Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Emsworth. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Emsworth, PA. You have had the equipment checked and it is working correctly in Emsworth. 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 Emsworth, 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 Emsworth.
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 Emsworth, PA. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Emsworth. 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 Emsworth, 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 Emsworth. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Emsworth, PA. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Emsworth. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Emsworth, PA. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Emsworth.
Every connection between duct sections is a potential leak point in Emsworth, PA. In most residential installations, these joints were mechanically fastened without sealant during installation in Emsworth. 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 Emsworth, PA.
Branch takeoffs split conditioned air from the main trunk line into the individual branch runs serving each room in Emsworth. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Emsworth, PA. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems in Emsworth.
The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Emsworth, 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 Emsworth. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Emsworth, PA.
Systems sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion from temperature cycling in Emsworth. Standard duct tape on duct joints typically fails within three to five seasons of thermal cycling in Emsworth, PA. Joints that were sealed with standard tape appear sealed when first applied and are open to leakage again within a few years in Emsworth.
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 Emsworth. The conditioned air that leaks out before reaching the register does not reach the room in Emsworth, 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 Emsworth. 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 Emsworth, PA.
Return duct leaks draw air from the surrounding unconditioned space into the return airstream in Emsworth. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Emsworth, PA. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Emsworth. This unconditioned air bypasses the filter and is distributed throughout the home in Emsworth, PA.
MBM Air Duct Cleaning performs a duct pressure test before any sealing begins in Emsworth, PA. A calibrated fan is connected to the duct system and pressurized to a standard test pressure in Emsworth. The measured airflow represents the total leakage rate and provides the baseline for comparing with the post-sealing result in Emsworth, PA.
With the system pressurized, MBM technicians work through the accessible duct system to locate every specific leak point in Emsworth. Every branch takeoff. Every duct joint. Every register boot connection. Every plenum seam and air handler connection in Emsworth, PA. Every identified leak point is marked for sealing in Emsworth.

After all identified leak points are sealed, MBM repeats the pressure test to measure the post-sealing leakage rate in Emsworth, PA. The before and after measurements quantify the leakage reduction achieved by the sealing in Emsworth. Documented evidence of the result provided to the homeowner in Emsworth, PA.
Mastic is a water-based sealant specifically formulated for duct system applications in Emsworth, PA. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience in Emsworth. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Emsworth, PA.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Emsworth. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Emsworth, PA. Appropriate for specific sheet metal seam applications in Emsworth.
