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

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

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