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

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