Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Marathon. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Marathon, FL. You have had the equipment checked and it is working correctly in Marathon. 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 Marathon, 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 Marathon.
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 Marathon, FL. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Marathon. 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 Marathon, 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 Marathon. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Marathon, FL. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Marathon. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Marathon, FL. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Marathon.
Every connection between duct sections is a potential leak point in Marathon, FL. In most residential installations, these joints were mechanically fastened without sealant during installation in Marathon. 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 Marathon, FL.
Branch takeoffs split conditioned air from the main trunk line into the individual branch runs serving each room in Marathon. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Marathon, FL. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems in Marathon.
The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Marathon, 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 Marathon. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Marathon, FL.
Systems sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion from temperature cycling in Marathon. Standard duct tape on duct joints typically fails within three to five seasons of thermal cycling in Marathon, FL. Joints that were sealed with standard tape appear sealed when first applied and are open to leakage again within a few years in Marathon.
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 Marathon. The conditioned air that leaks out before reaching the register does not reach the room in Marathon, 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 Marathon. 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 Marathon, FL.
Return duct leaks draw air from the surrounding unconditioned space into the return airstream in Marathon. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Marathon, FL. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Marathon. This unconditioned air bypasses the filter and is distributed throughout the home in Marathon, FL.
MBM Air Duct Cleaning performs a duct pressure test before any sealing begins in Marathon, FL. A calibrated fan is connected to the duct system and pressurized to a standard test pressure in Marathon. The measured airflow represents the total leakage rate and provides the baseline for comparing with the post-sealing result in Marathon, FL.
With the system pressurized, MBM technicians work through the accessible duct system to locate every specific leak point in Marathon. Every branch takeoff. Every duct joint. Every register boot connection. Every plenum seam and air handler connection in Marathon, FL. Every identified leak point is marked for sealing in Marathon.
Mastic sealant for most duct joint and connection applications in Marathon, FL. UL 181-rated foil tape for specific sheet metal seam applications in Marathon. The correct material for the specific application in Marathon, FL.
MBM systematically seals every identified leak point in the accessible duct system in Marathon. Mastic applied at the correct thickness to cover the full joint gap and bond to the duct surfaces on both sides in Marathon, FL. Every identified leak point addressed before the post-sealing pressure test in Marathon.
After all identified leak points are sealed, MBM repeats the pressure test to measure the post-sealing leakage rate in Marathon, FL. The before and after measurements quantify the leakage reduction achieved by the sealing in Marathon. Documented evidence of the result provided to the homeowner in Marathon, FL.
Mastic is a water-based sealant specifically formulated for duct system applications in Marathon, FL. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience in Marathon. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Marathon, FL.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Marathon. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Marathon, FL. Appropriate for specific sheet metal seam applications in Marathon.
Standard silver duct tape is not rated for duct system applications in Marathon, FL. Its rubber-based adhesive dries and loses adhesion from temperature cycling in Marathon. MBM Air Duct Cleaning never uses standard duct tape for duct sealing work in Marathon, FL.
MBM performs pressure testing before and after every duct sealing service in Marathon, FL. The before and after measurements document the leakage reduction achieved in Marathon. Documented improvement, not assumed improvement in Marathon, FL.
MBM seals every identified leak point in the accessible duct system in Marathon. Not a representative sample. Not the most obvious points only in Marathon, FL. Every identified leak point in Marathon.
Mastic sealant and UL 181-rated foil tape that maintain their effectiveness through the thermal cycling of long-term HVAC operation in Marathon, FL. Never standard duct tape in Marathon.
Every MBM Air Duct Cleaning duct sealing service is guaranteed in Marathon. If the sealing does not produce the expected improvement within the guarantee period, we return and address it at no additional charge in Marathon, FL.
All pricing confirmed upfront before work begins in Marathon. No surprises in Marathon, FL.
A sealing service that reduces leakage by 15 to 20 percentage points returns that proportional energy cost reduction on every subsequent energy bill in Marathon, FL. For a home spending $200 per month on heating and cooling, a 15 percent leakage reduction saves approximately $30 per month in Marathon. A sealing service costing $500 to $1,000 pays for itself in energy savings within 18 to 36 months in most cases in Marathon, FL. Every month after payback is net return on the investment in Marathon.
