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

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