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

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

All pricing confirmed upfront before work begins in Sonoma State University. No surprises in Sonoma State University, CA.
A sealing service that reduces leakage by 15 to 20 percentage points returns that proportional energy cost reduction on every subsequent energy bill in Sonoma State University, CA. For a home spending $200 per month on heating and cooling, a 15 percent leakage reduction saves approximately $30 per month in Sonoma State University. A sealing service costing $500 to $1,000 pays for itself in energy savings within 18 to 36 months in most cases in Sonoma State University, CA. Every month after payback is net return on the investment in Sonoma State University.
