Professional Duct Sealing in Midlothian, TX

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

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

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

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

Where Leaks Occur

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

At Every Unsealed Duct Joint Throughout the System in Midlothian

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

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

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

At Register Boot Connections in Walls and Ceilings in Midlothian

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

Why Original Installation Sealant Fails Over Time in Midlothian, TX

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

How Leaking Ducts Create Comfort Problems Room by Room in Midlothian, 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 Midlothian. The conditioned air that leaks out before reaching the register does not reach the room in Midlothian, 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 Midlothian. 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 Midlothian, TX.

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

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

Sealant Materials

What MBM Uses to Seal Duct Leaks in Midlothian, TX

Mastic Sealant — The Professional Standard in Midlothian

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

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

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

Standard Duct Tape Is Never Used in Midlothian

FAQ

Duct Sealing FAQs in Midlothian, TX

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