Leaky air ducts are among the most significant sources of energy waste in homes, with typical duct systems losing 20-40% of heated or cooled air before it reaches living spaces. This wasted energy translates directly to higher utility bills, inconsistent room temperatures, and HVAC systems working harder than necessary. Professional duct sealing addresses these leaks, dramatically improving efficiency, comfort, and system performance.

As duct sealing specialists serving Santa Clarita Valley, we use advanced techniques to identify and seal leaks throughout your duct system. Whether your ducts are easily accessible or hidden behind walls and ceilings, we have solutions to dramatically reduce air leakage and improve your home’s comfort and efficiency.

How Much Energy Do Leaky Ducts Waste?

Research by the U.S. Department of Energy shows typical duct systems lose 20-40% of conditioned air through leaks, gaps, and poor connections. In Santa Clarita, where air conditioning runs extensively during summer months, this waste significantly impacts energy bills. For a home spending $2,000 annually on heating and cooling, duct leakage could waste $400-$800 each year. Over a typical duct system’s 20-30 year lifespan, that’s $8,000-$24,000 in wasted energy.

Professional duct sealing typically reduces leakage to under 6% as required by California Title 24, recovering most of this wasted energy and delivering substantial savings.

Comfort Problems from Leaky Ducts

Duct leakage causes problems beyond high energy bills. Uneven temperatures result when some rooms receive insufficient airflow due to air escaping before reaching those areas. Increased dust and allergens enter when return duct leaks pull in contaminated air from attics, crawl spaces, or wall cavities. HVAC strain occurs as systems run longer trying to compensate for lost air, leading to premature failure. Humidity problems develop when conditioned air escapes before dehumidifying living spaces. Reduced indoor air quality results from unconditioned contaminated air entering the system through return leaks.

Sealing these leaks addresses all these issues simultaneously, improving comfort while reducing energy waste.

California Title 24 Duct Sealing Requirements

California’s 2025 Building Energy Efficiency Standards effective January 2026 require duct leakage testing for all new duct systems and when existing systems are modified. Standards mandate total duct leakage not exceeding 6% of system airflow for new construction and major modifications, leakage to outside not exceeding 12% of system airflow for existing systems, testing performed by certified HERS raters using calibrated equipment, and documented results submitted to building departments for permit closure.

We handle all testing and documentation, ensuring your duct system meets these requirements and qualifies for utility rebates when available.

Our Duct Sealing Process

Step 1: Comprehensive Duct Leakage Testing

We begin every duct sealing project with precise measurement of existing leakage. Using calibrated duct blaster equipment, we measure total leakage showing air escaping anywhere in the system and leakage to outside measuring air escaping to unconditioned spaces. This testing establishes baseline leakage levels and identifies areas requiring attention, documenting improvement after sealing work.

Step 2: Leak Detection and Mapping

Beyond measuring total leakage, we identify specific leak locations using pressure testing isolating problem areas, smoke testing revealing airflow patterns, thermal imaging identifying temperature differences indicating leaks, and visual inspection of accessible ductwork. This comprehensive approach ensures we address all significant leaks, not just obvious ones.

Step 3: Professional Sealing

We use proven sealing methods appropriate for each situation. Traditional mastic sealing applies water-based mastic sealant to joints and seams, metal-backed tape for reinforcement, and mechanical fasteners ensuring long-term integrity. This hands-on approach works well for accessible ductwork in attics and crawl spaces. Aeroseal technology seals ducts from inside using patented polymer particles that adhere to leak edges, sealing ducts regardless of accessibility, and achieving superior results often reducing leakage by 90% or more.

Step 4: Post-Sealing Verification

After sealing, we re-test your duct system verifying leakage reduction, confirming compliance with Title 24 standards, documenting improvements for rebate programs, and providing before-and-after comparison showing results. This verification ensures you receive the energy savings and comfort improvements you’re paying for.

Duct Sealing Methods

Traditional Mastic and Tape Sealing

For accessible ductwork, traditional sealing provides durable long-lasting results. We use water-based mastic sealant applied to all joints and connections, metal-backed UL 181 tape never ordinary duct tape which degrades rapidly, mechanical fasteners on connections for added security, and insulation over sealed joints in unconditioned spaces. This method requires access to ductwork but provides excellent results when properly executed.

Aeroseal Duct Sealing Technology

Aeroseal represents a revolutionary approach to duct sealing, particularly valuable for ducts hidden in walls, concrete slabs, or otherwise inaccessible locations. The process involves blocking all registers and creating pressure in the duct system, introducing aerosolized sealant particles throughout the ductwork, particles adhering to leak edges and building up until holes are sealed, and computer monitoring showing real-time sealing progress and final results.

Aeroseal typically seals 95% or more of leakage, achieving results impossible with traditional methods. It’s particularly effective for sealing ductwork in finished homes where accessing ducts would require destructive demolition

When to Consider Duct Sealing

Duct sealing provides the most value in certain situations including homes with rooms that are always too hot or too cold, high energy bills relative to home size and climate, dusty homes despite regular cleaning, HVAC systems that run constantly without achieving comfort, homes with ducts in unconditioned spaces like attics or crawl spaces, and before installing new HVAC equipment to maximize system efficiency. If you’re experiencing any of these issues, duct sealing likely offers substantial benefits.

Duct Sealing vs. Duct Replacement

Sometimes homeowners wonder whether to seal existing ducts or replace them entirely. Duct sealing works well when ductwork is structurally sound, leakage is the primary problem, and ducts are properly sized for your system. Duct replacement may be better when ducts are severely damaged or deteriorated, sizing is inadequate for current equipment, or major layout changes are needed for home modifications. We provide honest assessments helping you choose the most cost-effective approach for your situation.

Available Rebates and Incentives

Southern California Edison and other utilities occasionally offer rebates for duct sealing as part of home energy efficiency programs. While rebate availability varies, we monitor current programs and help customers access available incentives. Duct sealing often qualifies for financing through utility-sponsored programs with favorable terms.
