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

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 Start. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Start, LA. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Start. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Start, LA. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Start.
Every connection between duct sections is a potential leak point in Start, LA. In most residential installations, these joints were mechanically fastened without sealant during installation in Start. 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 Start, LA.
Branch takeoffs split conditioned air from the main trunk line into the individual branch runs serving each room in Start. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Start, LA. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems in Start.
The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Start, LA. 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 Start. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Start, LA.
Systems sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion from temperature cycling in Start. Standard duct tape on duct joints typically fails within three to five seasons of thermal cycling in Start, LA. Joints that were sealed with standard tape appear sealed when first applied and are open to leakage again within a few years in Start.
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 Start. The conditioned air that leaks out before reaching the register does not reach the room in Start, LA. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in Start. 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 Start, LA.
Return duct leaks draw air from the surrounding unconditioned space into the return airstream in Start. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Start, LA. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Start. This unconditioned air bypasses the filter and is distributed throughout the home in Start, LA.
MBM Air Duct Cleaning performs a duct pressure test before any sealing begins in Start, LA. A calibrated fan is connected to the duct system and pressurized to a standard test pressure in Start. The measured airflow represents the total leakage rate and provides the baseline for comparing with the post-sealing result in Start, LA.
With the system pressurized, MBM technicians work through the accessible duct system to locate every specific leak point in Start. Every branch takeoff. Every duct joint. Every register boot connection. Every plenum seam and air handler connection in Start, LA. Every identified leak point is marked for sealing in Start.
Mastic sealant for most duct joint and connection applications in Start, LA. UL 181-rated foil tape for specific sheet metal seam applications in Start. The correct material for the specific application in Start, LA.
MBM systematically seals every identified leak point in the accessible duct system in Start. Mastic applied at the correct thickness to cover the full joint gap and bond to the duct surfaces on both sides in Start, LA. Every identified leak point addressed before the post-sealing pressure test in Start.
After all identified leak points are sealed, MBM repeats the pressure test to measure the post-sealing leakage rate in Start, LA. The before and after measurements quantify the leakage reduction achieved by the sealing in Start. Documented evidence of the result provided to the homeowner in Start, LA.
Mastic is a water-based sealant specifically formulated for duct system applications in Start, LA. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience in Start. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Start, LA.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Start. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Start, LA. Appropriate for specific sheet metal seam applications in Start.
Standard silver duct tape is not rated for duct system applications in Start, LA. Its rubber-based adhesive dries and loses adhesion from temperature cycling in Start. MBM Air Duct Cleaning never uses standard duct tape for duct sealing work in Start, LA.
MBM performs pressure testing before and after every duct sealing service in Start, LA. The before and after measurements document the leakage reduction achieved in Start. Documented improvement, not assumed improvement in Start, LA.
MBM seals every identified leak point in the accessible duct system in Start. Not a representative sample. Not the most obvious points only in Start, LA. Every identified leak point in Start.
Mastic sealant and UL 181-rated foil tape that maintain their effectiveness through the thermal cycling of long-term HVAC operation in Start, LA. Never standard duct tape in Start.
Every MBM Air Duct Cleaning duct sealing service is guaranteed in Start. If the sealing does not produce the expected improvement within the guarantee period, we return and address it at no additional charge in Start, LA.
All pricing confirmed upfront before work begins in Start. No surprises in Start, LA.
A sealing service that reduces leakage by 15 to 20 percentage points returns that proportional energy cost reduction on every subsequent energy bill in Start, LA. For a home spending $200 per month on heating and cooling, a 15 percent leakage reduction saves approximately $30 per month in Start. A sealing service costing $500 to $1,000 pays for itself in energy savings within 18 to 36 months in most cases in Start, LA. Every month after payback is net return on the investment in Start.
