air Duct recommends cleaning before sealing when both services are needed and can coordinate both in a single visit in Travelers Rest.
Duct sealing costs in Travelers Rest 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 Aeroseal treatment of systems with significant inaccessible duct leakage in Travelers Rest, SC. All pricing confirmed upfront before work begins in Travelers Rest.
Yes. Every ISA Air Duct duct sealing service is guaranteed in Travelers Rest. If the sealing does not produce the expected improvement within the guarantee period, we return and address it at no additional charge in Travelers Rest, SC.
