Your energy bills are higher than they should be for the amount of heating and cooling your home requires in Crozet. Certain rooms will not reach the right temperature regardless of how long the HVAC runs in Crozet, VA. You have had the equipment checked and it is working correctly in Crozet. 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 Crozet, 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 Crozet.
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 Crozet, VA. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Crozet. 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 Crozet, 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 Crozet. A supply duct carrying cold conditioned air through a 130-degree summer attic cycles through extreme temperatures with every cooling cycle in Crozet, VA. Standard duct tape adhesive is not formulated for this cycling and fails within a few seasons in Crozet. Mastic sealant remains flexible after curing and maintains its seal through years of thermal cycling in Crozet, VA. UL 181-rated foil tape maintains adhesion for 20 years or more in normal duct system conditions in Crozet.
Every connection between duct sections is a potential leak point in Crozet, VA. In most residential installations, these joints were mechanically fastened without sealant during installation in Crozet. 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 Crozet, VA.
Branch takeoffs split conditioned air from the main trunk line into the individual branch runs serving each room in Crozet. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Crozet, VA. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems in Crozet.
The register boot connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Crozet, 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 Crozet. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Crozet, VA.
Systems sealed with standard duct tape develop leakage as the tape dries, cracks, and loses adhesion from temperature cycling in Crozet. Standard duct tape on duct joints typically fails within three to five seasons of thermal cycling in Crozet, VA. Joints that were sealed with standard tape appear sealed when first applied and are open to leakage again within a few years in Crozet.
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 Crozet. The conditioned air that leaks out before reaching the register does not reach the room in Crozet, 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 Crozet. 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 Crozet, VA.
Return duct leaks draw air from the surrounding unconditioned space into the return airstream in Crozet. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Crozet, VA. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Crozet. This unconditioned air bypasses the filter and is distributed throughout the home in Crozet, VA.
MBM Air Duct Cleaning performs a duct pressure test before any sealing begins in Crozet, VA. A calibrated fan is connected to the duct system and pressurized to a standard test pressure in Crozet. The measured airflow represents the total leakage rate and provides the baseline for comparing with the post-sealing result in Crozet, VA.
With the system pressurized, MBM technicians work through the accessible duct system to locate every specific leak point in Crozet. Every branch takeoff. Every duct joint. Every register boot connection. Every plenum seam and air handler connection in Crozet, VA. Every identified leak point is marked for sealing in Crozet.
Mastic sealant for most duct joint and connection applications in Crozet, VA. UL 181-rated foil tape for specific sheet metal seam applications in Crozet. The correct material for the specific application in Crozet, VA.
MBM systematically seals every identified leak point in the accessible duct system in Crozet. Mastic applied at the correct thickness to cover the full joint gap and bond to the duct surfaces on both sides in Crozet, VA. Every identified leak point addressed before the post-sealing pressure test in Crozet.
After all identified leak points are sealed, MBM repeats the pressure test to measure the post-sealing leakage rate in Crozet, VA. The before and after measurements quantify the leakage reduction achieved by the sealing in Crozet. Documented evidence of the result provided to the homeowner in Crozet, VA.
Mastic is a water-based sealant specifically formulated for duct system applications in Crozet, VA. It remains flexible after curing, maintaining its seal through the thermal cycling that duct systems experience in Crozet. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Crozet, VA.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Crozet. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Crozet, VA. Appropriate for specific sheet metal seam applications in Crozet.
Standard silver duct tape is not rated for duct system applications in Crozet, VA. Its rubber-based adhesive dries and loses adhesion from temperature cycling in Crozet. MBM Air Duct Cleaning never uses standard duct tape for duct sealing work in Crozet, VA.
MBM performs pressure testing before and after every duct sealing service in Crozet, VA. The before and after measurements document the leakage reduction achieved in Crozet. Documented improvement, not assumed improvement in Crozet, VA.

Every MBM Air Duct Cleaning duct sealing service is guaranteed in Crozet. If the sealing does not produce the expected improvement within the guarantee period, we return and address it at no additional charge in Crozet, VA.
All pricing confirmed upfront before work begins in Crozet. No surprises in Crozet, VA.
A sealing service that reduces leakage by 15 to 20 percentage points returns that proportional energy cost reduction on every subsequent energy bill in Crozet, VA. For a home spending $200 per month on heating and cooling, a 15 percent leakage reduction saves approximately $30 per month in Crozet. A sealing service costing $500 to $1,000 pays for itself in energy savings within 18 to 36 months in most cases in Crozet, VA. Every month after payback is net return on the investment in Crozet.
