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

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 Christiansburg. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Christiansburg, VA. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Christiansburg. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Christiansburg, VA. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Christiansburg.
Every connection between duct sections is a potential leak point in Christiansburg, VA. In most residential installations, these joints were mechanically fastened without sealant during installation in Christiansburg. 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 Christiansburg, VA.
Branch takeoffs split conditioned air from the main trunk line into the individual branch runs serving each room in Christiansburg. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Christiansburg, VA. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems in Christiansburg.
The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Christiansburg, VA. 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 Christiansburg. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Christiansburg, VA.
Systems sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion from temperature cycling in Christiansburg. Standard duct tape on duct joints typically fails within three to five seasons of thermal cycling in Christiansburg, VA. Joints that were sealed with standard tape appear sealed when first applied and are open to leakage again within a few years in Christiansburg.
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 Christiansburg. The conditioned air that leaks out before reaching the register does not reach the room in Christiansburg, VA. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in Christiansburg. 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 Christiansburg, VA.
Return duct leaks draw air from the surrounding unconditioned space into the return airstream in Christiansburg. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Christiansburg, VA. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Christiansburg. This unconditioned air bypasses the filter and is distributed throughout the home in Christiansburg, VA.
MBM Air Duct Cleaning performs a duct pressure test before any sealing begins in Christiansburg, VA. A calibrated fan is connected to the duct system and pressurized to a standard test pressure in Christiansburg. The measured airflow represents the total leakage rate and provides the baseline for comparing with the post-sealing result in Christiansburg, VA.
With the system pressurized, MBM technicians work through the accessible duct system to locate every specific leak point in Christiansburg. Every branch takeoff. Every duct joint. Every register boot connection. Every plenum seam and air handler connection in Christiansburg, VA. Every identified leak point is marked for sealing in Christiansburg.
Mastic sealant for most duct joint and connection applications in Christiansburg, VA. UL 181-rated foil tape for specific sheet metal seam applications in Christiansburg. The correct material for the specific application in Christiansburg, VA.

After all identified leak points are sealed, MBM repeats the pressure test to measure the post-sealing leakage rate in Christiansburg, VA. The before and after measurements quantify the leakage reduction achieved by the sealing in Christiansburg. Documented evidence of the result provided to the homeowner in Christiansburg, VA.
Mastic is a water-based sealant specifically formulated for duct system applications in Christiansburg, VA. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience in Christiansburg. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Christiansburg, VA.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Christiansburg. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Christiansburg, VA. Appropriate for specific sheet metal seam applications in Christiansburg.
