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

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

A sealing service that reduces leakage by 15 to 20 percentage points returns that proportional energy cost reduction on every subsequent energy bill in Kerrville, TX. For a home spending $200 per month on heating and cooling, a 15 percent leakage reduction saves approximately $30 per month in Kerrville. A sealing service costing $500 to $1,000 pays for itself in energy savings within 18 to 36 months in most cases in Kerrville, TX. Every month after payback is net return on the investment in Kerrville.
