Professional Duct Sealing in Mclean, TX

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

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

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

Why Correct Sealant Materials Last While Duct Tape Fails in Mclean, TX

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

Where Leaks Occur

Where Duct Leaks Occur and Why They Develop in Mclean, TX

At Every Unsealed Duct Joint Throughout the System in Mclean

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

At Branch Takeoffs From the Main Trunk Line in Mclean, TX

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

At Register Boot Connections in Walls and Ceilings in Mclean

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

Why Original Installation Sealant Fails Over Time in Mclean, TX

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

How Leaking Ducts Create Comfort Problems Room by Room in Mclean, TX

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

What Return Duct Leaks Do to Your Indoor Air Quality in Mclean, TX

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

Sealant Materials

What MBM Uses to Seal Duct Leaks in Mclean, TX

Mastic Sealant — The Professional Standard in Mclean

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

UL 181-Rated Foil Tape for Specific Applications in Mclean, TX

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

Standard Duct Tape Is Never Used in Mclean

Standard silver duct tape is not rated for duct system applications in Mclean, TX. Its rubber-based adhesive dries and loses adhesion from temperature cycling in Mclean. MBM Air Duct Cleaning never uses standard duct tape for duct sealing work in Mclean, TX.

FAQ

Duct Sealing FAQs in Mclean, TX

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