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

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

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