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

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