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

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