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

Duct damage is physical structural failure of the duct itself in St. Louis Park. A disconnected section. A torn flexible duct. A collapsed run in St. Louis Park, MN. Duct leaks are air loss through the joints, seams, and connections of a structurally intact duct system in St. Louis Park. Both require different responses in St. Louis Park, MN. Duct damage requires physical repair or replacement of the damaged section in St. Louis Park. 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 St. Louis Park, MN. A duct system can have both damage and leaks simultaneously, or either one without the other in St. Louis Park. Air America assesses for both during every duct leak repair service in St. Louis Park, MN.
Every connection between duct sections is a potential leak point in St. Louis Park, 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 St. Louis Park. In most residential installations, these joints were mechanically fastened without sealant during installation in St. Louis Park, 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 St. Louis Park.
Branch takeoffs are the fittings that split conditioned air from the main trunk line into the individual branch duct runs serving each room in St. Louis Park. They have multiple edges and angles that create significant potential leak area if not correctly sealed in St. Louis Park, 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 St. Louis Park.
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 St. Louis Park, 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 St. Louis Park. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in St. Louis Park, MN.
The supply plenum and return plenum connect the duct system to the air handler in St. Louis Park. Plenum seams and the connections between the plenum and the air handler cabinet are often poorly sealed in residential installations in St. Louis Park, MN. Leaks at the supply plenum lose conditioned air before it enters any of the branch duct runs in St. Louis Park. Leaks at the return plenum draw unconditioned air from the mechanical room directly into the air handler, bypassing the filter in St. Louis Park, 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 St. Louis Park, MN. In systems with particularly poor initial installation or with sealant that has failed over time, the loss can exceed 30 percent in St. Louis Park.
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 St. Louis Park. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in St. Louis Park, 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 St. Louis Park.
Return duct leaks draw air from the surrounding space into the return airstream in St. Louis Park. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in St. Louis Park, MN. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in St. Louis Park. This unconditioned air bypasses the filter and is distributed throughout the home in St. Louis Park, MN. Repairing return duct leaks eliminates this pathway and limits the circulated air to what is drawn from the living spaces in St. Louis Park.
Air America performs a duct pressure test before any leak repair begins in St. Louis Park, MN. A calibrated fan is connected to the duct system and the system is pressurized to a standard test pressure in St. Louis Park. The airflow required to maintain that pressure is measured in St. Louis Park, MN. The measured airflow represents the total leakage rate of the system and provides the baseline for comparing before and after repair performance in St. Louis Park.
With the system pressurized, Air America technicians systematically work through the accessible duct system to locate every specific leak point in St. Louis Park. Every branch takeoff. Every duct joint connection. Every register boot connection. Every plenum seam and air handler connection in St. Louis Park, MN. Every identified leak point is marked for sealing in St. Louis Park.
