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

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