Professional Duct Sealing in Islamorada Village Of Islands, FL

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

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 Islamorada Village Of Islands, FL. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Islamorada Village Of Islands. 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 Islamorada Village Of Islands, FL.

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

Why Correct Sealant Materials Last While Duct Tape Fails in Islamorada Village Of Islands, FL

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

Where Leaks Occur

Where Duct Leaks Occur and Why They Develop in Islamorada Village Of Islands, FL

At Every Unsealed Duct Joint Throughout the System in Islamorada Village Of Islands

Every connection between duct sections is a potential leak point in Islamorada Village Of Islands, FL. In most residential installations, these joints were mechanically fastened without sealant during installation in Islamorada Village Of Islands. 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 Islamorada Village Of Islands, FL.

At Branch Takeoffs From the Main Trunk Line in Islamorada Village Of Islands, FL

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

At Register Boot Connections in Walls and Ceilings in Islamorada Village Of Islands

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

Why Original Installation Sealant Fails Over Time in Islamorada Village Of Islands, FL

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

How Leaking Ducts Create Comfort Problems Room by Room in Islamorada Village Of Islands, FL

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

What Return Duct Leaks Do to Your Indoor Air Quality in Islamorada Village Of Islands, FL

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

FAQ

Duct Sealing FAQs in Islamorada Village Of Islands, FL

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