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