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