Professional Duct Sealing in Nelsonville, OH

Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Nelsonville. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Nelsonville, OH. You have had the equipment checked and it is working correctly in Nelsonville. 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 Nelsonville, OH. 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 Nelsonville.

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 Nelsonville, OH. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Nelsonville. 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 Nelsonville, OH.

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

Why Correct Sealant Materials Last While Duct Tape Fails in Nelsonville, OH

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 Nelsonville. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Nelsonville, OH. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Nelsonville. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Nelsonville, OH. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Nelsonville.

Where Leaks Occur

Where Duct Leaks Occur and Why They Develop in Nelsonville, OH

At Every Unsealed Duct Joint Throughout the System in Nelsonville

Every connection between duct sections is a potential leak point in Nelsonville, OH. In most residential installations, these joints were mechanically fastened without sealant during installation in Nelsonville. 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 Nelsonville, OH.

At Branch Takeoffs From the Main Trunk Line in Nelsonville, OH

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

At Register Boot Connections in Walls and Ceilings in Nelsonville

The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Nelsonville, OH. 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 Nelsonville. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Nelsonville, OH.

Why Original Installation Sealant Fails Over Time in Nelsonville, OH

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

How Leaking Ducts Create Comfort Problems Room by Room in Nelsonville, OH

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 Nelsonville. The conditioned air that leaks out before reaching the register does not reach the room in Nelsonville, OH. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in Nelsonville. 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 Nelsonville, OH.

What Return Duct Leaks Do to Your Indoor Air Quality in Nelsonville, OH

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

Sealant Materials

What MBM Uses to Seal Duct Leaks in Nelsonville, OH

Mastic Sealant — The Professional Standard in Nelsonville

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

UL 181-Rated Foil Tape for Specific Applications in Nelsonville, OH

UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Nelsonville. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Nelsonville, OH. Appropriate for specific sheet metal seam applications in Nelsonville.

Standard Duct Tape Is Never Used in Nelsonville

FAQ

Duct Sealing FAQs in Nelsonville, OH

The clearest indicators in Nelsonville 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 Nelsonville, OH. Pressure testing is the definitive way to quantify the leakage in your specific system in Nelsonville.
A duct pressure test connects a calibrated fan to the duct system and pressurizes it to a standard test pressure in Nelsonville. The airflow required to maintain that pressure is measured in Nelsonville, OH. The measured airflow represents the total leakage rate of the system in Nelsonville. MBM Air Duct Cleaning performs pressure testing before and after every duct sealing service in Nelsonville, OH.
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 Nelsonville. In systems with particularly poor sealing or failed original sealant, the loss can exceed 30 percent in Nelsonville, OH.
Duct cleaning before duct sealing allows the mastic sealant to bond to clean duct surfaces in Nelsonville. Applying mastic to duct surfaces coated with accumulated dust and debris reduces the bond quality and long-term sealing effectiveness in Nelsonville, OH. MBM Air Duct Cleaning recommends cleaning before sealing when both services are needed and can coordinate both in a single visit in Nelsonville.
Mastic is a water-based sealant specifically formulated for duct system applications in Nelsonville. It remains flexible after curing and maintains its seal through the thermal cycling that duct systems experience during operation in Nelsonville, OH. Standard duct tape uses a rubber-based adhesive that dries and loses adhesion from temperature cycling, failing within a few seasons in Nelsonville.
Yes. Return duct leaks in crawl spaces draw crawl space air including its elevated moisture content into the return airstream in Nelsonville. The additional moisture enters the air handler and is distributed throughout the home in Nelsonville, OH. Indoor relative humidity rises despite the air conditioner running because the additional crawl space moisture load overwhelms the system's dehumidification capacity in Nelsonville.
Aeroseal is a technology that seals duct leaks from inside the pressurized duct system in Nelsonville. Aerosolized sealant particles are introduced into the system and travel to leak points where they accumulate and seal the gap in Nelsonville, OH. 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 Nelsonville.
Mastic duct sealant maintains its sealing effectiveness for the life of the duct system when correctly applied in Nelsonville. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Nelsonville, OH. Both materials significantly outlast standard duct tape in duct system applications in Nelsonville.
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 Nelsonville. The reduction in leakage translates directly to reduced energy consumption for the same heating and cooling output in Nelsonville, OH.
Yes for systems with return duct leaks in unconditioned spaces in Nelsonville. Return duct leaks in attics and crawl spaces draw unconditioned air including dust, moisture, and mold spores into the return airstream in Nelsonville, OH. Sealing these leaks eliminates the pathway and keeps the circulated air to what is drawn from the living spaces in Nelsonville.
Duct sealing costs in Nelsonville 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 Nelsonville, OH. All pricing confirmed upfront before work begins in Nelsonville.
Yes. Every MBM Air Duct Cleaning duct sealing service is guaranteed in Nelsonville. If the sealing does not produce the expected improvement within the guarantee period, we return and address it at no additional charge in Nelsonville, OH.
