Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Otis Orchards-East Farms. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Otis Orchards-East Farms, WA. You have had the equipment checked and it is working correctly in Otis Orchards-East Farms. 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 Otis Orchards-East Farms, 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 Otis Orchards-East Farms.
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 Otis Orchards-East Farms, WA. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Otis Orchards-East Farms. 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 Otis Orchards-East Farms, 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 Otis Orchards-East Farms. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Otis Orchards-East Farms, WA. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Otis Orchards-East Farms. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Otis Orchards-East Farms, WA. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Otis Orchards-East Farms.
Every connection between duct sections is a potential leak point in Otis Orchards-East Farms, WA. In most residential installations, these joints were mechanically fastened without sealant during installation in Otis Orchards-East Farms. 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 Otis Orchards-East Farms, WA.
Branch takeoffs split conditioned air from the main trunk line into the individual branch runs serving each room in Otis Orchards-East Farms. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Otis Orchards-East Farms, WA. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems in Otis Orchards-East Farms.
The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Otis Orchards-East Farms, 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 Otis Orchards-East Farms. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Otis Orchards-East Farms, WA.
Systems sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion from temperature cycling in Otis Orchards-East Farms. Standard duct tape on duct joints typically fails within three to five seasons of thermal cycling in Otis Orchards-East Farms, WA. Joints that were sealed with standard tape appear sealed when first applied and are open to leakage again within a few years in Otis Orchards-East Farms.
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 Otis Orchards-East Farms. The conditioned air that leaks out before reaching the register does not reach the room in Otis Orchards-East Farms, 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 Otis Orchards-East Farms. 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 Otis Orchards-East Farms, WA.
Return duct leaks draw air from the surrounding unconditioned space into the return airstream in Otis Orchards-East Farms. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Otis Orchards-East Farms, WA. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Otis Orchards-East Farms. This unconditioned air bypasses the filter and is distributed throughout the home in Otis Orchards-East Farms, WA.
MBM Air Duct Cleaning performs a duct pressure test before any sealing begins in Otis Orchards-East Farms, WA. A calibrated fan is connected to the duct system and pressurized to a standard test pressure in Otis Orchards-East Farms. The measured airflow represents the total leakage rate and provides the baseline for comparing with the post-sealing result in Otis Orchards-East Farms, WA.
With the system pressurized, MBM technicians work through the accessible duct system to locate every specific leak point in Otis Orchards-East Farms. Every branch takeoff. Every duct joint. Every register boot connection. Every plenum seam and air handler connection in Otis Orchards-East Farms, WA. Every identified leak point is marked for sealing in Otis Orchards-East Farms.

Documented evidence of the result provided to the homeowner in Otis Orchards-East Farms, WA.
Mastic is a water-based sealant specifically formulated for duct system applications in Otis Orchards-East Farms, WA. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience in Otis Orchards-East Farms. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Otis Orchards-East Farms, WA.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Otis Orchards-East Farms. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Otis Orchards-East Farms, WA. Appropriate for specific sheet metal seam applications in Otis Orchards-East Farms.
Standard silver duct tape is not rated for duct system applications in Otis Orchards-East Farms, WA. Its rubber-based adhesive dries and loses adhesion from temperature cycling in Otis Orchards-East Farms.
