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