Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Fairland. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Fairland, MD. You have had the equipment checked and it is working correctly in Fairland. 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 Fairland, 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 Fairland.
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 Fairland, MD. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Fairland. 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 Fairland, 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 Fairland. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Fairland, MD. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Fairland. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Fairland, MD. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Fairland.
Every connection between duct sections is a potential leak point in Fairland, MD. In most residential installations, these joints were mechanically fastened without sealant during installation in Fairland. 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 Fairland, MD.
Branch takeoffs split conditioned air from the main trunk line into the individual branch runs serving each room in Fairland. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Fairland, MD. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems in Fairland.
The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Fairland, 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 Fairland. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Fairland, MD.
Systems sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion from temperature cycling in Fairland. Standard duct tape on duct joints typically fails within three to five seasons of thermal cycling in Fairland, MD. Joints that were sealed with standard tape appear sealed when first applied and are open to leakage again within a few years in Fairland.
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 Fairland. The conditioned air that leaks out before reaching the register does not reach the room in Fairland, 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 Fairland. 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 Fairland, MD.
Return duct leaks draw air from the surrounding unconditioned space into the return airstream in Fairland. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Fairland, MD. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Fairland. This unconditioned air bypasses the filter and is distributed throughout the home in Fairland, MD.
MBM Air Duct Cleaning performs a duct pressure test before any sealing begins in Fairland, MD. A calibrated fan is connected to the duct system and pressurized to a standard test pressure in Fairland. The measured airflow represents the total leakage rate and provides the baseline for comparing with the post-sealing result in Fairland, MD.
With the system pressurized, MBM technicians work through the accessible duct system to locate every specific leak point in Fairland. Every branch takeoff. Every duct joint. Every register boot connection. Every plenum seam and air handler connection in Fairland, MD. Every identified leak point is marked for sealing in Fairland.
Mastic sealant for most duct joint and connection applications in Fairland, MD. UL 181-rated foil tape for specific sheet metal seam applications in Fairland. The correct material for the specific application in Fairland, MD.
MBM systematically seals every identified leak point in the accessible duct system in Fairland. Mastic applied at the correct thickness to cover the full joint gap and bond to the duct surfaces on both sides in Fairland, MD. Every identified leak point addressed before the post-sealing pressure test in Fairland.
After all identified leak points are sealed, MBM repeats the pressure test to measure the post-sealing leakage rate in Fairland, MD. The before and after measurements quantify the leakage reduction achieved by the sealing in Fairland. Documented evidence of the result provided to the homeowner in Fairland, MD.
Mastic is a water-based sealant specifically formulated for duct system applications in Fairland, MD. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience in Fairland. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Fairland, MD.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Fairland. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Fairland, MD. Appropriate for specific sheet metal seam applications in Fairland.
Standard silver duct tape is not rated for duct system applications in Fairland, MD. Its rubber-based adhesive dries and loses adhesion from temperature cycling in Fairland. MBM Air Duct Cleaning never uses standard duct tape for duct sealing work in Fairland, MD.
MBM performs pressure testing before and after every duct sealing service in Fairland, MD. The before and after measurements document the leakage reduction achieved in Fairland. Documented improvement, not assumed improvement in Fairland, MD.
MBM seals every identified leak point in the accessible duct system in Fairland. Not a representative sample. Not the most obvious points only in Fairland, MD. Every identified leak point in Fairland.

A sealing service that reduces leakage by 15 to 20 percentage points returns that proportional energy cost reduction on every subsequent energy bill in Fairland, MD. For a home spending $200 per month on heating and cooling, a 15 percent leakage reduction saves approximately $30 per month in Fairland. A sealing service costing $500 to $1,000 pays for itself in energy savings within 18 to 36 months in most cases in Fairland, MD. Every month after payback is net return on the investment in Fairland.
