Professional Duct Sealing in Security-Widefield, CO

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

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 Security-Widefield, CO. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Security-Widefield. 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 Security-Widefield, CO.

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

Why Correct Sealant Materials Last While Duct Tape Fails in Security-Widefield, CO

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

Where Leaks Occur

Where Duct Leaks Occur and Why They Develop in Security-Widefield, CO

At Every Unsealed Duct Joint Throughout the System in Security-Widefield

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

At Branch Takeoffs From the Main Trunk Line in Security-Widefield, CO

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

At Register Boot Connections in Walls and Ceilings in Security-Widefield

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

Why Original Installation Sealant Fails Over Time in Security-Widefield, CO

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

How Leaking Ducts Create Comfort Problems Room by Room in Security-Widefield, CO

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

What Return Duct Leaks Do to Your Indoor Air Quality in Security-Widefield, CO

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

Sealant Materials

What MBM Uses to Seal Duct Leaks in Security-Widefield, CO

Mastic Sealant — The Professional Standard in Security-Widefield

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

UL 181-Rated Foil Tape for Specific Applications in Security-Widefield, CO

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

Standard Duct Tape Is Never Used in Security-Widefield

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

FAQ

Duct Sealing FAQs in Security-Widefield, CO

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