Professional Duct Sealing in Millstadt, IL

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

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

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

Why Correct Sealant Materials Last While Duct Tape Fails in Millstadt, IL

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

Where Leaks Occur

Where Duct Leaks Occur and Why They Develop in Millstadt, IL

At Every Unsealed Duct Joint Throughout the System in Millstadt

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

At Branch Takeoffs From the Main Trunk Line in Millstadt, IL

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

At Register Boot Connections in Walls and Ceilings in Millstadt

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

Why Original Installation Sealant Fails Over Time in Millstadt, IL

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

How Leaking Ducts Create Comfort Problems Room by Room in Millstadt, IL

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

What Return Duct Leaks Do to Your Indoor Air Quality in Millstadt, IL

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

Sealant Materials

What MBM Uses to Seal Duct Leaks in Millstadt, IL

Mastic Sealant — The Professional Standard in Millstadt

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

UL 181-Rated Foil Tape for Specific Applications in Millstadt, IL

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

Standard Duct Tape Is Never Used in Millstadt

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

FAQ

Duct Sealing FAQs in Millstadt, IL

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