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 Storrs. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Storrs, CT. Maybe you have even been told your HVAC system is undersized and needs to be replaced in Storrs. 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 Storrs, CT. The system appears undersized because it is losing a significant portion of what it produces before that conditioned air reaches the rooms in Storrs. A new system with the same leaky ducts loses the same percentage and produces the same disappointing results in Storrs, CT.

Duct leakage is the loss of conditioned air through gaps, holes, and unsealed joints in the duct system in Storrs. 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 Storrs, CT. 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 Storrs. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Storrs, CT. 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 Storrs.

Professional Duct Sealing in Storrs, CT

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 Storrs. It is a different service from ductwork repair in Storrs, CT. 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 Storrs. 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 Storrs, CT. That is the problem duct sealing addresses in Storrs.

What Duct Sealing Is and What It Addresses in Storrs, CT

Duct sealing is the process of identifying and sealing every air leakage point in the duct system in Storrs. It addresses the conditioned air loss that occurs through gaps and unsealed connections throughout the duct network in Storrs, CT. 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 Storrs.

Why Duct Sealing Is Distinct From Ductwork Repair in Storrs, CT

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

What ISA Air Duct's Sealing Service Covers in Storrs

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 Storrs, CT. Complete sealing of every accessible joint and connection in the system in Storrs.

Where Leakage Occurs

Where Duct Leakage Occurs and Why It Develops in Storrs, CT

At Duct Joints and Connections in Storrs

Every point where two duct sections connect is a potential leakage point in Storrs, CT. 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 Storrs. In most residential installations, these joints were mechanically connected without sealant in Storrs, CT. The gaps at the joint edges allow conditioned air to escape into the surrounding space with every HVAC cycle in Storrs.

At Branch Takeoffs and Splitter Boxes in Storrs, CT

Branch takeoffs are the fittings that split conditioned air from the main trunk line to the individual branch duct runs in Storrs. They are connection points with multiple edges and angles that are particularly prone to leakage if not correctly sealed in Storrs, CT. Splitter boxes in zoned systems have multiple connection points that represent significant potential leakage area in Storrs. 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 Storrs, CT.

At Register Boot Connections in Storrs

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 Storrs, CT. 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 Storrs. Conditioned air escaping at the boot level leaks into the wall or floor cavity rather than through the register into the room in Storrs, CT.

In Flexible Duct Collar Connections in Storrs, CT

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 Storrs. Without mastic sealant applied to the connection before securing, the connection leaks at the gaps between the duct liner and the fitting surface in Storrs, CT. Mastic sealing of flexible duct collar connections is a standard component of ISA Air Duct's sealing service in Storrs.

Why Leakage Develops in Systems That Were Initially Sealed in Storrs

Systems that were initially sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion in Storrs, CT. Standard duct tape is not rated for the temperature cycling that duct systems experience during normal operation in Storrs. Within a few seasons, standard duct tape on duct joints fails and the underlying joint gap opens to leakage again in Storrs, CT. 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 Storrs.

What Leakage Costs You

What Duct Leakage Costs You Every Month in Storrs, CT

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 Storrs, CT

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 Storrs. This estimate is based on testing of real residential duct systems across a range of ages and construction types in Storrs, CT. In systems with particularly poor initial installation or significant seal failure, the loss can be higher in Storrs.

How Leakage Causes Uneven Heating and Cooling in Storrs, CT

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 Storrs. The conditioned air that leaks out of the supply duct before reaching the register is air that does not reach the room in Storrs, CT. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in Storrs. 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 Storrs, CT.

What Return Duct Leakage Does to Indoor Air Quality in Storrs

Return duct leakage draws air from the surrounding space into the return airstream in Storrs, CT. In an attic, that means drawing hot, dusty attic air into the air handler in summer in Storrs. 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 Storrs, CT. Return duct sealing eliminates this pathway and keeps the circulated air to what is drawn from the living spaces in Storrs.

The Hidden Equipment Cost of Running a Leaky Duct System in Storrs, CT

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 Storrs. The cumulative effect is accelerated component wear across the blower motor and other system components in Storrs, CT. Sealing the duct system reduces the load the HVAC operates under and extends the equipment service life in Storrs.

How We Seal Your System

How ISA Air Duct Finds and Seals Every Leak Point in Storrs, CT

1

Duct System Pressure Testing — Quantifying the Leakage in Storrs

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

2

Leak Location — Finding Every Specific Leak Point in Storrs, CT

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

3

Correct Sealant for the Specific Joint Type in Storrs

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 Storrs, CT. Mastic duct sealant for most duct joints and connections in Storrs. UL 181-rated foil tape for specific sheet metal seam applications in Storrs, CT. The correct material for the specific application in Storrs.

4

Systematic Sealing of Every Identified Leak Point in Storrs, CT

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

5

Post-Sealing Pressure Test — Confirming the Improvement in Storrs

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

Sealant Materials

What ISA Air Duct Uses to Seal Duct Leaks in Storrs, CT

Mastic Duct Sealant — The Correct Choice for Most Applications in Storrs

Mastic is a water-based sealant specifically formulated for duct system applications in Storrs, CT. It remains flexible after curing, which means it maintains its seal through the expansion and contraction that duct systems experience during thermal cycling in Storrs. It bonds well to sheet metal, flexible duct liners, and fibrous duct board in Storrs, CT. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Storrs. 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 Storrs, CT.

UL 181-Rated Foil Tape — For Specific Seam Applications in Storrs, CT

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

Why Standard Duct Tape Is Never Used in Storrs

Standard silver duct tape is not rated for duct system applications in Storrs, CT. Its rubber-based adhesive dries and loses adhesion from the temperature cycling that duct systems experience during normal operation in Storrs. Standard duct tape on duct joints fails within a few heating and cooling seasons in Storrs, CT. 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 Storrs. ISA Air Duct never uses standard duct tape for duct sealing work in Storrs, CT.

Aeroseal Duct Sealing for Inaccessible Ducts in Storrs, CT

Aeroseal is a duct sealing technology that seals leaks from the inside of the duct system in Storrs. 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 Storrs, CT. Aeroseal is particularly effective for sealing leaks in inaccessible duct sections that cannot be reached for manual sealant application in Storrs. ISA Air Duct provides information on Aeroseal duct sealing for systems where inaccessible duct sections represent significant leakage that manual sealing cannot address in Storrs, CT.

FAQ

Duct Sealing FAQs in Storrs, CT

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 Storrs. 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 Storrs, CT. 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 Storrs.
The clearest indicators in Storrs 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 Storrs, CT. Pressure testing by a professional is the definitive way to quantify the leakage in your specific system in Storrs.
A duct leakage test connects a calibrated fan to the duct system and pressurizes it to a standard test pressure in Storrs. The airflow required to maintain that pressure is measured in Storrs, CT. The measured airflow represents the total leakage rate of the system and is typically expressed as a percentage of the total system airflow in Storrs. ISA Air Duct performs pressure testing before and after every duct sealing service in Storrs, CT.
Ductwork repair addresses physical structural damage including disconnected sections, torn flexible duct, and collapsed runs in Storrs. Duct sealing addresses air leakage through the joints and connections of a structurally sound system in Storrs, CT. A system may need both repair and sealing, or one without the other, depending on its specific condition in Storrs.
Mastic is a water-based sealant specifically formulated for duct system applications in Storrs. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience during operation in Storrs, CT. Standard duct tape uses a rubber-based adhesive that dries and loses adhesion from temperature cycling, failing within a few seasons in Storrs. Mastic does not dry out, crack, or lose adhesion from temperature cycling in Storrs, CT.
Aeroseal is a technology that seals duct leaks from the inside of the system in Storrs. Aerosolized sealant particles are introduced into the pressurized duct system and travel to leak points where they accumulate and seal the gap in Storrs, CT. It is particularly effective for sealing leaks in inaccessible duct sections that cannot be reached for manual sealant application in Storrs.
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 Storrs. The reduction in leakage translates directly to reduced energy consumption for the same heating and cooling output in Storrs, CT.
Yes for systems with return duct leakage in unconditioned spaces in Storrs. 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 Storrs, CT. Sealing return duct leaks eliminates this pathway and keeps the circulated air to what is drawn from the living spaces in Storrs.
Mastic duct sealant is expected to maintain its sealing effectiveness for the life of the duct system when correctly applied in Storrs. UL 181-rated foil tape is expected to maintain adhesion for 20 years or more in normal duct system conditions in Storrs, CT. Both materials significantly outlast standard duct tape in duct system applications in Storrs.
Duct cleaning before sealing allows the sealant to bond to clean duct surfaces in Storrs. Applying mastic to duct surfaces coated with dust and debris reduces the bond quality and long-term sealing effectiveness in Storrs, CT. ISA Air Duct recommends cleaning before sealing when both services are needed and can coordinate both in a single visit in Storrs.
Duct sealing costs in Storrs 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 Storrs, CT. All pricing confirmed upfront before work begins in Storrs.
Yes. Every ISA Air Duct duct sealing service is guaranteed in Storrs. If the sealing does not produce the expected improvement within the guarantee period, we return and address it at no additional charge in Storrs, CT.
