Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Humansville. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Humansville, MO. You have had the equipment checked and it is working correctly in Humansville. 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 Humansville, MO. 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 Humansville.
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 Humansville, MO. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Humansville. 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 Humansville, MO.

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 Humansville. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Humansville, MO. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Humansville. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Humansville, MO. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Humansville.
Every connection between duct sections is a potential leak point in Humansville, MO. In most residential installations, these joints were mechanically fastened without sealant during installation in Humansville. 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 Humansville, MO.
Branch takeoffs split conditioned air from the main trunk line into the individual branch runs serving each room in Humansville. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Humansville, MO. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems in Humansville.
The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Humansville, MO. 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 Humansville. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Humansville, MO.
Systems sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion from temperature cycling in Humansville. Standard duct tape on duct joints typically fails within three to five seasons of thermal cycling in Humansville, MO. Joints that were sealed with standard tape appear sealed when first applied and are open to leakage again within a few years in Humansville.
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 Humansville. The conditioned air that leaks out before reaching the register does not reach the room in Humansville, MO. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in Humansville. 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 Humansville, MO.
Return duct leaks draw air from the surrounding unconditioned space into the return airstream in Humansville. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Humansville, MO. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Humansville. This unconditioned air bypasses the filter and is distributed throughout the home in Humansville, MO.
MBM Air Duct Cleaning performs a duct pressure test before any sealing begins in Humansville, MO. A calibrated fan is connected to the duct system and pressurized to a standard test pressure in Humansville. The measured airflow represents the total leakage rate and provides the baseline for comparing with the post-sealing result in Humansville, MO.
With the system pressurized, MBM technicians work through the accessible duct system to locate every specific leak point in Humansville. Every branch takeoff. Every duct joint. Every register boot connection. Every plenum seam and air handler connection in Humansville, MO. Every identified leak point is marked for sealing in Humansville.
Mastic sealant for most duct joint and connection applications in Humansville, MO. UL 181-rated foil tape for specific sheet metal seam applications in Humansville. The correct material for the specific application in Humansville, MO.
MBM systematically seals every identified leak point in the accessible duct system in Humansville. Mastic applied at the correct thickness to cover the full joint gap and bond to the duct surfaces on both sides in Humansville, MO. Every identified leak point addressed before the post-sealing pressure test in Humansville.
After all identified leak points are sealed, MBM repeats the pressure test to measure the post-sealing leakage rate in Humansville, MO. The before and after measurements quantify the leakage reduction achieved by the sealing in Humansville. Documented evidence of the result provided to the homeowner in Humansville, MO.
Mastic is a water-based sealant specifically formulated for duct system applications in Humansville, MO. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience in Humansville. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Humansville, MO.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Humansville. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Humansville, MO. Appropriate for specific sheet metal seam applications in Humansville.
Standard silver duct tape is not rated for duct system applications in Humansville, MO. Its rubber-based adhesive dries and loses adhesion from temperature cycling in Humansville. MBM Air Duct Cleaning never uses standard duct tape for duct sealing work in Humansville, MO.
MBM performs pressure testing before and after every duct sealing service in Humansville, MO. The before and after measurements document the leakage reduction achieved in Humansville. Documented improvement, not assumed improvement in Humansville, MO.
