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

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

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