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

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