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

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