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

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

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