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

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

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