Professional Duct Sealing in Vail, CO

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

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

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

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

Where Leaks Occur

Where Duct Leaks Occur and Why They Develop in Vail, CO

At Every Unsealed Duct Joint Throughout the System in Vail

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

At Branch Takeoffs From the Main Trunk Line in Vail, CO

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

At Register Boot Connections in Walls and Ceilings in Vail

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

Why Original Installation Sealant Fails Over Time in Vail, CO

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

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

What Return Duct Leaks Do to Your Indoor Air Quality in Vail, CO

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

Sealant Materials

What MBM Uses to Seal Duct Leaks in Vail, CO

Mastic Sealant — The Professional Standard in Vail

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

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

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

Standard Duct Tape Is Never Used in Vail

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

FAQ

Duct Sealing FAQs in Vail, CO

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