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

Duct damage is physical structural failure of the duct itself in Dunnigan. A disconnected section. A torn flexible duct. A collapsed run in Dunnigan, CA. Duct leaks are air loss through the joints, seams, and connections of a structurally intact duct system in Dunnigan. Both require different responses in Dunnigan, CA. Duct damage requires physical repair or replacement of the damaged section in Dunnigan. 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 Dunnigan, CA. A duct system can have both damage and leaks simultaneously, or either one without the other in Dunnigan. Air America assesses for both during every duct leak repair service in Dunnigan, CA.
Every connection between duct sections is a potential leak point in Dunnigan, 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 Dunnigan. In most residential installations, these joints were mechanically fastened without sealant during installation in Dunnigan, 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 Dunnigan.
Branch takeoffs are the fittings that split conditioned air from the main trunk line into the individual branch duct runs serving each room in Dunnigan. They have multiple edges and angles that create significant potential leak area if not correctly sealed in Dunnigan, 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 Dunnigan.
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 Dunnigan, 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 Dunnigan. Conditioned air escaping at the boot level leaks into the wall or ceiling cavity rather than through the register into the room in Dunnigan, CA.
The supply plenum and return plenum connect the duct system to the air handler in Dunnigan. Plenum seams and the connections between the plenum and the air handler cabinet are often poorly sealed in residential installations in Dunnigan, CA. Leaks at the supply plenum lose conditioned air before it enters any of the branch duct runs in Dunnigan. Leaks at the return plenum draw unconditioned air from the mechanical room directly into the air handler, bypassing the filter in Dunnigan, 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 Dunnigan, CA. In systems with particularly poor initial installation or with sealant that has failed over time, the loss can exceed 30 percent in Dunnigan.
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 Dunnigan. Rooms at the end of long duct runs with multiple leak points along the way receive the cumulative effect of all those leaks in Dunnigan, 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 Dunnigan.
Return duct leaks draw air from the surrounding space into the return airstream in Dunnigan. A return duct leak in an attic draws hot, dusty attic air into the air handler in summer in Dunnigan, CA. A return duct leak in a crawl space draws crawl space air including moisture, mold spores, and soil particulate into the system in Dunnigan. This unconditioned air bypasses the filter and is distributed throughout the home in Dunnigan, CA. Repairing return duct leaks eliminates this pathway and limits the circulated air to what is drawn from the living spaces in Dunnigan.
Air America performs a duct pressure test before any leak repair begins in Dunnigan, CA. A calibrated fan is connected to the duct system and the system is pressurized to a standard test pressure in Dunnigan. The airflow required to maintain that pressure is measured in Dunnigan, CA. The measured airflow represents the total leakage rate of the system and provides the baseline for comparing before and after repair performance in Dunnigan.
With the system pressurized, Air America technicians systematically work through the accessible duct system to locate every specific leak point in Dunnigan. Every branch takeoff. Every duct joint connection. Every register boot connection. Every plenum seam and air handler connection in Dunnigan, CA. Every identified leak point is marked for sealing in Dunnigan.
Air America selects the correct sealant for each specific leak point based on the duct type, the joint configuration, and the access conditions in Dunnigan, CA. Mastic duct sealant for most duct joint and connection applications in Dunnigan. UL 181-rated foil tape for specific sheet metal seam applications in Dunnigan, CA. The correct material for the specific application in Dunnigan.
Air America systematically seals every identified leak point in the accessible duct system in Dunnigan. Mastic applied at the correct thickness to cover the full joint gap and bond to the duct surfaces on both sides in Dunnigan, CA. UL 181-rated tape applied with adequate overlap and firm pressure for complete adhesion in Dunnigan. Every identified leak point addressed before the post-repair pressure test in Dunnigan, CA.
After all identified leak points are sealed, Air America repeats the pressure test to measure the post-repair leakage rate in Dunnigan, CA. The before and after measurements quantify the leakage reduction achieved by the repair in Dunnigan. The post-repair test confirms the repair produced meaningful improvement and provides documented evidence of the result in Dunnigan, CA.
Mastic is a water-based sealant specifically formulated for duct system applications in Dunnigan, CA. It remains flexible after curing and maintains its seal through the expansion and contraction that duct systems experience during thermal cycling in Dunnigan. It does not dry out, crack, or lose adhesion from temperature cycling the way standard duct tape does in Dunnigan, CA. Mastic is the professional standard for duct leak repair in Dunnigan.
UL 181-rated foil tape is tested and rated specifically for HVAC duct applications in Dunnigan. Unlike standard duct tape, it maintains its adhesion through the temperature cycling of duct system operation in Dunnigan, CA. Appropriate for specific sheet metal seam applications where a clean, smooth seal is needed in Dunnigan.
Standard silver duct tape is not rated for duct system applications in Dunnigan, CA. Its rubber-based adhesive dries and loses adhesion from temperature cycling in Dunnigan.
