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