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

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