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

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

Every MBM Air Duct Cleaning duct sealing service is guaranteed in Cohoe. If the sealing does not produce the expected improvement within the guarantee period, we return and address it at no additional charge in Cohoe, AK.
All pricing confirmed upfront before work begins in Cohoe. No surprises in Cohoe, AK.
A sealing service that reduces leakage by 15 to 20 percentage points returns that proportional energy cost reduction on every subsequent energy bill in Cohoe, AK. For a home spending $200 per month on heating and cooling, a 15 percent leakage reduction saves approximately $30 per month in Cohoe. A sealing service costing $500 to $1,000 pays for itself in energy savings within 18 to 36 months in most cases in Cohoe, AK. Every month after payback is net return on the investment in Cohoe.
