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

Duct damage is physical structural failure of the duct itself in San Antonio. A disconnected section. A torn flexible duct. A collapsed run in San Antonio, FL. Duct leaks are air loss through the joints, seams, and connections of a structurally intact duct system in San Antonio. Both require different responses in San Antonio, FL. Duct damage requires physical repair or replacement of the damaged section in San Antonio. 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 San Antonio, FL. A duct system can have both damage and leaks simultaneously, or either one without the other in San Antonio. Air America assesses for both during every duct leak repair service in San Antonio, FL.
Every connection between duct sections is a potential leak point in San Antonio, FL. 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 San Antonio. In most residential installations, these joints were mechanically fastened without sealant during installation in San Antonio, FL. 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 San Antonio.
Branch takeoffs are the fittings that split conditioned air from the main trunk line into the individual branch duct runs serving each room in San Antonio. They have multiple edges and angles that create significant potential leak area if not correctly sealed in San Antonio, FL. 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 San Antonio.
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 San Antonio, FL. 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 San Antonio. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in San Antonio, FL.
The supply plenum and return plenum connect the duct system to the air handler in San Antonio. Plenum seams and the connections between the plenum and the air handler cabinet are often poorly sealed in residential installations in San Antonio, FL. Leaks at the supply plenum lose conditioned air before it enters any of the branch duct runs in San Antonio. Leaks at the return plenum draw unconditioned air from the mechanical room directly into the air handler, bypassing the filter in San Antonio, FL.
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 San Antonio, FL. In systems with particularly poor initial installation or with sealant that has failed over time, the loss can exceed 30 percent in San Antonio.
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 San Antonio. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in San Antonio, FL. 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 San Antonio.
Return duct leaks draw air from the surrounding space into the return airstream in San Antonio. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in San Antonio, FL. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in San Antonio. This unconditioned air bypasses the filter and is distributed throughout the home in San Antonio, FL. Repairing return duct leaks eliminates this pathway and limits the circulated air to what is drawn from the living spaces in San Antonio.
Air America performs a duct pressure test before any leak repair begins in San Antonio, FL. A calibrated fan is connected to the duct system and the system is pressurized to a standard test pressure in San Antonio. The airflow required to maintain that pressure is measured in San Antonio, FL. The measured airflow represents the total leakage rate of the system and provides the baseline for comparing before and after repair performance in San Antonio.
With the system pressurized, Air America technicians systematically work through the accessible duct system to locate every specific leak point in San Antonio. Every branch takeoff. Every duct joint connection. Every register boot connection. Every plenum seam and air handler connection in San Antonio, FL. Every identified leak point is marked for sealing in San Antonio.
Air America selects the correct sealant for each specific leak point based on the duct type, the joint configuration, and the access conditions in San Antonio, FL. Mastic duct sealant for most duct joint and connection applications in San Antonio. UL 181-rated foil tape for specific sheet metal seam applications in San Antonio, FL. The correct material for the specific application in San Antonio.
