Professional Duct Sealing in Union Springs, NY

Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Union Springs. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Union Springs, NY. You have had the equipment checked and it is working correctly in Union Springs. If the equipment is fine but the home is not comfortable and the bills are high, the problem is almost certainly in the distribution system in Union Springs, NY. Specifically, in duct leaks that are allowing conditioned air to escape into unconditioned attic or crawl space before it reaches the rooms you are paying to heat and cool in Union Springs.

Duct leakage happens at every unsealed joint between duct sections, at every branch takeoff from the trunk line, at every register boot connection in the walls and ceilings, and at the connections where the duct system meets the air handler in Union Springs, NY. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Union Springs. For a home spending $200 per month on heating and cooling, that is $40 to $60 per month escaping through duct leaks to the attic or crawl space in Union Springs, NY.

MBM Air Duct Cleaning finds and seals duct leaks throughout Union Springs, NY in Union Springs. Pressure testing before sealing to quantify the total leakage in Union Springs, NY. Systematic identification of every specific leak point through the accessible system in Union Springs. Correct sealant materials applied to every leak point in Union Springs, NY. Post-sealing pressure testing to document the improvement with measured numbers in Union Springs. And a guarantee on every sealing service in Union Springs, NY. Call now for same-day scheduling in Union Springs.

Why Correct Sealant Materials Last While Duct Tape Fails in Union Springs, NY

Standard duct tape uses a rubber-based adhesive that performs at room temperature but dries and loses adhesion when repeatedly exposed to the temperature extremes that duct systems experience during HVAC operation in Union Springs. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Union Springs, NY. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Union Springs. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Union Springs, NY. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Union Springs.

Where Leaks Occur

Where Duct Leaks Occur and Why They Develop in Union Springs, NY

At Every Unsealed Duct Joint Throughout the System in Union Springs

Every connection between duct sections is a potential leak point in Union Springs, NY. In most residential installations, these joints were mechanically fastened without sealant during installation in Union Springs. Over years of thermal cycling that expands and contracts the ductwork with every HVAC cycle, even joints that were initially sealed with standard duct tape have failed as the tape dried and lost adhesion in Union Springs, NY.

At Branch Takeoffs From the Main Trunk Line in Union Springs, NY

Branch takeoffs split conditioned air from the main trunk line into the individual branch runs serving each room in Union Springs. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Union Springs, NY. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems in Union Springs.

At Register Boot Connections in Walls and Ceilings in Union Springs

The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Union Springs, NY. The connection between the flexible duct and the boot collar and the connection between the boot and the surrounding framing are both common significant leak points in Union Springs. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Union Springs, NY.

Why Original Installation Sealant Fails Over Time in Union Springs, NY

Systems sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion from temperature cycling in Union Springs. Standard duct tape on duct joints typically fails within three to five seasons of thermal cycling in Union Springs, NY. Joints that were sealed with standard tape appear sealed when first applied and are open to leakage again within a few years in Union Springs.

How Leaking Ducts Create Comfort Problems Room by Room in Union Springs, NY

Supply duct leakage between the trunk line and the registers means rooms furthest from the air handler receive less conditioned air than they were designed to receive in Union Springs. The conditioned air that leaks out before reaching the register does not reach the room in Union Springs, 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 Union Springs. The room that is always too hot in summer and too cold in winter is often at the end of a duct run with multiple unsealed joints in Union Springs, NY.

What Return Duct Leaks Do to Your Indoor Air Quality in Union Springs, NY

Return duct leaks draw air from the surrounding unconditioned space into the return airstream in Union Springs. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Union Springs, NY. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Union Springs. This unconditioned air bypasses the filter and is distributed throughout the home in Union Springs, NY.

Sealant Materials

What MBM Uses to Seal Duct Leaks in Union Springs, NY

Mastic Sealant — The Professional Standard in Union Springs

Mastic is a water-based sealant specifically formulated for duct system applications in Union Springs, NY. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience in Union Springs. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Union Springs, NY.

UL 181-Rated Foil Tape for Specific Applications in Union Springs, NY

UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Union Springs. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Union Springs, NY.

FAQ

Duct Sealing FAQs in Union Springs, NY

The clearest indicators in Union Springs are energy bills that seem high relative to your usage, rooms that consistently will not reach the right temperature, an HVAC system that runs continuously without achieving comfort setpoint, higher than expected dust levels throughout the home, and humidity problems during cooling season in Union Springs, NY. Pressure testing is the definitive way to quantify the leakage in your specific system in Union Springs.
A duct pressure test connects a calibrated fan to the duct system and pressurizes it to a standard test pressure in Union Springs. The airflow required to maintain that pressure is measured in Union Springs, NY. The measured airflow represents the total leakage rate of the system in Union Springs. MBM Air Duct Cleaning performs pressure testing before and after every duct sealing service in Union Springs, NY.
The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage before it reaches the living spaces in Union Springs. In systems with particularly poor sealing or failed original sealant, the loss can exceed 30 percent in Union Springs, NY.
Duct cleaning before duct sealing allows the mastic sealant to bond to clean duct surfaces in Union Springs. Applying mastic to duct surfaces coated with accumulated dust and debris reduces the bond quality and long-term sealing effectiveness in Union Springs, NY. MBM Air Duct Cleaning recommends cleaning before sealing when both services are needed and can coordinate both in a single visit in Union Springs.
Mastic is a water-based sealant specifically formulated for duct system applications in Union Springs. It remains flexible after curing and maintains its seal through the thermal cycling that duct systems experience during operation in Union Springs, NY. Standard duct tape uses a rubber-based adhesive that dries and loses adhesion from temperature cycling, failing within a few seasons in Union Springs.
Yes. Return duct leaks in crawl spaces draw crawl space air including its elevated moisture content into the return airstream in Union Springs. The additional moisture enters the air handler and is distributed throughout the home in Union Springs, NY. Indoor relative humidity rises despite the air conditioner running because the additional crawl space moisture load overwhelms the system's dehumidification capacity in Union Springs.
Aeroseal is a technology that seals duct leaks from inside the pressurized duct system in Union Springs. Aerosolized sealant particles are introduced into the system and travel to leak points where they accumulate and seal the gap in Union Springs, NY. It is needed when significant leakage exists in duct sections in wall cavities or ceiling plenums that cannot be physically accessed for manual sealant application in Union Springs.
Mastic duct sealant maintains its sealing effectiveness for the life of the duct system when correctly applied in Union Springs. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Union Springs, NY. Both materials significantly outlast standard duct tape in duct system applications in Union Springs.
Yes. Sealing the duct system reduces the conditioned air loss the system was experiencing and delivers more of the conditioned air the HVAC produces to the living spaces in Union Springs. The reduction in leakage translates directly to reduced energy consumption for the same heating and cooling output in Union Springs, NY.
Yes for systems with return duct leaks in unconditioned spaces in Union Springs. Return duct leaks in attics and crawl spaces draw unconditioned air including dust, moisture, and mold spores into the return airstream in Union Springs, NY. Sealing these leaks eliminates the pathway and keeps the circulated air to what is drawn from the living spaces in Union Springs.
Duct sealing costs in Union Springs range from $300 to $600 for smaller systems, $500 to $1,000 for standard residential systems, $800 to $1,500 and above for larger systems, and $1,500 to $3,000 and above for systems requiring Aeroseal treatment in Union Springs, NY. All pricing confirmed upfront before work begins in Union Springs.
Yes. Every MBM Air Duct Cleaning duct sealing service is guaranteed in Union Springs. If the sealing does not produce the expected improvement within the guarantee period, we return and address it at no additional charge in Union Springs, NY.
