Certain rooms in your home never reach the temperature on the thermostat regardless of how long the HVAC runs in Andover. Your energy bills are consistently higher than they should be for your usage in Andover, MN. The HVAC system runs nearly continuously in hot or cold weather without the home ever reaching a comfortable temperature in Andover. You have had the equipment checked and the technician said the system is working correctly in Andover, MN. 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 Andover. Specifically, in duct leaks that are allowing conditioned air to escape into unconditioned spaces before it reaches the rooms in Andover, MN.
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 Andover. The Department of Energy estimates that typical residential duct systems lose 20 to 30 percent of conditioned air through leakage in Andover, MN. 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 Andover.

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