Pressure testing before sealing quantifies total leakage. Every leak point located and sealed with correct materials. Post-sealing pressure test documents the improvement. Every service guaranteed.
Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Sunriver. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Sunriver, OR. You have had the equipment checked and it is working correctly in Sunriver. 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 Sunriver, OR. 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 Sunriver.
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 Sunriver, OR. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Sunriver. 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 Sunriver, OR.

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

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