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

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