Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Cle Elum. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Cle Elum, WA. You have had the equipment checked and it is working correctly in Cle Elum. 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 Cle Elum, 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 Cle Elum.
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 Cle Elum, WA. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Cle Elum. 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 Cle Elum, 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 Cle Elum. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Cle Elum, WA. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Cle Elum. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Cle Elum, WA. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Cle Elum.
Every connection between duct sections is a potential leak point in Cle Elum, WA. In most residential installations, these joints were mechanically fastened without sealant during installation in Cle Elum. 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 Cle Elum, WA.
Branch takeoffs split conditioned air from the main trunk line into the individual branch runs serving each room in Cle Elum. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Cle Elum, WA. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems in Cle Elum.
The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Cle Elum, 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 Cle Elum. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Cle Elum, WA.
Systems sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion from temperature cycling in Cle Elum. Standard duct tape on duct joints typically fails within three to five seasons of thermal cycling in Cle Elum, WA. Joints that were sealed with standard tape appear sealed when first applied and are open to leakage again within a few years in Cle Elum.
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 Cle Elum. The conditioned air that leaks out before reaching the register does not reach the room in Cle Elum, 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 Cle Elum. 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 Cle Elum, WA.
Return duct leaks draw air from the surrounding unconditioned space into the return airstream in Cle Elum. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Cle Elum, WA. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Cle Elum. This unconditioned air bypasses the filter and is distributed throughout the home in Cle Elum, WA.
MBM Air Duct Cleaning performs a duct pressure test before any sealing begins in Cle Elum, WA. A calibrated fan is connected to the duct system and pressurized to a standard test pressure in Cle Elum. The measured airflow represents the total leakage rate and provides the baseline for comparing with the post-sealing result in Cle Elum, WA.
With the system pressurized, MBM technicians work through the accessible duct system to locate every specific leak point in Cle Elum. Every branch takeoff. Every duct joint. Every register boot connection. Every plenum seam and air handler connection in Cle Elum, WA. Every identified leak point is marked for sealing in Cle Elum.
Mastic sealant for most duct joint and connection applications in Cle Elum, WA. UL 181-rated foil tape for specific sheet metal seam applications in Cle Elum. The correct material for the specific application in Cle Elum, WA.
MBM systematically seals every identified leak point in the accessible duct system in Cle Elum. Mastic applied at the correct thickness to cover the full joint gap and bond to the duct surfaces on both sides in Cle Elum, WA. Every identified leak point addressed before the post-sealing pressure test in Cle Elum.
After all identified leak points are sealed, MBM repeats the pressure test to measure the post-sealing leakage rate in Cle Elum, WA. The before and after measurements quantify the leakage reduction achieved by the sealing in Cle Elum. Documented evidence of the result provided to the homeowner in Cle Elum, WA.
Mastic is a water-based sealant specifically formulated for duct system applications in Cle Elum, WA. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience in Cle Elum. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Cle Elum, WA.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Cle Elum. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Cle Elum, WA. Appropriate for specific sheet metal seam applications in Cle Elum.
Standard silver duct tape is not rated for duct system applications in Cle Elum, WA. Its rubber-based adhesive dries and loses adhesion from temperature cycling in Cle Elum. MBM Air Duct Cleaning never uses standard duct tape for duct sealing work in Cle Elum, WA.
MBM performs pressure testing before and after every duct sealing service in Cle Elum, WA. The before and after measurements document the leakage reduction achieved in Cle Elum. Documented improvement, not assumed improvement in Cle Elum, WA.
