Professional Duct Sealing in Olympia Fields, IL

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

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

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

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

Where Leaks Occur

Where Duct Leaks Occur and Why They Develop in Olympia Fields, IL

At Every Unsealed Duct Joint Throughout the System in Olympia Fields

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

At Branch Takeoffs From the Main Trunk Line in Olympia Fields, IL

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

At Register Boot Connections in Walls and Ceilings in Olympia Fields

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

Why Original Installation Sealant Fails Over Time in Olympia Fields, IL

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

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

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

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

Sealant Materials

What MBM Uses to Seal Duct Leaks in Olympia Fields, IL

Mastic Sealant — The Professional Standard in Olympia Fields

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

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

FAQ

Duct Sealing FAQs in Olympia Fields, IL

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