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

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

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