Certain rooms in your home never reach the temperature on the thermostat regardless of how long the HVAC runs in Marshalltown. Your energy bills are consistently higher than they should be for your usage in Marshalltown, IA. The HVAC system runs nearly continuously in hot or cold weather without the home ever reaching a comfortable temperature in Marshalltown. You have had the equipment checked and the technician said the system is working correctly in Marshalltown, IA. If the equipment is producing conditioned air correctly but the home is not comfortable and the bills are high, the problem is almost certainly in the distribution system in Marshalltown. Specifically, in duct leaks that are allowing conditioned air to escape into unconditioned spaces before it reaches the rooms in Marshalltown, IA.
Duct leaks are gaps, cracks, and unsealed joints throughout the duct system that allow conditioned air to escape from the supply ducts before it reaches the supply registers, and that allow unconditioned air to be drawn into the return ducts before it reaches the filter and air handler in Marshalltown. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Marshalltown, IA. 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 Marshalltown.

Systematic leak location to identify every specific leak point in Marshalltown. Correct sealant materials applied to every leak point in Marshalltown, IA. Pressure testing after repair to confirm the result with measured numbers in Marshalltown. And a guarantee on every repair in Marshalltown, IA. Call now for same-day scheduling in Marshalltown.
Duct damage is physical structural failure of the duct itself in Marshalltown. A disconnected section. A torn flexible duct. A collapsed run in Marshalltown, IA. Duct leaks are air loss through the joints, seams, and connections of a structurally intact duct system in Marshalltown. Both require different responses in Marshalltown, IA. Duct damage requires physical repair or replacement of the damaged section in Marshalltown. Duct damage requires physical repair or replacement of the damaged section. Duct leaks require sealant application to the leaking joints and connections. Duct leaks require sealant application to the leaking joints and connections in Marshalltown, IA. A duct system can have both damage and leaks simultaneously, or either one without the other in Marshalltown. Air America assesses for both during every duct leak repair service in Marshalltown, IA.
Every connection between duct sections is a potential leak point in Marshalltown, IA. In sheet metal duct systems, the transverse joints where sections connect and the longitudinal seams along each section are leak sources if not sealed in Marshalltown. In most residential installations, these joints were mechanically fastened without sealant during installation in Marshalltown, IA. 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 Marshalltown.
Branch takeoffs are the fittings that split conditioned air from the main trunk line into the individual branch duct runs serving each room in Marshalltown. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Marshalltown, IA. Branch takeoff leaks are among the largest individual leak points in typical residential duct systems because of the size of the connection and the pressure differential at the point where the trunk line splits into branches in Marshalltown.
The register boot is the fitting that connects the branch duct run to the wall, ceiling, or floor opening where the supply register mounts in Marshalltown, 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 Marshalltown. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Marshalltown, IA.
The supply plenum and return plenum connect the duct system to the air handler in Marshalltown. Plenum seams and the connections between the plenum and the air handler cabinet are often poorly sealed in residential installations in Marshalltown, IA. Leaks at the supply plenum lose conditioned air before it enters any of the branch duct runs in Marshalltown. Leaks at the return plenum draw unconditioned air from the mechanical room directly into the air handler, bypassing the filter in Marshalltown, IA.
The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage before it reaches the living spaces in Marshalltown, IA. In systems with particularly poor initial installation or with sealant that has failed over time, the loss can exceed 30 percent in Marshalltown.
Supply duct leakage in the spaces between branch duct connections and the registers means the rooms furthest from the air handler receive less conditioned air than they were designed to receive in Marshalltown. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in Marshalltown, IA. The room that is always too hot in summer and too cold in winter is often a room at the end of a duct run with multiple unsealed joints in Marshalltown.
Return duct leaks draw air from the surrounding space into the return airstream in Marshalltown. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Marshalltown, IA. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Marshalltown. This unconditioned air bypasses the filter and is distributed throughout the home in Marshalltown, IA. Repairing return duct leaks eliminates this pathway and limits the circulated air to what is drawn from the living spaces in Marshalltown.
Air America performs a duct pressure test before any leak repair begins in Marshalltown, IA. A calibrated fan is connected to the duct system and the system is pressurized to a standard test pressure in Marshalltown. The airflow required to maintain that pressure is measured in Marshalltown, IA. The measured airflow represents the total leakage rate of the system and provides the baseline for comparing before and after repair performance in Marshalltown.
With the system pressurized, Air America technicians systematically work through the accessible duct system to locate every specific leak point in Marshalltown. Every branch takeoff. Every duct joint connection. Every register boot connection. Every plenum seam and air handler connection in Marshalltown, IA. Every identified leak point is marked for sealing in Marshalltown.
Air America selects the correct sealant for each specific leak point based on the duct type, the joint configuration, and the access conditions in Marshalltown, IA. Mastic duct sealant for most duct joint and connection applications in Marshalltown. UL 181-rated foil tape for specific sheet metal seam applications in Marshalltown, IA. The correct material for the specific application in Marshalltown.
Air America systematically seals every identified leak point in the accessible duct system in Marshalltown. Mastic applied at the correct thickness to cover the full joint gap and bond to the duct surfaces on both sides in Marshalltown, IA. UL 181-rated tape applied with adequate overlap and firm pressure for complete adhesion in Marshalltown. Every identified leak point addressed before the post-repair pressure test in Marshalltown, IA.
After all identified leak points are sealed, Air America repeats the pressure test to measure the post-repair leakage rate in Marshalltown, IA. The before and after measurements quantify the leakage reduction achieved by the repair in Marshalltown. The post-repair test confirms the repair produced meaningful improvement and provides documented evidence of the result in Marshalltown, IA.
Mastic is a water-based sealant specifically formulated for duct system applications in Marshalltown, IA. It remains flexible after curing and maintains its seal through the expansion and contraction that duct systems experience during thermal cycling in Marshalltown. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Marshalltown, IA. Mastic is the professional standard for duct leak repair in Marshalltown.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Marshalltown. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Marshalltown, IA. Appropriate for specific sheet metal seam applications where a clean, smooth seal is needed in Marshalltown.
