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

Duct damage is physical structural failure of the duct itself in La Verne. A disconnected section. A torn flexible duct. A collapsed run in La Verne, CA. Duct leaks are air loss through the joints, seams, and connections of a structurally intact duct system in La Verne. Both require different responses in La Verne, CA. Duct damage requires physical repair or replacement of the damaged section in La Verne. 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 La Verne, CA. A duct system can have both damage and leaks simultaneously, or either one without the other in La Verne. Air America assesses for both during every duct leak repair service in La Verne, CA.
Every connection between duct sections is a potential leak point in La Verne, 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 La Verne. In most residential installations, these joints were mechanically fastened without sealant during installation in La Verne, 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 La Verne.
Branch takeoffs are the fittings that split conditioned air from the main trunk line into the individual branch duct runs serving each room in La Verne. They have multiple edges and angles that create significant potential leak area if not correctly sealed in La Verne, 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 La Verne.
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 La Verne, 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 La Verne. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in La Verne, CA.
The supply plenum and return plenum connect the duct system to the air handler in La Verne. Plenum seams and the connections between the plenum and the air handler cabinet are often poorly sealed in residential installations in La Verne, CA. Leaks at the supply plenum lose conditioned air before it enters any of the branch duct runs in La Verne. Leaks at the return plenum draw unconditioned air from the mechanical room directly into the air handler, bypassing the filter in La Verne, 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 La Verne, CA. In systems with particularly poor initial installation or with sealant that has failed over time, the loss can exceed 30 percent in La Verne.
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 La Verne. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in La Verne, 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 La Verne.
Return duct leaks draw air from the surrounding space into the return airstream in La Verne. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in La Verne, CA. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in La Verne. This unconditioned air bypasses the filter and is distributed throughout the home in La Verne, CA. Repairing return duct leaks eliminates this pathway and limits the circulated air to what is drawn from the living spaces in La Verne.
Air America performs a duct pressure test before any leak repair begins in La Verne, CA. A calibrated fan is connected to the duct system and the system is pressurized to a standard test pressure in La Verne. The airflow required to maintain that pressure is measured in La Verne, CA. The measured airflow represents the total leakage rate of the system and provides the baseline for comparing before and after repair performance in La Verne.
With the system pressurized, Air America technicians systematically work through the accessible duct system to locate every specific leak point in La Verne. Every branch takeoff. Every duct joint connection. Every register boot connection. Every plenum seam and air handler connection in La Verne, CA. Every identified leak point is marked for sealing in La Verne.
Air America selects the correct sealant for each specific leak point based on the duct type, the joint configuration, and the access conditions in La Verne, CA. Mastic duct sealant for most duct joint and connection applications in La Verne. UL 181-rated foil tape for specific sheet metal seam applications in La Verne, CA. The correct material for the specific application in La Verne.
Air America systematically seals every identified leak point in the accessible duct system in La Verne. Mastic applied at the correct thickness to cover the full joint gap and bond to the duct surfaces on both sides in La Verne, CA. UL 181-rated tape applied with adequate overlap and firm pressure for complete adhesion in La Verne. Every identified leak point addressed before the post-repair pressure test in La Verne, CA.
After all identified leak points are sealed, Air America repeats the pressure test to measure the post-repair leakage rate in La Verne, CA. The before and after measurements quantify the leakage reduction achieved by the repair in La Verne. The post-repair test confirms the repair produced meaningful improvement and provides documented evidence of the result in La Verne, CA.
Mastic is a water-based sealant specifically formulated for duct system applications in La Verne, CA. It remains flexible after curing and maintains its seal through the expansion and contraction that duct systems experience during thermal cycling in La Verne. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in La Verne, CA. Mastic is the professional standard for duct leak repair in La Verne.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in La Verne. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in La Verne, CA. Appropriate for specific sheet metal seam applications where a clean, smooth seal is needed in La Verne.
Standard silver duct tape is not rated for duct system applications in La Verne, CA. Its rubber-based adhesive dries and loses adhesion from temperature cycling in La Verne. Standard duct tape on duct joints fails within a few heating and cooling seasons in La Verne, CA. Air America never uses standard duct tape for duct leak repair in La Verne.
Aeroseal seals leaks from inside the duct system in La Verne. Aerosolized sealant particles travel with the airstream to leak points where they accumulate and seal the gap in La Verne, CA. Effective for sealing leaks in duct sections that cannot be physically reached for manual sealant application in La Verne.
