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

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

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