Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Boscobel. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Boscobel, WI. Maybe you have even been told your HVAC system is undersized and needs to be replaced in Boscobel. 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 Boscobel, WI. The system appears undersized because it is losing a significant portion of what it produces before that conditioned air reaches the rooms in Boscobel. A new system with the same leaky ducts loses the same percentage and produces the same disappointing results in Boscobel, WI.
Duct leakage is the loss of conditioned air through gaps, holes, and unsealed joints in the duct system in Boscobel. 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 Boscobel, WI. 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 Boscobel. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Boscobel, WI. 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 Boscobel.

We seal it correctly in Boscobel.
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 Boscobel. It is a different service from ductwork repair in Boscobel, WI. 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 Boscobel. 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 Boscobel, WI. That is the problem duct sealing addresses in Boscobel.
Duct sealing is the process of identifying and sealing every air leakage point in the duct system in Boscobel. It addresses the conditioned air loss that occurs through gaps and unsealed connections throughout the duct network in Boscobel, WI. 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 Boscobel.
Ductwork repair addresses physical structural faults including disconnected sections, torn flexible duct, and collapsed runs in Boscobel. Duct sealing addresses air leakage through the joints and connections of a structurally sound system in Boscobel, WI. A system may need repair for structural faults, sealing for joint leakage, or both in Boscobel. ISA Air Duct assesses the specific condition of the system and recommends the correct service for what is actually found in Boscobel, WI.
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 Boscobel, WI. Complete sealing of every accessible joint and connection in the system in Boscobel.
Every point where two duct sections connect is a potential leakage point in Boscobel, WI. 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 Boscobel. In most residential installations, these joints were mechanically connected without sealant in Boscobel, WI. The gaps at the joint edges allow conditioned air to escape into the surrounding space with every HVAC cycle in Boscobel.
Branch takeoffs are the fittings that split conditioned air from the main trunk line to the individual branch duct runs in Boscobel. They are connection points with multiple edges and angles that are particularly prone to leakage if not correctly sealed in Boscobel, WI. Splitter boxes in zoned systems have multiple connection points that represent significant potential leakage area in Boscobel. 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 Boscobel, WI.
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 Boscobel, WI. 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 Boscobel. Conditioned air escaping at the boot level leaks into the wall or floor cavity rather than through the register into the room in Boscobel, WI.
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 Boscobel. Without mastic sealant applied to the connection before securing, the connection leaks at the gaps between the duct liner and the fitting surface in Boscobel, WI. Mastic sealing of flexible duct collar connections is a standard component of ISA Air Duct's sealing service in Boscobel.
Systems that were initially sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion in Boscobel, WI. Standard duct tape is not rated for the temperature cycling that duct systems experience during normal operation in Boscobel. Within a few seasons, standard duct tape on duct joints fails and the underlying joint gap opens to leakage again in Boscobel, WI. 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 Boscobel.
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 Boscobel. This estimate is based on testing of real residential duct systems across a range of ages and construction types in Boscobel, WI. In systems with particularly poor initial installation or significant seal failure, the loss can be higher in Boscobel.
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 Boscobel. The conditioned air that leaks out of the supply duct before reaching the register is air that does not reach the room in Boscobel, WI. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in Boscobel. 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 Boscobel, WI.
Return duct leakage draws air from the surrounding space into the return airstream in Boscobel, WI. In an attic, that means drawing hot, dusty attic air into the air handler in summer in Boscobel. 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 Boscobel, WI. Return duct sealing eliminates this pathway and keeps the circulated air to what is drawn from the living spaces in Boscobel.
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 Boscobel. The cumulative effect is accelerated component wear across the blower motor and other system components in Boscobel, WI. Sealing the duct system reduces the load the HVAC operates under and extends the equipment service life in Boscobel.
ISA Air Duct performs duct system pressure testing before sealing to quantify the total leakage in the system in Boscobel, WI. A calibrated fan is connected to the duct system and the system is pressurized to a standard test pressure in Boscobel. The airflow required to maintain that pressure is measured in Boscobel, WI. The measured airflow represents the total leakage rate of the system and provides the baseline for comparing before and after sealing performance in Boscobel.
With the system pressurized, ISA Air Duct technicians systematically locate every specific leak point in the accessible duct system in Boscobel. A pressurized leaking duct system produces audible air movement and detectable airflow at leak points that can be located systematically in Boscobel, WI. Every identified leak point is marked for sealing in Boscobel.
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 Boscobel, WI. Mastic duct sealant for most duct joints and connections in Boscobel. UL 181-rated foil tape for specific sheet metal seam applications in Boscobel, WI. The correct material for the specific application in Boscobel.

UL 181-rated tape applied with adequate overlap and firm pressure for full adhesion in Boscobel. Every leak point addressed before the post-sealing test in Boscobel, WI.
After sealing is complete, ISA Air Duct repeats the pressure test to measure the post-sealing leakage rate in Boscobel, WI. The before and after measurements quantify the leakage reduction achieved by the sealing in Boscobel. The post-sealing test confirms the sealing produced meaningful improvement and provides documented evidence of the result in Boscobel, WI.
Mastic is a water-based sealant specifically formulated for duct system applications in Boscobel, WI. It remains flexible after curing, which means it maintains its seal through the expansion and contraction that duct systems experience during thermal cycling in Boscobel. It bonds well to sheet metal, flexible duct liners, and fibrous duct board in Boscobel, WI. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Boscobel. 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 Boscobel, WI.
UL 181-rated foil tape is a pressure-sensitive tape specifically tested and rated for HVAC duct applications in Boscobel. Unlike standard duct tape, UL 181 foil tape maintains its adhesion through the temperature cycling of duct system operation in Boscobel, WI. It is appropriate for specific sheet metal seam applications where a clean, smooth seal is needed in Boscobel. ISA Air Duct uses UL 181-rated foil tape where its specific properties make it the correct choice for the application in Boscobel, WI.
Standard silver duct tape is not rated for duct system applications in Boscobel, WI. Its rubber-based adhesive dries and loses adhesion from the temperature cycling that duct systems experience during normal operation in Boscobel. Standard duct tape on duct joints fails within a few heating and cooling seasons in Boscobel, WI. 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 Boscobel. ISA Air Duct never uses standard duct tape for duct sealing work in Boscobel, WI.
Aeroseal is a duct sealing technology that seals leaks from the inside of the duct system in Boscobel. 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 Boscobel, WI. Aeroseal is particularly effective for sealing leaks in inaccessible duct sections that cannot be reached for manual sealant application in Boscobel. ISA Air Duct provides information on Aeroseal duct sealing for systems where inaccessible duct sections represent significant leakage that manual sealing cannot address in Boscobel, WI.
