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

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

Every MBM Air Duct Cleaning duct sealing service is guaranteed in Winthrop Harbor. If the sealing does not produce the expected improvement within the guarantee period, we return and address it at no additional charge in Winthrop Harbor, IL.
All pricing confirmed upfront before work begins in Winthrop Harbor. No surprises in Winthrop Harbor, IL.
A sealing service that reduces leakage by 15 to 20 percentage points returns that proportional energy cost reduction on every subsequent energy bill in Winthrop Harbor, IL. For a home spending $200 per month on heating and cooling, a 15 percent leakage reduction saves approximately $30 per month in Winthrop Harbor. A sealing service costing $500 to $1,000 pays for itself in energy savings within 18 to 36 months in most cases in Winthrop Harbor, IL. Every month after payback is net return on the investment in Winthrop Harbor.
